How to prevent thieves if you are away from home for a long time

At the end of the 20th century, intelligent system engineering entered a period of rapid development with the widespread application of modern information technology, network technology and information integration technology. In less than 20 years of development, China's intelligent buildings have sprung up. Its rapid development and grand scale are unique in the world, fully reflecting the ingenious integration of technology and modern architectural art. Safety precautions have become an important part that people cannot ignore! Tell us about the advantages and reliability of today's safety protection.

The so-called intelligent system safety protection project is a comprehensive safety management system composed of combined equipment and systems based on the perimeter anti-theft alarm platform. One of the basic goals of the intelligent system security protection project is to provide the public with highly safe, effective, convenient and flexible services. Perimeter anti-theft alarm system plays an irreplaceable role in smart communities, villas, substations, etc. The system must be able to follow international standard communication protocols and have the ability to upgrade and be compatible with the system in order to ensure that the intelligent system will For a long period of time, it can continuously expand, upgrade and further improve the integrated functions of its system.

Anti-theft alarm system for perimeter of residential area

According to the scale of the perimeter of the building, the current perimeter anti-theft alarm system for residential districts can form a multi-device anti-theft alarm system through the following three levels of precautions.

The first level of precautions- intrusion detector

Ordinary infrared series: any object will radiate infrared rays with different strengths due to different surface heat. Due to different objects, the infrared wavelengths radiated will also be different. Ordinary infrared detectors use this method to detect the human body. Infrared detection is mainly used to detect the human body and other invading moving objects. When the human body enters the detection area, the stable thermal radiation is destroyed, generating a changing thermal radiation. The infrared sensor is amplified, processed, and emits an alarm signal after receiving. Intelligent direction curtain series: This kind of product uses its distinguished direction recognition technology to accurately distinguish between the enemy and the enemy. It is very suitable for the prevention of the entire plane such as balconies and windows. The intelligent direction curtain series is a high-performance directional detector, which is composed of a passive infrared double-curtain detection device and a fuzzy logic digital core. Among them, the four-curtain direction recognition detector has a fascinating streamlined appearance design and a unique DSP. Analyze the direction of intrusion, increase the anti-false alarm capability by 3 times, and increase the response speed by 10 times.

Microwave Infrared Intelligent Double-Check Series: This series is one of the commonly used equipment in the alarm system. Its working principle integrates infrared and microwave. When the infrared and microwave detectors have alarm signals at the same time, the detector will have an alarm output, which greatly reduces the probability of false alarms. There are many models of infrared microwave intelligent dual detector series, corresponding to different detection distances, some can detect a fan-shaped area, some can detect a narrow and long section (such as a corridor), and some can detect 360 degrees, so it must be based on specific needs To choose the right model, so as to achieve the effect. In addition, the sensitivity of the detector is generally adjustable; as the originator of the digital three-detector detector, the three-sensor three-dimensional analysis technology recently introduced by Deter Group has created a new standard for outdoor defense and perfectly interpreted the advanced concept of anti-line shift ( (Alarm before entering the room), provide a strong guarantee for the first-level preventive measures of the multi-dimensional networked alarm system.

The second level of preventive measures-anti-theft alarm host

The anti-theft alarm host is responsible for receiving the alarm signal, controlling the delay time, and driving the alarm output. It combines all the intrusion detectors in a certain area to form an anti-theft tube area. Once an alarm occurs, the area can be clearly reflected on the anti-theft host. At present, most anti-theft alarm hosts are controlled by microprocessors, with read-only memory and digital display devices, which are generally programmable and have high intelligence. According to the type of defense area, they are divided into the following models:

Home system: Generally, the number of home defense zones is small, so the alarm host should be powerful, use a simple voice operating system, and use several types of products that are suitable for (Anchuangming St. Electrostatic Intrusion Detection System, British Rotland Pulse Electronic Fence;

Commercial system: For commercial systems with a relatively large number of defense areas, such as shops and small office buildings, an alarm host with a large number of defense areas can be used, and an electrostatic induction intrusion detection and alarm system can be used;

Community system: For large-scale residential communities or other areas that need to be managed in a unified manner from multiple different buildings, an alarm host compatible with multiple mainstream protocols can be selected.
