With a single quick-disconnect, the DSR can provide power, control and video to cameras for body-worn applications that require extreme portability. The DSR has an integrated hard disk drive and a field-replaceable lithium- polymer battery. It offers pre-event recording and embedded time/date/ serial number information in the video to support chain-of-evidence requirements.
