Thanks for your advice. I have the Viofo dual cam. The garage is several stories down, so no WiFi. If I could get WiFi to work that deep underground, I would. It is the ideal situation to be alerted to an event (motion detection). If it's a really busy area, then not so good as you'll keep getting alerts.
On a different note, I have the Ring outdoor cam which I will use indoors at my place. WiFi. Have not set it up yet but will soon.
