Model 4011 is a compact digital video recorder (DVR) designed for embedded OEM applications. It records audio and video (A/V) to USB storage media and can capture JPEG images on-the-fly without interrupting A/V recording. The A/V outputs allow live video, recorded A/V or JPEG snapshots to be displayed on an external monitor. Date and time are maintained by a real-time clock with battery backup. To implement a complete DVR simply connect power, your own custom keypad and a USB storage device.
