# Purpose: To download all Blink videos locally to the PC. Existing videos will be skipped.
# Output: All Blink videos downloaded in the following directory format.
#         Default Location Desktop - "C:\temp\Blink"
#         Sub-Folders - Blink --> Home Network Name --> Camera Name #1
#                                                   --> Camera Name #2

# Fixed By: ttteee90 on 03/19/2021
# Updates: Added infinite loop to re-run every 30 minutes as a keep alive to bypass pin prompt from Blink/Amazon
#          03/22/2021 - Cleaned up the code and added more debug messages. Added try/catch on invalid pin.
