Problems solved by technology

[0003] For the perimeter anti-intrusion alarm system, infrared detection technology and infrared microwave double-detection technology are generally used for detection. The main products are infrared intrusion detectors and infrared gratings, but these infrared detection products have higher requirements on the environment. When the environment changes, such as tree branches, strong light, animals coming in and out, or heavy wind and rain, it is easy to generate false alarm information, and the false alarm rate is high
[0004] The commonly used perimeter protection product is the high-voltage pulse tension electronic fence, which uses high-voltage, low-energy pulses. Although it will not cause direct harm to the human body, if it is accidentally touched, it may cause a strong electric shock. Indirect injuries such as falling; sometimes electric sparks are generated, so it is not suitable to use in an environment with flammable gas, and it is necessary to keep a sufficient distance from the power line
[0005] The traditional tension electronic fence has both blocking and alarm functions. The exposed mechanical parts are not charged, and will not cause direct or indirect damage to the human body. It is safer and more reliable to use. It is a green electronic fence, but its defense area is not adjustable. Not suitable for harsh environments, inconvenient for installation and debugging
