Project

I know we've already had the "which in-car camera" threads, so I thought I'd go with something a little different. I already have the camera, but was wondering if anyone had had any experience with streaming the footage wirelessly, say, to a big screen on a rally spectator stage.

I think the issues to bear in mind are power, legal frequencies and the Radio Authority. Broadcast microwave kit isn't cheap.

Yes - its expensive and difficult to get right.

as above.

we use a small microwave transmitter/ reciever at work, to wirelessly monitor steadicam footage. - it has a max range of 20 metres, and suffers from quite a bit of interference


For what your talking about, youd need something very expensive- even hire rates will be pricey.

If your serious about it, have a talk with the guy who runs this site:

his named slipped my mind at the moment, think its neil, but i worked with him a few years ago ona project- he's done all sorts with cars, mini cams, and microwave transmitters.

When the mercedes mclaren slr was first released, mclaren invited potential customers to see it demo'd around a track, and he rigged up the car with a transmitter and several minicams, mixed picture in picture, to be shown on a plasma screen for the clients to see

I don't have any intention of buying the equipment, I probably should have mentioned this earlier. Its just an idea for a project I have to do. I need to research the kind of equipment used, how it works and pricing etc.

Try this lot.
Had one on a kart recently, it wasn't that bad!

how it works

That's easy in principle. Camera is connected to omnidirectional microwave transmitter. That beams the signal to a microwave receiver (either omni or unidirectional with bloke holding it) and that's connected to the screen and/or recorder. If you watch sports events like F1 you'll see a thing like an oil filter sticking up from the back of each roving camera - that's the transmitter. But power and reception is critical and affected by humidity and rain. Added the the fact that microwaves are a bit weird (preferring to travel around wires rather than through them), it all gets very expensive.

Hence it's much easier to record on-board and edit/watch later!

Thanks, that site is really useful, got a lot of tech-specs for range and power etc
