Vlogging and live streaming have emerged as dominant entertainment and social networking mediums. However, conventional cameras are often quite large and cumbersome to use, and not ideal for capturing photos and videos on a whim. What users need are high-quality and easy-to-use cameras that shoot quality spontaneous video footage. Thanks to the latest advances in image processing, artificial intelligence (AI), and Internet of Things (IoT), more affordable "casual" cameras, including action cameras, portable pan-tilt-zoom (PTZ) cameras, and unmanned aerial vehicle (UAV) cameras, have come to incorporate the advanced features that used to only be found on dedicated pro-level cameras. Consumers are increasingly picky about the functions and standards of these new devices.
