Had an issue with the camera while attempting to setup up a vlan. Several other cameras worked properly, however, after several hour down the rabbit hole, decided to update firmware on camera. Wrong firmware, and asfar as I can tell, there is no updated firmware for this particular camera. Was able to recover camera and able to utilize. The only issue, Zoom and focus works, but unable to see image while zooming and focus. Model # on the camera IPC-HFW2231TP-ZS. Thanks!!
