Switch from Night
mode into Day Mode
This value controls the level of light where camera switches into
Day mode. Increasing it will make camera switch to Day mode at
a darker illumination level.
Brightness Meter Bar
This bar shows the illumination level at which cameras go to
night or day mode (Blue / Red bars), and shows the current
detected illumination level (Green bars). Use this bar to fine tune
the day/Night switch timing.
Get Current
Exposure Level
Clicking this button will refresh the illumination level reading from
the camera sensor. The larger the number, the darker the
environment.
Click the [Apply] button to confirm the settings or click the [Reset] button to re-enter
the parameters.
How it works
An important feature in this screen is that user may now customize the illumination level to
perform day/night mode switches.
On the horizontal brightness meter shown here, there are three colored bars. The bar
represents light amplifying levels 0 to 100, where 0 is Brightest and 100 is darkest. 0 means no
digital amplification of incoming light signals, which means that the environment is bright
enough for the camera to get good quality images.
When the environment gets darker, as when the sun is setting over the horizon, the
environmental gets darker. To maintain proper image brightness level, the camera will attempt
to digitally amplify the light signals received by the sensor. The Blue one is the level at which
camera will go into night mode, and remove Mechanical IR cut filter and open IR LED if
available. The red one indicates the illumination level at which the camera will consider bright
enough to go back to day (Color) mode.
The Red bar should always be to the left of the blue bar. As camera go from day to night mode,
more lights are allowed inside (the IR filter is removed), so the detected light signal level will
increase. If the night-to-day illumination level is too close to the day-to-night level, the camera
will immediately consider it bright enough to go back to day mode, which will result in
continuous day/night switching.
