Take a look at the video GuardHome created in 2011 of a Pan, Tilt, Zoom CCTV camera. At the time the video was posted, this was one of the highest quality cameras available on the market.
Now let’s look another GuardHome video, this one was created and uploaded much more recently.
The comparison between videos illustrates the remarkable transformation in CCTV quality over the last six years. The camera in question is a 2 megapixel PTZ with an optical zoom of x25.
With advances of this magnitude in CCTV quality, how much better can it get?
