It’s said you can’t put a price on peace of mind. Well, we’re doing it anyway — and it’s pretty reasonable.An indoor security camera lets you keep tabs on the things at home that matter most, whether that’s your kids, your pets, or your prized vinyl collection.We recommend the TP-Link Tapo C120, a sub-$40 indoor/outdoor 2K camera that can reliably distinguish between a variety of motions and sounds. The Tapo C120 also offers more customization options than most indoor cameras — and unlike with many competing models, all of these features work whether you pay for a subscription or opt to use your own local storage on a microSD card at no extra charge.
