Wireless Security Systems--What Are They Made Of?
- Control Panel-- No matter what system you choose, it will have a master control panel. People usually choose to locate it somewhere convenient since it controls all the operations of the home security system.
- Sensors & Transmitters--Sensors detect changes in the surrounding environment (such as someone trying to enter the premises) and through the use of transmitters, they then send a wireless signal via radio waves to the control panel where the receiver is housed. Sensors are typically placed at doors and windows.
- Touchpads--Remote touchpads allow users to operate the security system when they are not next to the control panel and are typically installed at convenient places around the house.
- Central Monitoring Receiver--These are often used in conjunction with monitored alarm systems and will be hooked up to the telephone line.
- Sirens--Sirens are often employed for scaring away intruders.
- Lamp Modules--Many people employed light timers as part of a security system; these serve to trick a would-be burglar into thinking someone is at home, thus acting as a deterrent.
