We've got some locations that are hard to get power to, so we want to go with 4G, solar cameras. IPC-HFW2431DG-4G-SP-EAU-B - Dahua CEE Region (dahuasecurity.com). I know these can take an SD card for recording, but how can you add a camera to an NVR if it is not on the local network?
Add 4G Camera to NVR
- Thread starter techpros
- Start date
When a POE camera is plugged into a POE port of a POE NVR, the NVR places that cam on a private network to isolate it from the LAN and the Internet.
You can give a IP camera a unique, static IP in a chosen private subnet, such as 192.168.1.XXX, and connect it via a POE switch that is connected to the NVR's LAN; the NVR's LAN should also have a unique, static IP in the same subnet as the IP camera.
Hi. Thanks for the response. I understand that on a private network, no problem. But what if it is a stand alone camera connecting to the internet over the 4G network. There is no LAN. Can you use P2P for example to add to the camera to an NVR?
Yes, you’ll probably have to use p2p. As you said you have no lan to work with and cellular ips charge constantly. Once it’s online just enter serial into nvr camera list/manually add.

One thing to consider is data, truly unlimited cellular plan or compress the crap out of it.
My bad. By "local network" I thought the NVR was POE and was on site with the cam and the cam was not POE....got it now (duh).
Definitely doable, this guy has about 100 cameras over 8 sites around KC that I have piped into his “command center!” Those displays cycle through every 5 seconds. A few were cellular routers to nvrs and a couple were cellular cams. 
There are two ways to do this.
1. The cell carrier can assign an IP address to the sim card. This is usually an added cost. Then you would just put in the IP address, port number, user name and password when adding to the NVR.
2. Make sure camera and NVR are the same manufacturer and is compatible. If so then you will be able to add it in without IP address. On Hikvision units it is called ISUP/OTAP. I would assume Dahua has a similar feature.

Modern Dahua NVR's (like 5xxx-EI) have capability to add cams over P2P.
Enable P2P on 4G cam, put any internet SIM card (best without public IP to hide cam), copy cam serial number (from P2P menu).
Then do MANUAL add on NVR UI (web or HDMI), change type from PRIVATE to REGISTER (if I remember name correctly), cam IP address will be replaced by serial number field where You put cam P2P serial number... fill user & password, click add, should work..
Hey guys, can someone advise me on how it is possible to live stream multiple cameras onto a private website and app. The cameras will be at different locations many miles apart, they will have to be LTE, solar/battery back up powered, no Poe. Is this possible and if so how?
Would love to understand this too! I know next to nothing. In my specific case, I bought a Sehmua 4G LTE Solar Powered camera (without doing much research) and have it running through their app, but would prefer to host the live stream on my own website. The camera doesn't run on my wifi network, so stuck at the step of just trying to find it on my onvif device manager software. Again, this is unfortunately not remotely my expertise but would love any advice.

Depending on manufacturer, for example Hikvision hik partner pro offer Developer apikey and app secret and you can fetch stream via their SDK over cloud without opening ports on 4G sim card. Then you create a small service converting that stream to RTSP or RTMP protocol and push to your website.
Or use directly a service within your website to fetch stream via SDK and presenting it on page. Of course this would require you to use something like ASP.NET over other done solutions.
