Most of these systems are 'standalone' solutions, and can operate and record footage without the need for additional equipment. When monitoring vehicles and other mobile property, however, it is not always practicable to install such a system, so often a solution is employed that utilizes a number of CCTV cameras connected to a mobile digital video recorder (MDVR) system.
Applications where mobile surveillance systems can be utilized include in:
Designing a DVR system that is appropriate for mobile use presents some challenges. Foremost, the system needs to be able to cope with the bumps and vibration of constant movement. Further, if employing a HDD to record footage, a sufficient backup system often needs to be put in place to ensure that the HDD does not fail under this constant movement.
Another important consideration, and one that applies to DVR systems more generally, is the quality of footage the MDVR is capable of capturing. As HCSS notes, there are two factors that can affect the overall quality of surveillance footage. One is the quality of the DVR recorder, while the other is the camera resolution.
There is no point in using a high quality DVR system with low resolution CCTV cameras, and by the same token, using high resolution cameras with a poor quality recorder is equally counter-productive.
Optional hardware items these mobile security dvr recorder systems include a GPS that records parameters such as coordinates, speed, heading and altitude in sync with the video. As climate will also play a role in MDVR and HDD reliability, a built in heater for cold regions can be supplied to maintain optimum performance.
