This is one of the main questions home security professionals are asked each day. A hardwired home security system is installed by having wire run from a main alarm control box to alarm devices that are placed throughout your home such as motion detectors and transmitters.
A wireless alarm system is everything a hardwired alarm system is – minus the wire. Instead of wires being run to each individual wireless alarm device, they work off batteries. Both types of security systems are great choices, choosing between the two usually comes down to whether a wire can be run to the protected area.
