Monitoring an IP Camera using a Raspberry Pi (no internet) 

Are you sure? Working fine?

Yes, you just need to use the raspian os buster version cause omxplayer is not supported anymore on the newest one. I have this solution working in a raspberry pi 4 and in a raspberry pi zero 2 w.

Correct. Pretty much all modern hardware supports auto crossover (Auto MDI-X). Auto crossover is actually built into the gigabit ethernet standard but slower interfaces often support it too.

Great to hear!

I have a couple of videos on that: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-CuNQYKwqf7E.html Also this one: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Xr1XTl0cAAE.html When you are doing things like that, it is best to use the secondary stream at a low framerate if you don't have powerful hardware.

I’m guessing this could be used in headless mode but it would be more efficient to transfer the video stream to the remote computer directly.

@@RickmakesHi, how can we do transfer as you said?

I haven't tried two monitors. I do have a video on doing 2x2: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KhzdloBcBpo.html This page talks about how to specify which monitor you want omxplayer to use: www.raspberrypi.org/forums/viewtopic.php?t=244589 You could try expanding upon the technique in my video and try it on two monitors.

I use a lot of Amcrest cameras. I have a playlist in the description with videos on them. The Overlay file system allows you to cut power to the Pi without shutting down. Normally this could corrupt the SD card. The potential downside is that the system is read only. You have to turn Overlay FS off to make changes and the re-enable it. It isn’t really needed if you can shutdown the Pi before unplugging it.

@@Rickmakes I understand! Thank you very much for your kind answer! And thanks again for the video! :)

This isn't connected to the internet so it is completely isolated.

any update? I can't find any store to buy PI 4 so I wonder if I can do it as well with 3B+

poe injector cannot reduce the number of cables. one cable can connect them all unless you exceed the data size you can carry with that cable. you just need a switch for that. you may also use a POE switch(not injector). at the end, they all have to be in the same network. that matters only.

You wouldn't want to connect the Raspberry Pi to a network with the configuration I used in the video since it is running a DHCP server that could conflict with an existing DHCP server. You can connect the Raspberry Pi and camera to an existing network and leave out the DHCP and dnsmasq configurations. You would need to look on your network's DHCP server to figure out the IP address of the camera and then you can connect the Raspberry Pi to it.

Yes. You could set up the Pi as an access point. Then I would connect a computer to the Pi using wifi (to configure the camera) and then connect the camera to the Pi using wifi.

@@Rickmakes have you and oder on how to communicate then?

If you are able to use an rtsp stream with opencv, then I would guess it would work.

Don't use bullseye as omxplayer is being deprecated and resources are directed at improving vlc. Go for buster in this case.

This should work with the small Raspberry Pi screens. You could also get this working with wireless security cameras and a wifi Pi but that is more involved.

@@Rickmakes yeah for sure. I like the no internet concept. It can boot camera view right on startup?

@@ShyneflowLC It pulls the camera up after the normal boot process. This can take a minute or so. There are probably ways to optimize the boot process that would speed it up but I haven't gotten into that.

@@Rickmakes that would work for me

Do you have the camera's output set to 1080p or 720p h.264?

Are you wanting to view the camera remotely? I have a video on that here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-r80dcfzClD4.html If you are wanting something else, let me know exactly what you are wanting to do and I can see if I can help.

I think I used 32 for this but can't remember exactly.

I'm not sure if it is still available. Most of the other Amcrest cameras should work in a similar fashion.

Wondering the same.

The latest version of Raspberry Pi OS doesn't work with omxplayer. I would try using the "Buster" version as I think it still includes omxplayer.

Did you previously have the camera configured to use a static IP? You might try resetting the camera as the default mode should be to retrieve an IP address via DHCP. The other thing to check is that the DHCP service is running on the Pi.

i've solved the problem now i'm able to get the live feed but now when i run it from vlc i'm getting an error "failed to open xsplitter:mmal_vout module" plus i'm unable to run the video on startup. i have followed your steps throughout but still when i run sudo systemctl start camera there is no error but its not showing any results.

To connect multiple cameras, you would want to use an ethernet switch.

If you just want to view a webcam on a Raspberry Pi, I have a video for that: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MA6x2jmURh4.html A USB webcam and microscope present the same to a Raspberry Pi. If you want to transfer the webcam over a network, that is a more complicated setup. I don't think I have a video on that.

Do you mean steam audio from the IP camera or something else? This should play audio if the camera supports it.

@@Rickmakes I'm talking about using a PiZero and a USB mic on it. Right now I have 4 PiZero W that I get to by RTSP and can get each to Display on VLC Player or as I have it now I am using Shinobi (NVR) so I am saving the videos on a Pi 4 that runs the NVR. I can never find anyone who has a project that can save the audio with the video. On Windows this is a no brainer. I don't know if it's an issue with Linux based systems of software but Windows has always be so easy. I use the Pi Cameras hooked up to the Pi Zero's. Thanks for responding. Most people hardly ever do.

@@Rickmakes Really? After a year, no replies yet?

The default user name and password is pi and raspberry respectively.

@@Rickmakes error: ""E: Package 'omxplayer' has no installation candidate"" occur, when install omxplayer. Please help me fix it. Thank you
