The paper provides a detailed technical description of the complex detector “Obscura”. It consists of three registration points which were built around differential Cherenkov light detectors whose operation is based on a principle of “camera-obscura”. Here we consider experimental techniques used for Cherenkov light registration with this type of detectors. Description is given for hardware and software parts of a system intended for previewing and recording the signal from Cherenkov detectors. Protocols of detectors calibration and measurement control are discussed.
