Well, with everyone wanting one, why are there not any manufacturers already making a RC CAM?
There are several sources for ready-to-use systems. The vendor links forum has some resources. Yb2normal, a helpful long time RC-CAM site member, sells them too and he has good stuff at fair prices. There are other quality vendors out there too. On the flip side, the market is sadly buried in cheap Hong Kong imported junk, sold mainly in venues like eBay.
However, wireless video for R/C may never be mainstream because there are a couple of hurdles. First, the systems {that work well} require a ham license to operate legally in most countries, including the USA. Secondly, this is microwave based RF. So, not matter how hard a vendor tries to make this plug-n-play, it just never will be that for everyone. The installation and operation requires an attention to detail and some RF knowledge goes a long way.
Everyone here seems to be a project man, tinckering with this and that, there has got to be a ready to use system out there compatible with the RC market.
That is the exact purpose of this site. RC-CAM is a technical resource. Mainstream stuff and out-of-box solutions really don't serve the focus of what is going on here. For that, you can go to all the other R/C forums and avoid the technical discussions (and perhaps not learn how to make wireless video systems work its best).
Real fustrating hearing that this video camera and transmitter go together and then finding out that you have to make all kinds of mods to it because of either poor video quality, not enough distance or just plain does not work because of interference.
Again, that is the nature of the microwave RF beast. Plus, it doesn't help that many vendors use CMOS cameras instead of CCD. Some print bogus specs (and even when they do publish real data, the average Joe will not know how to interprete it).
Here is a basic plan I recommend to those interested in R/C Wireless Video. First, get a ham license. You need technician class. Cost is free, or nearly so. Details are at www.arrl.org. Next, buy a system that includes a good CCD camera and is 50mW to 200mW of REAL RF power that operates on a ham legal 2.4Ghz freq. Lastly, use the knowledge you gain in studying for the ham test to help ensure a good RF installation of the equipment. And expect to tinker. Cost? If you are a DIY'er and don't mind soldering some connectors and building a regulated airborne power supply, then budget $250. Otherwise, budget twice that for a ready-to-install system.
If all that sounds like too much work, then you can always go another route. Lightweight digital cameras can be used too. They take stunning photos and many can also record videos. The
RC-CAM Projects Page has links to CamMan, a very popular DIY project for controlling the shutter on digital cameras. Or, you can glue a servo to the camera and trigger it that way. R/C sites like eZone have plenty of information on how this is being done by the average R/C'er.
R/C wireless video is a blast and worth a little effort.
