How is possible to capture a screenshot on realtime video and send it via FTP or SSH every 10 min?

In a public environnement we are interested to capture a screenshot on the real time video 

and send this via FTP or SSH to a web site 

Someone can help me to understand if this is possible on meraki MV71 camera and related platform?

Regards

Although this is not a feature we have today, you can try the Pyhton script below courtesy of the Meraki Systems Engineering team. Note that this is provided as is with no support. It may not work, if it does work it may stop working at any time.

 

#!/usr/bin/python3

'''
=== PREREQUISITES ===
Run in Python 3 or 2

Install selenium, via macOS terminal:
Python 3 > pip3 install selenium
Python 2 > sudo pip install selenium

Install Chrome driver:
brew install chromedriver

Usage:
Python 3 > python3 screenshot.py
Python 2 > python screenshot.py

=== DESCRIPTION ===
UI script to take a screenshot every x seconds, given camera input link, until script manually terminated (control-C).

Re: How is possible to capture a screenshot on realtime video and send it via FTP or SSH every 10 mi

I don't believe MV cameras support that functionality. I know this isn't very helpful, but drop it in the 'make a wish' box in your dashboard.
