DDSK-J Series Laser Ultra-Long Distance Security Alarm System
The alarm point is equipped with a 2-zone IP network module, which can connect up to 2 detectors at most and can be deployed or disarmed locally through the keyboard.
Users can also choose the zone expansion module to connect the detectors they use, or they can uniformly arm or disarm through the alarm center.
Once an alarm occurs at one or more alarm points in the alarm reporting system, all sub-alarm points of the same system can display information and sound and light alarm alerts through the keyboard, and accurately know the details of the alarm detector at a certain alarm point.

Single beam laser interfacing (second generation laser):
The use of four-digit digital tube display, real-time display of each light beam signal small changes, debugging is simple and convenient.
Support the working mode and debugging mode switch, optimize the complex operation of the light.
The use of non-visible laser light source design, so that the product use more hidden, more safe.
Selected imported original laser head, service life > 150,000 hours.
The laser light source grade is Class Ⅰ, under normal circumstances, will not make the eyes suffer from harmful optical radiation.
Laser penetration is stronger, can effectively inhibit the wind, frost, rain, snow, fog and other harsh natural environment interference, better stability.
The beam support up and down, left and right Angle adjustment; Optical axis adjustment Angle: horizontal ±15°, vertical ±15°.
Standard support accessories, can be installed infrared cameras, alarm lights and searchlights and other equipment.
Alarm trigger response time 50ms/100ms/300ms/700ms optional (different alarm trigger response time can be customized according to demand).
The working principle of outdoor laser beam long-distance transmission is that the laser beam emitted by the laser emitter is precisely focused and then transmitted in a straight line. Under unobstructed conditions, the laser can travel in a straight line to the receiver. After the receiver captures the laser beam, it generates an electrical signal. After signal processing, if the laser beam is not obstructed during transmission, the receiver will output a high-level signal. Conversely, if the laser beam is blocked, the receiver will output a low-level signal.
Laser beam is an active intrusion detector, which consists of two parts: the laser transmitter and the laser receiver. The laser transmitter is composed of a voltage stabilizing power supply, a modulation circuit, a laser emission module, a laser angle adjustment device, and an external protective cover (shell). The laser receiver is composed of a regulated power supply, a photosensitive receiver, a photoelectric signal processor, a narrowband filter lens, and an external protective cover.
Product Introduction
The DDSK-J Series Outdoor Laser Beam Sensor is designed for long-range detection, offering reliable performance in various environmental conditions. With a detection range of up to 500 meters, it utilizes advanced laser technology to provide accurate and secure monitoring for both indoor and outdoor applications.
Frequently Asked Questions
How far can the DDSK-J laser beam detector reliably detect an intruder?
The DDSK-J Series provides an outdoor alert distance of 0 to 500 metres, with single-beam laser models configurable at 100, 200, 300 or 500 m. Because it uses a focused laser beam rather than a wide infrared cone, it holds a tight straight-line path over long perimeters, making it suitable for long fence lines, riverbanks and large open sites.
Is the DDSK-J laser source safe for the human eye?
Yes. The DDSK-J uses a Class 1 (Class I) laser light source, which under normal use will not cause harmful optical radiation to the eyes. It is offered in a 660 nm visible version for easy alignment and a 980 nm invisible version for covert outdoor perimeter protection, so the beam path is not obvious to an intruder.
How does the beam-occlusion alarm reduce false alarms outdoors?
Alarm mode is adjustable between adjacent 1, 2 or 3 beam occlusion, and the response time can be set to 50, 100, 300 or 700 ms. Requiring two or three beams to be blocked, with a longer response time, filters out small animals, leaves and brief obstructions, while the laser's strong penetration suppresses wind, frost, rain, snow and fog interference.
What IP rating and operating range does the DDSK-J have for outdoor use?
The detector is rated IP67 with a 304 stainless-steel shell, aluminium-alloy support column and die-cast aluminium base. It operates from -25°C to 70°C at up to 95% humidity, and the imported laser head gives an MTBF over 150,000 hours, so it withstands harsh outdoor perimeter environments year-round.
How are alarms reported and integrated into a security center?
Each alarm point carries a 2-zone IP network module that connects up to two detectors and can be armed or disarmed locally by keypad, or centrally through the alarm center using a zone expansion module. The alarm output is NO/NC selectable (contact capacity AC125V/0.5A, DC24V/1A max) so it ties into cameras, alarm lights, searchlights and existing panels.
