CCTV Image Resolution and connectors
CCTV cameras that connect via a BNC connector have a maximum colour image resolution of 540TVL.
CCTV cameras that use an RJ45 connector, and are therefore called IP or Network Cameras, do not necessarily offer a higher resolution!
You need to check the spec – 540TVL approximates to 0.4 megapixel.
