This is an adapter that converts camera footage to iPhone or iPad. I am selling it because I don't use it often. The battery is sold separately. Below is the official product description: 【Professional Monitoring】Accsoon SeeMo turns your iPhone or iPad into a professional monitor, and by connecting to the Accsoon SEE app, it provides clear video image output transmission with no video image delay, making it convenient for cooperation with cameras and monitoring. 【Small but Powerful】The pocket-sized monitor is compatible with handheld cameras, gimbals, or creator studios. The small but convenient SeeMo functions not only as a video capture adapter but also as a phone clamp, making it easy to monitor, stream, record, and share through the Accsoon SEE app. 【SRT/RTMP for Live Streaming】Easy to set up and live stream via 4G/5G or Wi-Fi. With the Accsoon SEE app, you can use SRT/RTMP to stream to popular video distribution sites such as Facebook, Twitch, and YouTube, allowing you to reach your audience from anywhere. Other new features include a vertical video mode for creators, LUT writing for quick editing, and a calibration LUT addition function for those who want to use an iPad or iPhone as a monitor. 【Wide Compatibility】Accsoon SeeMo is compatible with most iOS devices, HDMI to iOS video capture adapters, and supports iPhone 8 and later generations, iPad Pro, iPad Air (3rd/4th/5th generation), and iPad mini (5th/6th generation).
