Sb87

I have a swann NHD 875er poe camera this idiot didn't seal the connector properly and moisture got in and damaged one of the pins (it's black). I know I've not fried the camera as it powers on before going off and it I wiggle the cable it does keep doing this. So I need to replace the tail but I can't find a swann specific one with 8 leads most of um have 11 Anyone any pointers were to find one or someone that repairs them professionally in UK
