Analog CCTV (Closed-Circuit Television) and IP (internet protocol) CCTV Systems are two types of Video Surveillance Systems used for monitoring and recording activities in various environments.

Analog CCTV systems use analog cameras, which are connected to a Digital Video Recorder (DVR) through coaxial cables. The DVR compresses and stores the video footage on a Hard Disk Drive. Analog CCTV cameras are available in a variety of styles, including Dome Cameras, Bullet Cameras, and PTZ (pan-tilt-zoom) cameras. These systems are relatively simple to install, cost-effective, and offer good image quality.

IP CCTV Systems, on the other hand, use Network cameras that are connected to a Network Video Recorder (NVR) through an Ethernet cable or a wireless connection. IP Cameras can be used indoors or outdoors and are available in a variety of styles, including Dome Cameras, Bullet Cameras, Fisheye Cameras, ANPR (Automatic Number Plate reorganization) Cameras and PTZ Cameras. These systems offer higher resolution images than analog CCTV Cameras and can provide more advanced features such as facial recognition, motion detection, and remote access to video footage.

One of the key differences between the two systems is how the Video footage is transmitted and stored. Analog CCTV systems transmit the video footage over coaxial cables, while IP CCTV systems transmit the video footage over a network using internet protocols. This means that IP CCTV systems can be accessed remotely through a computer, tablet, or smartphone, whereas analog CCTV systems are generally limited to on-site viewing.
