Analog cameras are more traditional cameras that transmit video over coaxial cable to a DVR (Digital Video Recorder). IP security cameras transmit the recorded video to an NVR (Network Video Recorder) in the form of digital signals by using Cat5 or Cat6 ethernet wire and a PoE switch. This eliminates the requirement of power cables that are needed on Analog systems. The image quality and frame rate is higher on IP cameras which makes them more ideal, especially for areas that require greater detail or that have a lot of motion. IP cameras can cover more area than Analog cameras so less cameras could be needed for the property. Analog cameras are not encrypted, which means a hacker could potentially access your information but IP cameras are encrypted, making them more secure. The number one reason to get an Analog system over an IP system would be the cost as they are significantly cheaper than IP camera systems. Although, it is recommended to stick with an IP security camera system as the advantages far outweigh those of an Analog CCTV system.
