On-Screen Graphics

On-Screen Graphics (OSG) is a new feature that allows placing custom image files on the top of the video as a layer. For example, it can be used as a watermark for security purposes, or a brand logo in the corner of the video image.

There is no interface within Web Configurator to configure On-Screen Graphics since it is a rarely used feature.

The URL commands can be used to complete the task instead.

The image that can be used as OSG has to be in YUV format (Image raster graphics) before uploading to the camera. There are several freeware converters available that convert images to

YUV format.

For example, one free trial version of YUV converter can be downloaded from Sunrayimage.com: http://www.sunrayimage.com/download/YUVTools_3.0_trial.zip

We do not guarantee the performance, terms of usage or availability of this product. The user has to read the terms of use first and proceed with installation if the terms are acceptable.

Please note that the image should not be larger than 640x480 pixels and should contain an even number of pixels. The image, once uploaded, cannot be resized. Therefore, please make sure that you have the image with the right size before uploading to the camera.

For example, we have the BMP logo with the size 204x106 that has been converted into YUV:

When the image is ready, upload it to the camera by the following URL command:

http://192.168.0.100/cgi-bin/cmd/encoder?OSG_IMAGE

Upon successful entry of user name ans password, the following upload window will appear.

file in your computer that you had prepared and press
