SECTION 1: INTRODUCTION Preset Freezing This feature freezes the scene on the monitor when moving to a preset. This allows for smooth transition from one preset scene to another and also guarantees that masked areas will not be revealed when moving to a preset. Presets Each of the user-definable presets can be programmed to use pan, tilt, camera settings and other settings.

SECTION 1: INTRODUCTION Slow Shutter Slow shutter function extends the exposure time to accumulate more light when the light condition is low, resulting in a brighter image. Backlight Compensation (BLC) Back Light Compensation ensures proper exposure of subjects in the foreground. Back light compensation adjusts the camera’s exposure in challenging lighting environments such as hallways and doorways, so the entire image of the subject in the foreground is properly exposed when there is a bright light source behind the subject.
