The system contains a host machine, wireless infrared surveillance probes and wireless controllers. The alarm host machine is connected with phone line, and wireless infrared surveillance probes need to be installed in the areas that need be monitored. Control the system on/off by the controller or cell phone/ telephone (when you are not in the house). The siren of the system will alarm, while someone comes into the protected area, at the same time the system dials the pre-fixed alarm telephone number automatically. Even if the host is not in the house, he can know the condition of the house and adopt relative measures in time. The most advantage of the system is that it can be controlled by remote cell phone or telephone. The system is suitable for normal family, offices and so on. The systems can extent to be smoke alarm, gas alarm and door magnetic alarm and so on.
