Hi, in various nodes, we need to config the path for where the image must be written/retrieved from. Should these folders be child folders of node red? And must permissions be applied?
I usually put it under my home folder. In my case node-red is running under the same user, for example pi on the raspberry pi. Therefore it has access to read and write under /home/pi. But if you want to put it in a completely different folder, the node-red user should have access to it.
In your second example, you have the image saved to a file. Is there a way to overlay data, say from a temperature sensor, as text on the image so the text is saved as part of the image? Great info on using node red. Thanks for that!
Uh, there is a very good question. I played around with a node which renders a chart on a "canvas" that exports it into an image. I think using a similar approach it could be done, but I don't know how and I don't know if a similar node exists.
Oh yes, I forgot. Onvif nodes are not yet in the palette manager. You can download it from here and also there are instructions how you can install it: github.com/bartbutenaers/node-red-contrib-onvif-nodes
Well, it depends. This flow works on the local network, the cameras must be visible to Node-Red over the network. If the different wifi is the 2.4 and 5 GHz wifi on the same router, it is probably not an issue. If they are on different access points, you need to configure them to be visible (NAT, port forwarding, or DMZ, etc).
Hi, the last week my RLC-410W is connected directly to the router by lan and no mre with wifi ... Now, in my dashboard I have one image from the cam that I update every 3 minutes, well is possible to have the continued live image from the cam since now it's on lan?
Live stream was never important for me, so I did not explore this option. Google how you can embed VLC played in a webpage. VLC can play the RTSP stream from RLC cameras.
Trying to get this work using HAOS in a VM with an 811A. The docs say HAOS has ffmpeg. I've changed the save path to \config\myfolder. My ffmeg cmd is: ffmpeg -rtsp_transport tcp -i rtsp://xxx:xxxx@xxxxx:xxxx/h264Preview_01_sub -r 10 -t 10 -vcodec copy -acodec copy -y I get an error 127 from the exec node. If I put the rtsp address into VLC I can see the camera feed and I'm sure HA can reach the camera as I'm using the Reolink integration. Any ideas? Thanks,
Hello, I have an REOlink 4K camera but I don' t have bandwidth to be able to share the stream. I am wondering about using the link you are demonstrating if it will work with a public IP. Do you think I can make a button on my website for users to click that will open a new browser window and capture the live jpeg image in the browser? That way I don't have to ftp the current photo and change it every 5 minutes for them to see the view. I also don't need to store any images since they generate it themselves. Do you have another way you recommend to share images if this wouldn't work?
Hi, I need your help .... I change my Reolink from RLC-410 to RLC-510 .... I have not problem with the image on dashboard, but I have problem with motion detection. The instruction "Set - msg.action - start (and stop)" in node red return this error "Action start is not supported". So the cam is CONNECTED but not LISTENING. Can you help me to fix this error?
Hey thanks for the nice description in the video. This gave me some good ideas. Unfortunately my Node-Red crashes, if i start listening on events and a event is triggered.
I suggest to open a discussion on Node Red discourse. BartButenaers is the author of these nodes and he is fairly active in the forum. So just mention him in the topic and he will come back to you in a few days.
Hi, thanks to you, now I have my RLC-410W in dashboard! But if a movement is detected I don't have one message, but same message, so my amazon echo don't speak "allarm!" but "allarm!", "allarm!", "allarm!", "allarm!", "allarm!" .... Can you help me?
An utterly useful video again - keep them coming!
Thank you very much. Very helpful.
does this work with the Reolink video doorbell POE?
I did not test the doorbell, but: so far this has worked with all wired cameras, so I think it should work with the POE version.
Hi, could you give me some hints to the "image preview" node. I can not find it. Thanks in advance, Christian
Ok :-) Got it. Perhaps i should look the whole video before i ask a question, and don't experiment with the flow directly.
@@helikrysly :) it is a long video, easy to miss.

Hello Mr Varga, where can i get the library for the nodes , i cant find the palette for onvif .THX in advance

what happens if camera is not connected to the same wifi than the computer or device where we are running Node-Red?
Well, it depends. This flow works on the local network, the cameras must be visible to Node-Red over the network.

can i use this solution for industriel camera ( svs vistek) ?
@nourtrabelsi6271 The url that return an image is not very common feature. But if the camera supports onvif, the rest should work.

I don't think it works on public IP. Just like with battery operated cameras you only have the Reolink app to work with nothing else.
@@csongorvarga Thanks. It seemed to good to be true.

I am about to receive 510WA very soon. I will try to see how that behaves. To be honest I did not use onvif on these camera since I made this video.

Hi Csongor, I do not have access to the node-red flow link. Is the link still working?
I just tried it. Works or me. Could it be that you are trying this from work. Some companies block Google Drive access.

Yes, if you see my flow, I added a delay node after the switch node and limited the messages to 1 per every 15 minutes. There is no other way.
