The current smart camera features are mainly video surveillance, voice dialog, security alerts and video playback.
一、video monitoring
Video surveillance is the core and most basic function, the current smart camera is the mainstream resolution is 1080P HD, the network requirements are high. Most of the home camera is through WiFi to data transmission, which has the advantage of easy to move location.
