While wandering around the show floor at CES 2019 I noticed something new in smart home security -- cameras that replace your door's peephole, or hang over the top of your door (if you don't have a peephole).

Ring's Door View Cam and the Brinno Duo Smart Peephole DoorCam replace your door's peephole; the Remo+ DoorCam 2 hangs over the top of your door.

The idea, of course, is that you don't have to deal with electrical wiring or damaging your doorframe with a power tool.

Anyone can buy these devices, but it makes the most sense for folks living in apartments and any other rental properties with cranky landlords who have rules about installing devices.

It will hit stores "later this year," according to Ring, and they're designed to work with other Ring products.

On the inside of the door you can still look through the peephole, but you can also get alerts on your phone whenever someone ring's the bell or if activity is detected within range of the camera's motion sensor.
