The products are used for a dual purpose. First of all, intruders will be aware of the fact that the area is being watched, while second, the patrons will be relaxed knowing the house is under solid protection. There are also special “speed domes” that are the units used to provide the device with an opportunity to spin quickly within the protected area.
