Portable drone detection and jamming equipment for event security

This portable anti-drone jamming device is designed for security of large-scale events, protection of VIPs, public space protection, and temporary emergency deployment. The device incorporates a high-efficiency multi-frequency jamming module that can accurately block common drone control links, including GPS, BeiDou, GLONASS, and wireless remote control signals, achieving navigation interference and positioning paralysis for drones. By actively blocking the drone's satellite positioning system and flight control signals, this device can force drones to return to base, land, or lose control, effectively preventing high-risk activities such as surreptitious filming, data theft, dangerous drops, and illegal reconnaissance.

The entire unit adopts a highly integrated industrial structure design, is lightweight, comfortable to hold, and can be quickly deployed by a single soldier. It is widely applicable to sensitive areas such as concerts, sporting events, exhibitions, borders, reservoirs, power plants, airports, and VIP security. Whether for mobile duty or fixed surveillance, this device can achieve second-level response and full-area coverage, becoming a core countermeasure in an efficient security protection system.

The equipment adopts omnidirectional passive wireless detection and intelligent algorithm collaborative technology, enabling 360-degree real-time monitoring, identification, and trajectory analysis of UAV signal sources. The system can identify multiple models and frequency bands of UAVs and determine their flight purpose and status. Through its spectrum analysis system, the device can detect the takeoff, approach, and hovering trajectories of drones, automatically assess threats, and output early warning information.

Regardless of whether the drone is in motion, hovering, or in stealth flight mode (such as low-altitude slow flight), it can be quickly locked onto and tracked. Users can establish a mobile air defense monitoring network without additional radar or fixed guard posts, meeting the needs for temporary security blockades and rapid response in large-scale events such as concerts and political meetings.

This device integrates a high-definition real-time monitoring display screen, allowing users to directly view the drone's signal strength, type, location, and warning level on-site, eliminating the need for connection to mobile phones, computers, or external terminals. The system interface uses a simple graphical operating logic, supporting functions such as language switching, warning recording, historical playback, and data export.

The screen synchronously displays a spectrum graph and interference coverage area, facilitating accurate assessment of interference effects by security personnel and enabling an integrated security process of detection-judgment-response. Even in complex electromagnetic environments or densely populated areas, operators can quickly grasp real-time threat information, improving work efficiency and safety.

The device is optimized for jamming common drone data link protocols, effectively disrupting the drone's WiFi control link, image transmission signal, and wireless remote control command (RC Link). Through directional jamming, the device can render the drone without control signals, immediately halting its camera, live streaming, or data acquisition functions, thus preventing it from continuing its flight mission.

This function is not only used for counter-espionage, counter-reconnaissance, and counter-aerial photography, but also serves as an electronic air defense barrier in key areas, effectively blocking malicious drones from threatening personnel, facilities, and information. For police, military, emergency response units, and security agencies, this device is an important tool for building a low-altitude security system.
