The Monnit Power-over-Ethernet (PoE) Dry Contact Sensor detects when there is contact between the two wired endpoints. It can easily be integrated into existing switches or contact plates. When the sensor detects contact between the two endpoints, it will immediately transmit the data to iMonnit, allowing the user to immediately receive an SMS text or email alert. The sensor can be configured to detect both closed and open loops alerting if contact is made or broken.
The Power-over-Ethernet (PoE) Sensor products measure various conditions (environmental, power, access). All devices come with flexible settings — including notifications, alerts, reports, and maps — can be customized in the iMonnit online sensor management interface.
No PoE infrastructure in your building? Plug the PoE•X Sensors into your Ethernet network and then power the sensors with the optional AC power supply.
