I am not sure if this is the place to post this type of question. If it is not I will delete.

At present I have 4 analogue cameras 'talking' to my DVR.

I want to unplug 1 of these cameras from the DVR and connect it directly to my PC. Is there a typical analogue to digital converter I can use?

The analogue cables endpoint is a balun.

If this is not the correct forum then I would be grateful to be told what is the correct forum?


  • There's not enough information here. What sort of PC? Is it running Windows, OS X, Linux, or something else? Is the camera standard def or high def (or something else)? Commented Apr 17, 2015 at 2:46
  • @user1118321 Hi thanks for showing an interest. The PC is windows 7 64bit. The camera is analogue CIF Commented Apr 17, 2015 at 8:16
  • Unfortunately, I know nothing about CIF, so I'm not sure where to point you, but hopefully the additional information will improve your chances of getting an answer! Commented Apr 17, 2015 at 15:43
  • @user1118321 indeed. thanks :) Commented Apr 17, 2015 at 15:44

1 Answer 1


You need a video capture device or a capture card. It will encode the analog video and audio into digital codecs (like H264 for video and AAC for audio, or other codecs depending on your needs and price range).

  • Hi, thanks for your answer. I knew I needed a video capture device but after searching myself through Google (before you posted your links) I could not find 1 for this specific case where the cable endpoint is a balun Commented Apr 25, 2015 at 6:38
