appropriate shutter speed and gain to obtain the correct exposure
.
Adjust the iris in seventeen
steps from F1
.
4 (largest size of lens aperture opening) ~ F22 (smallest size of lens aperture
opening).
■
Manual
Select this option to adjust the desired shutter speed, iris and gain
.
Adjust the shutter speeds in
eleven steps from 1/60 second (slowest) ~ 1/10000 second (fastest); the iris in seventeen
steps from F1.4 (largest size of lens aperture opening) ~ F22 (smallest size of lens aperture
opening) and the gain in fifteen steps from 0db (lowest noise level) ~ 28db (highest noise
level).
Day/Night:
■
Auto
The Network Camera automatically switches between day mode and night mode by judging
the level of ambient light. This mode is accessible only when the exposure mode is set to Auto.
■
Day mode
In day mode, the Network Camera switches on the infrared cut filter at all times to block the
infrared light from reaching the sensor so that the colors will not be distorted.
■
Night mode
In night mode, the Network Camera switches off the infrared cut filter to allow the infrared light
to pass through. This improves the sensitivity of the Network Camera in low-light conditions.
■
Schedule mode
The Network Camera switches between day mode and night mode based on specified
schedule. Enter the starting time and ending time for the day mode
.
Note that the time format is
[hh:mm] and is expressed in 24-hour clock time. By default, the starting time and ending time
of day mode are set to 07:00 and 18:00.

Video quality settings for stream 1 / stream 2: You can set up two seperate streams for the
Network Camera for different viewing devices
.
For example, set the Network Camera to a
smaller frame size and a lower bit rate for remote viewing on mobile phones
.
Or, set the
Network Camera to a larger video size and a higher bit rate for live viewing on web browsers.
■
Mode
The Network Camera offers two choices of video compression standards for real-time viewing:
MPEG-4 and MJPEG.
If
MPEG-4
is selected, it is streamed in RTSP protocol
.
There are four dependent parameters
provided in MPEG-4 mode for video performance adjustment.
■
Frame size
Select the video size. Note that a larger frame size takes up more bandwidth. The frame
sizes are
selectable in the following resolutions: 176 x 144, 320 x 240 and 640 x 480.
■
Maximum frame rate
This limits the maximal refresh frame rate per second
.
Set the frame rate higher for a
smoother video quality.
