AVATTO SDL-V1-B60 Cilindro de fechadura inteligente, 60mm, impressão digital, Bluetooth, Zigbee, preto

The AVATTO SDL-V1-B60 redefines door security by replacing your traditional cylinder with a discreet smart upgrade—no external box, no bulky hardware, just a sleek black cylinder that fits European-standard doors and unlocks with a touch. Unlike add-on smart locks, this cylinder keeps your existing lock body and key, so you retain mechanical access while gaining fingerprint and app control. It’s a true DIY retrofit: swap the cylinder, pair the app, and go.

Highlights

• Fingerprint unlock: semiconductor sensor reads up to 200 fingerprints, fast and reliable
• Multiple access: fingerprint, Tuya Smart app (Bluetooth), or mechanical key
• Zigbee connectivity: optional remote access and automation via Tuya Zigbee Gateway
• Adjustable length: cylinder extends from 60mm to 100mm (30/30 to 50/50) to fit various door thicknesses
• Durable build: zinc alloy and stainless steel, C-level security cylinder
• Long battery life: 3x AAA batteries, up to 10,000 unlocks or 6–12 months, with low-battery alarm

In daily use

Installation takes minutes: remove your old euro-profile cylinder, insert the AVATTO SDL-V1-B60, and adjust the length to match your door (40–100mm thick). Register fingerprints via the Tuya Smart or Smart Life app—each user gets a unique print, and you can manage access remotely when connected to a Zigbee gateway. The cylinder responds instantly to a recognized finger, and if batteries run low, a warning alerts you well in advance. For emergencies, the mechanical key still works, so you’re never locked out.
