video before a motion event. This allows you to see the entire event instead of starting
when motion detection is triggered.
The system detects motion in two ways. The cameras have a built-in Passive InfraRed
(PIR) sensor that tracks heat from body movements to detect movement up to a maximum
range of 16 feet (4.9 meters). PIR motion detection is extremely accurate at detecting
movements from people and animals, but the accuracy decreases in extremely hot envi-
ronments approaching or exceeding human body temperature (98.6°F / 37°C).
PIR Motion Detection
A camera detects heat movements (for example: body heat, running car, and so on), and
triggers the system to record.
The system also uses video motion detection, which looks for changes in video images
(frames) to detect motion. Video motion detection allows for motion detection beyond the
range of the PIR sensors and in extreme temperatures. Video motion detection is fairly ac-
curate, but may trigger recording from changes in light or moving trees, leaves, and so on.
You can set the sensitivity of video motion detection depending on your preferences. See
9.4.3 Configuring Video Motion Detection, page 27
Video Motion Detection
The system detects movement in the image and triggers recording.
Both PIR and video motion detection are enabled by default for enhanced accuracy.
