Burglar Alarm Systems: How do They Work?
When searching for a home security system, you'll most likely encounter two types of burglar alarms: Hardwired and Wireless. The two systems do essentially the same things, but how they do this varies.
Hardwired systems:
The more traditional choice, are wired directly through walls. All motion detectors, window and door sensors are wired directly to the central control system. All of the wires are concealed and reporting to one location, there are fewer chances for false alarms or interference with the system.
Wireless systems:
These systems have small transmitters that wirelessly communicate information about doors or windows, and whether they’ve been opened, to the central point of the system. The devices are normally exposed near the protected area, like a window or door area.
When arming or disarming an alarm, each system requires a secured code. If the code is not entered or is improperly entered, an alarm will sound. Sensors in the alarm system detect movements in the house, which will also sound an alarm. The systems send a signal to the central station, emergency personnel are notofied, along with the key holders and alarm company.
