Hardware :: Can't Seem To View Both Cameras At The Same Time?
Aug 29, 2009
I have a small issue that I would <3 to get worked out . Here is the skinny of it. I have a laptop running Ubuntu 9.04. It has 3 USB ports. I have 2 Logitec Quickcam 4000's. I am using zoneminder for viewing the cameras. The issue that I am running into is as follows. I can not seem to view both cameras at the same time. If I unplug one of the cameras the other will work fine and vice versa so I know the cameras work.Here is the output of lsusb without the cameras
Code:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

I looked around on the web using all the google-fu that I have available to me and I just cant seem to find what I am looking for. I was even going to make my first attempt at compiling the driver but I don't really know where to look for info regarding bandwidth limitations...nor do I really know where to place the driver source, and what to do after I make make install .
I have a DVR with a Linux Operating System, I have a problem viewing my cameras from another internet server that is not the Internet Server where my DVR is. For example I have spoken with my internet provider and checked DNS, Gateways, ports and all the numbers that I configue my DVR, which has a Linux Operating System, and even made the updates, but still I cannot view my cameras from outside this same internet provider.
Is it possible to install Snavtclient, as i don't have much idea but i heard that i can view cameras online for AVTECH DVR once it is installed, i tried to download and install it through terminal but got this error.

I recently made the switch from windows and mac system to fedora 13 64 bit kde, which has been a challenging 6 months, not having a IT background. Anyway, overall now that I am getting the hang of it I really like fedora 13 kde, nice job guys. I have one final obstacle remaining that I have not been able to figure out. I have the necessary rpms for video and sound. I am able to successfully copy video from DVD's and play them from hard drive without issue using VLC. However, when I try to import avi files from my camera's sd memory card, the videos always end up "corrupted" and when repaired do not play sound. Again, I can play AVI's from dvd's fine. Interestingly, I can take the same files from my fedora box and copy them onto a usb stick and transfer them into my mac and they play fine.
I suspect there is a codec issue possibly with VLC, but not sure. I also tried on the default player, but cannot remember the name of that right now and my wife is presently watching her Mary Kay dvd on it as it is hooked up to our TV . My video codec knowledge is pretty basic. Can someone point me in the right direction of what the problem might actually be, another post, something?
Does anybody know of any digital cameras that can be controlled via Debian? I'm not speaking of a webcam but a digital camera, and I'd like to be able to send commands to the camera via usb; perhaps by means of a bash script that would take snapshots every x seconds for a total duration of y seconds.
I am very new in Linux in general. I installed ubuntu 10.04 in a server that I want to be a CCTV server and record video from my survilience cameras. It was very hard to install the driver (it's a generic card from DX with 4 inputs) but finally it worked.in Xawtv I see the camera, but I need a good software to capture it. I tried to install zoneminder but it's too difficult to me as a newbie in linux. I installed wxCam and it worked, but it's only for one camera, I have two. I need a software that can capture from both cameras in the same time and not so difficult to install like zoneminder.I want something that will just work, just install and run.
I've written a simple web page and I want it to display live stream from one of my IP cameras. I admit I've never been interested in HTML ... How should I go about this? I can see the stream in browser using following link [URL]
How to connect HDMI camera to Linux? I have tried a few cameras such as the Bullet HD. I was never able to make it work in my CentOS, Fedora, I returned their product finally, it was a nightmare. Therefore instead of risking for next failure I am looking for a definitive answer on this, so that no driver issues arise under Linux and finally allow me not to use Windows or Mac anymore. Has anyone ever had success with making a very very good quality camera work in Linux, such as for example this one? Which HD cameras are there for Linux? There should be no driver issues and they should also allow me to perform pan/tilt/zoom actions using USB, Firewire or the S-Video interface.
Simple. UUID is apparently limited to a single UUID to be defined. Example UUID="DEB0-0001","3338-3164" separated with a comma is not working.
What could be the linux alternatives for pluging several UUID disks? How to bypass when there is a CF card and a reader box, since blkid gives no UUID ?
I have been setting up multiple security system in the area and was wondering what was the easiest way is to get the camera information that one would need in setting up survellance systems like zoneminder. I use xawtv for testing and
PHP Code: zmu -d <device_path> -q -v
But how can I get specific information about NTSC/PAL cameras or IP cameras. In other words is there a specific tool for that purpose? I can see my video cameras fine using xawtv -c /dev/video but can I look at those log files to see what setting it used for the cameras
<<mod edit: no longer relevant after moving post to new thread>> I'm currently trying to find which web cameras RHEL desktop 5.x supports. Does anybody have a list? (I was searching through hardware.redhat.com, but it is mainly oriented to server and workstation elements)
I'm running ubuntu 10.04 and suddenly when plugging my cameras or usb sticks, they don't automount anymore, but they did before. What changed is last days I tried to build and install nautilus-sendto manually from source, and it required dependencies including GTK+3.0 (unstable), I don't know what happened exactly or if my system is broken, because some of this packages built and installed fine and others failed. If someone wants to help with that to get my installation to its original state it would be awesome.I could mount my usb stick installing usbmount, it worked, but I didn't need this before.What I want now is to mount my cameras: here is the output for:
I've a question regarding two camera images. Suppose I've detected 2d window coordinate of 8 markers of an object in a scene in one camera and detected window coordinates of 10 markers of the same object on another camera.
I've detected the marker. It was easy. Now how do i know which window coordinates on two cameras are the coordinates of same marker? I mean there are markers captured on both cameras and some of them are representing the same marker in both cameras. I just like to know which ones are same on both cameras. Is it possible to find that out using opencv?
I have been working in macromedia dreamviewer for editing html and php files, Just now I moved to linux system by installing xampp , my question is that I need a best html and php editor that supports both the design view and code view as like in dreamviewer.
I wanted some input on chronic problems with Ubuntu:
1. Why does wireless almost never work right on Ubuntu?
2. Why, when Ubuntu just decides to turn off my wireless card, can I not just turn it back on?
3. Why do tar balls almost never unpack right?
4. Why are printer drivers so buggy?
5. Why do my MP3 players and digital cameras not work with Ubuntu?
I spent 3 hours last night trying to unpack a tar.bz2 file so I can run my Ralink network card. It worked fine until my son unplugged my computer. Now my card is disconnected and it will not reconnect. When I check forums no one has a simple answer for something as simple as turning a network card back on. On my Apple, it's simple: click my wireless icon and hit "on." tell me an easy way to just turn my wireless card back on, it would renew my faith a little in Linux.
When booting Fedora 11, my system hangs for a very long time on starting udev. Sometimes I get an I/O error. However, my hardware is fine. I do eventually get in to the system.
It takes me a while to log in the splash screen just sits there for ages before i get to the desktop. Never used to be this slow and I'm not sure why. Firstly, I'm running Ubuntu 11.04, standard DE. I do have conky starting up in a script but it has the & at the end of the line so I didn't think this would cause it (or is there some special case for log in time on how & is treated?). However as a test I will comment out the line in the script and see if it is the cause.
However just for general knowledge and in case that isn't the problem, how does one go seeing what is happening during the time from when one log's in and the desktop is displayed? Is there some kind of log that shows the date/time that can be enabled or is there a debug mode that can be enabled somehow via special keys or maybe from grub?
I am using Debian linux. I have 100 timers running. If a timer expired which will generate a signal and it was mapped to a same function handler. All the timers are mapped to one function handler. The problem is if the timer expires one at a time, the function handler called at a time. But if the 2 timers expires at a time, the function handler is called one time only instead 2 times. Is it possible to invoke the function handler as many times based on timer expirary happens simultaneoulsy?
I've got fedora 11 set up to use network time protocol to sync my laptop's date & time when I'm on-line. The question is simple really, I've added a local universality's time server (what is public) and it's live. but it's added to the end of the default time servers what come with fedora. How do I get fedora to just use the local time server, is it a case of removing the default time servers for fedora, but there is a box what says advanced options which are. sync system clock before starting service ???? & use Local time source (( is that the same as the local ntp server that I've got set up ))Hope some body can help me with the network time protocol part of Date/Time settings.
I have several file servers in our offices and I am relatively new to Ubuntu / Linux. I get notices that there are updates for the server software from time to time. Is it typical to update everything when available or should I follow "If it ain't broke, don't fix it..." mentality?I would hate for everything to be working fine and then have an update throw me a curve.
I am running my Ubuntu 32 bit server on top of Windows 7 64 bit with VirualBox. It's a 2 core Atom. It's been working good for about half a year. But the last about 6 weeks the system time only in Ubuntu is going slow. About -8 per 24 hours! I can only guess because I have more things running in my Windows 7 and Ubuntu.
I can set it right by coping the hareware time to system time with this command:
Code: hwclock --hctosys
I want to run a crontab to have that command run every minute. But it don't seem to run.
Since the upgrade from Lenny to Squeeze on my Notebook Toshiba Satellite Pro U200 with Intel Pro/Wireless 3945 ABG I have wireless connection problems.The connection breaks time to time and sometimes cannot connect automaticaly after restart. BTW I didn't change anything on the wireless or network configurations on the notebook and on the wiereless router.
In the right upper corner of your screen,you can see if you have a network connection or not.Most of the time I do not have one according to Networkmanager (?).So I have to enable my wired connection manually.I already tried a lot to change my settings so I would have a network connection at boot,but it doesn't seem to work....Firefox is in Offline modus when I logon..
For like windows you can resore your os to a state of peace kind of. If you messed up your vital files you could go back in time and restore you computer to a selected time. I was wondering if you could do that for ubuntu
I have a Insprion 14R (N4010) and when I hibernate it will usually restore without a problem, but maybe 15% of the time it will reboot while loading. I would like to figure why, since I'd rather not lose anything... My swap space is 5.9GB, I have 4GB RAM (video uses 1gb, so I have 3gb usable)
I'm looking for a program that will digitally display the time in three different cities - all showing at once. I don't care if it is a panel applet or stand-alone. I'm using Suse 11.3 and Gnome.
I have a linux (Slackware) machine and the time/date is like, June 23rd 2003, 10:00am (It's 11 here) and I am not able to set the time to have it correct. I change the timezome to Montreal but the time is still wrong.
Is there a way to force it to sync with my domain controler or even another online NTP server?
