Megapixel Cameras and Surveillance Software User Manual

Day/Night

“Day/Night” settings apply only to MP3DN camera.

 “Automatic” enables the camera to automatically switch from daylight conditions (using the color sensor) to nighttime conditions (using the monochrome sensor), and back based on the Threshold settings (see below).

 “Day” enables the daylight mode and disables the nighttime mode.

 “Night” enables the nighttime mode and disables the daylight mode.

 “Threshold” adjusts the automatic switching of the camera:

 “Switch At” adjusts the level of darkness to switch from daylight to nighttime mode.

 “Toggle Guard” adjusts the level of brightness to switch from nighttime to daylight mode. Toggle Guard set to 0% corresponds to “Switch At” set to 100%. Toggle guard should be adjusted to prevent mode toggling during the transitional lighting.

Auto-Iris

The Auto-Iris menu allows monitoring the state of the automatic DC iris. If the scene is too dark, the camera will open the iris fully. This allows more light onto the sensor and will substantially improve the low-light performance. If the scene is too dark when the camera is started, the camera will not close the iris until there is enough illumination.

Camera DC auto- iris can be configured using “Auto-Iris” menu:

The iris can be disabled by un-checking “Enabled”. The camera will open the iris fully and have electronic auto-exposure working. This configuration is identical to using a manual lens.
