FAQ
Yes — as long as the NVR has enough incoming bandwidth and you optimize camera bitrates using H.265+.
Most models include 16 PoE ports, but for the full 32 you’ll typically add an external PoE switch for power and data.
Cross-brand camera compatibility, especially when the NVR supports ONVIF Profile S and RTSP.
It can work, but 2–4 HDD interfaces with 16TB+ support is strongly recommended for long retention in 24/7 builds.
Yes — NVRs record locally offline. Internet is only required for remote access and firmware updates.
