Annke L31V - i'm having a hard time finding much on that model number, can you share more pictures of the camera?
Annke carried a number of various camera's under it's brand - some really garbage, and others decent Hikvision OEM. If this is a hikvision oem model, you can look for hikvision cable wire colors. ( I think we have a few post on those here )
I've looked at the Hikvision pinout colours and none seem to tie in with the colours on the Annke camera. I've attached some photos of the camera im struggling with.
