FPV drone video transmitter is a sensitive device
HD FPV drone video transmitter
HD video transmission is a relatively new technology for multi rotor, which can definitely improve the overall experience of FPV. The standard camera / vtx combination, while not lacking in detail, sends and displays video in a standard definition format, usually at about 600 TVL (TV line) or 768 x 494 pixel resolution. On Google monitor, this resolution works well, but if you want to enlarge the image on a larger monitor, it may leave some undesirable places. HD video transmission is like this. They operate at 1080p or 720p resolution, bringing more life to your FPV feed. There are some systems, but when you look at them, you want to make sure that you are using a low latency system, because even a few milliseconds of extra latency in your feed may be the difference in your response time to obstacles or doors.
Other features of FPV drone video transmitter
Microphone - some vtxs have built-in microphones to send audio to pilots. Some pilots like this feature because they can hear what happened to the engine and props, and can hear any problems, such as the tone, or parts that may not work properly.
Smart audio - a new feature of FPV world is smart audio. This allows you to control your vtx's power output, frequency band and channel from your goggles or transmitter, allowing you to change options in flight rather than using onboard buttons or dial switches. Absolutely a useful function!
Power filtering - there is a lot of current flowing through multiple rotors in the air, which can cause some dirty power to flow through your FPV device. There are several vtx vehicle power filter systems on the market, which can remove the power before the power reaches the transmission end to reduce the static interference in the video signal.
Pit mode - this is a useful feature that allows you to start your FPV drone video transmitter in an extremely low power mode, which allows you to change your band and channel without interfering with anyone currently in the air. In this mode, the transmission range is limited to a few feet without causing any problems to other people at higher power levels.
Thermal protection - some vtx have the ability to limit power output when heat rises, preventing you from burning your vtx while it is stationary on the ground.
Remember, the FPV drone video transmitter is a sensitive device. It is strongly recommended that you do not Repeat, don't turn on the vtx without the antenna. The only purpose of these devices is to transmit video signals to the world. They are realized through antennas. When there is no antenna connection, the signal has nowhere to go, which can cause your vtx to cook itself and release magic smoke... It doesn't smell very good. So don't do that.
