Protect 204 M80204 is a 4-channel mobile DVR designed for use in coaches, city buses, minibuses, street cars / trams, subway, corporate vehicles, tractor-trailer trucks / TIR tracks, patrol cars, prisoner vans, ambulances, 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. This function is maintained for 8 seconds after turning off the ignition. The power circuit is protected by 10 A fuse.
Protect 204 has 4 sockets to plug in adapters terminated with standard connectors for security cameras: BNC (video), RCA (audio), 2.1/5.5 mm jack (12 VDC). They enable the installer to quickly and easily connect the cameras and microphones, including power supply provided directly from the DVR. The M80204 DVR can simultaneously monitor and record images from 4 cameras, each with D1 resolution at 25 fps.
The use of 2 TB 2.5-inch HDD as the storage media allows for continuous recording of the surveillance data for nearly a month. The HDD is mounted in a compartment protected by a cap lockable by key - by opening the cap the the user automatically turns off the DVR, which guarantees safe exchange of the storage media. Ethernet interface (RJ-45) allows for access to the DVR via network connection, using Internet Explorer.
The GPS antenna has a magnet and double-sided adhesive tape for easy attachment to a surface inside the vehicle. It is recommended to install it near a window to ensure the best possible signal level. Long (5-meter) and thin antenna cable can be run under the lining. GPS data is used to record the route and speed. The information can be retrieved using the application supplied with the DVR. The software, in addition to generating the map of a journey, can play back the video recorded from the cameras, create charts of acceleration and find the moments of activation of alarm inputs. If necessary, the application enables the user to export any portion of the recordings in AVI format.
Alarm inputs can monitor any systems of the vehicle which provide electrical signals coming from the sensors and control devices, e.g. fuel filler opening, opening/closing doors, fastening seat belts, opening cargo space, pressing the brake pedal, switching on turn signal etc.
The DVR is managed with the use of the included IR remote control. The graphical menu is available via analog video output and can be displayed on a suitable video monitor.
