The TTLock DB2 Smart Video Doorbell is a next-generation wireless video intercom system that brings intelligent security to your doorstep. With 2MP Full HD resolution, smart human motion detection, crystal-clear two-way audio, and built-in Bluetooth gateway functionality, the DB2 keeps you connected to your home 24/7 - whether you're across the street or across the globe.
Designed for easy DIY installation and powered by dual high-capacity lithium batteries, this smart doorbell supports local TF card storage (up to 128GB) and optional cloud recording, ensuring your footage is always secure. Plus, its infrared night vision delivers sharp images even in complete darkness.
Works seamlessly with the TTLock App
Future-ready Bluetooth gateway for smart lock integration
No wiring required - perfect for apartments, houses, and rentals
Capture every detail with a 2-megapixel CMOS sensor and ultra-wide-angle lens. See visitors' faces, packages, and surroundings in crisp clarity - day or night.
Equipped with 6 infrared LEDs, the DB2 automatically switches to night mode when ambient light drops, delivering clear black-and-white video in total darkness.
Unlike basic motion sensors, the DB2 uses PIR (Passive Infrared) technology to detect body heat and movement - reducing false alerts from pets, leaves, or shadows. Get instant push notifications on your phone the moment someone approaches your door.
Speak directly to delivery drivers, guests, or family members through the TTLock mobile app. Built-in noise reduction ensures clear, lag-free conversations - no need to rush to the door.
The DB2 doubles as a Bluetooth 5.0 gateway, enabling extended range and stable communication with compatible TTLock smart locks and other IoT devices. (Note: Full gateway features require future firmware update via TTLock App)
→ Build a unified smart home ecosystem without extra hubs.
Powered by two 18650 rechargeable lithium batteries, the DB2 offers months of operation on a single charge. Recharge conveniently via USB Type-C - no hardwiring needed.
IP54-rated housing withstands rain, dust, and temperature extremes (-10°C to 45°C). Mounts in minutes with included bracket - ideal for front doors, garages, backyards, and offices.

Q: Does it work without Wi-Fi?
A: No. The DB2 requires a 2.4GHz Wi-Fi network for remote viewing and alerts. Bluetooth is used only for local device pairing and future smart lock relay.
Q: Can I use it with Alexa or Google Assistant?
A: Currently, the DB2 is optimized for the TTLock App. Integration with voice assistants may be added in future updates.
Q: How long does the battery last?
A: Under normal usage (5-10 events/day), batteries last 3-6 months. Frequent motion triggers or live views reduce battery life.
Q: Is cloud storage mandatory?
A: No. You can use only the TF card if preferred. Cloud is optional for remote backup and playback.
