TL;DR
Most security cameras only work on 2.4 GHz Wi-Fi (not 5 GHz). If your router has both bands, make sure you're connecting to the 2.4 GHz network. The setup takes 3-5 minutes.
Why 2.4 GHz and Not 5 GHz?
| Feature | 2.4 GHz | 5 GHz |
|---|---|---|
| Range | Longer (through walls) | Shorter |
| Speed | Slower (sufficient for video) | Faster |
| Congestion | More crowded | Less crowded |
| Camera compatibility | ✅ Almost all | ❌ Most cameras don't support |
Security cameras prioritize range and wall penetration over raw speed — 2.4 GHz is the right choice.
Step-by-Step Setup
Step 1: Check Your Router
Most modern routers are dual-band (both 2.4 GHz and 5 GHz). Check your Wi-Fi network names:
- If you see one name → the router auto-selects the band (usually fine)
- If you see two names (e.g., "HomeWiFi" and "HomeWiFi-5G") → connect to the non-5G one
Step 2: Download the App
Depending on your camera model:
- YI IoT (most common)
- YI Smart
- ZKcam Pro
All available free on iOS App Store and Google Play Store.
Step 3: Add the Camera
- Open the app and create an account
- Tap "+" or "Add Device"
- Select your camera model
- Connect your phone to 2.4 GHz Wi-Fi
- Enter your Wi-Fi password
- The app generates a QR code — hold it in front of the camera
- Wait for the camera to connect (30-60 seconds)
Step 4: Position and Test
- Place the camera in desired location
- Check live feed quality
- Test pan/tilt (if applicable)
- Verify night vision
- Insert TF/microSD card for recording
Troubleshooting
| Problem | Solution |
|---|---|
| Camera won't connect | Ensure phone is on 2.4 GHz, not 5 GHz |
| QR code not scanning | Increase phone brightness, reduce distance |
| Connection drops | Move camera closer to router, check signal |
| "Network not supported" | Your router may be 5 GHz only — enable 2.4 GHz |
| Slow live feed | Reduce video quality in app settings |
FAQ
Q: My router only shows one Wi-Fi name. How do I know it's 2.4 GHz?
A: If your camera connects successfully, it's using 2.4 GHz. If it fails, log into your router admin panel and ensure 2.4 GHz is enabled.
Q: Can I use a Wi-Fi extender?
A: Yes. A 2.4 GHz Wi-Fi extender can improve signal for cameras far from the router.
Q: How many cameras can one router handle?
A: Most home routers support 10-20 devices. Three security cameras use minimal bandwidth and won't cause issues.
