We are developing two new systems of a high-speed CCD camera, and an automated monitor telescope. This camera using a frame transfer-type CCD that enables us to take images each 27.3 msec at the highest speed. We wish to investigate accretion and eruption phenomena around compact stars by optical light. The system we have developed for automated monitoring of X-ray binaries and cataclysmic variables consists of a 30-cm reflector, a CCD camera, and a computer. It is a cheap system, but can monitor more than 150 systems each night. It will reveal long-term light curves of programmed stars of those transient systems, and catch sudden outbursts/decays. We will be able to start follow-up observations to clarify the mechanism of these activities as early as possible. We here report the current status of these projects, the target physics, and the future development.
