High-performance switcher for multi-camera live streaming. It's a small, lightweight, and maneuverable model. My family bought it on a whim and used it once for event streaming, then left it unused. They said I could sell it, so I checked the operation, updated the firmware, and reset it. I think it's a great deal, as the power-on time is only a few hours. I only have a computer as an input source, so I only checked all the ports. From what I could tell, the switches don't seem worn out, and there's no sign of hydrolysis. The charging adapter has a notch and is a bit unusual. Other than that, HDMI cables, Type-C cables, and LAN cables are not originally included, so please prepare them yourself. It seems to come with the right to use Blackmagic Design's DAVINCI RESOLVE. I don't smoke, it was used in a non-smoking environment, and there are no pets. - Model Name: ATEM Mini Pro ISO - Brand: Blackmagic Design - Product Information: Live streaming switcher - Main Features: ISO recording, streaming function - Connection Terminals: HDMI input, USB-C output - Remarks: Version 9.5.1
