Hello, yes. The rear camera is waterproof. You can install it outside. 

It will NOT track the moving objects when motion detected. Just APP notifications push, spotlights and siren alarms, depend on your settings. 

First of all, make sure the camera is in a connectable state, in which case, the LED status light will show green or flashing red(flashing red indicates power low, but you can still connect to it before the power runs out). Please make sure you allow ATLI Cam App permission to connect Wi-Fi. Please turn off VPN on a smart device when connecting or using the camera. 

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.
