Help with remote in car camera transmission to pits

[KangarooMike]

I recently watched a video where the host mentions that they have a camera mounted in the car and transmits video to the pits. They mentioned that it was a modified FPV done camera transmitter in the car and it goes to a receiver in the pits that goes to a screen.

I have little to no knowledge when it comes to wireless data transmission so I need some help

I would like there to be an HDMI input in the car (to attach a gopro or other camera) and then an HDMI output on the receiver to display on a monitor in the pits.
The car is in development at the moment so we can add large antennae to it if required

A bonus would be if I could get an audio feed as well

So this has many options...They range from DIY to pricey

Now this is a race car obviously, so transmission of clear video would be needed for any purpose (sharing, reviews, error detection)

Just remember on a track there are multiple other monitoring sensors and transmission bands in play, so be cautious. They should never interfere but just mentioning.

The cheapest route to entry would be a webcam with a mount + laptop and a 4g/5g connection streaming the feed to the pit. If you don't have someone who understands video streaming and the complications around it or not buying a pre-made kit do not attempt this as it is a costly exercise to do accurately.

On a much smaller scale, I had an OBD reader that had WIFI support, and an old phone with good camera. My rig was temporary, to make some fun car videos with stats on the car being fed. Had a mifi hotspot, and the footage was stitched together after. That is usually a very easy-to-do thing. Streaming that feed with fidelity to my knowledge is complex.

I would use the 4/5G way but Red Star does not have coverage for 70% of the lap. The range would need to be around 2K with line of site.

In terms of radio bands, it is on farm land so not too much congestion other than the radios that the marshals are using.

I have some limited knowledge of video streaming but it is limited to streaming to platforms such as twitch

You know this my suggestion, maybe someone more knowledgeable is around on this forum who has a solution that is more straightforward. However should you not come right by whatever your deadline is, PM me, and I will assist you with some solutions after gaining some more info.

So when I mention streaming, I mean you need to understand streaming from the end of Twitch since they deal with the technical challenges associated with live streaming.

You could very well buy a cheapie setup that gets the job done, then you will find it cuts off at certain areas, drops quality, and has choppy video. Which long term would never scale, especially if you are considering building this into/within the car.

JUST FOR CLARITY - I AM MENTIONING THIS
FACTORING BELOW
A - High Fidelity Video
B - Real-time feed
C - Environmental Challenges (Rainy Days, Wind, Heat)
D - Distancing is not static so adequate transmission overhead to be allowed (unless you do this racing at 1 place always)

And you need to maybe put a max spend on this... since videography/photography is a pricey game in itself let alone with the other aspects of this project.
