SkyBell's latest buzzer costs $199.
It's available in the US and has a handful of new features.
This version bumps up the resolution from standard definition to 1080p.
Installation is straightforward -- if you're familiar with basic electrical work.
It also offers free clip storage.
That means any time someone rings the doorbell, or if motion is triggered, you'll have a video clip that you can review later -- and even download for long-term storage.
And, it integrates with Amazon's Alexa, IFTTT, and Nest Cam.
