1. Introduction

With the rapid development and popularization of drone technology, drones have shown great application potential in aerial photography, agriculture, rescue, security and other fields, but at the same time they have also brought increasingly serious safety risks. Incidents such as illegal intrusions, malicious reconnaissance, and privacy violations occur frequently, posing serious threats to national security, public safety, and personal privacy. Therefore, the development of efficient and advanced drone jamming technology has become an urgent need to maintain airspace security and ensure social stability.

2. Device Overview

The portable FPV detection and video transmission capture device integrates detection, video interception, and video storage into one system. It features full-band detection, FPV analog video transmission detection, video interception, display control, and video storage functions. In complex electromagnetic environments, it can accurately identify quadcopters, fixed-wing drones, DIY models, and FPV drones, and provide sound, light, and vibration alarms. This device is suitable for scenarios such as routine patrols, critical target protection, unit-level operations, and investigation and evidence collection.
