Overview

Visual Smart Antenna System. Purpose‑built for complex urban environments including high‑rise buildings, urban villages, crowded squares, subway and transport hubs. Conventional positioning tools struggle in such obstructed, high‑density scenarios. This portable visual direction‑finding solution rapidly pinpoints target mobile‑phone bearings and positions, improving field investigation efficiency and providing law‑enforcement operators with intuitive visual‑based geolocation capability.

Workflow

Visual Direction‑Finding Workflow. The smart antenna unit receives cellular radio signals from target mobile devices. Real‑time bearing data is transmitted over WiFi to the local operation platform. The system overlays calculated direction‑of‑arrival information onto live camera video feed. Operators observe the augmented visual view to lock target bearing, capture screenshots for forensics, and complete on‑site localization without approaching high‑risk zones.

Highlight Features

Rapid Target Acquisition Capture and render target bearing & positional hints within 30 seconds for fast field response.
Strong Anti‑Interference Performance Robust operation for cluttered urban radio environments; starlight camera supports low‑light / night‑time deployment.
Light‑Weight Portable Hardware Compact ruggedized unit for field transport; real‑time visual monitoring via local operation terminal.
High‑Rise Floor‑Level Localization Resolves target to specific building floor, rendered on visual overlay for situational awareness.
Simplified One‑Button Operation Intuitive augmented‑video user‑interface, minimal training required for field operators.
Visual Forensic Capture Live‑video screenshot evidence‑taking and remote screen transmission for post‑mission documentation.
Remote Safe Operation Determine target bearing from stand‑off distance, protecting field‑staff personal safety.
Silent Passive Operation Receive‑only workflow, zero RF radiation emission during direction‑finding missions.
