37. and if the first person identity information meets a second preset identity condition, starting the first camera and the second camera simultaneously.

In the embodiment of the application, different preset identity conditions can be preset, specifically, if the first person identity information is successfully matched with the identity information sample in the preset identity information base, the first person identity information includes the identity information of the owner or the acquaintance, thus, it can be determined that the first person identity information satisfies the first predetermined identity condition, for example, the first person identity information includes at least one face identity information, if the at least one face identity information includes a face identity information that is successfully matched with the face information samples in the identity information base, for example, the first person identity information includes at least one piece of voiceprint information, and if the at least one piece of voiceprint information includes voiceprint information successfully matched with a voiceprint information sample in the identity information base, it is determined that the first person identity information satisfies the first preset identity condition. In this case, if the second person location area of the at least one visitor is located in the first photographing area, it may be determined that the target photographing area is the first photographing area, and thus, the first camera may be turned on, video monitoring may be performed by the first camera, and if the first camera is originally in an open state, the open state of the first camera may be maintained. If the second person position area of at least one visitor is in the second shooting area, the target shooting area can be determined to be the second shooting area, so that the second camera can be started, and video monitoring is carried out through the second camera.

If the matching of the first person identity information and the identity information sample in the preset identity information base fails, the first person identity information is the identity information of strangers, and therefore the first person identity information can be determined to meet the second preset identity condition.
