Networked Handheld Detector Closes the Low-Altitude Law Enforcement Loop
2026/07/09
DJI Mavic 4, Mini5 Pro, Autel EVO Max 4T and modified multi-band FPV drones create growing airspace security risks at airports, prisons, power plants and event venues.
Legacy single-point detectors suffer limited coverage, poor pilot positioning accuracy and missing intercom & evidence tools — slowing team coordination, on-site investigation and closed-loop law enforcement, especially during multi-drone swarm incursions.
Equipped with a broadband RF receiving architecture, the detector covers a full frequency range of 70MHz to 6GHz (Evidence: Product Specification Document), supporting all major bands including 800/900MHz, 1.2GHz, 2.4GHz, 5.2/5.8GHz and Wi-Fi. It is fully compatible with all DJI series, full Autel lineup, various FPV racing drones and custom modified aircraft.
It achieves a detection distance of up to 3km in open environments with a response time under 5 seconds and a detection success rate of ≥99%. Capable of tracking up to 15 swarm drones simultaneously with a positioning refresh rate ≤2 seconds, it maintains stable capture even during multi-drone incursions, drastically reducing missed detection rates.
Fitted with a 6-inch touchscreen, the device uses passive signal direction-finding algorithms to deliver positioning accuracy within 3 meters (Evidence: Product Specification Document). The electronic map displays real-time coordinates of both drones and their remote controllers, with one-click navigation to guide officers directly to pilot locations for rapid on-site handling.
The device reads complete drone information including SN serial number, model, altitude, speed and flight trajectory. The blacklist/whitelist function automatically mutes alerts for registered compliant UAVs. Built-in trajectory playback and historical record storage retain all detection data, providing a complete electronic evidence chain for law enforcement.
The whole unit weighs under 580g without antennas (Evidence: Product Specification Document), ergonomic for single-hand portable operation. The built-in lithium battery delivers 3 to 4 hours of continuous runtime with the screen on, and supports charging while in use. The device connects to central management platforms for multi-unit networked collaboration across large-scale prevention scenarios. Built-in wireless intercom enables instant communication and coordinated operation across multiple devices under unified command, eliminating information gaps during team patrols.
Multi-band modified, swarm and scattered rogue drones render single-point detection insufficient for modern airspace supervision. This upgraded handheld terminal delivers 70MHz–6GHz full-band coverage, 3-meter precision positioning and multi-unit networked intercom for all DJI, Autel and FPV UAVs. One device handles the full detection-to-evidence workflow, while multi-unit networking builds area-wide collaborative defense for airports, prisons and large events as a standard public security tool.
