The Unibrain cameras employ progressive scan CCD sensor which provides features according to each model. Basic 

functions and features are similar while each camera of its range would have their specific function support. The 

cameras- fully support the IIDC V1.31 specification such as registers, video format, mode of operation and control.   

Brightness of the camera can be controlled by changing the black level in the camera. The user can inquire the settings 

of the camera and control using the status control register. Adjust the brightness if the appropriate gradation cannot be 

obtained due to blurring of black portion of the image. The parameters of Brightness are changed inside the camera. For 

brightness, its parameters are shifted by the black level.
