Netvox R311A – LoRaWAN Door/Window Contact Sensor

Netvox’s wireless door/window contact sensor utilises a magnetic switch to detect when a door or window is opened.

This LoRaWAN door sensor can be added to your existing LoRaWAN security network. It is ideal for areas where access needs to be monitored.

This wireless sensor sends an alert message to a centralised monitoring system via the LoRaWAN protocol when a window or door is opened.

LoRaWAN door contact sensors are the future of smart security. These devices can be used for commercial and residential properties to monitor access. They can be used to alert property owners to an unlocked door or window in a restricted area. This can be particularly useful when monitoring IT server (clean) rooms, freezers or temperature controlled areas and cargo bays.

We can supply third-party online wireless sensor monitoring and notification system to view data and set alerts via SMS text and email.
