The PIR sensor is a good fit if you need a wider triggering area than a beam sensor can provide. It also has the benefit of being single ended no separate transmitter and receiver. When the Scout PIR is used with the Scout CamBox the system offers wireless triggering of the camera. The trigger is incredibly easy to use right out of the box but also offers the flexibility of a USB interface ...

PIR Motion Sensor Tutorial : 8 Steps (with Pictures ...

+

PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens costs only a few cents and can change the breadth, range, sensing pattern, very easily.
