I got this for my toddlers bedroom door so I would get woken up in the night if he started wandering. It’s really easy to install, lots of settings. Loud enough to wake me up when his door is opened as I wanted it to, and a large variety of tunes but to be honest the basic one is enough. Good quality.
The unit is really easy to set up and fit to your chosen location.You are able to fix it to the surface with self adhesive stickers or fixing screws supplied.Once a door is opened and the connection separated,the alarm is activated.Works really well and gives you added security.The main receiver plugs in to a socket in your chosen room.
