A surveillance television camera including a camera base which is mounted on an installation surface and to which a surveillance television camera is mounted, a dome cover which is detachably attachable to the camera base and a locking device including a movable locking member mounted on the camera base and an elastic member biasing the movable locking member toward a joint surface of the movable locking member relative to the dome cover. The camera base has a joint surface relative to the dome cover. The dome cover has a fitting recess formed in the joint surface. When the joint surfaces of the camera base and the dome cover are joined together so that the dome cover is turned circumferentially thereby to be attached to the camera base, the movable locking member is fitted into the fitting recess of the dome cover by a biasing force of the elastic member.

Surveillance television camera

A video magnifier includes a monitor having a rectangular display screen, a base having a top on which the monitor is mounted, the base further having a right side, a left side, a front and a rear, a plurality of mounting sections formed on the right and left sides and at least one of the front and the rear of the base respectively, a camera holder detachably attached to one of the mounting sections, an imaging camera held on the holder so as to be detachable from the holder and having supporting legs supporting the camera within the camera holder at a predetermined height from a face to be imaged, and an image display control circuit for controlling the monitor so that an image imaged by the imaging camera is displayed on the display screen of the monitor.

Video magnifier

To set a distance between a lens mounting surface of a lens mount and a image pickup element for a back-focus of a interchangeable lens, the video camera comprises two guide pins fixed inside a front panel of a camera body parallel to an optical axis of a lens, said front panel which the lens mount is fixed in, a carrier supported by the two guide pins to move parallel to the optical axis, said carrier to which the image pickup element is fixed, a spring provided between the carrier and the front panel of the camera body to bias the carrier in such a direction that the carrier separates from the lens mount, a screw shaft rotatably assembled on the camera body by a holder to move parallel to the optical axis of the lens, said screw shaft having one end connected with the carrier and the other end on which an adjusting ring is screwed, and an opening formed in the camera body. When the ring is rotated by a finger or a tool being inserted in the camera body through the opening, the screw shaft moves back and forth, so that the carrier moves parallel to the optical axis of the lens along the guide pins. As a result, a change occurs in The distance between a lens mounting surface of the lens mount and the image pickup element.
