KP-500TX4W is a -new wireless video transmission device, which adopts FM modulation mode and -new frequency, avoiding the 1.2Ghz/1.5Ghz/2.4Ghz wireless transmission that has been used more in the same range, avoiding the same frequency interference, and is more suitable for use in complex environments. The receiver sensitivity is -85dBm, and the transmitted image is clear and stable. With a ground high-gain antenna, it can transmit 2~3km in the open area of the city, and about 40km in the air-to-ground LOS (the transmission distance is different in different environments, and the specific transmission distance depends on the actual working environment). The transmitter is exquisitely crafted, made of special metal, and also has a high-speed fan, which is more conducive to heat dissipation and more suitable for long-term work. The signal input adopts a universal AV interface, which can be easily compatible with all conventional AV interfaces such as cameras, , , etc. KP-500TX4W is not
