Infrared Beam Intrusion Detection System
Detect intrusion instantly with reliable multi-beam infrared technology and low false alarm performance.
- Long-distance Detection up to 300m
- Multi-beam Design Reduces False Alarms
- Stable Performance in Outdoor Environments
Our Infrared Beam Intrusion Detection System Solution
Our digital active infrared beam solution creates an invisible modulated infrared barrier between transmitter and receiver to detect beam blocking in real time and connect alarms, video systems, and third-party security devices for perimeter protection.
- Multi-Beam Detection: 2/3/4-beam options trigger alarms when the required beams are blocked.
- Digital Anti-Interference: Digital pulse, frequency conversion, and filtering reduce sunlight and artificial light disturbance.
- Visual Alignment: LED indicators, digital tube display, or voltage test holes support precise calibration.
- Adjustable Alarm Response: Light-blocking time and detection speed settings adapt to different intrusion speeds.
- Alarm Output: Relay and tamper outputs support alarm signal transmission and device status monitoring.
Core Strengths
Low False Alarm Performance
MCU processing, modulation filtering, and multi-beam redundancy improve detection stability.
Easy Installation
Snap-on structure supports quick wall or column mounting and faster field deployment.
Flexible Perimeter Coverage
30-300m range options and 2/3/4-beam models fit different entrances, walls, and boundary lines.
Durable Outdoor Structure
PC+ABS housing, adjustable optical axis, and optional heating support stable outdoor use.
How It Works
The system emits infrared beams between transmitter and receiver. When beams are blocked, the system detects intrusion and triggers an alarm instantly.
Frequently Asked Questions
What is an infrared beam sensor used for?
An infrared beam sensor is used for perimeter intrusion detection. It triggers an alarm when the infrared beam is blocked by a person, vehicle, or object.
How far can an infrared beam sensor detect?
The detection range depends on the model and application, from short indoor protection to long-distance outdoor security over hundreds of meters.
How do infrared beam sensors reduce false alarms?
Infrared beam sensors reduce false alarms through multi-beam detection, signal modulation, and anti-interference technology for more accurate detection.
Can infrared beam sensors work in rain or fog?
Yes. Outdoor infrared beam sensors work reliably in rain, fog, dust, and other harsh conditions, maintaining stable performance in changing environments.
How do I choose the right beam type and range?
Choose based on installation location, detection distance, environmental conditions, and security level. Higher beam counts are usually better for outdoor use and lower false alarm requirements.
