Range Control (Bits 0-2)
Motion Detection Range Control
Controlled by application
These bits determine the relative range of motion detection. Larger values decrease the range of
detection. Typical values used for Range are dependant on the lens and pyroelectric sensor being used.
Range is also dependent on target size, speed, and relative temperature. For example, a range control
setting that rejects one target of a particular size at a given distance does not guarantee that a larger
target will be rejected at the same distance.
