AXIS P1214-E Network Camera Video noise is minimized. The file size is reduced, which can be useful if storage space or bandwidth is limited. However, prioritizing low noise may result in a very dark image, especially in low light situations. Overlay Overlays are used to provide extra information, for example for forensic video analysis or during product installation and configuration. Overlays are superimposed over the video stream. An overlay text can display the current date and time, or a text string. When using a text string, modifiers can be used to display information such as the current bit rate or the current frame rate. For information about available modifiers, see File Naming & Date/Time Formats in the online help . To enable overlays: 1. Go to Video > Video Stream and select the Image tab. 2. To include an overlay image, select Include overlay image at the coordinates. The overlay image must first be uploaded to the Axis product, see Overlay Image. 3.

The image, for example a company logo, is used to provide extra information or to mask a part of the image. For more information about privacy masks, see Privacy Mask on page 19. 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.
