Weather Data Overlay onto CCTV
Posted: Sun 04 Nov 2012 10:03 am
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.
