In the field of anti-theft alarm, there are many perimeter prevention technologies that are currently popular, such as vibrating cables, outdoor three-gauge probes, leaking cables, tension fences, electronic fences, infrared beaming and other technologies. The perimeter alarm system uses technologies such as leakage, infrared, and electronic fences to form a visible or invisible "protective wall" at the boundary of the protection, for outdoor prevention, especially for residential areas, industrial parks, and substations with a large space. In other places, mainstream devices such as infrared radio/electronic fences are mainly used. However, judging from the current situation in the country, there are very few that have been used for a long time, and most of them have become a kind of decoration. The main reason is the poor anti-interference ability. It is prone to false alarms due to the influence of the natural environment, including various light interference, strong magnetic interference and bad weather. Therefore, the application of active infrared detection products in our country is still limited. The main reason is the problem of the product itself, which is restricted by the characteristics of the infrared light source.
Using laser as a detection light source has many advantages. After years of research and hard work, Elion has successfully solved the problems of laser stability, safety, and adaptability. The company's first active laser intrusion detector is a new generation of revolution in the field of anti-theft alarms. The product can greatly expand the application space of the anti-theft alarm field, and can bring new changes in the application concept, mainly including the following aspects:
The laser has strong anti-interference and stability
The application of a new generation of anti-jamming technology for laser beam detectors makes the normal operation of the equipment not affected by the natural environment, and can work normally even in a strong light environment with 50,000 illuminance, whether it is raining or snowing, or even fog In the haze and dusty weather, the product can also work normally, which greatly enhances the stability and reliability of the product.
It supports normal work under strong sunlight, and also supports normal work in a relatively 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 alarm rate
It makes the transmission and reception of laser beam products safe and reliable, and it is not easy to produce false alarms. Coupled with the outstanding anti-interference ability of laser beams, it can achieve a precedent of close to zero false alarms, which may be the current false alarm in the anti-theft alarm market. The perimeter alarm product with the lowest reporting rate. There is a precedent of no false positives after one year of use, creating a myth that traditional products cannot be surpassed.
No special requirements for installation direction
Since the laser beam is not interfered by the sunlight, there is no special direction requirement for the laser beam during installation. The receiving host can be installed directly in the direction of the sunlight, and the direct sunlight receiver will not produce false alarms. It supports strong Normal arming work under sunlight. Not affected by the surrounding natural environment.
Advantages of laser beam
1. Long detection distance and low false alarm rate
Compared with similar active detection systems, the laser intrusion detection system is significantly more adaptable to harsh climate environments. The power density of the laser beam is large, the divergence angle is small, the beam is concentrated, and the directionality is good. Under the condition of using the same power device, the power density of the target receiving laser beam is several times that of the infrared light-emitting diode beam, so it penetrates Rain, snow, fog, wind and sand are strong, which greatly reduces the false alarm rate.
2. Strong anti-interference, no interference to other equipment
The laser alarm system itself is strong against electromagnetic interference, and there is no electromagnetic interference to the area and equipment outside the warning laser beam propagation path. Due to the small divergence angle of the laser, the beam is concentrated.
3. Strong precaution
Can implement continuous cross arming without mutual interference.
It can implement multiple independent beam plane and spatial three-dimensional distribution.
4. Wide adaptability
The response time of the laser detector is adjustable between 50-700ms, and the response time can be customized according to the different on-site environments where the equipment is installed, so as to adapt to a wider range of environments.
It can work normally in the environment of -40°C～70°C without any electric heater.
The output of the laser alarm system is a potential-free contact, which is compatible with various other systems.
5. Can work around the clock
As a highly concentrated light source, laser was used in aerospace and military facilities in the early days. The Arion Laser Intrusion Detector uses military-grade laser emitting and receiving devices as the main components of the detector to make the product resistant to detection distances. Interference and stability are better than traditional active infrared through-beam, infrared grating and other detectors. Therefore, they have been widely used and affirmed by users from all walks of life once they were launched. It has been successfully applied to airports, subways, national borders, and large-scale projects. Equipment protects airports, various training grounds, factory perimeters, farms, etc. It is an important intrusion detector in the modern security field.
In laser detectors, with the development of security technology and the maturity of the security market, as well as the further improvement of policies and regulations, digitalization, integration, and networking will be the inevitable trend of its development. What follows is the integration of security product technology Advancing with the times and continuing to innovate, only in this way can we adapt to market development and needs. I believe that more security companies will launch more specialized/intelligent security equipment under the background of this networked/intelligent era, and promote the development of the security industry. Step development.
