Best solution for Analog CCTV over ethernet in General Analog CCTV Discussion Posted January 22, 2015 Either that, yes. Or, an IP camera over ethernet/IP to a decoder that output analog video to the DVR would work as well. However, I believe IP cameras will drastically increase the cost? I just want to make sure I get this right before I put my foot in my mouth. Basically you want to utilize/connect your analog cameras as if they were IP cameras; hence the need for encoders and decoders?
