«Chuika 4.0» is a four-band portable drone detector designed for detecting analog video signals and identifying UAV signals in real time. «Chuika 4.0» is a personal device that operates fully automatically, requires no additional configuration, helps users respond to threats in advance, and enhances protection.
The device is equipped with 4 antennas, 2 screens, a video output for connecting an external display device, and a connector for an additional or continuous power source.
Functions of the «Chuika 4.0»
- Analog video signal detection. Operates in four frequency ranges: 1080–2200 MHz; 2860–4500 MHz; 4860–6040 MHz; 6040–8800 MHz.
- Extended radio spectrum scanning. The additional fourth antenna covering 6040–8800 MHz provides monitoring of a wider frequency spectrum and expands the device's UAV activity detection capabilities.
- Additional power connection. A separate input is provided for connecting an additional or continuous power source, expanding the possibilities of using the device in stationary and mobile scenarios.
- Fast frequency range scanning. A complete automatic scanning cycle takes 4–8 seconds.
- Visual and audible warning. When activity is detected, the device provides audible and visual alerts, warning the user about a UAV.
- Data visualization on the screens. The small screen displays the level and number of detected signals, while the large screen allows the intercepted analog video signal from an FPV drone camera to be displayed, just as the operator sees it.
Operating Principle of the «Chuika 4.0»
- After being switched on, the device performs automatic calibration and begins parallel scanning of four frequency ranges.
- The device detects active channels, analyzes the presence of an analog video signal, and displays the data on the small screen.
- If a corresponding signal is present, the user can view the intercepted video on the large or an external screen.
The detection range depends on the frequency, video transmitter power, antenna type, presence of interference, terrain, and other operating conditions.
