DEVICE ACCESS METHOD, APPARATUS AND SYSTEM

Disclosed are a device access method, apparatus and system, wherein same belong to the technical field of security monitoring. The method comprises: an NVR periodically broadcasting a notification message; the NVR acquiring an access request message broadcast by an Internet protocol camera (IPC), wherein the access request message comprises an identifier of the IPC, and the access request message is generated by the IPC when determining that the acquired notification message broadcast by the NVR comprises an identifier of a pre-set WIFI AP; the NVR detecting whether the identifier of the IPC in the access request message exists in a pre-set identifier set, wherein the pre-set identifier set comprises an identifier of an IPC managed by the NVR; and when the identifier of the IPC in the access request message exists in the pre-set identifier set, the NVR allowing an access authentication operation to be performed on the IPC. The present application solves the problems in the related art that automatic pre-authe
