摘要

The pivoting mirror (4) in front of the camera objective lens (3) allows the surveillance zone to be scanned, without the camera itself having to be moved. A second small mirror (8) is fixed in position in front of the objective (3), so that a peripheral date and time mechanism (10) is imaged onto the film or TV screen. Pref. the first mirror (4) is biased by a spring (7) and is moved against the bias by a cam (6), which is driven by a remotely controlled motor. The fixed mirror (8) may be located in front of the objective (3) for short focus shots and in front of the camera tube (2) for long focus shots.
