Seriously? Reality check time, folks.
$200 for a doorbell that then also requires a monthly fee to operate?
It's a motion-activated security camera that happens to have a button to ring a bell inside your house.
Okay. So instead of once in a blue moon maybe having a few hundred quid stolen from the home (mostly covered by theft insurance regardless), one instead pays an extra dozen quid a month (on top of $200+ up front) in hope of one day seeing fuzzy video of the ski mask a robber might wear when she perhaps (low probability) actually robs that particular home?
Duh.
