Burglar alarms can be an effective way to deter criminals from breaking into a home or business. They can provide security and peace of mind to families and business owners. For individuals considering installing one of these devices, there are many types of burglar alarms to choose from. These systems fall into three different categories of hard wired, wireless and self contained. Hard wired systems require wires to be run from each unit sensor to the main panel. In a wireless system, radio waves are used to communicate between the sensors and panel instead of wires. A self-contained alarm system is a box that contains the alarm, control and sensor within one unit. Home owners and business owners should spend time researching each type of system before choosing the type that best meets their needs.
Of the various types of burglar alarms, one popular option is a system that uses a siren to alert of a robbery. This siren can make an audible noise that will alert the home owner and scare the burglar or act as a silent notification to the alarm monitoring company. These types of system may include flashing strobe lights. The control panel for this type of alarm will allow the owner to arm and disarm the system as needed. It also has the ability to omit certain areas or zones on the property.
Next on the list of types of burglar alarms is a sensor device. These types of systems are capable of tracking movement, noise, smoke, shock, vibration or other similar types of motion. Certain models called PIR, or passive infra red, will even detect movement through heat and are very successful at alerting the owner of a robbery. However, these devices will not be set off due to sunlight, heating systems or property air conditioners.
Magnetic switches are another option to consider. These are easy to install, reliable and not costly to the owner. These types of alarms use magnets that are attached to entry points such as doors and windows. When the door or window is opened and the magnet loses contact, a signal is sent to the control unit that alerts the owner of a burglary. Finally, ultrasonic detectors and microwave detectors are two more types of burglar alarms. An ultrasonic detector works by bouncing high frequency sound waves off of the walls, ceiling, floor, furniture and other fixtures in the room. When a thief disrupts these waves, the alarm is set off. A microwave detector is a similar type of alarm, but it uses radio waves instead of sound waves.
