The benefits of 4K Resolution CCTV
4K CCTV cameras are currently towards the top of the CCTV range in resolution. Like HD cameras, they offer excellent picture quality, but you can see even more detail at double the resolution. 4K cameras can, in some instances, remove the need for cameras to have an optical zoom, so although they are the more expensive option, it may be worth comparing them with HD cameras. If you are looking for highly crisp picture quality or extending the viewing distance of your existing CCTV system, this is a great option.
