For a preview of the image before saving, click Test. When satisfied with the settings, click Save. Please note
that the preview image will be in JPEG format, even though the settings are valid both for Motion JPEG and
MPEG-4.
Overlay Image
An overlay image is an image included in the video image. Follow these instructions to upload and use an
overlay image:
1. Go to Setup > Vide
o & Image > Overlay Image.
2. To upload the image to the AXIS 212 PTZ/AXIS 212 PTZ-V, 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.
Overlay image requirements:
The maximum overlay image size supported
by the AXIS 212 PTZ/AXIS 212 PTZ-V is the same as the
maximum image resolution. See Technical Specifications, on page
43.
When a text overlay is also used, this reduces the amount of
space available to the overlay image. To keep
the text readable at lower resolutions, the text overlay occupies proportionally more and more space, i.e., 16
pixels in height at 640x480, 32 pixels at 320x240 and 64 pixels at 160x120.
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. it is always the entire image that is displayed.

Advanced - Camera Settings
Lighting Conditions - To optimize the lighting settings according to your requirements, modify the following
settings:
Color level - Select color
or B/W
•Brightness - This can be adjusted in the rang
e 0-100
Sharpness -
Controls the amount of sharpening applied to the image
Exposure control - This setting is used to adapt
to the amount/type of light being used
Low Light Behavior - Exposure priority - This defines the balance between image quality and the frame rate.
Higher image quality may reduce frame rate and increase motion blur. A prioritized frame rate may instead
increase image noise. Depending on requirements, use this to give higher priority to the image quality or to the
frame rate.
Please see the online help for more information on these settings.
Advanced - MPEG-4 Settings
GOV Settings - The GOV settings control the composition of the MPEG-4 video stream. Setting the length to a
high value saves considerably on bandwidth. The Cyclic refresh parameter gives a smoother bit rate and can be
useful if bandwidth is limited.
