2.4GHZ DIGITAL ENCRYPTED W/ BUILT-IN DVR QUESTIONS

How does digital motion detection recording work?

Digital motion detection is a feature for many self recording all-in-one cameras, DVRs and recording software. It senses video pixel movement to trigger the recording, thus saving memory and time when you review the video. Therefore, you only need opening for the lens of the camera to detect motion. When motion is no longer detected for a certain time (programmable) it will stop to record and wait for the next trigger. However, it will not save the power, if battery powered, since both the camera & DVR has to be 'ON' in order to detect motion.
