I'm looking for a video camera to mount on my airplane.  This one is for sale

at a local motorcycle shop, and looks like a good choice.



	http://www.twenty20camera.com/motorcyclecamera.php



I'm interested in hearing from anyone with experience doing this sort of thing.

Is this a good choice of camera, or are there better options?  This camera has

a resolution of 400 lines, which sounds reasonable for NTSC video, but that's

purely a layman's opinion.  Am I going to get "TV quality" video from this

camera?

Seems like a bit of a rip off to me.  It is basically what the security 

camera people call a bullet camera.  They also include a mount, a 

voltage regulator, and a microphone.  You can get an line level output 

mic for only $10.  Since you already have an intercom in the plane, I 

don't know why you would want one.  You can make a voltage regulator for 

a few dollars.  Last but not least you can get just as good or better 

camera for around $150 or less.  If you don't want to bother with a 

regulator for the plane, just use an 8 cell battery pack.  AA NiMh or 

NiCd will both last plenty long.  The cameras normally come with a 

mount, but it probably wouldn't hold up under the vibration in the 

plane, it would be best to make your own. 



You can get these cameras in a lot of places just be sure you are 

getting a good one.  As that site you linked to points out there are 

some pretty crappy cameras out there.  I recommend looking for one with 

the Sony EX view electronics in it.  They have 480 lines Color  or 600 

for the B&W versions.  Just google for bullet camera and Sony EX view.  

Should find a lot.  You can get them in a wide range of lens sizes too.

Hi Tedd



I did a few tests with those tiny cameras and was always a little disappointed with the picture-quality they provided. They are quite easy to mount anywhere on the plane, though. 

If you want TV-quality, there is another option. By a small video-camera and build a mount. I tested my mount at 160 knots and the rudder input to compensate that additional drag is barely noticeable. 



There is a picture:

You need to be careful which one you buy.  Some are much better than 

others, most are complete junk.  Look for one that has the high 

resolution, 480 lines, like the Sony EX View.

Hi Thomas,

  

 Nice videos!  I have a couple of questions:

  

 How do you activate the camera when it is mounted on the wing?

 How far out did you mount the wing camera?  From the picture it looks like that the mounting bracket is removable.

 With your mount on the inside of the canopy, how much interference do you get from the prop and reflection of the canopy?

Hello Lothar



(at)How do you activate the camera when it is mounted on the wing?



It is actually a problem I have not been able to solve yet. Tape-recorders will not stay on stanby forever. They do switch off automaticly after a couple of minutes. That prevents the rotating video-head from damaging the videotape when it is not moving. The infrared remote control that comes with the camera has some trouble in bright sunlight as well. Some cameras have a wired remote or there is one available. I got one of these but I still have to make a longer wire. Right now, I start the camera on the ground during preflight. That gives you an hour.....



(at)How far out did you mount the wing camera? From the picture it looks like that the mounting bracket is removable.



Since the RVs do only have a small wingspan and it requires a wide-angle lens to have at least half of your plane on the video, I mounted it as far out as possible. Just half an inch away from the wingtips.

The bracket itself is removable. It will stay on the wing with a one layer of strong duct-tape. 



(at)With your mount on the inside of the canopy, how much interference do you get from

the prop and reflection of the canopy?



A lot. The reflecion of the canopy is the worst by far though. It depends on the direction of the sunlight and the time of the day but sometimes there few useable minutes of video on the tape. I thought about getting a polariser 

but I have no idea how much it actually improves things here.
