When defaulting recorder in this way and there are PoE cameras that were initialized by the recorder, the cameras will also need to be reset. This is because the cameras password is set to the recorders password.

Some models have a button fitted to the PCB, but it does not perform a factory reset. For example, the NVR4PRO3 includes a PCB button that is non-functional and cannot be used to reset the recorder.

- Remove the lid of the recorder, then press and hold down the reset button, while holding the button down turn, the recorder power on.
