Watch over your home from anywhere in the world with these smart video doorbells

Get an extra 15 percent off RemoBell products this December.

Many of us will be spending the holiday period away from home. While your home is vacant, anyone could come knocking and you would never know. Not unless you install a RemoBell smart video doorbell, that is. These devices allow you to see exactly who visits your property from your smartphone, and you can even talk to visitors. The RemoBell S is now just $77.35 at the PopSci Shop when you use the 15 percent discount code MerrySave15.

Equipped with a 180-degree wide-angle lens, the RemoBell S captures everyone who steps foot in your front yard. The doorbell uses motion detection and night vision to keep watch over your home, and you receive an instant alert on your phone for every visitor.

To get started, you simply install the doorbell and sync it to your phone via the remo+ app (iOS and Android). The app gives you access to three days of recorded video, and you can see live pictures at any time. In addition, you can talk to visitors with full-duplex audio.

The RemoBell S retails for $99, but you can get it now for $77.35 with the code. You can also get the RemoBell W, complete with a powerful chime for $135.99 (worth $199) or the Alexa-enabled RemoBell Black for $76.49 (worth $149) with the code.
