Analog CCTV Vs IP CCTV | Difference between Analog CCTV and IP CCTV

This page compares Analog CCTV vs IP CCTV systems and mentions difference between Analog CCTV and IP CCTV.

Introduction: The CCTV systems are broadly classified into IP CCTV and Analog CCTV. Both the systems allow us to view on smartphone, record on a digital hard drive and help us produce up to 4K 1080p HD images.

The main functions of CCTV systems are as follows.
• Allow viewing of video streams on smartphone and/or monitor.
• Allow storage of videos on a digital hard disk drive for later use.
• Used to produce 4K 1080p High Definition Images.

What is Analog CCTV ?

The figure-1 depicts analog CCTV system block diagram. As shown the major module or device is DVR (Digital Video Recorder). All the other modules are interfaced with DVR as shown in the figure on the back panel.

Analog CCTV Block Diagram

A typical analog CCTV system supports up to 32 cameras. It has limited support for smart features unlike IP CCTV system.

What is IP CCTV ?

The figure-2 depicts IP CCTV system block diagram. As shown the major module or device is NVR (Network Video Recorder) and ethernet switch. All the other modules are interfaced with NVR as shown in the figure on the back panel.

IP CCTV Block Diagram

A typical IP CCTV system supports up to 256 cameras. It supports more smart features compare to analog CCTV system.
