@Todd,
I just installed the same mount (today) from Joseph at MotifsEtc on Etsy.com, though with a 10 inch Kindle (2017 version). Got it for $100 on sale at Christmas 2018. I know it is big but both my wife and my eye site are not so good and we plan to add several cameras in the future, so I will have a full screen of tiles :)
Also I installed it a little different than what most do here, I extended power from a lower existing outlet up to the tablet mount to an USB outlet (I bought everything Joseph suggested) It all fit perfectly.
I will be asking several questions too going forward but I think I am in the right forum.
My first question:
What is everyone doing about Security on their Tablets? Since our tablets are connected to the Internet 24/7 through our home networks this is major concern to me, I plan on installing Anti-Virus/Firewall. I have AVG on all my other devices so probably will use it. After all is installed, I will turn back On protection to stop Apps from Unknown Sources being able to be installed. Any other suggestions?
Also, does anyone have any experience with NoRoot Firewall on Google Store?
Thanks,
David
