The motion detectors type curtain are ideal for perimeter coverage of your home, as they create an invisible safety net of several meters around your home (depending on the scope that has each detector) and detect any human movement attending the day within the protected region.
A very important advantage of providing us with the probe needles is the fact that every aspiring effort invasion prevented early as informed about the intrusion attempt as the would-be robber is still out of the house. Unlike alarm systems, which do not include perimeter protection and that because the motion detectors are located inside the house, informed about the invasion when the perpetrator is in the house.
