The Model 4011 from Sensoray is a compact digital video recorder designed for inspection systems. It records audio and video to USB storage media and can capture JPEG images without interrupting A/V recording. The outputs allow live video, recorded A/V or JPEG snapshots to be displayed on an external monitor. The date and time are maintained by a real-time clock with battery backup. The board encodes standard NTSC/PAL composite video using efficient H.264 compression. Each of the three overlay generators can position up to 160 text characters anywhere in the video frame. An external USB storage device is required for DVR operation. If desired, a second USB storage device may also be connected, and the unit will simultaneously record to both devices. A common application for this is recording to a removable device while creating an archival copy on a non-removable device.
