I know I'm moving myself into a danger zone by stating the following: it depends. My own first "personal" project, I opted for an NVR (5216-16P-4KS2) from
@EMPIRETECANDY. Price around $300. But having this POE NVR, eliminated already $150+ 16 port POE switch (or 2 times 8 port POE switch) - including cabling etc. Plus another advantage that the NVR "auto-routes" traffic for each POE-cam so you can access the cams individually (through the NVR), just like a 2NIC BI pc would do, with additional software configuration). I only added a 2TB disk I had flying around, but that's not the money.
Was this an easy choice? No, NVR GUI's are terrible (eg some features are to be configured in the cam (eg iFrame settings), some features are propagated between CAM & NVR (eg IVS etc)). But you get an "all-in-one" experience - especially with Dahua (and NVR & IPC's on dahua): once you set it up, you download free iDMSS/gDMSS, you toggle push notifications and off you go. For $300. To that NVR, I added video doorbells and automatic doors. All through the same app. Performance wise, the NVR can handle the load with two fingers in the nose. And the misses can use it blindly on her phone, am I a lucky bastard.
For another project, we evaluated BI. I must admit: lots of features! But without reading all the help, you get lost in the configuration settings. You need to be a BI expert.
Your bill of material becomes:
- you need the pc hardware (like

- you need windows license ($20?)
- you need BI license (now in sale: $49.99)
- you need the networking hardware (count $100-$150)
- you need to pay for mobile app ($9.99)
Adding up almost gives the same amount, much more "freedom in configuration" and "upgradability" but the misses was not impressed by the interfaces.
But like I said: some like BI once they see it, some don't. So bottom-line, my advice to you: evaluate BI. See for yourself. If you're into twiggling each feature, go for it.
Hope my 2 cents help you out a bit,
