The drone RF detection and jamming integrated machine ZD01 is a product developed for small areas such as detention centers, stadiums, and villas. The product can realize rapid deployment in fixed areas, realize automatic detection, and automatically suppress the integrated 24-hour unattended ope...
The No-fly zone device is mainly aimed at GPS/GLONASS/BD navigation systems, launching false satellite navigation signals to form a no-fly zone function, and drones cannot fly into the no-fly zone. The device has low radiation power, has no effect on the surrounding electromagnetic environment, a...
SC02 is an upgraded version of SC01, which implements precise countermeasures against drones within 1000 meters. Multi-band electromagnetic emission, ready to use, cuts off the remote control, image transmission, and navigation links of the drone at a long distance, thereby forcing the drone to l...
HANVYADG is a hand-held, anti-drone gun that can disable drones operating on 5 frequencies and has a range of up to 2,000 meters.
he Passive RF Detection system analyzes and identifies the remote control signal and data return signal of drones, detectes target and early warning
