David, Thank you for your question. This camera is an analog camera that is designed to be plugged in via coaxial cable to an analog camera recorder. As such, it does not have capabilities for recording video in and of itself. It just sends a constant video stream to a recorder.
We do have a nanny style camera that can record based on motion onto a built-in SD card, found here: platinumcctv.com/motion-detector-sd-nanny-camera
Please let us know if we can help further.
