1. A camera, comprising a camera body, wherein a storage, an illumination product connection, and a setting terminal connection are provided inside the camera body,
the camera intermittently or continuously shoots and monitors a target scene to obtain a current image, and
obtains an exposure parameter of the current image;
the storage stores a light meter and a target illumination level set through a self-defined calculation;
the setting terminal connection receives control information and connects and transmits data to a setting terminal in a wired or wireless manner, the data comprising a position parameter of the target scene and a target illumination level setting parameter;
the camera obtains the target illumination level according to the target illumination level setting parameter received by the setting terminal connection through the self-defined calculation;
the camera acquires a region range of the target scene, calculates an image perceiving illumination level within the region range of the target scene for the current image collected, and calculates a current illumination level of the target scene for the current image collected through the light meter stored in the storage by combining or not combining the exposure parameter;
wherein the camera is further configured to:
1) Calculate the region range of the target scene according to the position parameter of the target scene received by the setting terminal connection and the current image collected;
2) Store the target illumination level obtained in the storage; and
3) According to the current illumination level of the target scene obtained and the target illumination level stored in the storage, calculate a deviation between the current illumination level and the target illumination level; increase a control parameter of an illumination level when the current illumination level is lower than the target illumination level; and decrease the control parameter of the illumination level and transmit the control parameter to an illumination product through the illumination product connection when the current illumination level is higher than the target illumination level; and
the illumination product connection is used to receive the control information, and connect and transmit the data to the illumination product in the wired or wireless manner.
