Swann CCTV DVR

[ppppenguin]

I don't understand why you would have to change the cameras. New CCTV DVRs can take more modern high resolution security cameras but should default to ordinary video if that's what's being fed to an input. It's only recently that I found out about AHD and TVI, two methods of sending high resolution analogue video over standard co-ax. I haven't looked at what kind of technical wizardry they use to do this.

The most modern security CCTV kit uses digital conenctions with PoE (Power over Ethernet). Each camera just needs a standard Cat 5 (or better) connection.

Unless there is some very good reason to keep it, the old DVR is scrap. It has to run reliably 24/7 so there's little point in reviving an old and ailing unit.

PS: Just found this, comparing the various HD analogue technologies. https://shopdelta.eu/test_l2_aid752.html
