Key Notes

• This is a 32-channel NVR without PoE, unlike the 16-channel NVR5216-16P-EI which has PoE.

• AI features are slightly limited compared to the larger 32-channel NVR5432-EI (fewer AI channels and face databases).

• Max bandwidth is lower (256 Mbps vs 384 Mbps).

• Best suited for setups where cameras already have PoE injectors or separate PoE switches.
