Single beam active infrared sensor for home security

Infrared is kind of invisible electromagnetic radiation between visible light and microwave radiation. Infrared (IR) sensors are used wide range of electronics from a simple IR remote TV controller to top-notch military equipment. In security industry. Infrared technologies with many advantages including low power consumption, invisible light, long range transmission distance and more, equipped with infrared sensor, they can be used to protect your home and business.

Apparently, nowadays users can find various different infrared sensors including passive infrared sensor (PID or PIR) and active infrared sensor (AIR), which are primary products in the security market. I assume you already knew well for the PIR motion sensors, hence we herein introduce the single beam active infrared beam sensor, which can be used to give accurate perimeter protection.

What's active infrared beam sensor?

Beam sensor is reliable detection sensor, which utilizing single or multiply active infrared beams for detection. It can provide extra security protection through forming an invisible barrier around your premises. Therefore, it's ideal sensor for perimeter protection. Typically, traditional beam sensor consists of infrared transmitter and infrared receiver. The space between them is detection range, that can be reach up to 100 - 300 meters. Majority of these sensors adopt weatherproof design which enables them to be installed both inside and outside. NC/NO relay output allows these sensors can work with different systems including alarm system, video surveillance (IP camera and DVRs), as well as access control system.

Active infrared beam sensor is only suitable for long range distance protection. The distance between transmitter and receiver should exceed minimum 5 - 10 meters. Too close or short distance, the active infrared beam sensor may not work properly.

Introduction to single beam infrared sensor

Single beam infrared sensor is one of popular and widely used perimeter protection sensors. Installing each pair at the opposite positions, but in same parallel height. When sensors are powered, there is a infrared area between the transmitter and receiver. When some objects (human, pets, car...etc) pass or cross the infrared region, the alarm will be triggered.

How to connect/use single beam sensor?

Beam sensor can be used in wide range of applications. Without correct wiring or connection, the sensor can't achieve the function as you may expect. Herein we provide some examples, which show how to connect the beam sensor to alarm system, DVRs, IP camera. Please note, if you are not familiar with electronic technology, you'd better ask help from technician.

Connect beam sensor to alarm system

We herein provide hardwired connection only. For wireless active infrared beam sensor, you just need to read manual, then enroll it into alarm panel. Hardwired connection requires four wiress cable (minimum 3 wires cable), two wires for power supply, the other two for hardwired zone connection.

The connection is straightforward, but you need to connect the EOL resistor, when the sensor connects to alarm system. EOL resistor should be connected for proper working and circuit protection. If you connect the active infrared beam sensor to DVRs and other electric devices, you don't need to use the EOL resistor.Furthermore, the IR beam sensors connect to AUX output of alarm panel for power supply. If the alarm system doesn't have AUX output, you can use separate power adapter, check below picture:
