Network Cam Capture Method?

I currently use analog box cameras with an analog to digital capture device via USB. I have been looking into IP cameras that go on my network and I have a question.

Do network cameras have their capture device built in? This seems like a better solution to bottlenecking these box cams: digital cmos > analog output and cable > analog USB capture device > back to digital.

With network cams I assume it is: digital cmos > digital capture > digital network output?

A network camera has an ethernet interface, so yes it's digital. And many of them are also powered over the same ethernet cable. They can plug right into an existing LAN.

Thank you, I just saw a video explaining the answer I needed. All the encoding is done right in the IP camera itself.
