One of the most popular digital video security system features is the zoom CCTV or Closed Circuit TeleVision. There are many different types of Zoom CCTV cameras designed for a multitude of uses; be sure when shopping for one that you get the features you need.
What is a “zoom CCTV” anyway? It’s a digital video security camera used in CCTV that can vary its lenses focal length enough to enlarge objects farther away from the camera and make them appear closer (enlarged) and with more detail. These lenses are often referred to as varifocal.
Most box cameras that do not have built in lenses so they have the advantage of using Zoom CCTV lenses only. These can be manual lenses where they are basically positioned through trial and error by hand or they can be remotely controlled as well.
There are also some cameras that do have on-board lenses that zoom only and these are often found among the bullet type and dome type cameras. When we say “Zoom” only, we are referring to just the zoom function, as compared to a Pan-Tilt-Zoom or PTZ camera which has additional features including the ability to move horizontally or vertically.

We’ll save listing the PTZ cameras when we write about them but of course, if it says it’s a PTZ camera, than it must have a zoom lens.
