Can the camera work with mobile Phone's Hotspot?

Yes. In this way, you need to have two mobile phones, one phone as WiFi router, another phone to pair the camera to mobile phone's hotspot.

Warm tips:
1. WiFi frequency please select 2.4Ghz WiFi if the mobile phone's hotspot has both of 2.4G and 5G WiFi frequency.
2. WiFi encryption please select WPA2-PSK(AES).
3. In order to make camera stay connected with phone's hotspot, the phone's hotspot must be running all the time, otherwise, the camera will go to offline.
