Abstract

Monitoring apparatus and method for a CCTV monitoring camera, whereby an operation of a zoom lens and upward, downward, left and right rotating operations of the monitoring camera can readily be monitored while the monitoring camera performs a monitoring function. The monitoring apparatus comprises a rotation state detecting circuit for detecting states in which the monitoring camera is adjusted upwardly, downwardly, left and right, in response to an upward, downward, left and right rotation controller, a zooming state detecting circuit for detecting zooming states of the monitoring camera in response to a zoom lens controller, and an on-screen display control circuit for generating an on-screen display signal to display the upward, downward, left and right adjusted states and the zooming states of the monitoring camera on the screen of a monitor in response to upward, downward, left and right adjusted state detect signals from the rotation state detecting circuit and zooming state detect signals from the zooming state detecting circuit, and then combining the on-screen display signal with a video signal from the monitoring camera to output them to the monitor.
