Wireless Security Systems
Wireless home security systems use battery-powered radio transmitters and receivers to connect the various components such as cameras, sensors, area motion detectors, sirens, central controllers, smoke/fire detectors, keypads, and video displays. These types of security systems are usually available at a local hardware store or on the Internet and are often designed.

for do-it-yourself installation. The basic advantages of wireless security
systems are :

➤ Wireless systems are easy to install, They avoid the expensive and time-
consuming task of installing new wires in the walls of existing homes.
➤ Wireless systems enable you to take the components with you when moving to a
new location.
➤ Wireless sensors are designed to transmit a unique identification code to a
controller, The controller learns the identity of each sensor and links it
to an appropriate zone. Each sensor also transmits status information
such as battery voltage, condition of the sensor switch, and other diag-
nostic messages.
➤ Some homeowner-installed wireless security systems can be set up to record a
voice message and to call programmed numbers in the event of an alarm,
This saves the cost of a professional monitoring service.
➤ Wireless sensors, motion detectors, and video cameras can often be installed in
locations that are not accessible for wired equipment.
The basic disadvantages of wireless security systems are
➤ Wireless system design specifications can limit the distance between sen-
sors, cameras, and the central controller.
➤ Wireless systems can be vulnerable to electromagnetic interference
(EMI) in some locations.
➤ They require periodic replacement of batteries.
➤ Most professional builders recommend wireless systems as a last choice.
