If you are looking for a 4 channel NVR, Channel Vision now has the NVR-04N with built in POE. This would be the best option. If you require an NVR with more than 4 channels, we are a camera partner with the NVR manufacturer QNAP and we do integrate with their NVR’s as well. Beyond this our cameras will integrate with most NVR’s that support ONVIF streaming. Please be aware that any ONVIF integration will not allow for motion recording, so this is primarily used when recording 24/7.
