Nowadays, for most security / surveillance purposes, traditional analogue storage equipment is no longer adequate to fulfill and meet the substantial needs of current application conditions. Consequently, leading to ineffective monitoring: when an event occurs, those devices, unfortunately, cannot provide the necessary important clues. As a result, the police and investigative agencies are desperately looking for a way to improve this inconvenience by employing more effective tools in order to protect people's lives and safety.

Mobile video recorder DM48 assists the police by timely collecting evidence and avoiding any delays in the investigation. Furthermore, when events occur, images of offender’s license plate data will be sent to the control centre immediately and automatically through global network systems and positioning systems. When the control centre receives a warning signal, a timely response can be immediately sent out to the authorities concerned so as to give effective support and provide crime information and the location of vehicles.

The Ai-DM48 mobile DVR supports upto 4 channels of recording and PTZ control via RS-485 to the cameras. Two of the 4 channels are selectable for Audio and Video synchronisation in recording and playback. The device supports an external connection to a DPS device for navigation. The main functions are power delay out to avoid burnout by transient voltage surges--up to 30A current as buffer, backup on SD card is easy to use and avoids backup loss caused by a severe knock, H.264 baseline profile video compression and decompression for greater recording capacity and best configurable video quality.
