Hello! I do not know if Best Buy can help you install the Ring Video Doorbell, but any handyman can help you install it. The Ring Video Doorbell can either be battery-operated, which will need to be taken off the wall to recharge, or can be hard-wired connected, which will not require periodically being taken off the wall for recharging. I had replaced my original doorbell with the Ring Video Doorbell unit. My original doorbell was removed and was replaced/rewired with the new Ring Video Doorbell. Works like a charm! If you want to place it in a new location which has stucco, there should not be a problem with installation. It comes with a plate which is attached to the wall with a few screws. A few screw holes will have to be drilled into your stucco wall. After the plate is attached, the unit just slides & clicks on to the plate and is further secured with another screw (unit to wall plate). If it is not hard-wired for electricity, then the unit will have to be taken off the plate periodically for recharge. How would you know when to recharge? You will be able to see the level of charge on your app or website, when you sign into your account. Hope this helps! This Ring Video Doorbell is wonderful for better security. Highly recommend!
