Weather Data Overlay onto CCTV

For any of you that use Blue Iris CCTV software, there's an option to overlay data from an external file onto the display. This allows you to write a small script to show weather data from Cumulus on the CCTV image.

To get a decent amount of weather data on the overlay, you end up using an awful lot of image "real estate", so my VBScript pulls data from Cumulus's realtime.txt file and outputs a selection of weather parameters on a sequential basis with a 5-second delay.

An example of the results can be seen in the attached video. The weather data I have selected is displayed in the top-right corner. Any of the available parameters can be used and they can be different for each camera up to a maximum of ten cameras. The video shows an outdoor camera with corresponding outdoor data, but I have indoor temperature and indoor humidity overlaid on my indoor cameras.

If you really want to get some nice data on your IP Camera, use Webcam 7 to do it, it looks really nice on there.

Nice ideia... I also use Blue Iris for CCTV. Can you please publish your script, or give me some direction do build one myself.
I'm not a programmer, but if it's not too complicated I can try.

If your site is running on a linux system, you can also overlay next with image ImageMagick and pull the temp/windspeed out of realtime.txt

Thanks for the sugestion.
The system where I run Blue Iris is a Windows system.
