About video settings
•
Fixed to use a fixed gain.
Example
If storage space or bandwidth is limited, try using a lower gain. This will reduce image noise and produce smaller image files.
Day/Night
The IR cut filter prevents infrared (IR) light from reaching the image sensor. In poor lighting conditions, for example at night, or when
using an external IR lamp, set the IR cut filter to Off. This increases light sensitivity and allows the product to "see" infrared light. The
image is shown in black and white when the IR cut filter is off.
If using automatic Exposure control, set the IR cut filter to Auto to automatically switch between On and Off according to the
lighting conditions.
The Day/Night shift level bar helps determine when the camera will shift from day mode to night mode. Normally, the camera
automatically changes mode from day to night when very dark (level 100 in the slider). By setting Day/Night shift level to a
lower value, the camera will change to night mode earlier.
Built-in IR Illumination
WARNING
Risk of eye injury. Do not look directly into the IR LED at short distance. Since the light provided from the IR LED is outside of
the visible range, it is not possible to see if it is active. Use the camera to check if the IR illumination is active.
The IR illumination can be activated or de-activated from the product's Live View page.
Other settings can be defined from Setup > Video > Camera Settings.
De-select the Enable IR illumination option to disable IR illumination altogether. If you disable the Synchronize IR illumination with
day/night option, IR illumination will not be synchronized with day/night changes.
About overlays
Overlays are superimposed over the video stream. They are used to provide extra information during recordings, such as a timestamp,
or during product installation and configuration.
About overlay text
An overlay text can include the current date and time, or a text string. When using a text string, so-called modifiers can be used to
display, for example, the current bit rate or the current frame rate.
You can choose between the following text overlay sizes:
Size
Small
Medium
Large
It is also possible to display text when an action rule is triggered, see How to include overlay text in an action rule on page 24.
How to include overlay text
1. Go to Video > Video Stream and select the Image tab.
2. To include date and time, select Include date and Include time.
