Prison is a high-risk and highly serious special area, where drones are used for smuggling, as a means of investigation for escaping or robbing prisoners, and the use of drones to smuggle tobacco, drugs, and even weapons and prohibited items inside the prison has become a key safety hazard in prison management. More and more prison management agencies are working to strengthen drone prevention and control capabilities. The Bohong drone defense system adopts integrated equipment for drone detection, positioning, and photoelectric directional countermeasures, establishing an overall low altitude defense system to enhance the ability of the prison to detect, prevent, and dispose of low altitude drones, in order to ensure the safety of sensitive areas in low altitude airspace.
