The differences between locks come down to connectivity. The $279 Smart Lock Pro is the full-featured, familiar-looking model with support for WiFi (through a bundled Connect bridge), Bluetooth, HomeKit and Z-Wave Plus. The regular Smart Lock, meanwhile, has a new, no-frills design that drops the starting price for a lock from $179 to $149. Both locks still carry signature tricks like auto-unlocking and virtual guest keys, and they're available right away.

August isn't leaning solely on locks, though. It's also trotting out the August Doorbell Cam Pro, which upgrades the company's existing doorbell camera with a built-in floodlight (to offer color footage at night) and a video buffer that captures the few seconds leading up to a motion trigger, so you'll see the full context of what's happening -- you'll see that delivery driver walking up to the door, not just when he's ready to leave. You should also see better video quality. The Doorbell Cam Pro doesn't ship until October 10th, but its $199 price is the same as the earlier standard model. As such, you might as well spring for the Pro if you're a first-timer or don't like the lock you have now.
