Josef - the RUT956 datasheet says that it uses the Busybox shell. So if you are comfortable with unix shell scripts and cron then it should be straightforward to follow the advice earlier in this thread, ie: create a shell script that gets the temperature and posts it to the camera's On Screen Data (OSD) using a curl command. Then set up cron to run that script regularly - every minute, or whatever works for you.
