Phone number Detection System

Portable Mobile Phone Number ,IMEI and IMSI Detection System

1. Brief introduction of the system

Owing to high recurrences and complexity of social problems and conflicts, it has become more and more important and urgent for police and security authorities to catch and process mobile phone information of certain group of people or certain person by using modern high-tech means. The warning and positioning of suspects become increasingly important. The Mobile Phone Detecting System we developed is in this background for special applications. It can meet the special application needs such as technical investigations, criminal investigations, national security, drug controls, anti-terrorism, customs anti-smuggling, anti-crimes by detecting and acquiring mobile phone number, IMSI(SIM number), IMEI(mobile hardware number), etc. without users’ awareness. Aiming at special scenarios, we developed this new portable, high efficient and cost-effective mobile phone detecting system.

The main device of the system contains two operating modes: local control and remote centralized control. The former does not need network, and can detect the target mobile phone whenever and wherever needed; the latter logs into the public network and upload the data to the data center or server which is under unified management. We have management software for powerful data processing, such as White/Black name list, Suspected Number Alarming, Electronic Map, Path Tracking, Relevant Number generating, etc.

2. The application scenarios

Fixed indoor: public places such as cybercafes, banks/ATM, hospitals, ticket offices, etc. They are deployed where people have to wait or stay.

Fixed in vehicle: moving with the vehicle to search, follow and make
detecting at target people or vehicles.

Portable mode: it is convenient for plainclothes police to carry with them
to follow, search and make detection at airports, hotels, stations, streets,
nearby apartments, etc.

3. Functions and features of the device
1. Operate independently without support from any third-party in
interface or network, and can detect and record mobile phone
numbers and other information like IMEI, IMSI quickly and
secretly.
2. Simple and easy maintenance after implementation, never produce
any call or text message costs.
3. Small and hidden, which can be put in an ordinary laptop
briefcase.
4. It has a built-in oriented antenna, which can lock the target. The
searching distance can be adjusted from 0 to 20 meters.
5. The starting up system can work automatically without 

configuring parameters, which avoids man-made configuration
and interference.
6. Local cellphone control the mainframe. It has high concealment
and easy operation procedure.
7. Automatically sense the change of surrounding mobile network.
8. It sends the detected mobile phone information back to public
network in 3seconds after collecting without users’ awareness.
9. It can send the collected mobile phone information to the network
server after connecting. The software of sever platform contains
strong processing capacity such as electronic map, data analysis,
cluster management, etc.
10. It is convenient for clients to make a second exploitation with
interfaces provided.
