What is the principle of wireless alarm? Is it suitable for home use?

Wireless alarm is an alarm that uses space electromagnetic waves to detect the transmission of electrical signals. The wireless alarm is unique in the case that some prevention sites are scattered or it is inconvenient to lay transmission lines. In order to realize wireless transmission, a wireless channel transmitter and receiver must be added between the detector and the alarm controller.

Principle:

The alarm system uses SMS and voice function platform of GSM wireless cellular telephone network to complete remote alarm data transmission and control. The system can be deployed according to the mode set by the owner. When the detector detects the intrusion signal and sends an alarm signal to the host, the host will send a short message with the alarm address and category to the user's preset mobile phone number after processing, and automatically dial the preset phone number 1-3 for voice alarm and on-site monitoring. In addition, users can defend/withdraw the system by sending short messages remotely.

Suitable for home use.
