Abstract: Disclosed is a method for data transmission of audio and video in an end-to-end system. The end-to-end system includes a client terminal, a device terminal, and a service terminal. The service terminal includes a management server, a register server and a transmission server. The method includes steps of: S1: adding the transmission server to the management server; S2: adding the device terminal to the management server; S3: starting and initializing the device terminal; S4: starting the client terminal and connecting the client terminal to the device terminal; S5: performing an overload processing in the transmission server; S6: performing an overload recovering in transmission server.

Abstract: This present application discloses a handle and a lock structure applying to the handle, the handle including a handle portion and a rotating shaft portion for use with the handle portion, the handle portion and the rotating shaft portion are slidably and rotatably fitted to form a snap-fit mounting structure, and the handle portion is provided with a press-on member for locking the rotating shaft portion after the snap-fit is formed; the snap-fit mounting structure includes a first snap-fit portion and a second snap-fit portion, at least two snap-fit positions are formed on the first snap-fit portion, different snap-fit positions of the snap-fit mounting structure are selected to determine a mating use state of the handle portion and the rotating shaft portion, and the rotating shaft portion is rotated, so that the second snap-fit portion is snap-fitted to a corresponding snap-fit position of the first snap-fit portion.

Abstract: A smart lock comprises wireless enabled communication components and fingerprint enabled identification verification components. The fingerprint enabled identification verification components are configured to be at a location that a typical user's fingerprint is reachable and in a contact position when the user holds a handle of the lock. The smart lock is configured to be operable using Internet signals, bluetooth signals, and/or direct physical contact of a identification verification mechanism or method.
