The Protect 804 M80804 is a 4-channel mobile DVR designed for use in coaches, city buses, minibuses, street cars/trams, subway, corporate vehicles, tractor-trailer trucks/TIR trucks, patrol cars, prisoner vans, ambulances or military vehicles. It has been specifically designed to provide increased resistance to vibration and shock.
The DVR is designed to be mounted inside the cab of a vehicle, e.g. under the seat, in a glove compartment etc. The power cables have to be connected to the battery and ignition switch (similar to radio), so that the device automatically begins video and audio recording simultaneously with turning on the ignition. The power circuit is protected by 5 A fuse which protects against excessive current drawing and burning of the wiring in the event of a fault. By default, the recorder runs until the power supply is turned off with the ignition key, unless the delayed turn off function (running for a specified time after switching off) or a schedule function is active. The recorder has also its own power backup and runs for about 10 seconds more to safely save all data.

The Protect 804 has 4 video inputs with M12 connectors to quickly and securely connect the video signal and power supply to cameras directly from the DVR. The DVR can record 4 channels simultaneously at 15 fps with the 1080p resolution, and 25 fps at 720p or below. The 15 fps is sufficient for typical applications involving monitoring of the space around the vehicle. The video quality is sufficient to easily recognize the traffic situation, the behavior of people, and even faces, or license plate numbers. The AHD, HD-TVI, HD-TVI and CVBS signals are supported. The signal type has to be set in the DVR (default setting is AHD 1080p).
The DVR has 2 video outputs: VGA and CVBS with the M12 connector.
A GPS antenna is included. When connected, the GPS module turns on automatically and details of the speed and device position are included in the video. At the same time, data from acceleration sensors,which read the data in three axes (X, Y and Z), is always saved.
Video and audio signals from the connected cameras are archived on SD cards. This allows an easy and quick access to the saved data, just by removing a card from the DVR and reading it with a PC/laptop. Then, the recordings can be played back using the included software. The recordings are stored along with the GPS, acceleration and alarm input data in their respective device formats. In addition to searching and playing recordings from cameras, the software enables the use of the additional DVR capabilities including generating a graph of the alarm input activation on a timeline or vehicle position based on the saved GPS coordinates.
The DVR supports H.265 video compression which, compared to its predecessor (H.264), reduces by half the data stream and the demand for disk space. Thanks to that, the capacity of data carriers can be reduced by half, or twice as long recordings can be stored.
The alarm inputs can monitor the vehicle devices plugged into the electrical system. These may include shifting into the reverse, opening the fuel filler door, door closing, seat belt fastening, cargo area opening, brake pressing, indicting etc. Activation of an input can be linked to an alarm action, e.g. the shifting into reverse can display lines on the camera image showing the distance, or switching the image preview to a specific camera.
The DVR is controlled either with the included IR remote control, or a mouse connected to the USB port. The graphical menu is displayed via a VGA video output to which a monitor can be connected.
