2-beam 150 metre infrared detector alarm system for home security and business anti-theft protection with wired communication and adjustable 30-150m detection range in black colour
2-Beam Infrared Security Detector with 150 Metre Range for Perimeter Protection

This wired infrared anti-theft alarm system provides straightforward perimeter security through dual-beam infrared technology. Designed for both residential and commercial applications, the detector creates invisible monitoring barriers that extend up to 150 metres between paired units. The system's shooting detection angle creates focused monitoring zones rather than broad sweeping coverage, making it suitable for securing specific entry points, boundaries, or transition areas in warehouses, shopping centres, community spaces, and villa perimeter walls. With wired communication ensuring stable operation without wireless interference concerns, this detector offers consistent security monitoring across various installation scenarios.
Technical Specifications and Installation

The detector operates on 12V power through wired connection, eliminating battery replacement concerns while ensuring continuous operation. Technical parameters include a static current draw of just 3mA during standby, contributing to efficient power consumption. The operating temperature range from -25 to 55 degrees Celsius allows installation in various climates and environments without performance degradation.
Detection Range Adjustment
The adjustable detection distance spans from 30 to 150 metres, providing flexibility for different security scenarios. Shorter ranges increase sensitivity for high-security areas, while maximum distance coverage protects extensive boundaries. This adjustability allows customisation based on specific property layouts, terrain considerations, and security priority zones within the supported applications.
Wired Communication Advantages
Wired communication between detectors eliminates wireless signal interference concerns that can occur in environments with multiple electronic devices or structural barriers. This connection method ensures consistent signal transmission regardless of weather conditions, building materials, or nearby equipment that might disrupt wireless systems. The wired approach provides reliable operation that security systems require for dependable perimeter protection.
Application and Placement Guidance

The detector's shooting detection angle creates precise monitoring corridors rather than broad area coverage. This characteristic makes it particularly suitable for monitoring specific pathways, entry points, gateways, or boundary lines where controlled access monitoring is required. The black housing blends with various architectural styles while providing UV protection for outdoor installations.
Commercial Security Applications
Warehouses benefit from the detector's ability to monitor loading bays, perimeter fencing, and restricted access areas. Shopping centres can secure emergency exits, stock delivery points, and after-hours entryways. The system's temperature tolerance ensures reliable operation in both climate-controlled indoor environments and exposed outdoor installations common in commercial settings.
Residential Protection Scenarios
Villa perimeter walls, garden boundaries, driveway entrances, and patio access points represent typical residential applications. The detector's adjustable range accommodates various property sizes, from compact urban homes requiring 30-metre coverage to larger properties utilising the full 150-metre capability. Community spaces including shared facilities, playground perimeters, and communal building entrances also represent suitable installation locations.
Practical Benefits and Operational Value

This infrared detector provides straightforward security monitoring without complex programming or frequent maintenance requirements. The system's simplicity contributes to reliable long-term operation, while the wired connection ensures consistent performance regardless of environmental factors that might affect wireless alternatives.
Reliability Through Simplicity
The detector's design prioritises operational reliability through technical simplicity. With fewer components than multi-sensor systems, there are fewer potential failure points. The specified temperature range ensures operation across seasonal variations, while the low static current consumption reduces power supply requirements. These characteristics combine to create security monitoring that functions consistently with minimal ongoing attention.
Security Monitoring Without Complexity
Unlike security systems requiring extensive configuration or regular recalibration, this infrared detector provides essential perimeter monitoring through straightforward installation and operation. The pair-based setup creates complete monitoring corridors without additional components, while the adjustable distance allows customisation to specific security needs. This approach delivers practical protection without unnecessary complexity that can complicate maintenance or troubleshooting.
