lost picture (on Vera) of FI9805W

I had my FI9805W working fine for a while. I have changed nothing, but al of a sudden i cannot get a picture on the Vera device any more, nor on Authomation. When i access the camera via Firefox (local or via DDNS) its working fine. I have not updated firmware or changed any settings. My other cameras are working fine. Tried to recreate the camera device on Vera, but again, no picture. I have no idea what to try next.
My camera:

Camera Model FI9805W
Camera Name FI9805W
Camera ID XXX
Camera Time 2014/08/02 10:01:28
System Firmware Version 1.4.1.9
Application Firmware Version 2.14.2.8
Plug-In Version 2.0.2.10

Why did I not try that earlier… power cycle did it. All working again. Well actually picture has just gone again after only a few hours, so will probably put a module on there to be able to remotely power cycle it. Not sure why that happens, my other cameras work fine for months

I thought power cycling solved the problem. It does temporarily. But after a few hours the picture the problem is back and the picture gone. The camera is connected wired
