Overlay Image Settings
An overlay image is an image included in the video image. This might, for example, be
your own company logo. Follow these instructions to upload and use an overlay image:
Overlay image requirements Overlay image limitations
Image Formats Image Size
The height and width of the overlay
image in pixels must be exactly
divisible by 4.
1. Go to Setup > Video & Image > Overlay Image.
2. To upload the file (a logo or image) to the AXIS 231D+/232D+, click the Browse
button and locate it on your computer or server.
3. Click the Upload button and follow the on-screen instructions.
4. The image is now available in the Use overlay image drop-down list.
5. Click Save.
6. Go to Setup > Video & Image and modify the parameters under Overlay Settings.
Advanced Camera Settings
To optimize the lighting settings according to your requirements, modify the following
settings under Lighting Conditions:
• White balance - the white balancing system in the AXIS 231D+/232D+ can
automatically detect white in the image and intelligently use this as a reference
for other colors.
• Exposure control - this setting is used to adapt to the amount/type of light being
used.
• IR cut filter (AXIS 232D+ only)- when the IR cut filter is set to OFF, the camera
will be able to ‘see’ infrared light, e.g. at night, thus making the image clearer.
The image is shown in black & white when the IR cut filter is off.
• Windows 24-bit BMP (full color)
• Windows 4-bit BMP (16 colors)
• If the image overlay and text overlay are larger
than the video image, no overlay will be dis-
played. When also using a text overlay, this
will occupy 16 pixels in height and as many in
width as the video image.
• If the overlay is initially positioned so that
part of it is outside the video image, it will be
relocated so that it appears over the video
image, i.e. the entire image is always dis-
played.
• The maximum overlay image size supported by
the AXIS 231D+/232D+ is the same as the
maximum image resolution. See Technical
Specifications, on page 46.
