Introduced in VDG Sense version 2.7.2
The customMessage signal with the supplied value parameter is used to link a status message to a camera. This status message can be showed in a custom OSD which is described here.
Special care must be taken when including xml specific characters. These are ‘&’, ‘<' en '>‘. The ampersand (‘&’) character can not be sent by this command because it will be part of the URL. See next paragraph.
As the value of this event is in the query part of an URL, the ampersand character (‘&’) cannot be part of it. It must be URL Encoded. See i.e. http://www.w3schools.com/TAGS/ref_urlencode.asp. The best practive is to URL Encode the complete value.
