Overlay Image An overlay image is a static image superimposed over the video stream. The image, for example a company logo, is used to provide extra information or to mask a part of the image. Since it is static, the position and size of an overlay image will remain the same regardless of resolution and Pan/Tilt/Zoom movements. To set up a dynamic mask, which will always mask the specified part of monitored area, see Privacy Mask on page 22. To use an overlay image, the image must first be uploaded to the Axis product. The uploaded image should be a Windows 24-bit BMP image with maximum 250 colors. The image width and height, in pixels, must be exactly divisible by 4 and cannot be larger than the maximum image resolution. If combining text and image overlays, take into consideration that the text overlay occupies 16 or 32 pixels in height (depending on the resolution) and has the same width as the video image. To automatically scale the image to the resolution used by the Axis product, select the option Scale with resolution from the Transparency Settings page which is displayed when uploading in the image. To upload an overlay image: 1. Go to Video > Overlay Image. 2. Click Browse and browse to the file. 3. Click Upload. 4. The Transparency Settings page is now displayed: - To make a color in the overlay image transparent, select Use transparency and enter the RGB hexadecimal value for the color. Example: To make white transparent, enter #FFFFFF. - To scale the image automatically, select Scale with resolution. The image will be scaled down to fit the resolution used by the Axis product. 5. Click Save. To select the image to use as overlay: 1. Go to Video > Overlay Image. 2. Select the image to use from the Use overlay image list and click Save. To display the overlay image: 1. Go to Video > Video Stream and select the Image tab. 2. Under Overlay Settings, select Include overlay image at the coordinates. 3. To control the image's position, enter the X and Y coordinates. The X=0 and Y=0 position is the top left corner. If a part of the image is positioned outside the video image, the overlay image will be moved so that the whole image is visible. 4. Click Save. Using Overlay Text in an Action Rule Action rules, see page 33, can display an overlay text when the rule is triggered.
