I have a couple of Sharp 1/4" 420line CCD cameras and they're not bad for remote viewing, one is on my RC car (waiting for replacement bits again...), 1 lux min so they'll work ok in slightly dark conditions but not at night. If you're intending to put them on a plane be aware that the cases are metal, meaning that they're pretty heavy compared to plastic cased cameras but pretty robust.

The 2nd CCD camera you've linked to is less resolution at 350lines compared to the Sharp one you've linked, it might be noticable if you're recording at full PAL resolution but probably won't be if you're only going to be viewing the picture on LCD glasses. Being a board-only unit it'll be lighter than the Sharp metal-case one. Also note that it's NTSC only.

If size, weight and power consumption are critical then the Panasonic KX121 / KX131 CCD cameras should be looked at, they're very small and power from 5v, but can be expensive.

Thanks Haku

Yes, I did notice the 2nd one I listed was NTSC, but I had seen a PAL version somewhere; I think???
I am new to this CCD camera thing so it's a little confusing knowing whats good and whats not. Although it seems from what I've read lately, most people end up with the KX121/KX131, or use the Video/AV out on thier digital still cameras. This is also another option, but the downside to me is 1/ It's more expensive being that I would be buying a complete digital still camera, and 2/ it is bulky and much heavier.
I just watched some aerial footage taken using the KPC650 camera. The clarity/resolution is fantastic, but I guess it should be for $220usd.
I would like to see some aerial video shot with a KX121/KX131, so if someone can list a link, that would be great.

There are very high quality versions of these and others here if needed.

You've got a bit all of the possible conditions there, including night :P

Kilrah, thanks for the links. Seems the KX131 is a very good choice of cameras, and smaller, lighter, cheaper than the KPC650...

twinturbostang, FANTASTIC, that is one of the best/creative videos I have seen. The choice and placement of the music is spot-on, and like all good movies, the end is left open ready for the sequel. I almost forgot that the reason I was watching was to see camera resolution. Oh well, I better watch it again!!!!!

beaver: Thank you very much for the great comments. That's the best compliment I've received so far about the video! :) I originally put it together for the Aerial Video challenge on rcgroups.com. The theme was, as you can guess, "air to air". It didn't go over as well as I had hoped though. Another guy that got video of some Magpie's trying to tear his plane apart won. lol

Oh, as far as checking the resolution of the camera... the video link above has been compressed (obviously) and reduced in size to 480x360. My DV camcorder records in 720x480. The raw .avi files are simply amazing quality. But unfortunately, the videos have to be compressed/resized in order to send over the internet. The original .avi files are typically 1 to 2.5GB!! :o
