The advantage of a wireless burglar alarm lies predominantly in the installation. Rather than take the time and effort to run yards and yards of cable from the control to every access point in and around the house, a wireless system requires only that the sensors and detectors are put into place. Using radio frequencies, signals are sent from a contact point to the main control panel for instant processing and alert in the event of an intrusion.
Wireless or Hardwired
Hardwired burglar alarms work well in that they are not subject to interference caused by other wireless devices such as cellular phones or computer Wifi networks. That being said, wireless burglar alarms have improved dramatically thanks to new technology, so interference is less of a problem. The best time to install a hardwired system is when the house is being constructed. The exposed structure affords the perfect opportunity to effectively wire up the entire house to your specifications. Wireless systems are desirable in part because most homeowners don't have the luxury of retrofitting their home for a hardwired system.
