So the question remains. How can multiple USB cameras be installed?

viewtopic.php?f=38&t=28151&p=110151#p110151

No one has seen this problem? I've found it all over the Internet but no answers that seem to work. There seems to be some sort of memory or other conflict when trying to use more than one USB camera. I would like to solve this in order to allow multiple USB cams. Does anyone have anything to offer ...

So, are we supposed to report this or start a new post asking who/how many others are seeing this problem? Obviously, I'm not alone which means others might think it's something they are doing wrong.

@mikb I've looked at the processes when this happens and don't see anything unusual. zmd seems to be running but the GUI is dead, cannot reach it anymore. In those cases, I've tried restarting the service but that only worked once, never again. The only way to get things back is to fully reboot the ...

Please, let me know how I can help. I can easily get it to crash simply my playing with settings. In some cases, the only way to get zm back is to fully reboot the server since restarting the service doesn't do it.

I understand. I'm not a coder but I am the head of a software project and the one thing we do not ever stand for is ANY reason for something to crash. No matter what you do to it, it should give you an error, complain, call you names, not serve you breakfast for a month but never crash. >Do experime...

It's a fresh install and only using 20GB of a 1TB drive so I think what you're talking about is related to something else. >It's likely you've got a memory corruption due to data being delivered from the camera not being the expected size and shape, >exceeding a storage allocation somewhere, and tha...

Yes, I have some of those also but need a way to add analog cameras using USB. Mainly, it is to see if it can be done. The only four channel I have is a GXV3504 Grandstream but I'd like to see what could be used via one single USB port. I've tried connecting multiple local USB cams but that never wo...

I've been looking for a way to connect analog cameras into my system which is a mini PC with no PCI slots. Therefore, I need something that can connect via USB. I've come across those cheap EasyCap devices but have read that they do only 1FPS which is useless. Wondering if others have had to deal wi...

Hi, I like how you broke things down and how you 'fixed' the image :). How did you do that? I failed the post the resolution since I had tried a number of variations. At the time of the image, the camera was set to 1600x900 and so was ZM. However, now that I'm playing with it again, here is what I'v...

Without changing any settings, the night before, the output was fine. This morning, the image looks like this. 2019-03-16_085954.png I rebooted the server and still the same output. The camera is a very basic IP camera, reached by going to http://192.168.12.241:8080/?action=stream on a browser. Usin...

I've been trying to get a Logitech, Inc. QuickCam Orbit/Sphere AF working with ZM 1.32 (Ubuntu server 18.04) but keep seeing a problem. Looking around on the net, a lot, finds me a lot of old posts about problems relating to this error but nothing I've read has worked. A suggestion I read was to ins...

I'll have to read the wiki to figure out what you mean but it's more than I had .

Thanks very much

I have a driveway that need modect function but no matter what I do, shadows from tree branches moving in the wind keep setting off the video recording. I'm pretty sure I know the answer to my question (smile) but I thought I'd ask anyhow in case others have experienced this. First, when setting the...

I am searching and having trouble finding Linux based PTZ cameras. Specifically, I'm looking for one or more makes/models of consumer grade PTZ cameras between $40 and $100 that have fairly decent resolution and which run a Linux OS that I could access. I cannot use wireless cameras so am looking fo...
