2-Beam 150 m Infrared Detector — Active IR Anti-Theft Perimeter Alarm

Build a reliable invisible fence for long driveways, fences, rooftops, and compound walls with this 2-beam active infrared detector. A synchronized transmitter/receiver pair creates two parallel IR beams up to 150 m (outdoor) or longer indoor LOS, triggering an alarm the moment both beams are interrupted—reducing false alarms from birds, leaves, or light rain.

Key Features

• Long-Range Protection (150 m Outdoor)
  Dual active IR beams maintain stable links across yards, carparks, and site perimeters; extended ranges indoors.
  
• Dual-Beam AND Logic
  Alarm trips only when both beams are broken, filtering small objects and improving immunity to environmental noise.
  
• Weather-Tough Housing (IP65-class)
  Sealed, UV-resistant covers with anti-fog channels and hooded apertures for rain, dust, and sun protection.
  
• Precise Optical Alignment
  Internal optical scopes/LED indicators and ±10–15° horizontal & vertical adjustment make aiming fast and accurate; alignment tone on many models.
  
• Selectable Response Time
  Adjustable alarm delay (e.g., 50–700 ms) to ignore brief obstructions and reduce nuisance triggers.
  
• Tamper & Fault Outputs
  Cover-open tamper switch and signal-loss fault tie into your panel for maintenance alerts.
  
• Universal Alarm Integration
  NC/NO relay output interfaces with burglary panels, sirens, GSM/4G dialers, access systems, or CCTV for PTZ presets.
  
• Heater/Anti-frost (Optional)
  Low-temp heater kit for winter climates; wide operating temperature range.

Installation Guidance

1. Plan the line-of-sight: Mount transmitter and receiver at the same height (≈0.8–1.2 m for perimeter) on rigid posts or walls.
   
2. Avoid obstructions: Keep branches, banners, and reflective surfaces out of the path; allow for seasonal foliage.
   
3. Power & wire: Feed 12–24 V DC to both heads; run alarm/tamper lines back to your panel.
   
4. Align: Use the built-in scope/LED/buzzer; tweak vertical/horizontal angles for peak signal.
   
5. Set response delay: Choose a value that ignores brief passes but catches intrusions.
   
6. Test: Walk-test at several points; verify panel zones, siren, and notifications.
   

Best Practices

• Use dual-beam towers every corner; stagger heights or add additional beams in high-risk corridors.
  
• For long spans or harsh environments, consider adding sunshades and enabling heater/defog.
  
• Pair with CCTV to auto-call up cameras on alarm.
  
• Perform seasonal checks: clean lenses, trim foliage, re-verify alignment.
