Portable 2G/3G/4G IMSI Catcher

Nowadays, people always carry their phones with them. Having intelligence on a particular person’s phone equates to managing info on a person. The HELIOS® Smart IMSI Catcher solutions for Safe Cities is a unique low-cost, precious sensor system that offers an exciting new way to protect borders, point of entry and sensitive locations, it delivers real-time, always-on, presence-based 2G/3G/4G cellular detection and enables an organization (such as government agencies, border agencies, and law enforcement agencies with exceptional and precise levels of location data for use in security and border protection systems.

The HELIOS® P240 2G/3G/4G Portable Smart IMSI Catcher system adopts specially compact design to allow mounted on the car or carry with law enforcement officers, and enables law enforcement agencies to flexible & fast gather the target’s phone identity (IMSI, IMEI or MSISDN) and precise orientation by air scanning with portable directional antenna base on DTOA and AOA measurement technology.

HELIOS® Smart IMSI Catcher system also delivers the first stage of smart situation management and intelligence investigation or tracing. It can be integrated to other system and sensors for producing maximal value of data provided by the HELIOS® Smart IMSI Catcher system. For example: smart surveillance cameras, face recognition, biometric systems, scanners, LPR (license plate recognition) system, border checkpoints and any other system. All of data information can be used to help track some of the challenges we face today:

  • Handling threats to critical infrastructure elements such as power, transport and utilities
  • Tracking person of interest to prevent serious crime
  • Preventing and reacting to emergency situations

The built-in algorithms of auto configuration implemented in each module analyzes radio environment of existing base stations in the area where it is placed in service, extract critical parameters and set the parameters for each carrier to be optimal in terms of efficiency and capture time.

  • Support up to multiple bands/carriers in a single chassis basis on customization requirement
  • Extraction of IMSI and IMEI in 2G, 3G and 4G
  • Support capture Wi-Fi MAC in 2.4GHz and 5.8GHz
  • Target selection and automatic alert
  • Max 4000 targets capacity
  • Support redirecting between 2G and 4G/3G
  • Auto configuration by scanning radio environment of existing base stations in the area
  • Min receive sensitivity -105dBm@20Mbps, 64QAM
  • Built-in 3G/4G wireless modem for wireless data backhaul
  • The capture process can be quickly completed within 100ms and the user is released back to the macro network to ensure that the user is not aware of it.
  • Accurate gathering successful rate as >98% on walking or >95% moving up to 160KM/hour
  • Support setting black list and white list
  • Support flexible three capture operation mode as full gathering, full release or cyclicity
  • RF composited power up to +40dBm per band
  • Embedded IP WEB GUI for all local and remote configuration
