Having reviewed the camera behaviour “as-is” then next step is to dismantle it, and see what can be learnt from the circuit board and chip choices. For an unknown device extra care should be taken to avoid any anti-tamper devices, however in this case, the device isn’t important and can be easily replaced if damaged.
