Purchased this camera to add to an existing Onwote IP Camera system, works just like the ones sent with the system. Someone else wrote a review saying Power Over Ethernet (POE) did not work, this is incorrect, POE does work just like the others if connecting directly to the Onwote NVR system, if connecting to a switch or hub then you would need to ensure the port you are using is POE capable and enabled, or purchase a POE injector separately to install inline to power the camera. Works without any issues, plug and play to an existing Onwote NVR system.
