We discuss the strategy of search for fast optical transients accompanying gamma-ray bursts by means of continuous monitoring of wide sky fields with high temporal resolution. We describe the design, performance and results of our cameras, FAVOR and TORTORA. Also we discuss the perspectives of this strategy and possible design of next-generation equipment for wide-field monitoring which will be able to detect optical transients and to study their color and polarization properties with high time resolution.

Naked-Eye Burst is the only event to date observed in optical and gamma-ray ranges simultaneously with sufficiently high temporal resolution. This opens unprecedented possibilities for testing various models of both emission generation and the central engine behaviour during the burst. The temporal properties of the observed light curve, along with tight optical to gamma relation, suggest the intrinsic periodicity of internal engine, which is supposedly a newborn stellar-mass black hole surrounded by an unstable precessing massive accretion disk.
