Day-to-Day Experience

Installation requires a bit of patience to ensure the transmitter and receiver are perfectly aligned, but once calibrated, the system is highly responsive. Keep in mind that you will need to source a separate power supply, as the unit does not come with one included in the box.

Who Should Buy This?

This is an excellent choice for homeowners looking for a simple, wired sensor to integrate into a DIY security setup for specific windows or gates.
