AXIS 213 - Configuring the PTZ Network Camera 23
Overlay image limitations:
•If the image overlay and text overlay are larger than the video image, no overlay will be displayed. When also using a text overlay, this will occupy 16 pixels in height and as many in width as the video image. Please consider this when configuring the overlay 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 displayed.
•The maximum overlay image size supported by the AXIS 213 is the same as the maximum image resolution. See Tech- nical Specifications, on page 46.

Camera - 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 213 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. If set to Manual, select the desired Shutter speed from the
•Night vision - set the IR filter to on or off and click the Use IR Lamp button to light up the IR lamp on the front of the camera. The lamp will automatically switch off after 8 hours.
•Backlight compensation - this setting is used to make the subject appear clearer against e.g. a bright background.
Notes: •If configured by the administrator under Live View Config Layout IR Buttons the viewer is able to switch the IR lamp and IR filter on and off, directly from the Live View page.
•In certain situations, the white balancing system will not operate effectively. Problems may occur if the image contains no white color at all, or if the dominant color is not white. In these circumstances, the white balance may incorrectly be based on another visible color in the image, and colors may become distorted. A pale background picture with reddish or blue foreground objects is very symptomatic of this condition. In such cases it is recommended that a fixed white balance setting is selected.
