LTE is mobile network technology and stands for Long Term Evolution. Typically it's referred to as 4G LTE in short. LTE offers faster wireless data transmission than 3G, which means you can download music, video, websites, or live stream faster. Most cellular security cameras offer both 3G/4G LTE options for data transfers and live streaming. Before buying any cellular surveillance cameras, make sure it is compatible with your service provider's 4G LTE network.
