Netatmo has introduced the first doorbell compatible with Apple HomeKit as one of the first big announcements in smart home devices at CES Unveiled. The Netatmo Smart Video Doorbell will let you ask Siri to use the doorbell’s app to check who’s standing outside.

The doorbell sends a video call to the app every time someone rings the doorbell to allow you to respond. You can also set Netatmo’s security app to send you alerts if people walk into specific areas you’ve marked so that you can detect if people are creeping suspiciously outside the house. The company suggests you can then “speak to the intruder and deter them from approaching” your home using the doorbell’s built-in mic and speaker. In the event someone tries to remove the doorbell from its wall mount or deactivate it, the security app will alert you immediately.
