At CES 2024 this week, Philips teased its first-ever smart deadbolt that works using a touch-free palm reading system that allows homeowners to unlock their front doors. The Philips 5000 Series Wi-Fi Palm Recognition Smart Deadbolt, will go on sale in the US early this year and will retail for 360. The deadbolt will join the Philips home security smart lock product lineup and will integrate with the Phillips Home Access app where users can remotely control the lock system through smart home assistants like Amazon Alexa or Google Assistant. It'll also have built-in Wi-Fi that makes it easier to pair and link to other smart devices. The system works by automatically detecting unique palm vein patterns through its built-in proximity sensors.

You can already unlock Schlage's Sense smart deadbolt with your voice through Siri, but you now have another choice if you're not a fan of Apple devices. The smart lock is now compatible with Amazon Alexa, so you can lock/unlock it or check out its status by barking out voice commands through an Echo speaker or any of the e-retail giant's Alexa-enabled devices. If you want to play with the integration a bit more, you can fire up the Alexa app and create "routines" for your smart devices triggered by key words. For instance, you can create a sequence that automatically locks your front door and switches off the lights when you say "good night." Schlage has another smart lock with Alexa integration through either Wink or Samsung SmartThings, but Sense could be the better choice if you don't have plans of automating all the appliances in your home.
