Analog VS IP Security Cameras

Analog Vs IP Camera (Ethernet or Megapixil) DVR vs NVR

What is the difference?

There are basically two types of video surveillance systems, CCTV (closed-circuit television), also known as analog, and IP cameras, also known as network cameras. Both CCTV systems and IP systems transmit video to the desired destination. CCTV systems convert the video signal to a format that can be used by televisions, VCR’s, or DVR’s. IP cameras convert the video signal into IP packets to be transmitted over the data network or internet to a network storage device such as a server, NAS, or by storing on board the camera. The IP system has the added benefit of using the network devices which can expand the range of the IP cameras beyond that of a CCTV system.

When comparing CCTV vs IP camera systems, both have advantages and disadvantages, but in the end it all comes down to price for quality.

Analog vs. IP for Beginners

Analog – Maximum 640×480 (307,200 pixels per image)
IP – starting at 1 Megapixel 1280×1024 (1,310,720 pixels per image) up to 10 Megapixel 3648×2736 (9,980,928 pixels per image)

Analog – General surveillance for overall environment (not detail specific)
IP – Clearly see facial recognition, license plates, forensic detail, loss prevention, general surveillance

Picture Quality after Enlargement
Analog – Pixelated
IP – Crystal Clear

Camera Density Per Server
Analog – Require more servers and uses more energy (Typically one server for every 16 cameras)
IP – Require fewer servers and uses less energy (Typically one server for every 64 cameras)
