In the field of burglar alarm, there are many popular perimeter defense technologies, such as vibration cables, outdoor three-detection probes, leaky cables, tension fences, electronic fences, and infrared radiation. The perimeter alarm system uses a technology such as leakage, infrared, electronic fences to form a “protective wall†that is visible or invisible at the boundary of protection. For outdoor prevention, especially for residential areas, industrial parks, and substations with large space. Main places such as infrared radiation/electronic fences are mainly used in other places. However, from the current situation in the country, there are very few real-time applications, and most of them become a kind of display. The reason is mainly due to the poor anti-interference ability, which is susceptible to false alarms due to the influence of the natural environment, including various optical interferences, strong magnetic interference and bad weather. Therefore, the application of active infrared detection products in China is still limited, mainly because of the problem of the product itself, and is subject to the characteristics of the infrared light source.
The laser as a detection light source has many advantages. The Viandas laser technology team has successfully solved the problems of laser stability, safety and adaptability after years of research and development. The company's first active laser intrusion detector is new in the field of anti-theft alarm. A generation of revolutionary products that can expand the application space in the field of burglar alarms, can bring about new changes in the application concept, mainly including the following aspects:
Laser anti-interference and stability
The application of the new generation of anti-jamming technology for laser detectors makes the normal operation of the equipment unaffected by the natural environment. It can work normally even under the glare of 50,000 illuminance, whether it is raining or snowing, or even fog. In the dusty weather, the product can also work normally, which greatly enhances the stability and reliability of the product.
Supports normal work under strong sunlight, and supports normal operation in a harsh environment - 40 degrees to +70 degrees Celsius, without false alarms, and the product can be used in any place on the ground at home and abroad.
Ultra-low false positive rate
It makes the launching and receiving of laser-based products safe and reliable, and it is not easy to produce false alarms. In addition, the anti-jamming capability of laser beam is outstanding, and it can achieve the precedent of close to zero false positives. It may be the current burglar alarm market error. A perimeter alarm product with a very low rate of reporting. There have been precedents for the use of a year without false positives, creating a myth that traditional products cannot be surpassed.
No special requirements for installation direction
Since the laser beam is not interfered with by sunlight, this makes the laser beam have no special direction requirements during installation. The receiving host can be installed in the direction of sunlight, and the direct sunlight receiver will not generate false alarms. Support is strong. Normal arming work under the sun. Not affected by the external natural environment.
Advantages of laser beaming
1. The detection distance is long and the false alarm rate is low.
Compared with similar active detection systems, laser intrusion detection systems have significantly improved adaptability to harsh climates. The power density of the laser beam emission is large, the divergence angle is small, the beam is concentrated, and the directivity is good. At a distance of 100 meters under the condition of the same power device, the power density of the target receiving laser beam is several times that of the infrared light emitting diode beam, thus penetrating The ability of rain, snow, fog and sand is strong, which reduces the false alarm rate.
2, strong anti-interference, no interference to other equipment
The laser alarm system itself is highly resistant to electromagnetic interference and does not have any electromagnetic interference to areas and equipment outside the warning laser beam propagation path. Since the laser divergence angle is small, the light beam is concentrated.
3, strong preventive
Continuous cross-arming can be implemented without mutual interference.
Multiple independent beam planes and spatial stereoscopic distributions can be implemented.
4, wide adaptability
1. The response time of laser detector is adjustable between 10500ms (the response time of similar products is between 50500ms). The response time can be customized according to the different on-site environment of equipment installation, and it can adapt to a wider range of environments.
2. It can work normally in the environment of -40 ° C ~ 70 ° C, without any electric heater.
3. The laser alarm system output is a potential-free contact, which is compatible with various other systems.
4, can work around the clock
