Application diagram of M85006
MDR4204 M85006 is a 4-channel mobile digital video recorder for use in buses, urban buses, vans, corporate vehicles, tracks and various special vehicles: TIR, police and prison vehicles, military vehicles, ambulances. It can be also applied on trains, trams, subway/underground. The device has been specially designed to show increased resistance to vibration and shock. It allows to record 4 video channels and 2 audio channels simultaneously. The user can monitor one channel selected at the moment or all four channels. The DVR cooperates with analog cameras in PAL or NTSC standard. With a portable USB HDD (enclosure included), the user can easily transfer the recordings from the recorder to any desired computer.
Distinguishes features of this model are compact size and ease of operation.

MDR4204 mobile recorder allows to save data in MPEG4 format. As a result, the amount of space occupied by the recordings has been limited, which extends recording time. For example, a 160GB HDD can store recordings for 5 days. The table below illustrates how much disk space is taken by an hour of recording for each of the five standard recording settings.
Parameters of recording
| Quality level | Resolution | Audio stream | Video stream | Disk space consumption |
|---|---|---|---|---|
| Standard 1 | CIF | 64 kbit/s | 512 kbit/s | 246 MB/h |
| Standard 2 | CIF | 64 kbit/s | 1000 kbit/s | 456 MB/h |
