No, this camera does not support wifi connection. 

Yes you can. In fact that is what I am doing right now. The one that came with the telescope was alright but the camera tripod I have is a Polaroid and works much better. 

(1)Please check to make sure you have installed 1.5V 6*AA battery. Do not use inferior batteries as their voltage is lower than 1.5V. (We recommend brands like Energizer, Duracell, AmazonBasics, etc.). (2)Make sure the polarity is correct and the contact with the spring is normal. (3)Press and hold the power button for at least 3 seconds to power on. (4)If it still cannot be turned on after 1-3 steps, please try to use a power bank. 

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. 

1.If the camera's current Wi-Fi and the 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 show "Device disconnected". Click Troubleshoot to connect directly to a different wireless network. Or remove the camera from Tuya Smart and then connect the camera to the Wi-Fi you want to switch to.
