The paper describes the methods and calculations for processing images obtained from IP cameras based on CMOS matrices, used at the SAO RAS Upper Observation Area. We present two methods for automatic switching of camera operation modes (day/night) and select the most preferred one. We also present methods for processing images obtained in low-light conditions. A camera was built to obtain series of images of the Polar star, and a method for calculating seeing from these series was described. The potential of using these image processing methods for the needs of SAO RAS is assessed.
