2 Beam 150 Metre Infrared Anti-Theft Alarm with Adjustable Detection for Perimeter Security

This infrared anti-theft alarm system provides reliable perimeter security through two-beam detection technology with a maximum range of 150 metres. Designed for commercial and residential applications including warehouses, shopping centres, residential communities, and villa properties, the wired communication method ensures consistent connectivity without the interference risks associated with wireless systems. The adjustable detection distance from 30 to 150 metres allows installation flexibility to match specific security zone requirements, whether securing a small storage area or monitoring extensive property boundaries.

Features and Construction

The alarm's core functionality centres on infrared beam technology that creates invisible detection zones across vulnerable entry points. The black housing provides discreet installation against various building materials and structures.

Material and Build

The alarm housing is constructed from plastic materials suitable for both indoor and outdoor installation, though specific plastic composition details are not provided. Infrared sensor components form the detection mechanism, with two beams creating the security zone. The wired communication method uses physical connections between components, eliminating wireless signal disruption concerns.

Size and Practical Fit

While specific dimensions are not provided, the alarm's design focuses on functional installation rather than compact aesthetics. The adjustable detection distance from 30 to 150 metres accommodates various installation scenarios, from narrow corridors to wide perimeter boundaries. Proper alignment between paired detector units ensures optimal beam connection across the intended security zone.

Uses and Placement

This infrared alarm serves multiple security applications across commercial and residential settings, focusing on perimeter protection and entry point monitoring.

Event or Professional Use

Warehouses benefit from the 150 metre detection range covering loading bay entrances and storage perimeter fencing. Shopping centres can install the system across service entrances, delivery areas, and after-hours access points. The wide temperature tolerance from -25°C to 55°C ensures reliable operation in both refrigerated storage environments and sun-exposed exterior locations.

Everyday Home Use

Residential communities and villa properties utilise the system for perimeter wall security, gate monitoring, and boundary protection. The adjustable detection distance allows customisation for different property sizes, while the black housing blends discreetly with exterior walls and fencing. Paired installation creates complete detection zones across driveways, garden boundaries, and building access points.

Benefits and Buying Value

The alarm offers practical security advantages through reliable detection technology and flexible installation options suitable for various environments.

Reuse and Low Maintenance

The wired communication method provides consistent performance without battery replacements or wireless frequency adjustments. The 12V operating voltage with 3mA static current consumption maintains low energy requirements for continuous operation. Temperature tolerance from -25°C to 55°C reduces seasonal maintenance needs and ensures year-round reliability.
