[Auto] Automatically uses haze compensation. (11)[Day/Night] Set Day/Night mode to [Auto], [Day Mode] or [Night Mode] when the camera starts. You can also switch between [Day Mode] and [Night Mode] using the Day/Night mode function of the Admin Viewer (p. 144). Important • The initial camera settings (1) to (11) define the defaults that apply when the camera is started. Setting changes will be reflected only after the camera is reconnected or rebooted. Specify the settings used in the actual operating environment from the Admin Viewer (p. 141). • If the subject is a traffic signal or electronic scoreboard, etc., the captured video may flicker. In this case, try changing the [AE Mode] setting to [Auto (Shutter-priority AE)] and selecting a shutter speed lower than 1/100 to see if the problem improves. • Even if [AE Mode] is set to [Auto (Flickerless)] or [Auto (Flickerless 2)], some screen flicker may still occur under unstable light source conditions. • Setting a slow shutter speed may make it impossible for intelligent functions to work correctly. Select a shutter speed that suits the capture conditions and purpose. • In conditions where an outdoor scene is captured from an indoor location through a glass window, the camera may focus on the glass surface if there is dust or water there. Install the camera at the shortest possible distance from the glass surface. • [Smart Shade Control] cannot be used if [Haze Compensation] is set to [Auto] or [Manual]. • [Haze Compensation] cannot be used if [Smart Shade Control] is set to [Auto] or [Manual]. • If [Auto] is selected for [Day/Night], conduct a thorough operation test to check the effectiveness of the setting beforehand. • If [Auto] is selected for [Day/Night], set [Exposure] of the Admin Viewer to [Auto], [Auto (Flickerless)], [Auto (Flickerless 2)] or [Auto (Shutter-priority AE)] (p. 143). However, when [Auto (Shutter-priority AE)] is being used, night mode may not be activated even if [Day/Night] is set to [Auto], depending on the shutter speed. • Though the camera has an infrared filter, there is no effect on lighting due to infrared light as the camera does not have an insertion/removal mechanism for the filter. • The Day/Night Mode can be switched manually via the Day/ Night function of the Admin Viewer (p. 144), or via the [External Device Input] (p. 61) or [Timer] (p. 62) settings in [Setting Page] > [Event]. Note • Focusing may be difficult for the following types of subjects when [Focus] is set to [Auto] or [One-shot AF]. Subjects Difficult to Focus On A white wall or other A slanting subject lacking subject bright/dark contrast A subject reflecting strong light A subject consisting of only slanted lines or horizontal stripes A subject having no form, such as flame or smoke A subject seen through glass A fast moving subject A dark area or night view Subjects both near and far • After rebooting the camera, it is recommended that you check whether the camera is focusing correctly. • The focus ranges (approximate) are shown in the table below. Focus Mode Auto Fixed at infinity Day Mode/Night Mode Max. Wide-angle Max. Telephoto 0.3 m (12 in.) - infinity 0.3 m (12 in.) - infinity Focused at infinity Camera Control (1) [Digital Zoom] Set digital zoom to [Disable] or [Enable]. The higher the digital zoom ratio, the lower the video quality becomes. (2) [AGC Limit] Select one of 5 levels from 1 to 5 to automatically set the upper gain limit. The greater the value, the higher the sensitivity becomes. If you do not want to use the automatic gain adjustment, select [OFF]. Setting [AGC Limit] allows you to reduce noise when capturing video in low illumination. (3) [Smart Shade Control Strength (Auto)] Select [Mild], [Medium], or [Strong] for the control strength when [Smart Shade Control] (p. 47) is set to [Auto]. 48
