IP CCTV cameras are more advanced than other formats as each camera is technically a stand alone network device, as well as the recorder. This means cameras can be logged into directly to manage settings, some have wifi built in and/or limited on board SD card recording and don't need the NVR recorder to operate.
IP CCTV can save a lot of wiring also where an existing network infrastructure is in place (CAT5/6 cabling throughout an office block or home for example) and support POE (power over ethernet) when plugged into a POE switch/NVR or injector so to provide the data/video connection and power down the one CAT5/6 connection.
The biggest selling point though is the ever increasing resolutions with 4+ Megapixel cameras and cctv kits coming as standard now, with high end cameras reaching a staggering 29 megapixels!
