Hello Neighbor!
Yes this forum has been amazing so far. Glad I found it. There is so much that goes into selecting and setting up a system on your own. Should have left it up to the experts but my stubborn self wanted to go with a system/brand that my installer isn’t familiar with so having to learn on my own! I’m getting there!

Be glad you didn't go with "experts". Most will install a "big box" solution with wide angle views that are useless for identification and small sensors that won't work well at night. Learning and doing it yourself will produce a system that actually works and provides useful video and probably at a fraction of what those "experts" would charge. Go with a low priced "expert" and you get a trunk slammer to top it all off.

actually all he installs is Dahua. But all he does are the standard 16 channel 4mp 12 camera kit that they sell. I wanted AI features and 2 way audio. So I decided to get the equipment on my own so I could get features I wanted and he agreed to just do the labor of the install but I would do everything else since I went with Hikvision. I see around here Dahua seems to be the preferred brand. Lol oh well, I’m already in too deep to switch.

If you're i the Hikvision box, stay with Hikvision. Using an NVR is a little limiting in terms of AI though. A full featured NVR with enough bandwidth and processor to supply all cameras can get really expensive really fast.
with the 12 acusense cameras I have, I should be okay with the acusense NVR as far as bandwidth. Now if I go adding more cameras there may be an issue. But yes this little project has cost me way more than I initially expected. But if I’m going to do it, may as well do it how I want or it won’t serve its purpose in the first place. Maybe eventually I will learn enough to where I can switch to BI but for now I think I should be able to accomplish what I want.

There are many variations of Acusense NVRs. I'm not an NVR user but I do know that without enough bandwidth capability ad without enough processing capability you can be sorely surprised. I urge a lot of caution regarding the specific model of NVR. Maybe a Hikvision NVR expert can chime in here with some really solid advice concerning the specific models and their capabilities. For example, a basic Acusense NVR might handle four 4MP cameras and one or two with AI while a higher end one may handle up to eight or more of each. As I said, I'm not an NVR expert but I have seen many disappointed people here when the under size the NVR capabilities.
So the NVR I got has max incoming at 160 mbps. The cameras say the bit rate could go up to 8 mbps. So at 12 cameras at the 8mbps I should be good I think. Unless I’m not understanding something which is totally possible lol.
I did not look into processing speed so guess I need to go look into that now too.
Addresses given out at random is not the norm in my experience but your router doesn't seem particularly normal to begin with.
Either way is definitely a suitable method.Not saying that "reserving an IP" or "making an IP reservation" in a router is a bad practice, it works...just saying that if the router doesn't provide it OR you care to do it as I stated (use IP's that are OUTSIDE of the router's DHCP pool), then no worries, it's not an issue.
It really comes down to personal preference and ease of configuration in your router.
For me I prefer to have my devices remain on dhcp rather than statically assigning addresses.
Ask him for the model numbers he installs and post them here.... and I suspect they will be 5MP or some other non-standard poor MP/sensor ratio.
We have seen many come here after having a professional Dahua install because they are disappointed in the picture quality at night, and many end up swapping out with different cameras that we recommend here.
Which model number did you end up going with? Incoming/outgoing make a difference. Most go with an NVR with 320Mbps. And some here have to run 4 NVRs to achieve the quality they want.
So thought I was in another jamb. Realized that there were 2 different spec sheets for the NVR I got from B&H. One from us.hikvision and one from main hikvision. Us one doesn’t have face capture. One feature I was interested in for at least one camera. And funny you say this, yes ordered a 5mp turret and again it’s specs say no face capture but since I thought NVR could do it, thought no biggie. Typical US thing. Remove a cool feature and charge more for it in the IDS NVR. So was freaking out thinking I had to return NVR or cameras. But after looking again, I now see cameras with same features I wanted as well as face capture on the camera in a 4mp. So think I will just swap out the cameras.
attached is standard budget Dahua kit installer only installs.
then the confusing NVR with 2 different specs
Then 5mp I ordered and 4 MP I am going to swap out with and return the 5 mp.
Boy what a stressful day
NVR DS-7616NXI-I2 16P S
sending back PCI-T15F2SL
and getting DS-2CD2347G2-LSU/SL
So mine says 160 mbps. The next one up, the $2700 32 channel deep in mind version, , has 320 Mbps. But I did see on Dahua NVR that had 320 Mbps it stated that when in AI mode its max was 160 Mbps. No way I want to spend 3k on an NVR right now lol
LOL - it is why most of us go to BI! In addition to way more flexibility, it is cheaper than a capable NVR!
10.0.01-10.0.0.255 is just another private ip address pool
there are 17,065,000 different private IP addresses that can be used on a ipV4 private network.
The private nets has to be an address in these 3 sets:
10.0.0.0 to 10.255.255.255
172.16.0.0 to 172.31.255.255
192.168.0.0 to 192.168.255.255
It just amazes me that the US will take a perfectly capable international NVR and cameras, remove the face recognition and face capture features, and then charge a premium price and force you to purchase a 3k NVR when the other side of the world gets those features in the regular acusense series. Gold ole USA wanting to charge a heft premium. Sickening
So I got my new modem/router finally and set it up. Logged into it online and very easily saw where I could reserve the ip address. Also was pretty neat, all of my devices on the new router kept all the same Ip addresses as the old one. But question is, so “reserving” the IP address will ensure it never changes the same as setting static and changing the Pool? Just wanted to make sure I understood if there were any differences between the 2 methods I need to be aware of. May test both methods on a device.

If you want to change tack and send everything back, my recommendation based on the forums preferences would be a pc running BI connected to either 4kx or 5442 cameras (Andy a fourm member and owner of empire Tech - it#s his model numbers for the Dahua OEM versions he sells. You can find the Dahua numbers on this forum if you want to source them from elsewhere as non oem). Those 2 cameras will offer you the best picture quality at reasonable prices right now. There's also a 4k-t turret version of the 4kx although it's a little new to recommend it yet in my opinion. The 4kx will give you the best colour at night but requires a little light. The 5442 offers better performance in no light or very very low light either through ir or forced colour.
I have actually been reading up on BI here today
I have already had to send back 5 cameras and get some different ones. Haven’t even hooked everything up yet, was waiting to change out my modem. So what I do see happening is getting used to this NVR and cameras and learn a little more about all of this. And maybe once Iget comfortable, switch to a PC set up 6 months from now or whatever. I don’t have the tech knowledge quite yet to feel comfortable doing the BI set up at this point at least. Knowing myself though, it’s a very high probability I will see it in my near future.
