Kami - YI Technology's new home-security brand - has released its new Wire-Free Outdoor Camera. As it lacks the need for connectivity hubs and has batteries that can be recharged in a USB-powered holder, it can be installed anywhere the user wants. It has a 165-degree wide-angle camera that supports FHD video at 20 frames per second (fps).
