How to choose suitable intrusion sensor for home improvement?

Choosing correct sensors for your alarm system is very important before the installation of alarm system. Nowadays security companies are offering wide range of sensors (detectors) for different applications. In order to protect your property from intrusion, fire, gas leak, flood and more, you’d better to get full knowledge on difference between these sensors.

Sensors can be classified on accordance with three major functions, they are intrusion sensor, fire sensor, event sensor. Intrusion detection is the major role for the alarm system, thus it’s very important to choose correct sensor which is suitable for your installation environment and meet your requirements. Currently, PIR motion sensor, perimeter beam sensor, reed switch (magnetic contact) are three basic and essential intrusion sensor.

PIR motion sensor, PIR is an abbreviation of passive infrared. PIR motion sensor adopting the passive infrared detection technology, it is sensitive to the relection of infrared ray energy changes which is caused by human movement body. Typically, PIR motion sensor with wide angle detection, looks to protection space, detection range reach up to 30-40ft. PIR motion sensor is suitable for large space protection. Accurate detection is very important for every sensor. In order to solve the false alarm caused by environment, some motion sensor adopting temperature change compensation technology, even some manufacturers launched dual-tech motion sensor into market. Dual-tech motion sensor means integration both microwave and PIR sensors together for more accurate movement detection, thus to reduce false alarm rate. Something you need to note; traditional PIR motion sensor is sensitive to rats, pets, if your family with dogs or cats, you need to choose pet-imune or pet-friendly motion sensor. By the way, traditional PIR motion sensor is only suitable for indoor applications. If you want to install the motion sensor outside, you need to choose outdoor motion sensor.

Reed switch or magnetic contact is the widely used intrusion detection system, it’s most reliable intrusion detection sensor, ideal for sensing open and close of any doors/windows even safe box. More over, a wired magnetic contact sensor is very cost-effective, it’s the cheapest intrusion sensor among other detection sensors. There are two types of reed switch; recessed magnetic contact and adhesive magnetic contact. Recessed magnetic contact is suitable for wooden doors/windows for recessed installation, and adhesive magnetic contact is more convenient for installation.

Perimeter beam sensor adopting the active infrared detection technology, it’s point to point intrusion detection. The beam sensor comes as a pair, consisting of active infrared beam transmitter and active infrared beam receiver. The advantage of perimeter beam sensor is its ability to protecting long range space and create an invisible fence around your property for up to 900ft. Majority of beam sensors are working both indoors and outdoors, with perimeter beam sensor, you can setup perimeter driveway system or perimeter security system to protect your premises from un-wanted people, or detecting un-authorized entries.

Of course, there are other types of intrusion sensors, such as glass break sensor which with function to detect glass smash sound, it’s an expensive but effective intrusion detection sensor, which is suitable for residential and retail shops. For the installation of glass break sensor, you should not install them directly to the glass windows, the correct installation method is installing glass break sensor to the place where near to windows.

Unifore security is one of pioneer security equipment manufacturer. The company providing complete wide range of intrusion detection sensors with high performance and reliability at affordable price. The company also is offering complete security solution to residential and commercial business from intrusion alarm system to video surveillance system. Recently, this company offers latest design 4 channel IP camera system with start price from US$214, it’s available from here: (http://www.hkvstar.com/item/4-channel-hd-poe-nvr-kit-home-camera-system.html)
