Important
Standard Non-PoE Recorder
The NVR508-64B does not include built-in PoE camera ports. All IP cameras must connect through compatible external PoE switches or the existing network infrastructure.
This is the standard NVR508-64B and should not be confused with the NVR508-64E-IQ, NVR508-64E-R, or NVR508-64E-R-IQ models.
