Not very helpful, Justin. To state the obvious, the camera may not work correctly with a third-party adapter, but it does not work at all if there is no power supply, and I cannot use the one you provided for the reason given. If Ring is unable to provide a solution, it should at least be willing to provide information so that a customer can solve the problem him/herself. A 5vDC supply is readily available and in any case I can use the one supplied. For the camera end - and in the absence of helpful input - I will just have to measure up the barrel plug, buy a few of apparently compatible sizes and test them out.

Hi @Laminator. Best of luck. It is important to note that using third-party devices with your Ring products can void your warranty. Since none of these third-party devices have been tested with Ring products, you are using them at your own risk. I would suggest simply drilling a slightly larger hole to feed the barrel plug through or hiring a qualified electrician to safely complete this install for you.
