The key difference in wireless and hard wired systems is in the way that they communicate. The control panel, sensors, and alarm all communicate through radio signals, while electrical wired connection facilitate the communication of these components on a hardwired system.

Beyond this fundamental difference, the actual methods for detecting intrusion are essentially the same for both. A majority of systems are based on motion detection using Passive Infrared technology (which works by reading the body heat of an intruder), often times combined with magnetic sensors attached to doors or windows that trigger an alarm when they are opened.

Benefits of a wireless burglar alarm

How do they work?

At the most affordable end of the market there are alarms with a basic but highly reliable functionality consisting typically of motion sensors that trigger an alarm and send a pre-recorded alert to a specified phone.

Not all wireless alarms are based on motion sensors. Alarms can be triggered by the detection of the low frequency sound wave created by the pressure change arising from forced entry into a building. Remarkably this system works simply by plugging a single alarm unit (the size of a small radio) into the mains - with no other type of sensor required anywhere else in the building.

Wireless burglar alarms do not have any hard wired connections; instead they are run on batteries. Because of this, the batteries will need to be changed or recharged quite frequently so that the wireless burglar alarm is fully functional. As long as you can remember to change the batteries on your wireless burglar alarm at regular intervals this option would require the least maintenance. Setting a calendar reminder for the same time with your phone or email is a good way to stay on top of maintaining these wireless units. It’s better to change the batteries before they die, rather than go without security.
