I've been wearing VCRs out from recordings on my security camera. Getting tired of replacing them so I looked at DVRs. I'm a little confused about them and not sure just what I need for the camera. They talk about TVs and subscriptions but I don't need all that. The camera (Swann) have the A/V cable with phono plugs so the hookups wouldn't be a problem.

Anyone know what I'm looking for?
