No, this camera does not support wifi connection. 

It HAS an Auto Focus button. Works great! As for the Anti-vibration/shake, NO, not that I can see. However, a hand stabilizer handle should help with that. I haven't notice any vibrations although I'm still experimenting. Beautiful video! FYI,Can't find an external monitor that works with this camera. Purchased two different monitors and five different HDMI Cables, No luck. But the flip out built-in is fine. Good quality, I just wanted something larger. 

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. 

You can view photos and videos from this WiFi trail camera without removing it from the mount. And you can set the camera in the APP. This is very useful for cameras mounted in high places or hard-to-reach places.
