SZ Vodasafe VS-PJ6100NM Stationary IMSI Catching & Intelligent Jamming System
SZ Vodasafe VS-PJ6100NM is an upgraded stationary multi-band intelligent cellular signal management system, engineered for long-term fixed deployment in high-sensitivity restricted zones. Building on mature RF base station adsorption technology, this integrated solution merges passive airwave signal monitoring, covert IMSI/IMEI terminal capture, selective intelligent jamming, and full-cycle mobile signal data analysis into one compact outdoor cabinet unit.
Unlike conventional full-band blind jammers that block all cellular communications indiscriminately, the VS-PJ6100NM delivers classified communication control through dual whitelist and blacklist mechanisms. Within the device’s effective coverage radius, pre-authorized whitelist mobile terminals retain unobstructed calling, SMS and data access, while all blacklisted unauthorized devices will be fully isolated from public GSM, 3G, 4G LTE and 5G NR networks. The system captures active mobile device identifiers directly from over-the-air radio signals without requiring network rerouting or third-party operator cooperation; detection and target locking proceed covertly without triggering awareness from monitored mobile users.

Designed as a turnkey stationary security solution, the VS-PJ6100NM features an IP65 waterproof metal cabinet with integrated heat sink and fan cooling, supporting permanent outdoor pole-mounted installation. It seamlessly integrates with existing perimeter security, access control and video surveillance infrastructure, enabling 24/7 uninterrupted cellular signal supervision for core restricted sites including correctional facilities, military garrisons, confidential government compounds and other secure premises where unregulated mobile device usage poses severe information leakage risks.

Core Functional Advantages & Detailed Feature Description
1)Automatic Environmental Spectrum Survey
The system carries built-in full-band spectrum scanning modules that continuously auto-detect surrounding public cellular network frequency points and measure real-time signal strength of each operator band. After completing regional spectrum survey, the backend control software generates optimized RF configuration recommendations to balance jamming efficiency, coverage range and power consumption, eliminating manual frequency debugging and simplifying on-site deployment. Detected signal strength values of all nearby mobile terminals are displayed visually on the system operation screen for real-time signal screening.
2)Covert IMSI & IMEI Full-Spectrum Capture
The VS-PJ6100NM supports instant one-time capture and scheduled repeated cyclic collection of IMSI (SIM card subscriber identity) and IMEI (mobile device hardware identity) data for all active 2G/3G/4G/5G handsets within coverage. Its IMSI capture success rate reaches no less than 95%, ensuring virtually all powered-on mobile devices entering the monitoring zone are logged with unique identifiers, time stamps and signal intensity records for subsequent trace analysis.
3)Selective Intelligent Targeted Jamming
Powered by green base station adsorption jamming technology, the equipment realizes zero-blind-spot targeted signal suppression with a guaranteed 100% jamming success rate for all blacklisted targets. Operators can batch import multiple IMSI/IMEI identifiers into the blacklist library; once matching mobile terminals are detected, the system immediately cuts off all their cellular services including voice calls, text messages and mobile data transmission. Meanwhile, pre-registered whitelist devices are exempted from interference and maintain normal communication without bandwidth or latency loss. The system supports storage of at least 3,000 whitelist entries, with a stable whitelist pass-through success rate above 50%.

4)Fully Customizable Multi-Band RF Modules
All supported cellular frequency bands can be tailored to match regional operator network standards per client requirements. The standard pre-configured frequency spectrum covers LTE 700 (758–803MHz), GSM/LTE 900 (925–960MHz), GSM/LTE 1800 (1805–1880MHz), UMTS 2100 (2110–2170MHz), LTE 2300 (2300–2400MHz) and TDD 5G NR 3500 (3300–3600MHz). The system hardware supports up to 16 independent RF carriers and 16 directional antenna sectors, allowing flexible partitioned coverage of large compound areas such as dormitory blocks, training grounds, dining halls and perimeter fences.
5)Real-Time Perimeter Monitoring & Automatic Alarm
By deploying matched signal collection modules along facility boundary lines, the VS-PJ6100NM instantly identifies unauthorized or abnormal mobile devices crossing restricted perimeters. The system triggers real-time local and remote alert notifications upon detecting blacklisted terminals, paired with instant SMS alert pushes to security management staff. It maintains round-the-clock continuous scanning and monitoring across all designated restricted time windows and zones, supporting layered communication control rules for day-and-night differentiated management.
6)Spatiotemporal Big Data Analysis & Early Warning
All captured mobile terminal data is stored with precise detection timestamps and geographic sector labels. The backend management platform performs automated spatiotemporal correlation analysis of IMSI activity trajectories, cross-referencing device appearance frequency, movement paths and stay duration to flag suspicious recurring access, unknown frequent visitors and abnormal mobile activity hotspots. This proactive risk early warning mechanism enables security teams to identify potential communication leakage threats before incidents occur.
7)High-Precision Mobile Signal Location Matching
When paired with the optional portable direction finder accessory, the system delivers meter-level positioning for blacklisted mobile devices. Directional panel antennas cooperate with portable DF hardware to triangulate the exact physical position of unauthorized handsets, supporting rapid on-site inspection and confiscation of prohibited mobile equipment within secure zones.
8)User-Friendly Operation & Flexible Integration
The system adopts intuitive graphical operation software with simplified parameter configuration workflows, requiring minimal professional RF knowledge for daily operation. Standard RJ45 wired data interface enables stable connection with central security management platforms, while compatibility with existing surveillance, access control and alarm systems allows unified centralized monitoring of all site safety equipment. Synchronization modes include high-precision GPS clock synchronization and air interface network synchronization, with synchronization accuracy controlled within 0.1ppm to guarantee consistent signal processing across multi-unit deployments.
9)Industrial-Grade Outdoor Reliability
The main cabinet complies with IP65 full waterproof and dustproof enclosure standards, engineered for long-term pole-mounted outdoor installation without additional protective shelters. The integrated passive heat sink plus active fan dual cooling system stabilizes internal component temperature under extreme working conditions. The equipment operates reliably across a wide temperature range from -20°C to +55°C, and tolerates ambient relative humidity up to 95% without condensation damage. The mean time between failures (MTBF) of the complete system exceeds 20,000 operating hours, delivering stable year-round unattended operation.

Complete System Hardware Configuration
1)Main Control Cabinet Unit
The VS-PJ6100NM host cabinet features overall physical dimensions of 500mm × 410mm × 300mm, with a total net weight of approximately 50 kilograms. Each independent RF band outputs a single-stream radio frequency signal with maximum power no lower than 50 dBm per channel. Transmit power supports stepless adjustment from 0 dB to 30 dB in precise 1 dB steps, with adjustment error controlled within ±0.5 dB. All RF indicators fully comply with 3GPP standard specifications for spurious emission and intermodulation distortion to avoid interference with nearby public communication infrastructure.
Two universal power supply options are available: 110–220V alternating current mains power, or customized 28V direct current power input for off-grid industrial power environments. The maximum full-load power consumption of the complete main unit reaches 1800W, sufficient to drive full-band multi-sector antenna layouts for large-area coverage. The receiving sensitivity of the built-in signal capture receiver is ≤ -110dBm, enabling detection of weak mobile terminal signals at maximum effective distance.
2)Matching Multi-Band Directional Panel Antenna
Standard supporting antenna is a vertical polarization multi-band directional panel antenna, designed for pole mounting alongside the main cabinet. The antenna maintains a standard 50-ohm impedance with VSWR less than 1.5, delivering stable 15 dBi gain and 500W power capacity to match the host’s high-power RF output. Its intermodulation performance reaches below -150dBc to eliminate cross-band signal distortion, with a 7/16 DIN-F standard connector for lossless RF connection.
