Wall Mounting IMSI Finder

IMSI catcher, also known as 4G micro-power code detection equipment, is mainly used as an important auxiliary equipment for quick and accurate search when the public security, security, security and other departments need to find relevant personnel. It supports 4G user information collection, mainly collects IMSI, IMEI and MAC address, etc. It is an active mobile phone feature code collection device, based on the working principle of wireless communication base stations and adopts relevant technical solutions for small base stations. The product has the technical advantages of small size, low power consumption, high degree of intelligence, easy maintenance, and customized back-end function management. It can be widely used in national security and public security. The IMSI finder has built-in GPS antenna, wireless return antenna, LTE high-gain directional antenna, high integration, few external interfaces, and convenient construction. It can also be equipped with cameras, public security illegal big data, individual search equipment and other professional equipment in different fields to combine into different equipment packages. Support 2G/3G/4G full frequency band, ultra-high-speed signature collection, invisible direct collection, without interfering with mobile phone communication; product forms include fixed, mobile, and portable; it can meet the deployment in different environments such as indoor, outdoor and confidentiality use.

Specification

Application Examples

By deploying multiple code detection base stations, the data platform can perform collision and analysis based on the data returned by multiple code detection base stations, so that it can play a key role in the entire process from predicting and preventing crimes to detecting cases and arresting criminal suspects.

5.1 Resident population

It is possible to distinguish mobile personnel from permanent personnel. For mobile personnel, due to the short stay in the monitoring area, the system can only collect once or several times. Resident personnel are often collected for a long period of time. By distinguishing between mobile personnel and permanent personnel, the scope of suspects can be greatly reduced and the target can be targeted as soon as possible.

5.2 Target monitoring

Enter the key monitoring target identification numbers such as IMSI and SUPI into the system. Once the target appears at the monitoring point, the system finds and pushes an alarm to notify the supervisor of the time and location of the target, thus achieving effective monitoring of the target.

5.3 Adjoint analysis

When the system collects the identification information of the target, it will also collect the identification information of the pedestrians in a similar time. Through the accompanying analysis function provided by the system, the information of other people who often walk with the target can be obtained. These people are closely related to the target. Combining the analysis of the gang’s activity area and the place where the crime occurred, the gang’s crime can be solved.

5.4 Trajectory analysis

After the system is running, it continuously collects the information of all personnel in the past monitoring area. After a period of time, the system obtains the information of all personnel entering and exiting each monitoring area during this period of time. By querying the information that the target person appears, the movement track of the target can be obtained according to the time when the target appears at each monitoring point and the location of the monitoring point.
