Shortlisting Digital Video Recorders
When investing in mobile technology one of the most important elements is the Mobile Digital Video Recorder (DVR). It is particularly important for passenger transport that the DVR is designed for the rigours of mobile applications.
In order to withstand prolonged exposure to vibration and shock, mobile DVRs should be encased in a rugged metal chassis and mounted on high quality suspension dampers. The use of rugged multi-pin connectors assures good quality connections even with continuous vibration.
The latest DVRs have the capability to show advertising or passenger information that can even be location specific, such as an advert for a restaurant on the route, providing a possible revenue stream for operators. The use of GPS data can also enable the DVR to be used to track vehicle movements, which is particularly applicable to security applications or where a vehicle must adhere to a set route.
The functionality of DVRs can vary widely, such as the ability to receive input from up to sixteen cameras and the ability to record or transmit sound. The quality of the images can also vary, depending on the record rate. Advanced systems have the capability to link to vehicle systems to record G-forces, the use of accelerator, brakes and indicators.
21st Century has made a comprehensive short list of what is essential when investing in DVR solutions:
- Up to 16 camera inputs (option for IP cameras)
- Up to or over 25 frames per second
- Video compression selectable, Jpeg, Mpeg 4, H.264
- Up to and over 1 terabyte of storage
- High quality vibration dampers
- Options for monitors, audio and communication
