In modern cities, high-rise buildings stand up, and the complexity of the buildings is increasing day by day. They are not only a symbol of urban prosperity, but also the crystallization of human wisdom and creativity. However, behind this glamorous and beautiful appearance, there is a hidden safety hazard that cannot be ignored - the vast space of the ventilation system, which is like the hidden veins of the city. Although it is indispensable, it may also become a hotbed of potential threats.

The ventilation system, as the life breathing system of modern buildings, is responsible for regulating indoor air quality and maintaining a comfortable and healthy environment. However, such a complex network, due to its complex structure and difficulty in reaching,it often becomes a hidden corner for criminals to hide, spread harmful substances or carry out illegal activities. Therefore, how to effectively supervise this blind spot and ensure public safety has become an urgent problem for city managers and law enforcement agencies to solve.

In this context, the security inspection borescope came into being. It is like a pair of sharp electronic eyes that penetrate the darkness and depth of the ventilation duct and become a powerful assistant for the police and security departments to detect hidden dangers.
