Lenovo A5 Plus smart lock: palm vein and 3D face entry on a plain mechanical mortise, sourced to order for Dubai homes that lock the door by hand.
The Lenovo A5 Plus is a palm vein smart lock for Dubai buyers who want vein recognition without motorised locking. It pairs palm vein, 3D face and fingerprint entry with a simple mechanical mortise, the only body Lenovo offers for this model, and it suits smaller households that value easy entry over automation. As you approach, radar wakes the lock. You hold your palm over the reader or look at the camera, and the handle opens the door. Fingerprint, PIN, card, the Tuya app and a mechanical key are all there too. A bell press sends a video call to your phone, so you can talk to visitors and open remotely, and clips stay on Tuya's cloud for one rolling day. A 4200mAh rechargeable battery powers it, about three months per charge in Lenovo's lab. Because the mortise is mechanical, the deadbolt is thrown by hand rather than automatically. What else you need: Wi-Fi at the door and a mortise cut-out that suits the mechanical body. Lenovo gives no door thickness range, so we measure the door and confirm the fit with the supplier. Heat is not an issue, with a rating up to 70°C. The limits are real. Every method tops out at 50 users, the battery is the smallest in the range, the colour is black only, and no UAE shop carries it, so it is sourced to order with a lead time.

The A5 Plus suits Dubai homes where palm vein is the priority and automatic bolts are not. It is a sensible match for families with older parents, cooks or cleaners whose fingerprints read poorly, since the palm reader looks at veins under the skin. Because Lenovo publishes no door thickness for it, we measure the door, check the mortise cut-out and confirm with the supplier before ordering. Its weather rating is quoted as IP54 by Lenovo and IP52 by an overseas dealer, so plan on a covered entrance and wipe the panel rather than wash it. A DEWA cut leaves entry untouched and only pauses the app. Tenants need landlord consent, and fire-rated tower doors need building approval. Stock is the practical hurdle: no UAE shop carries it and the one overseas listing we know of is sold out, so allow time.
Lenovo in the UAE. Lenovo-branded smart locks and cameras are made by Yunka Intelligent (Shenzhen) under licence as part of Lenovo's smart-device ecosystem, rather than by Lenovo's computer business. Most of the locks run on the Tuya / Smart Life app, while the cameras use the cam720 app. UAE availability is patchy: a few models are stocked by specialist smart-lock retailers and many are sourced to order, so we confirm the exact model, lock body and lead time before quoting.
