Hello

I am planning on purchasing these cameras:


I have a home automation system which I'd like to live stream the cameras to. My system is running an Ubuntu server with node-red installed. My setup is viewed via an ipad tablet.

Do these cameras provide a HTML live stream? If so, I can integrate that into my nodered dashboard and display it on my ipad.

If not, then I understand there's an RTSP feed that needs to be decoded with VLC media player? Has anyone installed VLC on Ubuntu server? Or does it need a GUI interface?

I would avoid buying these cams .. they are quite old, not the best what you can get and all are 2.8mm ... this is useless in most cases. Also the price looks quite high to me.

Here are many recommendations which cams you should buy and why. Maybe read a bit.

Yeah, those cameras have a 1/3" sensor, while the current 4 MP sweet spot used by folks on here uses a 1/1.8" sensor. What that means is that the cameras you linked will have 1/4 of the light falling on the sensor, night vision will be poor.

I don't know anything about NVRs, but other folks on here do. @EMPIRETECANDY is a user on here who sells equipment and may be able to help. A lot of folks on here buy directly from Andy, including me.

I think the RTSP feed can be watched with just a web browser, I know it can be read with VLC and may other programs. I'm sure there is multiple ways to show it on a Linux server, but I don't know anything about them without a GUI.

It is Dahua, you can connect to the camera directly via a web page (ie a browser)

But I also might suggest avoiding the cameras shown in the URL you posted above. They do not seem to have any AI capabilities. AI has been a turning point in this industry and I would not setup a system without it. Either your NVR, your software or camera should have the ability to use AI. Maybe your “node-red” has AI? No idea, but Blue Iris Integrates directly with AI and it makes the system go from “I get a lot of alerts, but at least I know my system is operating” to “When I get an alert, I take action”

Welcome @ubntu

I concur with @user8963 @TVille @looney2ns here, and would recommend looking for better cameras.

HomeSeer has a Blue Iris plug in, allowing you to leverage or force trigger events in cameras.

Thanks for the responses! I am struggling to find a decent turret or dome camera by Dahua with a 1/1.8" sensor that is available in Australia. Do you guys have any recommendations?

Also, RTSP is not available via web browsers as the browsers cannot process it. RTSP streams need to be processed by software such as VLC etc. I need a DVR that will provide http access to the camera stream. Any suggestions?

The 5442 series and I believe @EMPIRETECANDY ships there. Reach out to Andy and check out his online store.

Hi @ubntu

Many of us faced the same issues attempting to source better cameras, and ended up purchasing with Andy.

I've had good experiences with my purchases from him, as have others and would recommend checking to see what he may have that would be suited for your needs.

Note: we have a number of vetted vendors by the ipct community ( see the vendor section ) in the USA .. iirc Andy in the main one for international ordering.

Thanks for the response - A colleague of mine has a Dahua NVR model XVR5108H-4kl and I was playing around with it the other day, we couldn't work out how to stream via HTTP. Is this unique to specific Dahua DVRs? Just want to make sure I purchase the right one

On newer and better dahua cameras like 5442 you have a third stream option... you can set it to 1080p and MJPEG

You can use any browser to open the mjpeg stream...

should be

Code:
http://ip/cgi-bin/mjpg/video.cgi?channel=1&subtype=2

these are camera settings not dvr.
xvr is only useful for coxial... they can add ip cameras but you have less to zero config options...

this is all ip world, not dvr and coaxial... coax in 2021 should only be used for good reasons

Ahh so the cameras must be IP cameras? My colleague only has COAX cameras, so I'll make sure I get IP cameras to ensure this functionality is present :)

it is model/brand specific.
many cameras has slow cpu, so they do not have third stream... first substream on most cameras is only vga and you need it maybe for something else (with h264 codec).

the screenshot is taken from 5442 ...

the cheapo cameras you posted earlier will not have these features or only in a limited way. even some "top model" hikvision cameras do not have third stream...
also on some cameras you will lose the ability of using other features when enabling third stream with higher quality...

I agree that only IP cameras should be installed at this point. If for some reason you have to use coaxial cameras, then you will have to rely on the NVR to provide HTML feeds. Not all of them do. If you use IP cameras that provide HTML feeds, or use an automation system that can display a RTSP feed, then you rely on the individual cameras to provide the feeds. This is usually much easier to integrate because you don't have to have a mechanism to change views, etc like you would with a NVR. With individual cameras, If you want to see camera 2 instead of camera 1, you simply change the HTML address too view camera 2, etc. It really can't be any more simple.

This is great advice! Thanks so much guys. So in summary go for the 5442 series of cameras, hook them up via Ethernet/IP and stream footage from the http feed that they offer.

Any recommendations for the NVR?
