Overview

Active Geofence Tracking System. This zone‑bound active collection system gathers IMSI, IMEI and other identifiers from mobile handsets entering the geofence area. It accumulates spatial‑temporal electronic traces of population movements. Collected datasets feed case‑related investigation workflows, especially for monitoring criminal suspects’ regional activities, providing reliable data foundation for investigative‑department technical operations.

Highlight Features

High‑Covert Deployment Supports disguised installation, anti‑reconnaissance capability for concealed field‑site operation.
Non‑Intrusive Quick Release Captures identifiers then immediately releases terminals back to public network without disrupting subscriber services.
Multi‑Network Full Compatibility Covers 2G/3G/4G/5G‑NSA and mainstream carriers, supporting wide‑range identifier acquisition.
Auto‑Public‑Network Adaptation Automatically scans surrounding cellular environment and configures operating parameters without device restart.
Big‑Data Track & Heat‑Map Analysis Mass‑data retrieval, trajectory reconstruction; visual heat‑map output for regional‑activity statistics.
One‑Click Associated Query Input phone‑number / IMSI / IMEI to perform multi‑dimension associated analysis and target‑profile rendering.
Flexible Data Transmission Both wired and wireless transmission options; supports early‑warning, data collision and background storage.
Integrated & Stable Hardware Integrated unit for simple installation; stable runtime performance with low maintenance overhead.

Working Principle & System Characteristics

Geofence Collection‑Analysis Mechanism. Front‑end sensing equipment actively collects mobile‑terminal identifiers from devices inside coverage. After brief identifier capture, handsets are quickly handed back to operator public network. Raw data is transmitted via wired or wireless links to the big‑data platform for persistent storage. The upper‑layer intelligent policing platform delivers core system capabilities: track‑retrieval, accompanying‑analysis, early‑warning notification, equipment O&M and case‑management. The system regularly computes historical records to build movement trajectories, supports statistical comparison and heat‑map visualization for regional crowd‑activity monitoring.
