Amazon is selling the Yi Wireless Home Camera for just $19.99 when you enter promo code V3Z6L6M6 at checkout to save $9 off its regular price.

The wireless Yi Home Camera features 720p HD resolution with a 111-degree wide-angle lens. It can also zoom up to 4X and has a 940mm infrared sensor for clear vision in the dark. It has the capability to send instant alerts to your phone when activity is detected, and you can also initiate a 2-way conversation with its built-in microphone and speaker.

This product supports up to a 32GB micro SD card but doesn't include one. Luckily, you can grab one by Samsung on sale today for $8. Without it, you'd be able to view a live-stream of the camera's video via your smartphone but you wouldn't be able to save anything, so you'll want to make sure to pick one up. There's also a secure cloud service you can choose to pay for which could store your video footage.
