Just created this script that talks to my ONVIF-based camera, since there’s no JPEG URL or anything similar to integrate it to Vera. I hope it helps someone, because it was really tricky to get this one working. Calling the ONVIF web sevice to get the actual image is not well documented.
Please notice that I’m using a free SMTP server that doesn’t require authentication.
*** This script wil NOT work with Gmail as the SMTP server ***
