Name
Function
To set the low-speed shutter (electronic sensitivity up) to [ON/OFF].
When the object becomes dark, this function automatically varies the
CCD accumulated time across several fields up to the set maximum
level to optimize the brightness of the object.
LS-SHUTTER
To set the DAY/NIGHT function (IR cut filter removable
function).When this function is set to [AUTO], the filter is
attached/removed automatically according to the brightness. When
the IR cut filter is removed, the color image is switched to B&W
image.
ICR
To set the maximum number of fields of the low-speed shutter [2fields,
3fields, 4fields, 5fields, 6fields, 8fields, 12fields, 20fields, 40fields,
80fields].
If the CCD accumulated time is set longer, the image frame rate will
decrease, and moving object could not be seen well.
NOTE: When [LS-SHUTTER] is [ON], [ICR] is [AUTO] and [PRIORITY] is
[S/N], [LS-MAX] can be set only to a range of [12 – 80 fields].
LS-MAX
To select the image attributes [MOTION, COLOR, S/N (fineness)] to
be prioritized when [LS-SHUTTER] is selected and the object
becomes dark.
PRIORITY
To set the maximum gain of the AGC [0dB, 4dB, 8dB, 12dB, 16dB,
20dB, 24dB].
The AGC is a function of amplifying the signal from the CCD to make
the object visible when the object becomes dark.
NOTE: When [ICR] is [AUTO], [AGC GAIN] can be set only to a range
of [12 – 24dB].
AGC GAIN
To select the high-speed shutter speed [OFF (1/60s), 1/100s, 1/250s,
1/500s, 1/1000s, 1/2000s, 1/4000s, 1/10000s, 1/20000s, 1/50000s].
When [LS-SHUTTER] is [ON], the shutter speed can be selected
from [OFF (1/60s) 1/100s].
If the shimmer of fluorescent lamp is annoying when the shutter
speed is set to [OFF (1/60s), set the shutter speed to [1/100s], and
the shimmer will be eased.
