Description

Apparatus and method for surveillance The present invention relates to a monitoring device and method, and more specifically, to a monitoring device and method that optimally corrects setting information of each camera through communication between a plurality of cameras that photograph a monitoring area. A camera can be used for the purpose of monitoring a surveillance area. The user can perform surveillance of the surveillance area by referring to the video captured by the camera. Multiple cameras may be installed in the surveillance area. The multiple cameras may be configured with different settings. Depending on the differences in settings, the object recognition results may vary by camera. Therefore, the emergence of an invention that optimizes the configuration information of each camera to improve the object recognition performance by cameras installed in a surveillance area is required.
