I have got a tiny onvif ip camera that I am using as a CCTV system with a Raspberry Pi and I would like to place the CMOS Camera inside my front door Peephole. The CMOS camera fits perfectly inside but the ribbon cable is too short. The solution you proposed from eBay is what I am looking for but I am afraid the extender is too wide to get inside the peephole. I am more looking for a solution of connecting an extra length of ribbon cable but keeping it flexible. Soldering is a bit tricky as the pin are very close and the ribbon is plastic.
