How do DVRs work with motion sensing and cameras?
DVR’s detect motion by looking at the video picture pixels. If the pixels change the DVR sees motion. DVR’s have a “Mask” or over lay for each camera. you can define any part of the picture /video to trigger or not the recording. This allows a camera not to view normally moving objects Like tress or fans. Each camera also has motion sensitivity level setting this controls the amount of pixel cange before the systems triggers the recording of the DVR. All motion sensing is done in the DVR software. the camera has nothing to do with motion sensing it just provides the video to the DVR because of this.
