Detecting objects using ESP32 CAM and NODE RED

Nice layout!! But with stills??

EDIT (I think the media node can only play video from file, not directly from a stream)

Yes multi-client streaming perfect, I took the rtos version, you see that camera view in the largest frame above, garden view through the window

What did you do to get the streaming working??

Here's my experimental layout if you want to try it out - stills only and no functionality apart from 'Reset'.
I'll swap-over to using ui-template widgets later.

Hi Walter - to fix the layout issue, just increase the width to 900px in the 'template' node.
Screen Shot 06-19-21 at 07.41 AM

Walter - is this the version you used (that you have had success with) ??
Screen Shot 06-19-21 at 07.46 AM
I'll try it ASAP and see if it works for me.

EDIT:
Yep tried that version and it does work across multiple windows - but very slowly.
Only got one camera working, due to a slight technical problem - see below.

EDIT:
Just had a major catastrophe.......... micro USB socket has fallen off of daughter board.
That will explain why the camera kept stop working the other day. Looking at it looks like a dry joint.

Yes, I now have success with all versions, all are also very fast but I have the ESP32-EYE, don't know if that makes a difference (I bought them 2 years ago, then at 17 EUR each)
What I did, I re-installed Arduino IDE and updated the board list with board manager. After that, it worked without problems. When I then tried to update to the latest drivers as described earlier, it did not compile, complaining about soc/* files missing. But reverting back, everything now works perfect, even changed the resolution to get faster updates

Ouch, bad luck, guess that could be the reason for bad performance etc

Thanks, will try that!!

Almost there, but still cam one and two are not in the left column, I have problems with the layout editor I guess, do you know??

Thanks for the update. I'll try doing a fresh install on another PC.
My ESP32-CAM has a micro-SD card slot, but aprat from that looks very similar to the ESP-EYE.

That's an easy one - just need to move things around in the Layout Editor.
Screen Shot 06-19-21 at 09.32 AM

Thanks, got it now!!! All working well!

Hiss, boo - dead jealous. Only one camera working here, other one sitting on my desk in pieces.
Next task is to contact Amazon for a replacement or a refund.

EDIT: My personal preference is to use the Dark Theme for the dashboard.
Easier to read for my tired old eyes!!
But again it's down to personal taste.

EDIT: The flow I posted above pre-populates the drop-down menus so is easier to manage.
I need to put a fixed IP address in the sketch and multi-wifi details so it picks the strongest WiFi signal.

Update to the Home Surveillance flow and dashboard layout using 'template' widgets.

Sorry - only got a single camera operational and functionality is restricted to just 'Reset' for now.

Guys, I tried this project and It worked very well:

Enjoy!

Working so good!!! Impressive

I really like your dashboard layout - so neat and tidy and ergomomically friendly (ha, ha, ha).

Error: read ECONNRESET

Guys do you know what cause this problem ? and how I can fix it ?

So if I understood correctly: the esp32-cam cards stream the video in mjpeg on the network on an http address, and you connect to it to read it on the NR dashboard, which runs on an RPI?
I am trying to make a comparison between esp32-cam VS RTSP camera .
For example: with my RTSP cameras they consume 40KB/s at 7fps with 1 to 2% processor overload. How much for an esp32-cam?

It is a connection error... a little Googleing should show it seems to refer to a TCP disconnection made at the receiving end of a network link you are trying to make.

I ran into that error (and others) quite a bit yesterday while trying to find properly working URL's for my various cameras, while working with my own version of this topic.

Exactly what caused the error depends on what network connections you are trying. You should be able to track that back to the "problem" node via debug

And on that note... thanks to this and a few other topics...

Currently showing the HKV camera clip

The real tricky one was the Amcrest as it is an RTSP stream, and had to be converted to a JPG image before it would run the detection.

I have no idea how to measure that. From the esp32-cam is just a mjpeg stream via http as you say. The cpu load is not measurable, cant see any change if streaming to dashboard is on or off
When I stream a playlist like the red-bull it is just adding a fraction on the cpu load, almost nothing
I have no rtsp so cannot compare

do you program your ESP32 CAM to stream or to take pictures each time you refresh the page ?
I try to apply all these codes in node red but I always find errors :
Error: ENOENT: no such file or directory, open 'Error: ESOCKETTIMEDOUT : http://10.10.0.32/capture !!
( I program my ESP32 CAM to do a stream ) I don't konw if this is the problem ???
