In the last post on 7th April 2011 we had covered the different technologies available to you and a broad idea of the kind of output you can get from them. At Dee Cee Security Systems Pvt. Ltd. we are committed to suggest you the right technology and the right solution which exceeds your expectations and is within your budget.
Here we will give you a idea of the main aspect of CCTV Cameras which every buyer is looking for but gets confused when he sees technical words like CIF, 4CIF, D1,etc.
Before we go into understanding the above, you need to understand one word which "PIXEL". What is a Pixel?, while you hear megapixel, HDTV and other terminologies nowadays, very few people understand that they are based on amount of pixels they support.
In simple terms, PIXEL stands for Smallest Picture Element. See the below picture:

What you see above is a Monitor on the left. On the right side you see a image which is zoomed in version of the image. The selected area is shown as a square on the left side.The element has been red colored and named as Pixel. That is a Pixel. If we name that Pixel as P0 and the next one as P1,P2,P3...... and so..on... then we would get the image resolution. A image resolution bascially refelcts the total number of pixels the image.
Do understand the number of pixels is directly proportional to quality of picture. So higher the number of pixels better the picture clarity.
Following table gives you a idea of the number of pixels expected from a Analog Camera.
To understand the above, i will give you example, QCIF which gives you a resolution of 176 X 144 in PAL( used in Asian Countries) means it will give you a resolution of 176 Pixels X 144 Pixels horizontally and vertically. Thus as we go higher the image size increases.
The following is table of Digital Video Resolution ( or IP Camera Resolution):
So you can see the number can go a lot higher in Digital Video Resolution compared to Analog Video Resolution thus offering you Best picture Quality.
