The magnetic traps work perfectly. They were added as a supplement to an alarm kit that the technician installed in an apartment in Belgrade. A simple magnetic trap that works very well, you don't need to ask silly questions about how many meters it covers. It is for a simple apartment or maisonette, all of you who have a tower will have to dig deep into your pockets to get something branded so that the RF signal can pass through the walls of your tower. The battery is small but lasts quite a long time, unless you put the magnetic contact on a bar door that opens and closes all the time, in which case you'll need a new battery every night before closing.
Attention to those of you with towers who ask questions just to emphasize how big your house is. Of course, your questions will be answered, but we'll pretend we didn't notice. Only love.
