In NIGHT mode, camera provides the real time B/W video and can accept the IR light. When the illumination is getting
brighter, camera returns to DAY mode and returns its optical filter and switches to colour mode.
If set to OFF, camera operates just like a normal camera and does not perform NIGHT mode..

SW 1. ALC / ESC (Default: ALC)
Used to select iris control mode. When set to ESC, camera operates in electronic shutter control (ESC) mode and can
be installed with the manual or fixed iris lens. ESC mode is the most economic solution but may have some following
disadvantages comparative to ALC mode at auto iris lens:
• More smear and less clear image when shooting the very bright object.
• Colour rolling or video level hunting may occur under the florescent light when the camera operates in ESC and INT
modes (NTSC version only).
When set to ALC, camera operates in auto iris lens control mode and should be installed with either type of the auto
iris lenses (Video-drive type or DC-drive). Auto iris lens is used for best quality video.
SW 2. BLC (Backlight compensation) ON/OFF (Default: OFF)
If the subject you wish to view is too dim because of a bright background, set the BLC switch to ON to compensate for
the bright background. With BLC on, the background brightness may saturate in some cases. This function may not
operate properly if the object is too small compared to the area of the background. This function can be used with the
linear shutter (EE or ESC) and be OFF with auto iris lens (Al lens or ALC mode).
