What is meant by 4K?

A 4K PoE (Power over Ethernet) security system is a type of surveillance system that combines high-resolution 4K cameras with PoE technology.

Higher Resolution

4K security systems typically have a resolution of 3840 x 2160 pixels, which is four times higher than standard high-definition (HD) systems. This means they can capture more detail, such as faces and license plates, aiding in better identification and recording of events.

Sharper Images

Thanks to the higher resolution, 4K systems provide crisper, more detailed images that remain clear even when zoomed in. This is particularly useful for monitoring wide areas or scenes that require detail recognition.
