This is a -new wireless video mission device, which adopts FM modulation mode and -new frequency, avoiding the 1.2Ghz/1.5Ghz/2.4Ghz wireless mission 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 mitted image is clear and stable. With a ground high-gain antenna, it can mit 3-5km in the open area of the city, and about 50-60km in the air-to-ground LOS with high gain antenna. (the mission distance is different in different environments, and the specific mission distance depends on the actual working environment). The mitter 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. Different batches may have different appearance label printing, which not affect the use Colour:Silver Material:Aluminum Alloy Package Contents: 1 x mitter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
