Hi guys, hope you can offer some advice. I have moved into a property with four cameras, one is a bullet iqcctv hd960h.

Unfortunately the previous owners cut the cables going to the DVR and I have no idea how to crimp/repair. 
 

I have attached a picture, the black cable contains one yellow cable with copper wrapped around and a red cable. Is this BNC? I presume red is power and yellow is video as I can’t see any separate power leads..
 

Can anyone help with advice on how to fix so I can connect to my DVR please? 

Thanks for your help guys ??
