3 Tips for Finding the Perfect Audio Recording Software for Your Courtroom

As a Court Administrator, investing in a court recording software that is easy to use, flexible and makes sharing recordings a simple task is critical to meet the guidelines of your role. My 25+ years of audio/video experience has allowed me to formulate this list of 3 factors to consider as you begin your search for the right software for your courtroom. I hope it’s helpful.

1. Base your search on your answers to the following questions:
    • How many channels of audio do I need to record simultaneously?
    • Do I have a docket I need to upload into the system for metadata or bookmarks purposes?
    • Do I need to import data from a case management system?
    • How will I be sharing or storing recordings: email, DVD, USB, a link?
    • Will I or any other users using a foot pedal to replay recordings?
    • What metadata fields are pertinent in each recording?
      • Ex: Case name, case number, case ID, Judge, time and date of record, court department, location, name of witness, defendant or any other pertinent information.

 

2. Consider the need for a media library. A media library stores your recordings in an on-premise or cloud-based application that can be accessed by as many or as little users with login credentials as you’d like. With a media library, users can….
    1. Search recordings by metadata
    2. Add bookmarks after recordings are finished
    3. Export and trim recordings
    4. Set up a user permissions hierarchy
    5. Isolate channels during playback and more

 

3. If you’ve decided to invest in a media library, the next step is to decide whether you’d like the storage to be on-premise or cloud-based. Before you make the decision, please read on to learn how they work…

An on-premise video library is an application installed at your location. It uses your computers and your hardware storage. Sometimes, the Information Technology specialist (IT) will install a “Virtual Server” on the existing hardware including an SQL application and the video library application. Subsequently, if the IT specialist configures the library correctly, it becomes a corporate cloud application. Cost-wise, normally on-premise applications are purchased and owned, with ongoing annual fees for updates and maintenance. The pros mainly concern security. Many legal entities are very reluctant to have sensitive information outside their physical control.

Cloud applications are very secure, but there are ongoing fees to consider. In the long term, an in-house facility is less expensive. The short term is more expensive as all hardware and software need to be procured as well as ongoing maintenance costs. Finally, there is a question of Internet access. If you always access the library from your internal Ethernet network, all is good. But if you require users to access the database from outside the internal network, the Internet connection will need updating to a much higher upload speed, to allow users access to the video library at the same time. The cloud has the same features as an on-premises installation except the application is based outside your locations in a “Data Center”. The Data Center is not your provider, it is a service purchased by your provider. Your provider rents rack space in the Data Center where the hardware is installed. The provider also rents a huge upload Internet connection allowing him to service many customers at the same time. The benefits of the Data Center are the enormous pipeline of data it can provide, and the very high levels of security to access the environment. The cloud service is generally offered on a monthly payment program. Naturally, the provider will require a signed contract and will charge for configuration and installation.

Short term it is less expensive, as there is no need to purchase equipment and staff-time to implement the solution. The connection to the library will be much faster and more accessible worldwide by many users simultaneously. The solution will cost more on a long-time basis. Even though the solution is very safe, there is a security issue perception, due to the fact that people other than your own staff are in charge of the hardware.

Once you’ve got an idea of what you want in a media library, storage and the specifications you’ll need to be fulfilled, you’re ready to begin booking appointments with vendors. Remember to be as transparent about what you want in these appointments, so you don’t waste any time on software that doesn’t fit your needs. Good luck!

6 Body Language Facts to Keep in Mind When Interviewing a Suspect

Scott Rouse is a behavior analyst and body language expert with a focus on healthcare. He holds multiple certificates in advanced interrogation training and has been trained alongside the FBI, Secret Service, U.S. Military Intelligence, and Dept. of defense. His extensive training, education, and practice of nonverbal communication has made Scott an expert and consultant to healthcare companies as well as law enforcement, Fortune 500 CEO’s, doctors, attorneys, executives, wealth managers, financial advisors, and entertainers.
We met with Scott to learn more about how body language plays a role in distinguishing true from false when conducting a suspect interview. See below for our 6 key takeaways…

blank

1. There are no absolutes:
There are no absolutes. No matter what anybody tells you, there’s not one body language cue or tell that’ll let you know that a person is being honest or telling the truth.

2. It’s crucial to get a baseline:
For a baseline, you want to talk to the suspect for a few minutes and see how they are acting when they think they’re in trouble or going to be in trouble. They’re worried, so their body is going to be a little bit off. Try to talk to them, get them calmed down a little bit. Then ask them questions that you know the answer to, see how they react. Where were they? Why did they do this?

Of course, everybody knows the Reid Technique, so we’ll start there. One of the first things you do is come in and say, “Hey, you know, it’s obvious you did this. We have all this evidence that shows you did.” Then you move forward from there and watch what they do. Sometimes they’ll start frowning and get really quiet. A lot of times they’ll get really loud. When I get that initial contact with them and I begin being aggressive; I’ll watch for to how angry they get on a 1 to 10 scale. If they go up to a 9 or 10 and stay there, a lot of times they’re not the suspect.

I’ve found research shows that if a person did something, when you give them that first initial, “Hey, it looks like you, we think you did this”, they get upset. They’ll go down fairly quickly and get a little quiet because they want to know all the information that you know about that situation. They don’t get fired up for very long after that. They may go to a 3 or 4 and come back down. But they’ll try to get information by watching you to see how much you know about them.

One of the main things that people think is that if someone lies to you is they’re going to break eye contact with you. However, that’s not true at all. What happens is your brain wants to keep looking at that person; they do this make sure you believe their lie. People think you start blinking a whole lot when you’re lying. That’s not true because your brain wants to keep those eyes up and to keep an eye on you, to make sure you believe what’s going on. If you don’t believe it, the brain will know to add what are called qualifiers to strengthen what I’m telling you to make it sound more believable.

There’s not one place you usually go for an interview. Obviously, you’re going to be looking at the face already. So that’s one of the first things to look at that. As you look at that person, you want to look at the entire person and the entire situation without letting them know that’s what you’re doing. So it’s important to take that into consideration and put the person in a situation in context with what’s going on right then. So, if I ask many questions and they start answering and start getting quiet toward the end, that’s what I refer to that as fading facts. That’s one thing I listen for. However, just because they’re talking to you quieter as we go along, doesn’t mean they’re lying.

It doesn’t mean they’re telling the truth either, When you start adding these things up, you can say “I think I’m dealing with somebody who’s not telling me the truth here”, or I’m thinking, “I think I’m dealing with somebody who’s telling me the truth”, or you still have to go through the entire process but you get a better idea of what you’re dealing with.

3. Barriers are a telling sign of comfort levels:
A barrier is something an interviewee may put in their hand or put their arm up on the table. Anything you put between you and the other person doesn’t matter. It could be yellow pads or a pen. Barriers don’t mean you’re lying or that you’re telling the truth. They just show you’re feeling uncomfortable. The main thing you’re looking for are the differences in comfort and discomfort. People who have read Joe Navarro books will know exactly where that comes from. Obviously in this situation, they’re going to be freaked out. Once I get them calmed down, we can and talking normally, because I can go in and say, I’m not a cop. I’m just here to find out what happened.”

4. Adapters are important factors to keep an eye on too:
Adapters are the things we use to self sooth to get rid of built up stress or tension from that situation. You’ve seen people rubbed their hands – that’s an adapter. Have you seen people cross one army rub their shoulder or pull on their face or their mouth or push on their face? That’s called facial distortion. They get from very small, to really big where people move around and move their arms or, or their legs or pull their shoulders together. So that lets you know, that someone is trying to get rid of that built up stress retention. Those are the first things I look for.

5. Making the interviewee comfortable is critical to get more information:
I want them to be comfortable. I want to be as nice to them as I can so they’ll like me because all they have to say is, are four words: “I want my lawyer”. You want to spend as much time with them as possible because the more time you spend with them, the more they’ll bond with you, the more you’ve got a chance to fire off that oxytocin the chemicals in the brain that make you bond with that person. Then they’ll want to tell you something. Some interviewers are taking an entirely different approach from that, so people will come straight on and come barrel in and “Hey, here’s what’s going on? What about so-and-so?” They think that confrontational style is the way to get more information but that’s not necessarily so.

6. The 7/38/55 rule of communication is a MYTH!
A lot of times in law enforcement, you hear these tales that everyone’s heard for years and years that are not true. Most of them are under the impression that there’s this thing called the 7/38/55 rule of communication. The 7/38/55 rule of communication says that 70% of your communication is words. You use 38% of your communications (the tone of voice you use). The 55%, (the rest of it) is body language. Words are only 7% so 93% of your communication is body language.

I called the guy who came up with this study back in the eighties and he said, “Hey man, this doesn’t sound right to me.” His name was Albert Mehrabian Rabin. I said, “well, what happened? Why people saying this?” He said, “before I tell you this, promise me, that when this comes up, you you’ll tell them what I’m telling you.” I said, “I’ll tell them”. And he said, “I did two different studies, one dealt with the tone of voice and one dealt with body language and they put them together. And somehow they’ve come up with this thing and it’s wrong. It’s not what I said. It’s invalid. Don’t use that.” To this day, when you go on the internet and you find a “body language expert” one of the first things out of their mouth is “communication is 7/38/55.

Tip from MaestroVision:
Record and replay your suspect interviews to see if there’s any body language cues you missed the first time. You can also use your recordings as an opportunity to find areas of improvement in your investigative interviewing process/techniques. First step: invest in a reliable, high quality interview recording system so you can capture every crucial detail of the interview and use it for evidence to move forward in the case. Our CEO, Claude Turcotte created an extensive guide outlining the key considerations for law enforcement when developing their interview room software, hardware, furniture and more.

Key Ingredients for Your Agency’s Trauma-Informed Soft Interview Room

We sat down with Tracy Matheson to speak more about her non-profit and the essential considerations for developing a trauma-informed interview room.

blank

These statistics from RAINN (Rape, Abuse & Incest National Network) may disturb you:

      • On average, there are 433,648 victims (age 12 or older) of rape and sexual assault each year in the United States.

      • Every 73 seconds an American is sexually assaulted.

      • Ages 12-34 are the highest risk years for rape and sexual assault.

In response to the growing need for services that demand justice for sexual assault survivors, law enforcement is increasingly taking measures to create resources that are trauma informed. According to Tracy Matheson, the President/Founder of Project Beloved – trauma-informed care is a practice that takes the body’s biological response to trauma into consideration.

Thus the soft interview room was born; a safe place for victims and witnesses to feel comfortable to share their story and provide crucial evidence that helps law enforcement get pertinent details about the case and suspect.

We sat down with Tracy Matheson to speak more about her non-profit and the essential considerations for developing a trauma informed interview room.

What is Project Beloved?

Project Beloved is a 501c3 non-profit that strives to educate, advocate, and collaborate to change the conversation about sexual assault and empower survivors to find their voices. Tracy Matheson’s daughter, Molly Jane was her inspiration for the non-profit as she was a victim of sexual assault and homicide in 2017. Some of the projects and initiatives employed by the organization include:

• The passing of Molly Jane’s Law which allows law enforcement agencies in Texas to communicate with one another through the use of ViCAP, which is administered by the FBI. ViCAP was created to help identify serial murderers and rapists and is available in all 50 states.

• The creation and distribution of Beloved Bundles. Beloved Bundles are distributed to survivors of sexual assault when they go to the hospital for a forensic exam (otherwise known as a “rape kit”) and their belongings are seized as evidence. The Bundles include: clothing, undergarments, hygiene products and other necessary items.

• The Molly Jane Matheson Memorial Scholarship is awarded to social work students at the University of Arkansas on an annual basis in the amount of $2200 each in honor of Molly’s 22 years.

• The installation of Soft Interview Rooms at law enforcement agencies. Project beloved assists law enforcement agencies with the funding, layout and installation of Soft Interview Rooms at their department. As of today, they have installed 24 soft interview room at police stations, child advocacy centers and organizations which serve vulnerable youth throughout the US. In 2021, they plan to install 12 more.

Donate to Project Beloved to support their mission of educating, advocating, and collaborating to change the conversation about sexual assault and empower survivors to find their voices.

The 9 Critical Elements of an Effective Trauma-Informed Soft Interview Room

Is your organization interested in acquiring a Soft Interview Room? Here are the 9 factors that Tracy recommends taking into consideration when building an effective trauma informed Soft Interview Room.

Victim Services

1. Privacy

Ensure the room is private. Sound proofing the walls is a good option to consider for less distractions, unwanted or loud noises that can interrupt the interview and make the interviewee feel less safe and secure.

StarWitness Interview Recording

2. Color

Consider what color is on the wall. Use pleasing, comfortable, soft colors like blues and greens.

CaseCracker Interview Recording

3. Furniture

Use furniture with soft fabrics that are comfortable to sit in. Find chairs that swivel to allow greater movement for a victim being interviewed.

4. Lighting

Consider the lighting being used to bring a positive, living room type of setting. Fluorescent lighting and lamps are preferable. If the room has a window, the natural light and view can make the space feel more open. If the room doesn’t have a window, invest in a mirror but ensure it’s not facing the interviewee so they don’t have to stare at themselves during the interview.

5. Blankets

Incorporate blankets that are weighted and soft.

6. Accessories

Create a safe vibe with diffusers (use oils that are soothing to the senses) and accessories like artwork that are pleasing to look at.

Project Beloved

7. Carpeting

Use carpeting like an area rug. Avoid bare hardwood floors.

Trauma Informed Investigations

8. Cameras

Utilize subtle, covert cameras (although the interviewee is informed they’re being recorded) These cameras are less obtrusive.

Liberty Recording

9. The Interview

Make sure you’re well versed on trauma informed investigations. Tracy describes it as “Having a deep engrained understanding of what trauma is and how it affects a person who has experienced violence or a sexual assault. It’s woven into the fiber of your being so you respond from a place of understanding. Everything you do is done to minimize or reduce the trauma that they’ve experienced rather than re-traumatize or add to the trauma. It’s a mind shift. Once I understand trauma, it’s going to change everything that I do and say when I encounter someone who has experienced trauma.”

Above are some of the examples of soft interview rooms that Project Beloved has installed at various police stations throughout the US.

    Tech Tip Tuesday – How Many Cameras are Recommended for an Interview Room?

    Presenting Tech Tip Tuesdays! Where broadcast experts answer your commonly asked A/V questions!

    Do you have an A/V question you’d like us to answer? Send it to info@maestrovision.com and it just might be featured in a future video!

    Question

    How Many Cameras do you Recommend for an Interview Room?

    Answer

    We recommend strategically placing two cameras in an interview room.

    The first should be a wide-angle camera positioned in a corner where it can capture the entire room.

    For the second camera, position a varifocal one to capture both the interviewee’s full body and the corner where the first camera is placed.

    If there’s a whiteboard or any other object in the room you want to be recorded, make sure to position a third camera if not already captured.

    Interview recording requirements vary for each organization, therefore the number and placement of cameras depend on your specific needs.

    A Guide to Different Types of Cameras Used in Police Interview Recordings

    If you’re wondering what type of camera to use in your interview room, look no further. In this article, we’ll explain the three main types of cameras that are used for interview recordings.

    If you’re wondering what type of camera to use in your interview room, look no further. In this article, we’ll explain the three main types of cameras that are used for interview recordings: IP, USB and HD-SDI. We will compare each of them and provide their pros and cons.

    blank

    IP CAMERAS

    IP stands for Internet Protocol. IP cameras are the most popular on the market. These cameras are designed for surveillance, easy to install and can be located at considerable distances. To install an IP camera, simply connect it to an Ethernet router. There is no need for power since the router will provide it via a technology called PoE (Power over Ethernet). Because of its popularity within the surveillance market, there are a wide variety of IP cameras available, from fixed position to PTZ (Pan, Tilt and Zoom), mounted in dome, bullet or hidden cases. You will find whatever type you require by making a search on Internet.

    blank
    Figure 1 - IP Camera 1
    blank
    Figure 2 – IP Camera 2

    How it works

    The IP camera captures the video via a sensor chip and encodes it to an h.264 video streaming format. The video is encapsulated into packets. Connected to the internal Ethernet router, these packets are then accessible by any computer connected to the router (or worldwide if the router is configured accordingly). This allows more than one computer to have access to these packets. The packets are then recognized by a software that decapsulates the video content, generating the video on the computer screen.

    blank
    Figure 3 – IP Cameras audio and video capture

    The pros

    There are a variety of IP cameras available. The video generated is already encoded in h.264 allowing manufacturers to develop many applications for it. It is also easy to install and configure.

    The cons

    IP cameras are designed for surveillance that does not require very high quality. They generate video and audio of a poorer quality than other types of cameras. The cause of their poorer quality comes from the way the signal is encoded. The encoding is created from a small chip installed in the camera.
    Because of the cost benefit, the algorithm used in IP cameras offers a much lower quality video output.
    The audio output of an IP camera is even poorer. The audio connection type in an IP camera is unbalanced. This type of audio connection provides a smaller bandwidth, and the audio cable cannot be longer than 12’. The result is poor audio quality, creating issues such as bad distinction between hearing the letters “S” or “F”. (See more information in section 3.1.)
    Most interview recording installations will bypass these audio issues by connecting the audio directly to the recording computer. But because the video is sent in packets and the audio in real time, it is not possible to perfectly synchronize the two together. The result creates a situation where the lips are not synching with the voice during playback. See Figure 3.
    Because this technology connects to the internal Ethernet router, if there is a breakdown on the network, all the interview rooms will be out of service.
    Finally, because IP cameras are network connected, they are more vulnerable to external hacking.

    USB CAMERAS

    USB cameras are becoming more popular. Like IP cameras, there is a wide choice available from fixed, PTZ, dome, bullet, hidden and more. This type of camera is designed to connect directly to your computer via a USB port. It is widely used for teleconferencing, classroom recording or other applications such as FaceTime or Skype.

    blank
    Figure 4 – USB Pine Hole Camera
    blank
    Figure 6 - PTZ USB Camera
    blank
    Figure 7 - Varifocal USB Camera

    The pros

    USB cameras are widely available. The quality of the video is acceptable for interview recording. The limitation of the 15’ cable is overcome by using a USB extension module, which will provide up to 330’ between the camera and the computer. Because USB technology utilizes the real time transmission of video, it is possible to connect the audio directly to the computer and get full synchronization between video and audio. This type of camera can be used for either fixed or portable interview recording technology.

    The cons

    The weakness of USB cameras comes from the fact that the encoding occurs in the computer. This means greater utilization of the CPU. Depending on the computer, the number of simultaneous recordings can be limited to six. The USB technology happens to be less stable than the HD-SDI technology. A disconnection and reconnection of the USB cable is required to stop and subsequently restart the recording application.

    HD-SDI cameras

    HD-SDI stands for High-Definition – Serial Digital Interface. This technology was developed and still being used by television stations today. The SMPTE (Society of Motion Picture and Television Engineers) created this format for the highest possible quality of video and audio required by broadcasters. This technology provides a stunning result when encoded in h.264 format. To obtain such an outcome, the video is encoded using hardware encoders installed in the computer. The hardware encoder uses the foremost algorithm to provide the highest quality output that is ideal for law enforcement purposes. Because fewer applications exist outside of the broadcast industry, the range of HD-SDI cameras are more limited. There is a choice between fixed bullet, fixed dome, and PTZ (Pan, Tilt and Zoom) dome. Therefore, during interview recording where hidden cameras are not required, these options are more than suitable.

    blank
    Figure 9 - HD-SDI Multifocal Camera
    blank
    Figure 8 - HD-SDI PTZ Camera

    The pros

    This is the best technology for interview recording. HD-SDI technology provides the highest audio and video quality and offers excellent stability. There is perfect synchronization between audio and video. HD-SDI technology can record monitor screens. The connection of the audio is balanced audio that provides the highest bandwidth and the clearest sound quality.

    The cons

    Because of the hardware encoder card, this solution is more expensive and the varieties of cameras available are limited.

    Lenses

    The choice of lenses is important. We sometimes consider the quality of a lens by its capacity to zoom, but this is not so in an Interview Room application. Specific to interview rooms, the wide-angle capacity of the lens is more important than how close it can zoom onto an object. Subsequently, there is no requirement to zoom on an object that is only 1” in size.
    It is important that within the interview room there is one camera that covers the whole space. This is to ensure that the subject cannot claim to be threatened by an officer, whilst outside the field of view of the camera.
    It is also useful to have another camera that can zoom closer on the subject, and have the ability to record body language, facial expression and reactions.
    Finally, if it could be a benefit to be able to record smaller objects such as a phone or documents.
    When looking at camera specifications, it is useful to examine the optical zoom capability of the camera. This specification will determine how close it can get to an object and its width of the coverage.

    There are many parameters to consider in determining the angle that the camera will cover. A rule of thumb is to multiply the distance to the object in meters by 4.8, then divide by the width yourequire. The result will provide the focal lens parameter needed in mm.

    formula

    Example:

    The room measures 3 meters by 3 meters.

    In order to record the whole space, you will need a lens that covers 90 degrees, if it’s installed on a corner. The focal lens calculation shows a horizontal coverage of 4.24 meters, at a distance of 2.12 meters from the camera.

    By using this formula in Figure 10, a lens with a focal distance of less than 2.4 mm is required. The less the focal lens, the wider the coverage.

    blank
    Figure 10 – Camera wide-angle

    As previously discussed, it is also important to have a second camera that can zoom closer in on the subject.

    In the 3 meters by 3 meters interview room, to capture both the interviewee and the interviewer, will require a camera that has a focal lens of7.2mm. See Figure 11.

    blank
    Figure 11 - Camera covering the table

    Finally, for recording smaller objects such as a smart phone, a camera that has a focal lens of 96 mm is required. See Figure 13.

    blank
    Figure 13 - Camera recording a smart phone

    To record the interviewee’s facial reactions, a camera lens with a focal distance of 14.4 mm is required. See Figure 12.

    blank
    Figure 12 - Camera covering the interview

    To summarize, in an interview room, obtaining two cameras is the minimum requirement. One fixed with a focal lens of 2.4 mm installed in the corner of the room, and another on the wall that has a 20X focal lens varying between 4mm and 120mm.
    Finding cameras with these exact specifications can be difficult, but one can get close enough. For example, for the corner camera, one with a focal lens of 2.8 mm will work. It is not ideal, but it will suffice.

    Question

    What are Authentication and Audit Trails?

    Answer

    Authentication verifies user credentials, like passwords, smart cards, or biometrics to grant authorized access while employing safeguards against unauthorized access to ensure security and data integrity.

    An audit trail, or log, keeps chronological records of system activities, documenting user actions, data changes, and access attempts.

    The primary purposes for authentication and audit trails are the following:

    Authentication: Identity Verification

    Ensures that users are who they claim to be, which supports the prevention of unauthorized access and protects sensitive information.

    Authentication: Access Control and Security

    Safeguards data, systems, and resources from unauthorized access and security breaches by confirming user identity, which ensures proper access levels within a system.

    Audit Trail: Accountability

    Provides a means of attributing actions and activities to specific individuals, which increases accountability for their actions within an information system.

    Audit Trail: Compliance and Governance

    Helps organizations demonstrate compliance with regulatory requirements, industry standards, and internal policies by providing a record of activities and events.

    Audit Trail: Problem Solving and Forensic Analysis

    Assists with identifying issues, understanding the cause of events, and resolving problems. They’re crucial for forensic analysis which allows for better investigation of security incidents and detection of potential vulnerabilities.

    Audit Trail: Monitoring and Detection

    Allows organizations to monitor their systems to detect and respond to suspicious activities, anomalies, or policy violations in a timely manner.

    9 Tips for Finding the Perfect Interview Recording System for Your Police Department

    Being a company with over 20 years of experience building interview room systems and consulting for tons of police departments, we’ve gained a lot of valuable knowledge on the steps police departments should take when considering an interview room system.

    blank

    We want to help you! No matter what system you end up with, you should feel empowered to make the correct choice. You don’t need a degree from MIT in order to have an understanding of the technology that can help (or hurt) the quality of your interview recordings.

    Here are some tips we’ve compiled for you to make an informed decision on the best interview recording system for your police department.

    1. Educate yourself on the differences and pros and cons of IP, USB and HD-SDI cameras.

    The majority of interview recording systems on the market today are compatible with IP cameras. However, this has proven to cause issues with audio clarity and synchronization with the video. It’s important to have an acute awareness of your options so you know what to anticipate once you choose your preferred cameras.

    2. Don’t skimp on the details. The more information you provide to your vendors, the more tailored the proposed solution will be.

    We recommend you send the following information to the vendor you’re considering:

    • Images of your interview room(s) and control rooms with square footage (this will give the vendor an idea of the current scope of your interview room), the placement of your furniture, current issues you’re experiencing that’s affecting the feel in the room, sound proofing, etc. They can then propose some solutions to solve your issues.
    • The distance between the interview room(s) and the control room. This will help the vendor figure out the installation logistics and cable length requirements.
    • The vendor/brand you used for your current system and why it’s not working for you. Is it complicated? Is it missing crucial features? It is time consuming to start, stop and export interviews? Be as specific as possible to ensure you get a demo that is tailored to how the software you’re considering can provide solutions for your issues.

    3. Decide what factors are most important to you when choosing the recording software.

    For example:

    • Do you prefer a picture-in-picture camera layout or side by side?
    • Would you like to record a phone, tablet, monitor, lie detector, or another device? Does your supplier offer a system that has the capacity to record these clearly?
    • Will you be sharing your recordings with individuals outside of your police department? If you will, you want to make sure that the software you’re considering doesn’t require a software download to replay recordings on individual’s devices external from your department.

    4. Check the warranty!

    We can’t stress this enough. You want a system with a long-span or lifetime warranty. The day after the warranty is expired, you are in charge of fixing hardware and software issues. Most police departments end up having to complete the search for a new system all over again or put up with an outdated system with broken parts until they have the budget for a new one. Don’t let your police department end up in this predicament.

    5. Decide who you want to install the system.

    Do you have an IT manager? Would you prefer the vendor install the system themselves? You may be saving costs by having an internal employee install the system but, if issues should arise, you should ensure you have a plan for remote assistance from the vendor.

    6. Attend the demo and, if possible, try the software before you buy it.

    It should be easy to use and all of your coworkers should feel comfortable and satisfied with it once they try it.

    7. Be disaster-proof.

    Don’t forget to invest in a backup battery! If power issues should arise, you don’t want your entire system to be down and lose crucial recordings. Make sure you factor this into your quote request. In addition, it may be smart to invest in several computers to operate the software and media library. Relying on one device may cause a system overload and should the computer experience technical issues or shut down, all of your interview room systems will be impacted.

    8. Decide whether you want a media library and educate yourself on how on-premise and cloud-based storage works.

    Cloud storage gets a bad wrap for being “less secure”, however, this isn’t so. There’s no right or wrong way to handle your storage, it’s about the needs of your department.

    9. Be transparent.

    So you’ve gotten all of your quotes sitting out in front of you and your favorite vendor’s quote is higher than your budget! What do you do? Our recommendation: don’t settle for less. Go back to your preferred vendor and let them know what’s out of your budget. They just may be able to work with you on getting you your dream system for a lower cost.


    Seems like a lot, huh? We know! That’s why our CEO, Claude Turcotte used his audio/visual and broadcasting experience to write a guide that includes all of the information you need to know in order to make an informed decision for your police department.

    Tech Tip Tuesday – How to Limit Ventilation System Noise in Recordings

    MaestroVision’s Tech Tip Tuesday! Where broadcast experts answer your commonly asked A/V questions!

    If you have an A/V question you’d like us to answer, send it to info@maestrovision.com and it might be answered in a future video!

    QUESTION: How can I remove ventilation system noise from recordings?

    ANSWER: Unfortunately, there is no magic solution once it’s already recorded… Noise attenuation needs to be considered at the time of recording. Ventilation system noise is mostly composed of specific frequencies. The trick is to use an audio equalizer to attenuate the frequencies derived from the ventilation system.

    Step 1: Make sure the ventilation system is turned on in the interview room
    Step 2: Put your headphones on
    Step 3: Increase your recording system’s volume to the maximum
    Step 4: Adjust the frequency bands starting with the lowest band until you achieve maximum attenuation of the ventilation system sounds

    There is no standard solution. Simply adjust the different frequency bands until you achieve maximum noise attenuation in the interview room.
