The greater the resolution a piece of video has, the more precise the images that it produces are.
An image recorded with a security camera that’s based on analogue technology has 0.1 megapixels, generally speaking. In contrast, high resolution security cameras are able to capture images with thirty more times the detail (resolution) than their analogue counterparts. This means that not only are high resolution cctv cameras able to capture images that are clearer, but the images they capture show a greater area.
As a result, with a high resolution cctv system you require less security cameras for coverage of a given area. For instance: a high resolution security camera is able to provide surveillance for four pumps at a gas station, whereas a security camera based on analogue technology will only be able to properly record the goings on at one.
Simply put, given their higher level of efficiency and decentralized processing, high resolution cctv is in every way preferable to centralized systems with analogue cameras.

More Benefits of A High Resolution CCTV System
Analogue security systems usually only take care of capturing images; the processing and storage of these images has to be carried out subsequently with another centralized computer, and usually through the use of costly video management software.
This classic centralized structure doesn’t work with high resolution surveillance systems given that these systems are typically integrated with a network that has extensive bandwidth. Furthermore, a centralized computer can only process the information for so many cameras at one time.
On the other hand, when there’s a large network to tap into (with a vast quantity of computers) it’s far easier to handle the input from various cameras simultaneously. It’s also much easier to program automated notifications when motion is detected. In order to have this same high level of functionality with an analogue security system you’d to increase the number of centralized computers in the system, and this proves to be quite costly.
