Protect 104 M80104 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 M80104 DVR can simultaneously monitor and record images from 4 cameras (2x D1 and 2x CIF, at 25 fps).
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 104 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 use of SD cards as the storage media allows for easy and fast access to the stored data - it is enough to take out the card from the DVR and insert to the card reader in a PC. This is a big advantage - in need of archiving, the user does not have to connect a laptop directly to the DVR in the vehicle. It is easy to copy the data from the card, or simply keep it as the archive (and put into the DVR another card, either a new or formatted one). The SD cards in the slots are 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.
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.
