Roku Smart Indoor Camera

With an 80db siren built in, this camera deters unwanted visitors, while motion detection zones reduce false alarms caused by innocent things like curtains fluttering in the wind. With the Roku Smart Home mobile app, you can see a full area in 1080p HD, even at night. The price drops from $26.88 to $19.88. Shipping is free over $35 or adds $6.99.
