Wireless video transmission from onboard cameras?

andypress · October 10th, 2006, 05:51 AM

I'm researching a transmission system for video for our 2007 formula-style (fsae) car that is currently being built. Even though I have done a fair bit of research, I have yet to come across what kind of systems f1 and other racing teams use to transmit video and audio from their cars. Any ideas?

hum, tricky one that.

do you mean to include telemetry data with the wireless stream too?

or do you just want multiple camera angles and sound?

what sort of image/sound quaility you after?

I'm no expert but I can ask around.

We do have a telemetry system that is capable of wireless transmission, but I'm pretty sure it can't handle the bandwith necessary. We would like something capable of one to two cameras with sound and a somewhat decent picture.

ok, I was meaning to ask what size track are we talking about and are there any under passes? I know that the TV people use multiple recievers based all round the track due to the bandwidth requirements with this technology, but they are monitoring multiple cars so your requirements will be much lower.

Out of interest what are trying to watch? are we talking just drivers view shots or are you watching the suspension systems?

The size of the track that we practice on is basically a mini suzuka that is .7 miles long. There are some trees but its mostly line of sight. Competitions take place on an autocross layout; so the tracks themselves are very small in comparison to regular tracks. We're trying to get a drivers view.

the big question is how much are you willing to spend?

andypress · October 12th, 2006, 03:04 AM

Really as little as possible since we don't have that much money to spend.

You could try something lik these.
Video senders. No idea on range though and they probs can't do multiple feeds

100 meters is kinda short for this, but we do have something like that in mind, albeit 300mw with a 3000foot range. Thanks.

right all my contacts were useless, but I did find these

15miles line of sight, but sounds like quite a bit of cash.

money will be needed to make a system worth installing.

i would first go with a pegasus video system:

(they have one-camera installs for about half the price)

the wireless transmission is the killer. to cover a track and maintain a decent video bandwidth, it will be expensive, and you would need access to the grounds of the track to set up relay antennas.

certainly you could try something cheap like x10's

but you have a 100 foot range (at best) and no sound, and pretty piss poor video quality.

i would definitely go with a bona-fide in car video recording system, and find a wireless system (eventually) that will work well.

Well, I contacted our camera supplier, and he said he'd be willing to donate some 1.2ghz trans/recs with a range of 3000 feet. Thanks to all who responded.
