Vehicle-Mounted IMSI Catcher

As we are certain that you are aware, people always carry their mobiles with them. Having intelligence on a particular person’s phone equates to managing info on that person. The HELIOS® Smart IMSI Catcher solutions for Safe Cities is a unique, precision sensor system that offers an 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 and mobile phone data.

The HELIOS® P340 2G/3G/4G vehicle-mounted Multi-Band Multi-Operator Smart IMSI Catcher system adopts an especially compact design to allow it to be mounted on a Police or Security Department Vehicle to be used by Law Enforcement Officers. It is enclosed in a durable case, and enables Law Enforcement Agencies to gather a target phone’s identity (IMSI, IMEI or even SIM # in 2G mode) and precise location by scanning with mounted directional antennas based upon DTOA and AOA measurement technology.

HELIOS® P340 2G/3G/4G vehicle-mounted Multi-Band Multi-Operator Smart IMSI Catcher system also delivers the first stage of smart situation management and intelligence investigation or tracing. It also can be integrated to other systems and sensors for producing maximal value of data. For example: smart surveillance cameras, face recognition, biometric systems, scanners, LPR (license plate recognition) system, border checkpoints and any other system.

  • 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 that are implemented in each module, analyzes the radio environment of existing base stations in the area where it is placed in service, extracts critical parameters and sets the parameters for each carrier to be optimized in terms of efficiency and capture time.

  • Supports multiple bands/carriers in a single chassis based upon customization requirements
  • Extraction of IMSI and IMEI in 2G, 3G and 4G (even SIM number in 2G mode)
  • Supports capture of Wi-Fi MAC in 2.4GHz and 5.8GHz
  • Target selection and automatic alert based upon preset suspect lists
  • Max 4000 target capacity
  • Support redirecting between 2G and 3G/4G
  • 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
  • Accurate gathering successful rate as >98% on walking or >95% moving up to 160km/hour
  • Supports setting black list and white list
  • Supports flexible three capture operation mode as full gathering, full release or cyclicity
  • RF composite power up to +33dBm per band
  • Embedded IP WEB GUI for all local and remote configuration
