Digital Display
Features an 8-frequency conversion digital display, providing clear and concise information about the sensor's status.
Wired Installation
The wired installation of this detector ensures stable and continuous operation, ideal for permanent security setups.
Certified Safety
CE certified, this sensor ensures compliance with international safety standards, giving you peace of mind.
Long Detection Range
With a detection range of 100m, this Meian infrared sensor barrier detector ensures wide coverage for security needs.
Dual-beam Technology
Equipped with dual-beam infrared technology, it offers enhanced accuracy and reliability in detecting intrusions.

Meian Wired Dual-beam Infrared Sensor
Working Principle:
The light emitted by the transmitter directly enters the receiver. When the detected object passes between the transmitter and the receiver to block both beams of light, the detector then sends an alarm signal to the host. Suitable for perimeter defense and alarm systems for fences, yards, farms, etc.
Product Features:
1.Dual-beam Infrared Sensor: Adopts aspherical coated optical lenses and professional DSP chip, strong anti-interference, high levels of anti-RFI / EMI capability.
2.Digital Fuzzy Artificial Intelligence Recognition: Intelligent power emission.
3.Intelligent 8 Frequency Conversion: Anti-interference and anti-false alarms.
4.Digital Display: Shows the bus address, signal strength and operating frequency in real time.
5.Adjustable Optical Axis Angle: 90°left/right, 10°up/down for easy installation.
6.Intelligent Heating Function (optional): The receiver and transmitter have built-in iron-aluminum alloy, which can be connected to a 5V heater (optional). When the ambient temperature is lower than 5℃, the HEAT terminal will output a 5.5V voltage to the heater Power supply can effectively prevent light blocking caused by haze and low temperature.
7.Tamper Function: This product has a tamper switch, which can trigger an alarm when the outer cover is loose under working conditions.


Alarm Principle
The intruder blocks two infrared beams and triggers an alarm


Aspheric Coated Optical Lenses
Improves the infrared emission focusing ability and guarantees the quality of infrared long-distance transmission

8 Frequency Conversion
Set different frequency bands for each pair of Infrared Detector to reduce interference

Digital Display
Dual digital tube display of the bus address, signal strength and operating frequency, easy to install and maintain

Adjustable Optical Axis Angle
Horizontal: 180°(±90°), Vertical): 20°(±10°), convenient to focus in all directions during installation

High Sealing Design
Dust-proof, waterproof, rain and fog-proof, effectively preventing interference caused by the external environment

Pet-proof, Not Easy to False Alarm
Only when two infrared beams are blocked simultaneously will an alarm be triggered, and small animals will not trigger an alarm when only one beam of light is blocked
