Can cover larger areas, ideal for outdoor perimeter security
Beam Type:
Single beam or dual beam (depending on model)
Infrared beams for reliable detection with minimal false alarms
Weatherproof: Designed for outdoor use with IP65 or higher weatherproof rating
Mounting: Can be mounted on walls, poles, or other structures for flexible installation
Beam Adjustment: Adjustable beam height and angle for optimal detection coverage
Performance
Detection Method: Detects intrusion based on the interruption of infrared beams
Sensitivity: Adjustable sensitivity to fine-tune detection range and minimize false triggers
Output: Typically provides a NO (Normally Open) or NC (Normally Closed) relay output for integration with alarm systems
Response Time: Fast response time with detection capability in < 0.2 seconds
Operating Frequency:
Multi-frequency technology to prevent interference from other sensors or signals
Automatic frequency hopping in some models to ensure stable operation
Construction and Durability
Housing Material:
ABS plastic or die-cast aluminum for high durability and resistance to external elements
Vandal-resistant and designed to withstand impacts and harsh environments
Temperature Range:
-20°C to +50°C (-4°F to +122°F) for consistent performance in varying climates
Protection:
Surge protection to handle electrical spikes and protect internal components
Tamper-proof design to prevent unauthorized access or manipulation
Power Supply
Power Source:
Typically operates on 12V DC or 24V DC
Low power consumption for energy efficiency
Current Consumption: Typically 30mA - 50mA depending on model
Power Backup: Some models offer optional backup batteries for continued operation during power failure
Advanced Features
Alarm Integration: Direct integration with alarm panels for immediate alert when the beam is interrupted
Anti-False Alarm Technology: Features such as digital signal processing (DSP) or rain/snow rejection algorithms to reduce false alarms from environmental factors
Dual Photodiodes: Some models use dual photodiodes to enhance detection accuracy and reduce sensitivity to environmental changes
Automatic Self-Alignment: Certain models have self-aligning features to ensure perfect beam alignment during installation
