Thank you very much for your question. Our monitor supports IOS and Android systems. We have our own software, so you can rest assured to use it. 

1.If the camera's current Wi-Fi and Wi-Fi you want to switch can be connected at the same time, you can switch Wi-Fi directly by selecting Wi-Fi network in the settings interface. 2.When the camera is disconnected from the current WiFi, the app will display "Device disconnected". Click Troubleshoot to connect directly to another wireless network. Or remove the camera from the Tuya Smart and then connect the camera to the Wi-Fi you want to switch to.

The camera does not have an on/off switch. If you want to switch them off completely, you have to disconnect them from the power supply (e.g. when not in use) but you can also leave them plugged in. 

Each baby monitor is attached closely with a protective film to prevent scratches. You could try to buckle the four corners of the screen with your nails until it appears a gap. Then grab the gap and tear off the protective film(The specific operation is shown in the video).
