CMR-UPS (uninterrupted power supply) is a high-performance back-up power solution. It solves the problem of high and low voltage spikes and surges by filtering power irregularities and enhancing power source efficiency. It protects from over-voltage, over-current, overload, over-temperature, short circuit and reverse polarity. 

The UPS also provides HDVR system with back-up power if source is suddenly lost or shut down allowing system to gracefully shut down without corrupting video files that could result in loss of valuable footage.
