NVRs - Embedded vs Separate PoE Switch (Statistics)
Many NVRs now offer PoE switches embedded, allowing IP cameras to be connected directly to the recorder.
On the plus side, these units can simplify installation as it eliminates the traditionally used separate PoE switch as well as allows adding surveillance specific features. On the other hand, these embedded switches often lack full management features found in switches (PoE control and monitoring, SNMP, and more).
150+ integrators told IPVM what their preferences here, answering:
When using NVR appliances, do you prefer the PoE switch to be embedded in the NVR or to have the PoE switch separate from the NVR? Why?
Integrator responses revealed a split amongst three options, with separate PoE switches leading the way:
The largest segment of integrators preferred separate PoE switches...
Given the relative scarcity of Embedded NVR’s with more than 16 ports of POE, I wonder if another way to look at this is “Most Integrators prefer Embedded POE systems when possible.”
PoE switch and NVR separate. For my last project I purchased 7732 nvr's with 2 lans and no embedded switch. Finally, I don't need to pay for the switch I don't use.
the reason is control that managed switch provide and snmp: you can monitor the switch port and collect statistics from your device as well. Hik NVR's have snmp support but not too many parameters can be monitored
