Product Overview
The NHR‑T05 electronic fence is an active intrusion detection device, also known as a laser beam barrier. It consists primarily of a laser transmitter and a laser receiver. The transmitter emits one or multiple modulated laser beams toward the receiver; these beams exhibit excellent directivity and phase coherence, forming one or more invisible laser warning lines. The laser beam barrier operates by detecting interruptions in the laser beam to trigger an alarm. If the laser beam between the transmitter and receiver remains unobstructed, the system remains silent; however, if the beam is blocked, the system immediately activates the alarm.
The NHR‑T05 electronic fence boasts a long detection range, high sensitivity, a low false‑alarm rate, robust safety and reliability, excellent concealment, convenient maintenance and commissioning, and adaptability to a wide variety of harsh environmental conditions. It is widely applicable for security monitoring and early warning in settings such as prisons, military facilities, residential areas, industrial plants, warehouses, substations, and petrochemical sites.

Module Functions
● Supports intelligent frequency‑hopping technology, with each beam assigned a unique transmit and receive frequency, effectively reducing crosstalk interference between beams.
● Alert distance: 0–300 m;
● It employs a four-digit LED display, enabling real-time monitoring of minute variations in each beam’s signal.
● Supports configuring alarms to detect obstruction of a single beam, two beams, or multiple beams, making it suitable for a wide range of environmental applications.
● Supports switching between working mode and debugging mode, optimizing complex operations during optical alignment.
● Featuring a non‑visible laser light source, this design ensures more discreet and safer operation.
● Equipped with a premium imported original laser head, boasting a service life exceeding 150,000 hours;
● The laser light source is classified as Class I; under normal operating conditions, it does not expose the eyes to hazardous optical radiation.
● Enhanced laser penetration effectively mitigates interference from adverse natural conditions such as wind, frost, rain, snow, and fog, resulting in improved stability.
● Each beam supports vertical and horizontal angle adjustment; beam axis adjustment range: horizontal ±15°, vertical ±15°.
● The top of the laser beam‑to‑beam system is equipped with a bracket‑mounting interface, allowing for the installation of infrared cameras, alarm lights, floodlights, and other devices.
● The beam spacing is 15 cm, effectively reducing false alarms and missed detections (customizable beam spacing available upon request);
● Alarm trigger response time is selectable at 50 ms, 100 ms, 300 ms, or 700 ms (customizable to meet specific requirements);
● With an IP67 protection rating, it can operate normally even when submerged in water up to 1 meter deep.
