Does ZM work on a Raspberry Pi 3?

Post by Microchip » Mon Apr 27, 2020 4:05 pm

Hello!
Excuse me for my English.

I'm testing ZoneMinder and other similar software to figure out which one to use.
Each has its own pros and cons and Zoneminder seems to me to be one of the best.
However, he has a very limiting problem that would lead me to exclude it, unless I'm wrong, so I'm trying to understand.

I installed ZoneMinder on a Raspberry 3, currently with only one cam.

Without recording anything, after some time of activity:
1) the cam goes offline
2) slows down excessively or even freezes the raspberry
3) obviously if I make the registration it becomes very slow

The software is good, but on raspberry (where I need to put it) it seems unusable.

Did I do something wrong or does it work this way?

Thanks!

Lower FPS and / or lower resolution of camera

I disabled log.
I already set Capture Resolution (pixels) to 640*480

But where should I set the FPS?
In General I set nothing:

Resolution and FPS are set on camera webpage.

Don't set Max FPS in Zoneminder (exception is local cameras - i.e. webcams).

Depends on the camera. Usually, 640x480 should be no problem for a RPi3 if its h264 pass-through. Capturing from analog camera might be a different number.
Also, try to avoid using the RPi as client directly (desktop browser/event viewing). This is a very powerful process (JPEG streaming presentation) and should be better outsourced to another system (desktop/mobile).

I have a raspberry pi 3 with a 7 '' touch display: the intent was to also use it as a client, otherwise I have not solved anything.
I had thought of using it only as a client if anything, but ZM does not exist for Windows (like a PC always on at house) and certainly I do not put a virtual machine on it.

I believe ZM may have been the best choice, but not for a solution with Raspberry.

I want to confirm that not using raspberry as a client works better.
It doesn't solve my problem, but it's a step forward.

Just so we don't confuse anyone, by not using ZM as a client, I believe you two are referring to running X on an RPI.

There is another way of using ZM as a client, which entails watching a video stream running by a ZM server where the RPI only connects into the ZM server but is not the server. That should still work well for an RPI. Similar to this post: https://zoneminder.blogspot.com/p/odroid where an odroid is used.

I make a summary (excuse for my English):
I have installed ZM on a Raspberry Pi 3 (Raspbian).
Then I visualize on its screen, through Chromium, the video camera (at the moment it is one, but they will become two).
However, even without active recordings, after a while the camera is offline or the Raspberry Pi crashes.

Since I keep the browser closed (I don't see the camera), but I only see the X desktop empty, I have not had any problems.
But obviously I can't use that "hanging on the wall" system at home to see the two cameras as I would have liked.
In addition to the fact, that so the touch display would be wasted.

Other ZM competitor software instead works without problems simultaneously with both the client and the server on the same Raspberry, but ZM seemed to me the best in the various tests that I am doing.
I'm trying to decide whether to keep it and find a solution (if there is one) or to change software. I'm still in the testing phase.

please try those FPS settings at 5 or 6
