I have a 690TVL Ultra WDR Pixim SEAWOLF HD CCTV Mini Camera  2.8mm Lens OSD this is on the net for £50 ish. Fantastic picture but if you need a mini cam probably no good. The problem is none of the individual manufacturers want to take responsibility with each saying it's the others product. My video guru club mate is a retired bbc engineer and he said it's either the power module or incompatible voltage regulators in the vtx and camera. It is much better With the separate battery to the vtx. I have 2 models exactly the same spec except the camera. The seawolf is by far the better. One thing though. Make sure you have a common earth  for the camera and vtx. Or power cam and vtx from same external battery or it won't work, of course osd vid volts will be wrong but it is anyway. I wondered if it is the same with a 5v camera and step down? Or a different vtx. Must be some reason why some users don't get it. Btw have you removed the red lead from your ESc? I have not and it does not seem to make any difference.

Hi Tim,

Many thanks for that info sorry it's taken a while to get back to you.  I did as you suggested and tried powering the vtx from a seperate batt which as you said eliminated most of the lines.  I also tried powering the camera direct from the balance port of one of the 4cell batts , through an lc filter which seemed to make for a big improvement too. (on the kitchen table)

I took it out yesterday for a quick test without the expected result.....

Think I will have to find a place to fit that seperate lipo .

The camera is giving pretty poor results, so I'm going to try the mobius as an fpv cam, as you say, maybe a cam on 5v will help.

I did remove the red wire from the esc on my fy41 - sound like maybe I needn'thave bothered.

Thanks again

Mark

Looks like you have a few issues there, see the top of the picture starting to curl in, that`s normally down to your video signal level. Normally fixed with a 100 ohm resistor.

Either placed between the video signal wire and the ground of either the camera the OSD video output
