With the continuous development of the social economy, people's lives are improving day by day, and people pay more and more attention to the safety of family life and property. The demand for household anti-theft alarm devices is also expanding, and the types of anti-theft alarm devices that we commonly use nowadays are commonly divided into "perimeter anti-theft alarms" and "outdoor anti-theft alarms". Its role is to prevent illegal persons from overtaking theft and protect our personal and property safety. In fact, in addition to our anti-theft alarm equipment, gas detectors and flood detectors are also essential in home security. These detectors Mainly used in kitchens and other places. To protect family safety and avoid accidents. Today, Keou will explain the two types of products: "Perimeter Anti-theft Alarm" and "Indoor Anti-theft Alarm".
Perimeter anti-theft alarm
(1) Electronic fence
Installed on the wall, it can play the role of blocking, alarming and warning. Generally used in residential areas, government and enterprise units, etc.
The advantages of electronic fences are:
1. Low false alarm rate;
2. The environment has good adaptability and can be installed on different terrains;
3. High deterrence;
4. Beautify the environment;
5. With blocking and anti-climbing functions.
(2) Tension fence
It is installed on the surface of the surrounding wall and alarms according to the change of tensile force. It is generally used in schools and other places.
Advantages of tension fence:
1. Beautify the environment;
2. The environment has good adaptability and can be installed on different terrains;
3. No voltage current on the front tension line;
4. With blocking and anti-climbing functions.
(3) Infrared beaming
Wired infrared is mainly used for power supply and signal transmission through cable.
Advantages of infrared radiation:
1. Transmission using cable is not easily affected by external interference;
2. Due to the active power supply, the infrared distance is relatively long;
3. Less influence from environmental factors.
(4) Laser shooting
The laser beam is mainly used for anti-theft alarm through the signal transmission of the transmitting end and the receiving end.
Advantages of laser beam shooting:
1. Strong beam penetration and low false alarm rate;
2. Strong environmental adaptability and long detection distance;
3. With explosion-proof effect, flammable and explosive areas can also be used;
4. Strong resistance to external damage.
Indoor anti-theft alarm
(1) Infrared detector
Anti-theft detection is performed by detecting infrared rays emitted by the human body. According to different installation methods and detection range, it can be divided into wall-mounted infrared detector, ceiling infrared detector and curtain infrared detector.
Infrared detector advantages:
1. Wall-mounted push-pull integrated installation, convenient and fast;
2. High detection sensitivity and accuracy;
3. Can perform automatic temperature compensation;
4. Large detection angle, no dead angle detection.
Surfacing hardness is 63 degrees; it still has high wear resistance in high temperature working conditions of 500 °-° 600 °, and the tempering hardness HRC63 remains unchanged. The wear resistance is 20-25 times that of low carbon steel, 5-10 times that of stainless steel and high manganese steel, and 1.5 times that of general high carbon high chromium wear-resistant steel plates. It can be curled, and it can be curled with different curvatures according to the thickness of the motherboard.
