For someone wanting a camera sysytem for home use and who has little to no experience with a NVR security system, is it better to go with a Dahua NVR with built in PoE, or should I look at a NVR with a seperate PoE switch? I want to take advantage of the cameras IVS features such as tripwire. Can I set up and use all the features of Dahua IVS / smart cameras with the Dahua NVR5216-16P-4KS2E with a built in PoE?
