You don't need to buy a new router. Buy a Raspberry Pi and install OpenVPN and / or WireGuard on it. Plug the RPi into your router. Create the relevant VPN profiles and copy them to your mobile device such as iPhone. When out and not connected to your LAN, connect to the VPN on the iPhone and you can access the cameras via DMSS. I have a NVR and it all works very well. I have P2P turned off.

I have two RPIs - they are each plugged into my main switch which in turn is plugged into my Router (Unifi USG-Pro4).

Hello, I’ve been reading through this thread but haven’t seen anything mentioned about configuring SD card as back up storage. I’m using a new 5216-16p with 6 TB Purple HD from Andy and the interface looks a lot different than my older 5208-8p. I haven’t seen anything related to the SD cards in NVR storage, maybe I need to log into each camera? I’ve noticed IVS setup thru NVR is hit or miss, I assume better through camera?

Also, anyone using the new Ai features face recognition ect over tripwire, intrusion & others?

Thanks for any help!

Yes you would configure SD card storage on each camera. And yes as mentioned it’s best to make ALL settings on the camera especially IVS rules.

I’ve used Face Detection successfully, (not face recognition which is much more advanced and tricky) and others have had success with scene changing.

Agsin recommend you first make settings on the camera and allow it to push back to the NVR.

I think for the cost of a new Raspberry Pi I can buy a decent new Asus router that has OpenVPN and DDNS built in and bridge my Amplifi HD mesh network to it. My house is too large and has several dead spots to not use a mesh setup.

I’m going to buy a second router (Asus) and use with my setup as it’ll have DDNS and built-in VPN as my existing Amplifi HD mesh system has neither. This will cost at most the same as a Raspberry Pi with OpenVPN loaded onto it for remote NVR access connection. The question I have can the new ASUS router sit behind my Amplifi router in bridge mode and the NVR can connect to the Asus router through OpenVPN? Or is Asus router in bridge mode and sitting behind the Amplifi router going to prevent OpenVPN or DDNS to be used? If so, this would mean the Amplifi router would need to sit behind the Asus router in bridge mode and the NVR connected to the Asus router. I have a lot of square footage and dead zones so I need to keep the Amplifi router in the network but it’s also not giving me 100% coverage which I could address with a second router.

First off I hope it's ok to resurrect an older thread here, but I would like to just give a shout out to bigredfish for this excellent guide on the first page. I WISH it came as the actual instructions instead of the dahua wiki stuff as I wasted hours trying to figure out configtool, networking, IP addresses, passwords, etc.

I bought a NVR5208-8P-4KS2E from Andy and over the years have purchased 4 (soon to be 5) T5442T cameras, which I have found to be just excellent all around. I previously was using an older PC with Blue Iris and separate switch, but I grew tired of updating and just working in BI in general.

My issue is I followed the guide, the cameras were added automagically, everything was good. However, I didn't realize I put them in ports 1 3 5 7, so on the mobile app I was seeing empty screens (2, 4). So I thought I would just move 5 and 7 to 2 and 4 and that's where the problems started.

The NVR found the new ones, also duplicated one, and they no longer just connect automatically. They are currently in the top pane, the live view works, but I don't want to 'add' to the bottom pane because then I don't get port2, port3, etc. I've waited all day for them to move down by themselves but no luck.

My questions:
Is my only recourse to hard reset the NVR again and add them all again, this time to the correct ports?

Also I could try to reset the cameras but I don't believe I found the correct process - I've tried unplugging the power, holding reset button for 30 secs, but the camera password does not clear. Does anyone know the correct method to truly reset the T5442T cameras?

Thanks for any insight!

Did you delete them from the bottom screen after unplugging them and before plugging them back into the new ports?

I would simply log into each camera, set them for DHCP, save, and reboot each one then wait and refresh bottom pane . I’ve successfully switched ports that way

DO NOT follow instructions telling you to use the config tool or switch the IP of your cameras or initialize anything..!

With NVR's typically with a -P designation (Built-n PoE switch - example: 4208-8P-4KS2) none of that is required and it will often make a mess of things.

If you have a Dahua NVR with built-in PoE switch

*On initial setup for the NVR and cameras, DO NOT enable P2P in the popup that asks you this. Uncheck that along with Auto updates.

1- Fire up NVR using a mouse and monitor to do the initial setup, security questions, password, leave default Networking/IP alone (Verify it is static IP at 192.168.1.108 - assuming a standard home network of 192.168.1.x ), If you wish you could change the NVR IP address to some other static number on the 192.168.1.x network, This might be helpful if you were to add other Dahua cameras later outside of the built in PoE ports via say an external PoE switch as Dahau cameras connected this way will also default to the .108 address and create a conflict. . (I like to use .254 as I’ve yet to see that get assigned randomly by the router DHCP pool in a normal home environment)

Then disconnect from the NVR and never go back to that machine interface. Dont try and make any other setting changes here. You can change it all later in the Web interface.

2- Plug in your cameras to the NVR. Dont do anything else. The beauty of a PoE NVR is you dont have to do a damn thing, just plug them in, dont go clicking on buttons and shit when you dont know what youre doing, It WILL F$@k things up.

*Dont try to manually add them or force them to the bottom pane. Wait. Sometimes it takes a bit.

3 Open a browser on a PC on your network (again assuming a standard home network of 192.168.1.x) and type 192.168.1.108 or the IP you changed it to, and hit Enter. You will go to the WebGUI interface of your NVR. This is how you will manage your NVR from now on. Login with the name and pass you assigned the NVR

4- Assuming the newer 4.0 dark interface, Choose "Management" at top left then "Camera". This will take you to a page (Registration) that looks like the thumbnail below. The NVR will have automagically assigned each camera a channel and an IP address in the 10.1.1.x range** and a port of 1,2,3 etc.. You can NOT access the cameras without going through the NVR interface and using the Blue IE icons. See thumbnail below. (well you can access them but its a PIA and not necessary)

5- Click on the BLUE IE icon to open the individual cameras Web GUI to make changes to your camera settings, IVS, etc. The login for each new camera will default to Admin/your NVR password
The Login and Password for each camera will be identical and the same as your NVR. Dont F$@K with them!
*On initial login/setup for the cameras, DO NOT enable P2P in the popup that asks you this. Uncheck that along with Auto updates.

View attachment 58246

* It seems some older cameras and/or cameras that had already been initialized with another NVR, may retain their "old" password, but new Dahua cams out of the box will assume the same login credentials of the NVR via synching.
If you see a red dot next to a camera, and/or a gray IE icon that does not open the camera GUI in a new window as expected, its likely that the password on the camera is different than that of the NVR. If so, using the "pencil" icon, edit the password information for that camera to the password you may have previously set on another NVR or installation.

*The Edit dialog does not change anything on the camera. It simply allows you to edit the information of the camera that the NVR uses to communicate with the camera.

Notes

A -When you go to the camera registration page, do not try and add cameras attached to the built-in PoE ports manually to move them from the top pane to the bottom. Let the NVR do it automagically, May need to unplug them and reboot once. WAIT! It may take a few minutes for them to appear in the bottom pane. DO NOT be tempted to manually add them or move them from top to bottom panes.

If the camera does move to the bottom and is assigned a correct 10.1.1.x address but you continue to get a red indicator, another option is to open the camera access panel, and while still connected to the NVR, press and hold the reset button for 30 seconds. Then unplug it, delete the entry from the registration page, and plug it back in.

B- If using a Dahua NVR with the bullt in Poe switch, cameras using the built in PoE ports and showing port 37777* can’t be reached via the interface (IE button) as noted. Usually see this if you try to add them manually from the top pane to the bottom. (Or if you are using a splitter or extender and trying to run multiple cameras off of One PoE port. I dont recommend it) If you let the NVR assign and pass credentials by itself, they’ll show up as port 1,2,3 etc and you’ll be able to access them via the IE button

*UPDATED:
When using the built-in PoE ports, the NVR will assign them an IP (10.1.1.x) and a local port (1,2,3) and they will automatically populate the bottom pane as described above. You cant add them manually or it will mess up.

On cameras connected via external switch (like the ones shown at 192.168.1.x in the thumbnail below) you search for them in the top pane, and then have to add them to the bottom manually. These cameras connected via external switch will use port 37777. These you need to add one at a time and login to the camera and assign it an IP other than 192.168.1.108 as that is the default IP for all Dahua cams. Then add another and assign it another IP and so on, one at a time.

Also, cameras using an external switch CAN be accessed directly via their IP address.

C- I’ve found it works best not to mess with any settings other than Network and Recording schedule on the NVR. I make all Image, Exposure, Event, and FPS/Bitrate changes on the camera itself >>>> and it pushes them to the NVR fine. Making image and Event changes on the NVR does not always push them correctly to the camera however.

D- For day to day viewing/playback and downloading of clips on your home network, simply download and install Dahua SmartPSS on a computer on that network and use it. This is simpler and better than trying to use the NVR web interface all the time just to view cameras or download footage. That said, dont try and use SmartPSS to adjust or mange the camera image or Event/MD/IVS settings Do this on the camera itself.

E) Note: Its best to limit changes to Image, Encoding, Bitrate/FPS, IVS, Motion Detection, etc to one device or the other, I recommend using the camera interface. If you make some changes on the camera and others on the NVR, it will mess up something eventually



Questions:

Does the pencil icon pop-up on the nvr camera registration page modify the camera password or is that only so you can login into the cam?
It just allows you to enter the proper credentials already on the camera for the NVR to communicate with the camera, it does not modify the login/password of the camera

You said when you plug a cam into the NVR it changes the camera password to the nvr password but i didnt' find this to be true.
On a new camera or one factory defaulted and using the built-in PoE ports on the NVR, I can assure you it assigns the NVR password to the camera. If you have changed the camera settings somehow directly, installed the camera on another NVR previously, changed the IP or messed with onvif or ports, it may not adopt the NVR credentials and you may need to A) use the "old" password you originally set for the camera, or B) factory default the camera and start over.

If my cameras are now on the NVR private network of 10.1.1.x how can I view them without going through the NVR interface first?
The same way you would with an NVR without built-in PoE ports. By using SmartPSS (desktop), or the Dahua Mobile apps DMSS, iDMSS or gDMSS. They will "see through" the NVR to allow you to view your cameras. Remember, use these apps to view and download video clips. If you want to make changes to the Image, Events etc, do it on the camera itself.

Can I still use a VPN? Wont that be a problem again with the cameras on the 10.1.1.x network?
Yes. You will access them the same way as above. The VPN puts you inside your network as if you are sitting at your desk at home.

Interesting and thanks so much. I currently run 8 dahua cameras (mix of PTZ, stargazer and colour night time cameras) working with BlueIris. We are now selling our house and leaving the camera set up, but blue iris will be too complex to leave especially with the port forwarding required to access the cameras via the app. As a result, we want to get a budget dahua NVR. I assume the fact that all of our cameras work through our home intranet and our switch means we can literally plug in a Dahua NVR and assign each of the cameras IP addresses in the NVR and we would be good to go? I hope that the NVR doesnt require each camera to be direct connected to the NVR? Sorry for asking such basic questions, but I want to make sure it works for our application before I pull the trigger.

Also which NVR would you recommend as a budget 8 channel NVR with IOS app access? Am looking at the NVR5208 as a good budget one that does everything we need in terms of remote access, remote replay and motion alerts

Thanks in advance

Yep the 5000 series are the best value workhorse.
And yes you can use an external switch and assign each an IP on your LAN and manually add them to the NVR

Amazing - thanks for the fast response. I was looking at the NVR5816. I was also looking at the newer style Dahua: VCR Nvr IP Dahua 4K 8MPX 16 Channels IP Ultrahd but I can't find much on these. I think they may be better in terms of AI and app integration, but would be great to get views before I pull the trigger. It is key that there is remote viewing and motion alerts via an iOS app, as well as reliability and good quality feeds from 8 cameras. Thanks in advance and thanks so much for your fast and informative response @bigredfish

All NVRs

The 5000 series. Assume 2HD is plenty for 8 cameras so the 52xx
Probably this 16 channel to allow for more cameras. 5216

If using an external switch you can ignore the models with -xxP- designation. Those have an onboard internal switch

The Wizsense series (2000 series) has a few more AI bells but only roughy 1/2 the incoming bandwidth and decoding

New question on SmartPSS, I'm unable to configure a video wall because I only see the 'default group' with nothing listed under it. I assume cameras (I have 5) should populate under that and then I drag them onto the grid diagram. The NVR is on my main network at 192.168.1.100 and the cameras are on the NVRs network of 10.1.1.X.
The original instruction said SmartPSS will 'see through' the NVR to the cameras but I'm not finding that to be the case. Just having trouble actually viewing these in Smart PSS, although the tiny preview window works.
If anyone has some insight that would be appreciated.
Thank you

Not sure I understand. Have you added the NVR to SmartPSS under “Devices”?
If so do you show a green indicator?
If so your 10.1.1.x cameras should show
Yes the NVR is listed as the sole device on the 'Devices' screen. It is online and I now see the cameras in Live View, which wasn't working before. I still can't create a 'window' to use the video wall. When I go to create a new window, on the first step I add the correct number of screens and then on the next step there are no cameras listed to add to each screen. So I get the error 'failed to add video wall'. Seems like a weird quirk.

Perhaps I misunderstand what video wall is compared to Live View, although the manual doesn't really explain it much for me. At least I have live view working.

Honestly without your instructions in the first page I'm not sure how I would even have gotten this far, so thank you again!

I've never played with the Wall so cant help ya there.

Is someone here familiar with the "error config file"? I own an 4208-8p-4ks2 which gives me that error. I have got the most recent FW, so V4.0.

Factory reset and reset parameters didn't help.
