We will break down and enumerate what is definitely good for in terms of CCTV package to install:

  1. CCTV Camera Resolution

The camera resolution is very important. This is similar to megapixels measurement used for phones and computers. However, in CCTV camera the usual term is TVL or TV lines. This operates like the analog television system or camera. Hence, instead of pixels, in CCTV you simply mean TV lines. The higher these lines the better the quality of the images received. Most often, for home and business security purposes, the usual camera resolution may range from 420 to 700 TV lines. 700 TV lines is the maximum you may find. But in digital CCTV field, you may find other options with higher resolution cameras.   

2. Internet Viewing Resolution

Another important term is the Internet Viewing Resolution. It is measured as CIF (Common Intermediate Format). This defines the video sequence with a resolution like 352 x 288 that are converted for viewing in PAL OR NTSC formats. This may sound pretty complex. The camera captures an image at a certain number of frames per second. The CIF (Common Intermediate Format) resolution is how the DVR records the image or sequence of images. Storage of video files used to be large and very expensive. Lately, however, video storage is now more cost efficient. Then people usually give up quality, 4 CIF and maximum frame rate, for a reduced cost of storage. The 4CIF provides about 4 times the usual size of image for more clarity of images and facial recognition. This excellent in places like doorways, bank operations, front desks and many other sensitive places.
