Security Sensor - SSXX
The Security sensor is a magnetic on/off switch for monitoring doors and windows. When the door, or window, opens the input signal is detected by the sensorProbe or securityProbe base unit. Alerts can then be generate to notify you even including images captured from an attached camera to give you instant visual feedback on the situation.
They are active switches that close when one half of the sensor is in close proximity to its mate. When the two sensor pairs are moved apart from each other they open. The base unit senses closure and opening of these switches.
