Cameras can be powered via POE (power over Ethernet) which means the cameras send data and power over inexpensive Cat5e/6 cable. One cable to do it all. Video can be sent directly to a web-based service to view/save video or to an NVR (network video recorder). The recommended choice of systems for a new install.

Analog uses RG-59 or RG-6 cable.
RJ49 is a telecom wiring pinout for twisted-pair cabling.
Analog video isn't tried and true, it's dead. IP has long since overtaken analog for any new install, it's not up and coming.
If anything the up-and-coming alternative to analog would be HD-SDI or HD-CVI , which lets you usually reuse those old analog cables to make a closed-circuit digital camera system with resolutions that match the lower-end of the common IP camera range (720p or 1080p).
Web-based recording isn't feasible for any decent resolution or frame-rate for real time recording, but it can be used for snapshots or offsite backup of *selected* portions of video.
