Auto slow shutter permits the capture of bright, clear images in low light
conditions by increasing exposure times. However, slow shutter limit times
beyond 1/60 s can cause motion blurring at low light levels.
To set the auto slow shutter limit:
1. Select 5 Camera Options
2. Select one of the following:
•
NTSC = 1/4 (default), 1/2, 1/60, 1/30, 1/15, 1/8
•
PAL = 1/3 (default), 1/1.5, 1/50, 1/25, 1/12
Wide dynamic range (WDR) technology provides clear, balanced images in a
variety of lighting conditions, such as entrances with varying levels of
indoor/outdoor illumination and situations where backlighting makes it difficult
to see a foreground subject clearly. Wide dynamic range improves detail in
underexposed (dark) and overexposed (light) areas but can lead to unnatural
looking video.
To enable/disable wide dynamic range:
•
Select 5 Camera Options
ON or OFF (default).
Advanced wide dynamic range operation is similar to wide dynamic range
operation but with 10 dB more range.
To enable/disable advanced wide dynamic range:
•
Select 5 Camera Options
OFF (default).
