Proximity Detectors
Devices for detecting proximity or presence are options with KIS.
We provide three basic one:
- Mat detectors (from Larco). The best and most reliable solution. Has a serial interface and besides being clearly more reliable, it also costs more ($400)
- Infrared detectors. See separate page on them. Cost is approximately $150
- Ultrasonic. Work very sporadically. We do not recommend them.
