Rugged Waterproof Design
The PR-104 is rated IP67. IP67 means the device is completely dust tight and can be submerged in 3 feet of water with no harmful effects. In addition, it survives drops from 9.8’ (3 m).
A fully charged battery will allow for 24 hours of standby time. Video is activated by the officer with the single push of a button. Record time is 8 Hours.

The PR-104 produces a 16:9 image and has a 71° video capture angle. This angle is achieved without any noticeable distortion in the image. The lapel camera has an even wider field of view at 100° capture angle allows for catching the entire scene even when the officer is operating in close proximity to target.
On the rear is a 2” (measured diagonally) LCD display. This allows the officer to review video immediately. In normal operation the LCD screen is OFF to extend battery life. The PR104 can be configured to display the devices unique serial number, officer ID, day, hour, minute and second. This ensures there is an accurate record of which device captured the video and at what time.

The PR-104 utilizes MP4 (H.264 – MEPG10 PART 4) video compression. This is the same compression technology that is used in Blu-Ray Disks. This compression scheme allows for comparatively small video files while still maintaining excellent video quality, even when recording high definition video. When the video is extracted from the PR104, it can be played back on any Windows computer from Windows VISTA to Windows 10 by using the Windows Media Player that ships with the operating system. There is no need to distribute a special video viewer or video codec’s to users PC’s, thus reducing the work load on the departments IT staff.
The PR-104 has an integrated 2” color LCD display. The officer in the field can review video on the LCD.
The PR-104 can also be integrated with a two way radios. Officers that carry a 2 way radio may have a lapel worn microphone. In order to reduce equipment clutter on the officer, the PR104 can be interfaced to the two way radio. The push to talk and microphone functionality in the PR-104 can replace the 2 way radio’s microphone.
