Difference Between Analog and Digital CCTV Camera

The main difference between Analog and Digital CCTV camera is how the video footages are being encoded and transmitted. Analog records the video in a format that can be received by a television or other receivers such as a VCR or monitor.
Whereas digital cctv camera which is also called IP camera has an on board web server which helps it to transmit video signal via a wireless medium to any monitor or even smartphones. Image quality is also an important metric here.
The analog camera has 2 megapixels in resolution whereas IP cameras currently go up to 5 megapixels in resolution.

3.Digital CCTV recorders, or DCRs record up to 100 images per second, and can record simultaneously from each camera.
