Door Monitor


Often the ‘status’ (OPEN/CLOSE) of a door, window, gate, or any other object that opens or closes needs to be remotely monitored. Netstream Integrated Solution devices with digital inputs can be paired with a reed switch to create a door sensor, monitoring whether a door is open or closed and sending an alert if necessary. 

Custom duration alerts can be configured. It may not be of much interest if the door is simply opened or closed, but alerts may be needed if a door remains open for too long, particularly if security and/or temperature is a concern. 


What is a reed switch 

A reed switch is an electrical switch operated by a magnetic field. 

In its most basic form, the switch consists of a flexible ferromagnetic metal contacts inside a sealed glass tube. When a magnet is brought Close to the ‘reeds’, the reeds move so that they come into contact, closing the switch. You can often hear a slight click sound when this happens if you hold the switch to your ear.
