CCTV noob

Recently got a Samsung "home security" bundle that includes a monitor, a "video processor", 4 cameras, and 60 ft cables refered to as "rj11e" with 6P6C rj11-size plugs. The cables carry video, audio, and power to the cameras (12V DC). The monitor connects to the concentrator with a UTP-like cable with rj45-size modular plugs. Wish I knew more.

What exactly is rj11e? Is it a standard scheme in home security? Is the cable UTP? The documentation says it's "shielded". Do they mean as in STP? What are the distance limitations? Could I extend it/adapt it to the UTP wiring and jacks already installed in the house?

Sorry about all the questions, this has picked my interest. Any info, or relevant links would be much appreciated.
