Love my doorbell t8200. What other products do you like or recommend for a town home?
Any of the Eufy indoor cameras would work great for any home, including townhouses. A great option would be the Eufy S350 Dual Lens Indoor Camera! 
There are tons of sales going right now in the Eufy app along with the Eufy website. You should definitely check them out to get a great deal on some awesome products! There are even some amazing bundles that include several different products at huge discounts! 
Hope this helps!
