Hi there! It sounds like you're having a bit of trouble connecting your camera app to your phone. I’d love to help you get this sorted out. Can you provide me with a little more detail? For instance, what specific camera model are you using, and do you see any error messages when you try to connect?

In the meantime, here are a few general steps you can take to troubleshoot the connection:

1. Check Wi-Fi Connection: Make sure your iPhone is connected to a Wi-Fi network that is compatible with the camera. Many cameras, including V720 models, only support 2.4GHz Wi-Fi networks.

2. App Permissions: Ensure that the V720 app has the necessary permissions to access your camera and Wi-Fi settings. You can do this by going to your phone's Settings > Privacy > Camera and enabling it for the app.

3. Restart Your Devices: Sometimes, just a simple restart can resolve connectivity issues. Try rebooting both your iPhone and the camera.

4. Reinstall the App: If the app still doesn’t recognize the camera, consider deleting it and reinstalling it from the App Store.

5. Bind the Camera Again: Open the app and follow the instructions for adding a new camera. Make sure the camera is turned on and in binding mode.

Let me know if any of these steps help, or feel free to provide more details about the issue!
