Meta M23 HF volumetric sensor

The hyper frequency module is a volumetric sensor capable of detecting attempts to enter the area it covers using radio waves. It is not affected by air currents caused by leaving a window open and is a particularly good choice for protecting cabriolets or vehicles with a heater. The module also has the option of extending its coverage by fitting two modules inside the vehicle without causing any interference between them. It's possible to use hyper frequency module in the same room with US volumetric sensors.
Meta M23 high frequency module is suitbale for any Meta caralarm.
