Ah thank you! Now with that known, I can Google "IP Video Encoder" and a lot of information comes up -- it's good to know what I am actually looking for.
Wow, you are right though... a one port IP video encoder is almost $100! May as well buy a whole new IP camera for a little bit more. Darn, was hoping there would be a quick solution to get my system up and running until I can save money for an IP system.
Edit: Also, I was planning on running "new" ethernet cable to replace the Revo rj12 cable. Then the encoder would be close to the camera to convert from rj12/BNC to RJ45 ethernet.
