The benefits associated with a home burglar alarm should be pretty self explanatory. Although these alarm systems come in many different types and styles, the same basic benefits are always there. These systems are designed to deter burglars or intruders from entering your property while simultaneously notifying anyone listening that an intrusion is taking place using lights, sirens, sounds and calls directly to the police in some instances. Different alarm systems will vary in the exact types of protection that they provide you with. Learning how an intruder alarm works will help you best take advantage of this type of protection for your home and family.
There are several different types of alarm detectors that you can utilize to protect your home, and each type of alarm system is going to be unique in some way. The most basic two types of detection devices in alarm systems are motion sensors and perimeter or circuit protection devices. You can combine both to make your home secure, or choose the one that will best meet your needs depending on the type of protection that you are trying to create for your home.
Perimeter detectors are for the exterior of your home, essentially. You attach them to your doors, windows and other entry ways. When the alarm system is armed and one of these doors, windows or other entry ways is open, and the circuit is broken or completed depending on the type of alarm system, then the burglar alarm is going to sound. There are both open circuit and closed circuit systems, with closed circuit systems being ideal for most burglar alarm situations because if an intruder tampers with them, the alarm will sound as well. Open circuits can be tampered with, since the wires can be cut before the circuit is completed by a door or window opening.
Motion sensors work differently, and a burglar alarm using motion detection technology will work inside of your home. The way that this technology works is by shooting out a frequency that crosses the room and bounces back to the motion detector. If the way that the frequency bounces back is suddenly disrupted, the hardware deduces that something is in the room that was not previously there, and sounds the alarm accordingly. Passive infra-red motion sensors are the most common and works by open and close operation whereby the sensor is normally closed until it detects a movement in the area of protection and sends an open signal to the control panel to trigger an alarm. If someone does manage to break into the home, a motion detector will make it obvious very quickly so that the intruder can be swiftly dealt with.
