Outdoor Camera no longer sends motion detection alerts when battery is plugged in to 2.0 Amp 5V power cube with outdoor cable

For the last year+ I have had my SimpliSafe outdoor camera on a covered front porch with a permanent 5V, 2.0 Amp (max) rated cube and outdoor 15 foot cable.  As of a few weeks ago, we started to notice that we were no longer getting motion detects on the camera.  After three reset/reboot conversations with Simplisafe they shipped me a new camera.  After replacing this camera, I get the same end result.

And before anyone suggests that I check the settings for the camera motion detection (detection ON and notifications ON) and the iPhone settings (all notifications in Simplisafe App turned ON), I already tried all of that with every different permutation of sensitivity setting.  Rest assured, everything is ON.  Plus I'm getting motion detect notifications under certain situations, as described below.

The camera is no more than 20 feet from the base station and router.  The router is no more than 20 feet from the camera and base station.  I have no problems streaming video.  That works perfectly, every time.

Note that the camera is actually detecting motion per the status light (blink once bluish on detect) with and without the power cube plugged in, but there were no motion detects on the timeline or sent to the iPhone when the power cube is plugged in.  After some experimentation, I found that when I left the battery cable and power cube unplugged, I was again consistently getting motion detect notifications, both on the timeline and via iPhone.  So I replaced the power cube and cabling and still the same result: motion detection per the status light but no events sent to the base station to update the timeline and notify via iPhone.  Again, after unplugging the power cube I started getting motion detect notifications again.

So why would this setup of outdoor rated permanently plugged in battery charging cube suddenly become a problem when it worked perfectly for over a year?  So far this points to two possible things, as I have changed out the camera:

1) A buggy software push to the cameras/base station from Simplisafe.
2) A bad base station.  Yet all other sensors seem to respond just fine.  Perhaps cameras have a separate antenna/circuit?

Anyone else experience this?  I'm sure SimpliSafe will "simply" say: "Buy our cable."  Well why?  Will you guarantee it?  5V, 2.0A outdoor setups are readily available and nothing special.  At the high cost of the camera, it should come standard.
