This product is highly integrated and uses electronic jamming technology to implement precise countermeasures against drones within 500 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,...
The system are using a combination of day light TV and thermal infrared image sensor, steady continuous monitoring and tracking targeted drones.
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...
By jamming the communication channels, the drone is effectively disabled and forced back to its home base or grounded at its current location.
