Good day,
As of today, the following appeared on the RING site:
This suggests that the variants of the Stick Up Cam products are largely the same thing, save for any included power adapters and their format. There appear to be two power adapter variants for sale:
These appear at first glance to differ only in terms of the connector with which they are equipped. The marketing for the solar panel power sources suggests that the “battery” variant is equipped with a barrel-type plug, whereas the others are perhaps equipped with a micro-USB input.
From the information available on the website, it’s not abundantly clear which products come equipped with which connector. 5V adapters with a micro USB format output are quite common, and can be found here. Similar products equipped with a barrel plug can be found here, though being less standardized than USB-output products, there are some additional refinements that need to be made to that list to find a product that may be suitable. Some guidance on finding replacement AC-DC wall adapters in the general case can be found in this post. And if you’re feeling adventurous, a product such as the RAC05-05SK/277/W may be suitable for providing a more compact implementation which would be more conveniently incorporated into small spaces. A suitable output connector would need to be provided in this case however along with a hardwired AC line connection, the latter of which is not recommended for those without appropriate training.
Insofar as Digi-Key does not officially provide support for products not on our line card, the foregoing information cannot be guaranteed in any way.
