The all-in-one FPV GOGGLES with build- in A/V FPV receiver and virtual real-time large-screen display can connect with the RC FPV Transmitter with a data cable, RC fpvTransmitter supply power to the AIO FPV GOGGLES.

Along with the AIO FPV GOGGLES tracking signal output to the RC Fpv Transmitter, the AIO FPV GOGGLES tracking signal and the RC Fpv Transmitter control signal received by the receiver in the RC Aircraft. Images and sound captured by Camera are transmitted to the sky by the A/V Transmitter,Then,AIO FPV GOGGLES can receive video and audio within a certain range, people who wear an AIO FPV GOGGLES can see the images from the virtual real-time large-screen display, and hear the sound from the earphone.

Features of fpv goggles:

The new SkyZone FPV goggles features front camera, higher resolution screens and diversity receiver. 
These goggles have some ground breaking new features not found on other goggles. The build quality is very nice, the screens are crisp with clean edges and have a resolution that is higher than most. 
The Benefits of fpv Goggles with Diversity 
A diversity system uses two different video receivers, and two different video antennas. This gives you a better chance of receiving a clean and unobstructed signal. These are connected by a diversity unit that chooses the best video signal. You could mount one of the stock antennas vertically and one horizontally. For best results you want to use different types of antennas. This gives you the option of using a long range directional antenna for one receiver and a non-directional antenna for the other. The diversity system automatically chooses which antenna is receiving the best signal at any moment. 
Front Camera of fpv goggles 
The 640x480 front camera was added to allow you to do things without removing your goggles. When you have to pull your goggles off you have the issue of your eyes adjusting to the external light. You also have to physically remove the goggles or situate them on your head so they don't fall off. The external camera allows you to keep the goggles on for small jobs and landing. The lens on the external camera does seem to make things look farther away. 
5.8 Diversity Unit of fpv goggles 
These goggles have a built-in 8 channel/4 band 5.8G diversity unit. This allows you to use this unit with most FPV 5.8G transmitters on the market like Foxtech, DJI, Walkera and more. 
Dual Receivers & Dual Antennas fpv goggles 
There are two 5808 receivers in this set of goggles. 
The unit comes with two vertical omni stock 50ohm antennas with sma connectors.
Monitors 
The goggles have dual 854X480(WVGA) monitors with 1,229,760 color sub-pix 

Head Tracking of fpv goggles 
These goggles have built-in self calibrating head tracking that utilizes a gyro. 
-PPM Channel Setup
-Pan Tracking Range Setting
NOTE - If you use the Futaba trainer plug you can power the goggles that way (no external lipo needed). 
Lipo Powered of fpv goggles 
A nice feature with these goggles is that just about any lipo you have can power them. The input power plug accepts voltages of DC 7- 28v/1A. I find that a two or three cell lipo does a good job.

FOV (Field of View) of fpv goggles 
The goggles have 30 degrees (diagonal).
