I would like to be able to record 5-8 video channels on a linux computer.

While the videos are being recorded I would like to break them into 1-2 hour pieces and back them up.

The source of videos is 24/7 for a few days and I cannot afford to lose video.

I have seen a number of solutions but standard security cctv DVRs/NVRs tend to make you use their software to download video files (even if you try to back the video files up on a NAS).

Are there other possible solutions to this problem?

RCA to USB connecters can only be recorded one at a time (I think) and certain frame grabbers tend to record uncompressed video which would be too computationally expensive to encode when it's a multi channel feed on a single linux machine. Nvidia might be able to encode videos fast but I'm not sure how many channels of raw video it can do at the same time.

  • @Mokubai I have re-worded the question, please do see if this is better :)

  • Suits me fine, your original question might still work on Hardware Recommendations though.

  • What exactly do you mean by "A/V" and "video"? Do you mean CVBS composite video, which is low quality and old tech? Modern cameras have embedded microprocessors, and digitize, encode, and compress the hi-res video into a data stream (e.g. IP cameras). "RCA to USB connecters..." -- A nonsense description. RCA connectors can be used for analog audio, or digital audio, or composite video, or component video. Specifying only the connector type instead of the proper signal name (and omitting the functionality of the device) is usually a sign that you don't know what you're doing.

  • Sorry for not being more specific, I've only been doing this for a few months with no progress. Yes I mean CVBS composite video, the source of video is a set top box. @sawdust

  • "the source of video is a set top box" -- So you have a stack of 5 to 8 STBs?
