In the prison environment, controlling and searching for mobile phones is a key measure to ensure safety and order. Mobile phones can be used for illegal activities such as smuggling, planning escapes, or riots, and can also serve as communication tools, affecting the management and security of the prison. Therefore, prison management must adopt efficient technologies and strategies to monitor and restrict the use of mobile phones.

Usage Scenarios:

Mobile Detection: Prisons can detect mobile phone activity in specific areas through non-contact methods. If any abnormal or illegal use is detected, the system immediately triggers an alarm.

Location Searches: With initial mobile phone positioning, law enforcement can accurately locate the target phone, facilitating quick response and handling of violations.

Black and White List Management: By implementing a black and white list system, officially sanctioned phones on the white list are allowed to operate normally, while phones on the black list that are unreported or illegally used are detected and alarmed.

Through these measures, prisons can not only effectively prevent security issues caused by mobile phones but also maintain a good regulatory environment and social safety.
