# Noorio App FAQ: Smart Hub & Sensors

# Smart Hub & Sensors

## How many devices can the Smart Hub support?

Up to **4 cameras and 64 sensors**. The Hub performs best with **4 or fewer cameras**. Sensors work only when connected to a Hub.

## Which models work with the Hub?

Currently: **B200, B210, B211, B310, B311, D110**, and the **H200 / H300** sensors. Other models are not supported yet.

## How do I set up the Smart Hub?

- Connect your phone to **2.4 GHz** Wi-Fi (the Hub is 2.4 GHz only).

- Plug in the **power** and **Ethernet** cables — a solid red light means power is on.

- Press and hold the reset/SYNC button ~10 seconds (or 2–5 seconds on short-press models) until you hear a prompt or see the blue light blink.

- In the app, scan the QR code → **Next**, select a group, name it, enter your Wi-Fi password, and tap **Next**. When pairing completes, the blue light stays solid.

## How do I switch the Hub from wired to Wi-Fi?

Hub Settings → **Network Settings → Change Wi-Fi Network** → select your 2.4 GHz Wi-Fi → enter password → Connect. After "Wi-Fi connection successful," unplug the Ethernet cable.

## How do I connect a camera to the Hub?

- **New camera:** during the "Connect to Network" step, choose **Hub**. Keep the camera and Hub in the same location group.

- **Existing camera:** Device Settings → **Network → Change Wi-Fi Network → Hub**. Keep them in the same location group.

## The sensor LED doesn't flash after I install the battery

Contact and motion sensors have no SYNC button — they broadcast once a battery is inserted. Remove the battery's protective film and reinstall it, confirm correct orientation, and replace the battery if it's low. If it still doesn't work, contact **support@nooriolife.com**.

## Hub configuration update

The latest firmware supports one-click Hub network configuration. The original soft-AP method still works: after the Hub is online, double-click the Hub SYNC button, then long-press the camera to configure it directly (no app needed).
