The question isn't IF I'm getting an NVR, it's WHICH one.Try an NVR. If your the IT guy and your buddy wants the Easy button. Start there.
@Teken: Bro, that's some first rate helpful info right there!LOL - Apologies I should have tempered my reply for the average person with respect to force protection.
Regardless, physically isolating the security video from the main network also insures zero impact while using other services that consume high bandwidth data such as streaming services.
Nothing is worse than trying to surf the Net and pages don’t load because the security video feed is sucking up all the bandwidth in the home! You’ll read about people who set the frame rate, bit rate, secondary streams at the lowest settings through out the net.
Because their network wasn’t planned for with the eye toward expansion and increased bandwidth never mind storage or computational power.
As noted a (budget) dictates what can be done and the direction headed. None of us are made of money so like you must find a balance / compromise in some things we do.
Back on topic: NVR vs PC this really comes down to long term goals and intent. A NVR by its very nature is plug & play and you know it’s going to work. But you can’t upgrade anything if wanted never mind repair if broken within reason.
A PC can be upgraded and repaired any time by swapping parts. You have the ability to use any software that meets your needs either now or later.
There’s nothing wrong in running both either just because to get a feel or to learn. But unless you spend lots of money on the top of the line NVR none of them support 4K resolution on every channel. Even when you do spend gobs of money the bulk of them restrict a number of channels for AI, 4K, etc.
In 2021 there is zero reason having to compromise viewing at the minimum 16 channels in 4K! But manufacturers think it’s OK to view a 4K feed in 1080P!!!
Lastly, I don’t know if energy consumption matters to you at all. But what ever hardware you decide upon take a hard look at what each piece of gear consumes. You don’t want to find out your electricity bill went up 20% just to record the grass and side walk.
I never thought about the bandwidth issue in regards to LAN segregation. I'll add that to the "must do" side of the list for sure.
If this was my system, I'd be going the PC with Blue Iris route without any question. However, with this being essentially an off-site, set-and-forget (to the degree possible) install, I have to choose equipment and/or software that will help me meet that goal the best we can, within the budget. I haven't mentioned any specific budget, because the client hasn't given me one. He just told me to get decent equipment without going crazy. Helpful, huh?
He's not concerned with 4k streaming, or the ability to run 16+ cams. His house and grounds aren't that large, and he's not looking to have full eyes-on coverage of every square inch. Again, we get back to "good enough". Remember for those of us in the casual security camp, a couple cameras of reasonable resolution and a basic NVR to record any major events is plenty.
I did talk to my friend last night, and he agreed to take a more active role in things. He's agreed to try out one camera at first, to check sight lines and angles. That should give us a good idea of what cameras to add later. Thanks to everyone who suggested that idea. I really didn't think he'd be willing to jump in that deep.
