1. Advanced Person/Vehicle Motion Detection can be enabled on a single channel only. General motion detection will still be available on all remaining channels. Accuracy of Person/Vehicle Advanced Motion detection will be influenced by multiple factors, such as the object's distance from the camera, the size of the object, and the height and angle of the camera.
2. HDMI output supports 1080p HD for high definition multi-channel live or recorded video viewing. Image quality and resolution is dependent on the type of camera connected to the DVR, as well as TV/ monitor resolution.
