Closed Circuit Television or CCTV Surveillance systems are TV systems that are installed and monitored for security and surveillance purposes, in which signals are publicly distributed. Normally, you will see this in place in some establishments and offices. Despite this is an old technology that has been around for years, there have been significant advancements in CCTV displays over time.

Unlike old Closed Circuit TV systems that had low resolution and small black & white monitors without any interactive capabilities, the modern-day CCTVs are colored, have high-resolution displays, and loaded with outstanding features that help ensure top-notch security of the premises. Some CCTV systems feature the zoom in facility. This means you can zoom in on the image or video, track any mysterious activity on the screen and take action immediately, which otherwise may be difficult to observe on old and black & white display screens.
