Wireless output to monitor idea

Kris Koster · January 31st, 2011, 03:29 PM

Since my new purchase of a Kessler crane and having just finished production on a music video with it, I've been trying to think of easier ways to view the sets on a monitor without ugly, draping wires getting in the way.

I just saw this product: http://promos.asus.com/US/Newsletter...ead_Story.html

Wireless transmitter and receiver of full 1080p video? I know the product is intended for transmitting from computer to TV in living room but... Hmmm. I'm wondering if this technology could be adapted to work with the 5D mark II output to monitor. If it did, it would be incredible.

Obviously it's a solution that won't work, or other people here would be raving about it, wouldn't they?

I guess you've got to define "won't work."

I'm sure when you turn it on, you'll get a picture.

The key is that when you start swinging the camera around, will you MAINTAIN a clear, viewable picture, or will the constant changes in transmitter to receiver distance and angle - or any lack RF carrier instabilities or the like cause the relatively cheap circuits involved to start tossing garbage at you?

I always notice that on the remote video send/receive units that are used at the big political conventions, it's almost GUARANTEED that at some point during the critical interview, the signal will fall apart momentarily.

If that's the fate of MULTI-THOUSAND DOLLAR top of the line pro gear - what's the best YOU can hope for with something costing many, many times less.

When in doubt, a cable is a thousand times cheaper and typically a thousand times more reliable.

And if it starts to mess up, you can grab another and fix things.

Good luck.

Don't go near any microwave ovens. They will kill a 5GHz signal at 100m!

going wireless is the typical false good idea.
at first glance it iseems to resolve problems, but once in production it often bring its own share of annoyance

first, you will need to supply 5V 2A power to the transmitter, so if not on battery (heavy at the top of a crane, you will then need a cable , yes exactly what you were supposed to get rid of, to power supply it.

then, you will need the same at the other end for receiver.
Then you will get problem with transmission.
and anyway, except if you get a 7D, all other canon DSLR are just outputting SD, so no need to purchase anything using hdmi or claiming HD, a cheap 2.4Ghz chinese video transmitter will fit.

you can find very thin and light coax cable (usually found on wifi equipement), for $5 and get sure to have the best quality. look for RG174/U cable or 178 or 179
you can find this cable as low as $1 per meter
