Hello,
I've run into a road block in my opencv motion detection script while trying to adapt an "import smtplib" into my loop. I did not create the original script so I can't take any credit for that. The problem I'm having is, when I run the script as is, and movement is detected it sends me an email for every frame that detected motion - it sends me a BUNCH of emails. How can I change the script so it only sends me (1) email every 60 seconds once movement was detected (and doesn't have a bunch of emails waiting to send in the background) and the loop function continues without interruption?
