Something (UPS circuit breaker?) had caused the cloud camera's UPS to
quit outputting 120VAC power.  I power cycled the UPS via its push
button on/off switch which resides in the far back lower right side of
the UPS, and the cloud camera is now running fine.  I am running the
cloud camera for the remainder of the day for test purposes.  A new
UPS and/or battery plans to be installed when possible.
Please note that the Opticomm video to fiber converter module runs on
its own 120V wall wart that plugs into the same UPS as the cloud
camera's power supply.  This module has a nice "go/ no go" status LED,
which when is "red" indicates that it is getting power only.  When
"green", it is getting power and video, and when "off", it is getting
no power.  This status LED makes for a handy troubleshooting tool in
problem isolation.
