Resetting the camera
For most of the cameras mentioned, there is a reset button at the back of the camera.

Steps to reset the camera:
- Reboot/power cycle the camera by disconnecting the power source (Ethernet for PoE and power adapter for non-PoE) and then plugging it back.
- Within 10 seconds of powering up the camera, press and hold the reset button for 10 seconds.
