Reolink D340B with Hub 1 is a wireless battery doorbell camera system designed for front-door monitoring. The 1:1 aspect ratio delivers a head-to-toe 150°x150°x180° view in 4MP (2K) HD, while dual-band 2.4/5 GHz Wi‑Fi keeps the device connected. The system supports smart detection for people, vehicles and packages, instant push notifications and video calls when the doorbell is pressed. The included hub acts as a storage, alarm and management center for a DIY camera setup and comes with a 128 GB microSD card included.

Local encrypted storage is available without ongoing subscription fees, with two microSD slots that expand storage up to 2×512 GB. Power options include a rechargeable battery or hardwiring to existing doorbell wiring (8–24 V, 5 VA–40 VA) and the hardwire option supports mechanical chimes. Smart detection reduces false alerts and sends instant notifications; visitor presses trigger push alerts and optional live video call.
