Tapo V4: reconstructing C510W local control and media protocols

Tapo V4 reconstructs the Tapo C510W camera’s local control and media protocols from Android app analysis and device probing. A byte-level specification and Python client cover SPAKE2+ login, AES-128-CCM /ds requests, media-port authentication and SD-card clip download. The author reports operation on a C510W and limited reports from other models.
