Le procédé comprend les étapes suivantes : un NVR diffuse périodiquement un message de notification; le NVR acquiert un message de demande d'accès diffusé par une caméra de protocole Internet (IPC), le message de demande d'accès comprenant un identifiant de l'IPC, et le message de demande d'accès étant généré par l'IPC lorsqu'il est établi que le message de notification acquis diffusé par le NVR comprend un identifiant d'un AP sans fil prédéfini; le NVR détecte si l'identifiant de l'IPC dans le message de demande d'accès existe dans un ensemble d'identifiants prédéfini, l'ensemble d'identifiants prédéfini comprenant un identifiant d'une IPC géré par le NVR; et lorsque l'identifiant de l'IPC dans le message de demande d'accès existe dans l'ensemble d'identifiants prédéfini, le NVR autorise l'exécution d'une authentification d'accès sur l'IPC. La présente invention résout les problèmes existant dans l'état de la technique selon lesquels une pré-authentification automatique d'un dispositif ne peut pas être effectuée et le processus de pré-authentification est toujours difficile, ce qui simplifie le processus de pré-authentification de dispositif; et l'invention est utilisée pour une association de dispositifs.
