Performing Operations and Settings in the Admin Viewer Important • If it is set in the Admin Viewer, the same focus mode will occur in the viewers of other users also. • Setting the shutter speed at [1/1 sec] in manual exposure (p. 143) will disable the [Auto] and [One-shot AF] focus modes in Control for Admin. Switch the focus to [Manual] and adjust it to your subject. • Please refer to the notes on p. 48 for subjects that are difficult to focus on, focus ranges and other information. • Changes to focus mode in the Admin Viewer will not be reflected in the settings on the setting page. • Note that if you set the focus manually it will remain fixed. „ Setting the Exposure (1) (2) (3) (4) (5) (6) (1) Exposure Mode Select from [Auto], [Manual], [Auto (Flickerless)], [Auto (Flickerless 2)] or [Auto (Shutter-priority AE)]. If [Auto] is selected for [Day/Night] under [Camera] in the Setting page (p. 48), select [Auto], [Auto (Flickerless)], [Auto (Flickerless 2)] or [Auto (Shutterpriority AE)]. [Auto] The exposure is controlled automatically. [Manual] The exposure is set by adjusting the shutter speed and gain values manually. [Auto (Flickerless)] In this mode, video flickering caused by fluorescent lights, etc., can be reduced. The shutter speed is automatically adjusted according to the brightness of the environment in which the camera is used. [Auto (Flickerless 2)] Use this mode if flickering is not reduced when [Auto (Flickerless)] is selected. However, the automatic adjustment range for the shutter speed is suppressed so as not to exceed 1/100 sec. in this mode, resulting in improper exposure (i.e., excessive brightness) in some cases. [Auto (Shutter-priority AE)] In this mode, the desired shutter speed can be specified. (2) [Exposure Compensation] When [Auto], [Auto (Flickerless)], [Auto (Flickerless 2)] or [Auto (Shutter-priority AE)] is selected for 5 [Exposure], the exposure compensation value desired can be selected from nine levels (-4 to +4) using the slider. To darken the video, select a negative value. To brighten the video, select a positive value. Admin Viewer/VB Viewer (3) [Metering Mode] When [Auto], [Auto (Flickerless)], [Auto (Flickerless 2)] or [Auto (Shutter-priority AE)] is selected for [Exposure], the metering mode can be selected from [Center-Weighted], [Average] or [Spot]. For an explanation on each item set in [Metering Mode], see [Metering Mode] in the Setting page (p. 46). (4) [Shutter Speed] When [Manual] or [Auto (Shutter-priority AE)] is selected for [Exposure], select the shutter speed desired. If [Manual] is selected, set the shutter speed in the range of [1/1 sec] to [1/16000 sec] from a pulldown menu. If [Auto (Shutter-priority AE)] is selected, set the shutter speed in the range of [1/2 sec] to [1/ 16000 sec] from a pull-down menu. When capturing a moving subject, selecting a higher shutter speed can reduce blurry video capture. (5) [Slow Shutter] You can set slow shutter if [Exposure] is set to [Auto], [Auto (Flickerless)] or [Auto (Flickerless 2)]. Select a value in the range of [1/2 sec] to [1/30 sec] from the pull-down menu. As slower shutter speeds generate afterimages when capturing a moving subject, select an appropriate time according to the capture conditions. (6) [Gain] If [Manual] is selected for [Exposure], set a desired gain value. Moving the slider to the left decreases the gain (sensitivity to brightness) and darkens the video. Moving the slider to the right increases the gain and brightens the video. Important • If the subject is a traffic signal or electronic scoreboard, etc., the captured video may flicker. In this case, try changing [Exposure] to [Auto (Shutter-priority AE)] and then select a shutter speed lower than 1/100, to see if the situation improves. 143
