What is the Police’s Body Camera & Speaker?

In today’s technologically advanced smartphone era, almost anyone can record and share live video of an incident in real time. The use of body-worn cameras by on-duty police officers during incidents has been the subject of intense debate. The practice of using police body-worn cameras is still in the initial evaluation and research phase. However, such devices are quickly becoming standard equipment in police departments across the United States

The camera and speaker are miniature portable devices that can be easily mounted on sunglasses, clipped to a hat or helmet, or hung from a collar or uniform lapel. The bottom of the recording device is attached to the officer’s uniform with a wire, hidden in a pocket

Benefits of Police Body Cameras and Speakers

The following is a list of benefits for both police officers and citizens:

Recording interactions with residents may reduce complaints about police behavior and unnecessary use of force because there is a record of their interactions that everyone can see. Police and citizens may be more restrained because they know the cameras are capturing their words and actions.

The use of cameras while on duty can provide conclusive video evidence of decisions made by officers in high-intensity situations. The footage is valuable in piecing together exactly what happened.

Video captured by body cameras helps protect police officers and citizens from false accusations, misconduct allegations or abuse.

Increases transparency and accountability for officers.

May help prevent and de-escalate confrontational situations between police and civilians.

May help provide valuable evidence to obtain accurate witness and victim statements.

Captured video footage can provide incontrovertible evidence of circumstances and help expedite court proceedings. It may reduce court costs. For example, it may help increase pretrial plea bargaining or possibly increase conviction rates.

What is Digital Mobile Radio (DMR) Walkie Talkie Function Works For Public Safety?

DMR stands for Digital Mobile Radio and is the international standard for two-way radios.The DMR standard allows devices developed by different manufacturers to operate together on the same network, performing all the functions defined in the standard.

DMR walkie-talkie radios have automatic digital mixed mode operation. dmr radio users do not need to switch to analogue operation mode to respond. The handheld radio is specifically designed for mission critical users. It automatically recognises the call signal and sends it in the same mode in which it was received.

The aim of the DMR standard is to create a digital radio system that is less complex and less costly, still allowing equipment from different manufacturers to work together and allowing users to shop around rather than being locked into a private system that will be expensive to replace and maintain.

The European Telecommunications Standards Institute (ETSI) is responsible for the creation and maintenance of the DMR standard. The standard was first approved in 2005 and has been updated and revised several times since then, most recently in November 2018.

How does a DMR radio work?
DMR is a TDMA mode (Time Division Multiple Access), which means it allows multiple users to share the same frequency channel by dividing the signal into different time slots. Each frequency has either slot 1 or slot 2 and each slot can be used by different users.

Do all DMR devices work together?
Yes, no. Basic functions such as voice messages are always possible. You can even use functions that are not part of the defined DMR standard if the manufacturer of choice has performed interoperability testing.

Before deciding which new product to buy, it is a good idea to check the features you currently use to see if they are unique to the current device.

What frequencies do DMR devices operate on?
Digital Mobile Radios operate on frequencies between 30 MHz (megahertz) and 1000 MHz, or 1 MHz (gigahertz). This frequency range is divided into two categories.

Very High Frequency (VHF) – the range between 30 MHz and 300 MHz.
Ultra High Frequency (UHF) – 300MHz ~ 1ghz.

Most DMR equipment falls into the 136 – 174 MHz and 403 – 527 MHz parts of the spectrum. Each country has its own organisation that issues licences for different frequencies.

Some DMR frequencies are designated as unlicensed (for DMR Tier I), while other frequencies require a licence to use.

        There are a number of contributing factors which can affect the audio performance of your device:

        The most common cause of poor sound quality is water in the microphone or speaker.

        If the handset has been subject to immersion in water then the microphone and speaker may need to dry out to resume normal functionality.

        You, or the other person you are speaking with, maybe in an area of poor signal. Try moving to a different area.

        You may have dirt/debris covering the microphone or speaker. If so, clean your device.
