In this paper, we present the results of characterizing the properties of the Moravian Instruments G4-16000 CCD cameras, based on the Kodak KAF-16803 chip. Such cameras are widely used in several robotic telescope projects, as well as by amateurs. We demonstrate both large light response nonlinearity (up to tens of percents) and significant bias level instability of these cameras, and outline possible ways of overcoming these problems.
