This virtually invisible window contact can be installed in the apartment / house near the window so that it is not visible from the outside and barely visible from the inside. A flat magnet is mounted on the bottom of the wing so that the transmitter sends a signal to the control panel when the window is opened.
The BTS transmitter is mounted barely visible under the windowsill using a 33mm magnetic pad.
You do not need to drill through this mounting.
