Hi there! I’m Emily. I’d be happy to help you get your XDV app connected to your Sencor 3CAM 4K04WR on your Xiaomi Redmi 12c running HyperOS.

To start, can you tell me a bit more about what happens when you try to connect the app to the camera? For example:
- Does the app show any error messages?
- Does it fail to detect the camera at all?
- Is the camera powered on and on the same Wi-Fi network as your phone?

Meanwhile, here are some initial steps to try with your setup:

1. Check Wi-Fi Connection
Make sure your Xiaomi phone is connected to the same Wi-Fi network that the Sencor camera uses. Sometimes cameras create their own hotspot; if so, connect your phone to that.

2. Restart Devices
Turn off and then turn back on both the camera and your phone. Sometimes a fresh connection helps.

3. App Permissions
On your Redmi 12c, go to Settings > Apps > XDV App > Permissions, and ensure the app has access to Wi-Fi, location, and storage as needed. Location permission is sometimes required for network scanning.

4. Update App and Firmware
Check that your XDV app is updated to the latest version in the Play Store or app source. Also, verify if the Sencor camera needs a firmware update (usually via the app or manufacturer’s website).

5. Network Settings
If your router has "AP Isolation" or guest network enabled, disable that temporarily to allow devices to see each other.

Let me know which of these you’ve tried already and what you observe when attempting to connect, and we’ll go further from there!

Still not working

Thanks for letting me know it’s still not connecting. Let’s try some deeper troubleshooting steps tailored for your Xiaomi Redmi 12c with HyperOS and the Sencor 3CAM 4K04WR using the XDV app.

1. Check Camera Connection Mode:
- Does your Sencor camera connect over Wi-Fi or does it have an Ethernet option? Make sure you know which network method it uses.
- If Wi-Fi, confirm whether it uses a direct hotspot mode or joins your home network. Your phone should connect to the exact same network.

2. Manually Add Camera in App:
- Open the XDV app and try manually adding the camera by entering the camera’s IP address.
- To find the camera’s IP: on your router’s connected devices list, look for the Sencor camera MAC or name.

3. Check for IP Conflicts and DHCP Settings:
- Sometimes cameras fail to connect if your router has IP address conflicts or strict DHCP lease limits.
- Restart your router and assign a static IP to your camera if possible in your router’s settings.

4. Firewall or Security Apps on Phone:
- Check if you have security or VPN apps running that might block local network discovery. Try disabling such apps temporarily and test the connection.

5. Reset Camera Network Settings:
- Refer to the camera’s user manual to reset its network settings (usually by holding a reset button for 10-15 seconds). Then, try setting it up again fresh with the app.

6. App Compatibility with HyperOS:
- Since HyperOS is relatively new, occasionally apps may have compatibility issues. If possible, try connecting the camera with another Android device or an iOS device to confirm if the issue is device-specific.

If these steps don’t work, I recommend contacting XDV support directly with your device and camera details at [email protected] for advanced troubleshooting or firmware-related issues.

Let me know how these go or if you need help walking through any of these steps! Are you satisfied with this plan so far?
