Delta Home has just rolled out its most advanced lock yet, the X90 Ultra AI, and it's a big step up from a regular lock. Priced at Rs. 34,990, this lock is built for homeowners who want strong security along with everyday convenience. Let's look at what makes it stand out.
A Door Lock With Camera for Real-Time Viewing
One of the most useful parts of the X90 Ultra AI is its door lock with camera setup. It comes with a large 4.5-inch HD digital door viewer, so you can see a clear, live view of whoever is standing outside your door. This works like having a small CCTV screen built right into your lock. No more squinting through a tiny peephole you get a full, bright picture of your doorstep any time you need it.
Seven Ways to Unlock, Not Just One
Most locks give you one or two ways to get in. The X90 Ultra AI gives you seven: 3D face recognition, palm vein scanning, fingerprint, PIN code, a temporary password, an RFID card, and a regular mechanical key, plus mobile app access. If one method doesn't work for any reason, you always have a backup. The face and palm recognition use deep-scan AI technology, so they're built to be more accurate than the basic face unlock found on many other locks.
A True Smart Home Door Lock
As a complete smart home door lock, the X90 Ultra AI connects with other devices around your house. The moment you unlock the door, it can trigger your lights, AC, or curtains to respond automatically. This turns a simple "I'm home" moment into a smooth, automated experience instead of you having to adjust each device by hand.
The lock also comes with its own voice assistant, called Lucy AI, and supports two-way voice intercom, so you can actually talk to whoever's at the door through the lock itself. It also works with Alexa and Google Assistant for voice-based control.
Built as a Reliable Main Door Smart Lock
Your main entrance needs a lock that won't let you down, and that's where the X90 Ultra AI shines as a dependable main door smart lock. It's made from architectural-grade aluminum and zinc alloy, with a stainless steel deadbolt, so it's built to handle daily wear and tough weather. It works on doors between 40mm and 120mm thick, and the whole unit has been tested for salt spray exposure and extreme temperatures, running anywhere from -25°C to 70°C.
It also holds up to 300 users, with space for 100 fingerprints, 100 passwords, 100 RFID cards, and 50 face or palm profiles handy for larger families or shared properties.
A Dependable Main Door Automatic Lock
Convenience is a huge part of the design. As a main door automatic lock, the X90 Ultra AI locks itself automatically once your door closes, so you never have to double-check if you remembered to lock up. The lock runs on a 4200mAh rechargeable lithium battery (with a backup 2500mAh), giving you roughly 7 to 8 months of use per charge. If the battery does run low, you'll get an alert well in advance, and you can even jump-start the lock using a power bank through its Micro USB port, or fall back on the mechanical key.
A Complete Automatic Door Lock System
What really brings everything together is how the X90 Ultra AI works as one full automatic door lock system instead of a bunch of separate gadgets. You get the camera viewer, AI-based face and palm recognition, remote app control, auto-locking, smart home connections, and strong physical security, all in a single device. It also works offline, so your door doesn't depend on a WiFi connection to stay secure, lowering the risk of remote hacking.
Why It's Worth Considering
Beyond the tech, DeltaHome backs the X90 Ultra AI with a 2-year onsite warranty, 7 years of product support, free installation across more than 15,000 pin codes in India, and a 30-day money-back guarantee. Early customer reviews highlight the smooth installation process and praise the lock for standing out from other smart locks in its price range, thanks to its mix of face recognition, palm vein scanning, smart home features, and sturdy build.
For anyone looking to upgrade their front door into something smarter, safer, and genuinely easier to live with, the DeltaHome X90 Ultra AI is a serious option worth checking out.
