Application of Fixed IMSI Catcher System in Urban Security and Control

Currently, the Fixed IMSI Catcher system has been widely applied in the field of urban security and control. The device is fixedly installed at specific locations, capable of constructing an invisible signal coverage area. It can quickly capture mobile phone signals entering its monitoring range, collect key information such as IMSI/IMEI, and aggregate the collected information to a unified server for AI analysis via the Data Platform.

Based on product form, power, and volume, it can be categorized into Macro Fixed IMSI Catcher and Micro Fixed IMSI Catcher. Macro Fixed IMSI Catcher features a large coverage area and can be deployed along urban main roads, at important road intersections, administrative boundary junctions, concentrated crime locations, etc. Micro Fixed IMSI Catcher has a smaller coverage area and can be deployed at entrances and exits of transportation hubs such as railway stations and bus stations, as well as key locations, to realize mobile phone monitoring.

1. Longer distance and larger scope for security control.
2. It is not affected by rain, snow, fog, night and other weather and environmental conditions, as well as factors such as obstruction and evasion by illegal personnel.
3. Highly concealed and not easily detected.
4. No manual patrols required, reducing labor costs.
5. Strong data analysis capability, enabling early perception and proactive warning.
6. Simple operation, reliable quality, and easy maintenance.

1. Analyze suspects' mobile phone information based on their crime locations.
2. Analyze accomplices based on the mobile phone information of target individuals.
3. Depict the activity trajectories of target individuals.
4. For the location where the target appears, timely early warning and prompts are provided.
5. Conduct real-time monitoring of the regular locations of specific targets.

The Fixed IMSI Catcher system has been widely applied in many cities. Its efficient capabilities in data collection, analysis, and warning play a significant role in combating crimes, maintaining social security and stability, and protecting people's lives and property. In the future, we will develop more data application models to extend the application of Fixed IMSI Catcher to more scenarios.
