The camera is supported by high-quality
PIR sensor with the sensitivity up to 10m.
Considering the
PIR sensors as targets to be viewed by the MM sensors does not work because a
PIR sensor can be well within the camera's sense range but out of the
PIR sensor's FoV as demonstrated in Figure 1(d).
A
PIR sensor is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view.
The sound waves & bright red light activate when an animal enters the
PIR sensor range which can be easily adjusted using the sensitivity dial up to a maximum of 500sq ft.
Most of the time (more than 90%) the system, except for the
PIR sensor, resides in a/its sleep state until alerted by an event.

PIR sensor (PS20.99, Screwfix), this is a stunning contemporary take on a traditional lantern light.
PRODUCT OF THE WEEK If you're thinking of cracking open the barbecue for some alfresco entertaining, the good-value Antler brushed stainless steel wall light with PIR (PS31.49, Screwfix) will light up your bangers and burgers in style Also available in black and without the
PIR sensor (PS20.99, Screwfix), this is a stunning contemporary take on a traditional lantern light.
As mentioned earlier, one other difference between two setups is usage of
PIR sensor in dynamic setup and WD in controlled setup.
The
PIR sensor means the light comes on when you're fumbling for your keys in the dark as you approach your front door.
