The 4G (LTE) security cameras are mobile monitoring cameras that use a 4G LTE/3G network to deliver live-view and send instant alerts. (Similarly, 2G/3G security cameras refer to the ones that work with a 2G/3G network).
As the above definition indicates, 4G cellular CCTV cameras require a separate mobile service plan to work. And the cellular data consumption of 4G IP cameras varies, depending on how often you watch live streaming and receive motion detection alarms, etc.
