# QUII Helper: reconstructing Qualvision intercom communication

> QUII Helper reconstructs communication with QUII and Qualvision video intercoms in a Python client for snapshots, video, RTSP forwarding, device inspection, and door commands. Its protocol notes map LAN TCP setup, encrypted play, media handling, and cloud preview flow to behavior found in inspected app builds.
