Sometimes I heard the X1/X1-Lite make two “click” sounds and saw it turning its head on its own. Should I be concerned? Is my camera hacked?

No. The X1 has a scheduled restart routine every once in a while, and this is the X1 performing a regular hardware check after it restarts. The “click” sounds come from testing toggling the Night Vision lens, and the turning is from testing the motor.
