IP cameras vs analog cameras

Author: Anonym  /  Categories: Blog  / 

When you are in the market for a new video surveillance system, the first thing you need to decide is, do you want to install traditional analog cameras, or the newer IP cameras. The following will analyze the pros and cons of the IP and analog cameras.

Analog cameras have been available and successfully installed for many years. Initially, analog cameras were recorded to video tapes, however with the invention of disk based DVR's, analog cameras were captured to hard drives.

Over the last few years, many leading camera manufacturer's including Sony, Panasonic, Mobotix, Axis and others started manufacturing IP cameras.

The cost for IP cameras are a bit higher than their traditional analog counterparts; however they have many added benefits.

IP Advantages
IP cameras use progressive scan as compared to analog cameras which use NTSC or PAL interlaced. Progressive scans dramatically increases the image clarity which make the IP cameras superior.

IP cameras can have a very high resolution 1 megapixel or greater, producing a very high quality image. A multi-megapixel image can be used to cover a larger area, as one can digitally zoom the image at a later time. A 2 Megapixel IP Camera has a resolution 6 times greater than a standard analog camera.

Sony, Axis and others recently developed IP Security cameras with HDTV specifications, 1280×720 pixels (720p) and 1920×1080 pixels (1080p) and 16:9 widescreen format, at 30 frames per second.

Many IP cameras include audio support. This can be a great advantage at little extra cost.

Some of the other advantages of IP cameras are:

  • ability to utilize existing IP network infrastructure
  • Wi-Fi cameras
  • remote camera access
  • recording cameras at multiple physical locations
  • SD card optionftp and email support
  • Some cameras even have SIP support, Mobotix and Grandstream.

With IP Video, PTZ signal, audio and POE power, can be transmitted using a single CAT 5 cable; wheras analog would each require its own respective cable.

Analog Advantages
Analog cameras are an excellent choice for covert installations, because of their availability in pinhole size. There are still no real mini IP cameras, due to the size of its embedded microprocessor and memory.

Analog cameras cost less than IP cameras, although IP cameras did come down in price significantly.

All analog cameras, no matter who the manufacturer, are compatible with almost any DVR as they produce the same analog signal. When connecting an IP camera to a NVR, its compatibility must be ascertained. Recent standards such as ONVIF will make the compalibility issue less of a problem going forward.

Analog camera systems do not require any computer networking skills, wheras IP camera systems require the expertise of a Computer Networking Specialist. Traditional security dealers may be reluctact to go with IP in spite of its benifits, due to their lack of expertise in computer networking.

Summary
Both Analog and IP have many pros and cons, however IP is the wave of the future.
