This product is easy to install. You only need to stick the main unit on the door frame and the auxiliary unit on the door or two windows.
The arrow of the auxiliary unit should be aligned with the mark on the side of the main unit.
When someone illegally opens a door or window (the separation between the main and secondary parts exceeds 10mm), the alarm will sound >90db to warn the intruder to leave. When you want to open doors or windows yourself, you can control them with switches.

The alarm is installed on the door or window. If a thief wants to open the door or window, the alarm will sound immediay.
Just turn off the switch when not in use. The alarm uses magnetic induction control technology, which has a long service life and is simple and convenient to install.
It is pasted with self-adhesive adhesive and does not require screw installation. It can be used by pasting it directly!
No damage to household items! (It can also be installed in the computer case of an Internet cafe to prevent computer hardware from being stolen)

When the switch is turned on, a loud alarm will sound if the door or window is opened.
