- The following guide was written for (K)Ubuntu OS
- The camera has a web-based interface and it should work in any OS (Firefox browser is recommended)
Lens Adapter Ring
Check if you need the C/CS adapter ring to connect your own lenses.
When the camera is properly connected to a PC the leds on the back will go solid yellow and blinking green.
1. Standard PoE Injector
2. 12V Power Module (ONLY FOR 12V CAMERAS)
The default camera IP address is 192.168.0.9* ("ping -b 192.168.0.255" if it accidentally has some other address)
- Ensure that your PC or router/switch, the camera is connected to, has an IP address from the same subnetwork – that is 192.168.0.xxx.
- When you get to the camera's home page - the IP address can be changed from the Preferences page.
Now, in case you IP belongs to another subnetwork (for example, your IP is 192.168.1.xxx), you may not be able to access the camera - therefore, you won't be able to change its preferences. What you have to do is use Elphel's Live USB. Change your BIOS settings to be able to boot from a USB device that has Elphel's ditro installed. Once the system from the USB is running, let its program map the connected cameras and connect to them. Mind you, with the live distro the default IP address (192.168.0.9) should work. From the camera's homepage, go to System Preferences -> Network and change the IP address to 192.168.1.9 (in the example we are using). You can now reboot. Everything now will be working as expected.
Default user is:
Login: root Password: pass
Camera Index Page Menu
* It is recommended to use the Firefox browser.
- Main Applications menu items:
- Camera Control Interface
- Disk Recorder (only use this if you have an actual disk: HDD, SSD, compactflash card connected to your camera)
- Parameter Editor
- System Preferences
- File Browser / Text Editor
Open the Camera Control Interface (camvc).
Getting the first images
In the Camera Control Interface (camvc): "Shift+Click" on the button to save.
wget http://192.168.0.9:8081/bimg -O filename.jpeg
In PHP it will be just a system() or exec() call:
system("wget http://192.168.0.9:8081/bimg -O filename.jpeg");
Camera GUI(camvc) Controls
Watch/record video stream over the network
There are several ways to watch/record video streams from the camera:
1. watch: camvc
First click on an icon with a "screen" (the 3rd one from the left) and then change the display mode to "a guy on a bicycle".
This icon is only active if you have a media plugin installed in your web browser. Elphel's live USB uses "gecko-mediaplayer" together with "gnome-mplayer". Other media plugins (such as the VLC plugin) also may work. In case the "guy on a bicycle" icon is inactive, check if you have one of them installed - in case it's still not working you may have to uninstall "totem-mozilla" (this is the case for Debian Squeeze and Iceweasel).
2. watch: player GUI / command line
To watch the video stream with MPlayer or VLC open the rtsp://192.168.0.9:554. You can use either a player GUI or a command line. Here is an example command from Linux terminal window:
mplayer rtsp://192.168.0.9:554 -vo x11 -zoom
vlc rtsp://192.168.0.9:554 -V x11 --rtsp-caching=50
The default setting for rtsp-caching is 5000 milliseconds which means the stream is delayed 5 seconds which is not very handy for real-time video preview so the above commands starts VLC with it set to 50 ms
3. record: command line
mencoder rtsp://192.168.0.9:554 -ovc copy -fps <fps> -o <file_name>.mov where <fps> - approximate value of the frame frequency (this parameter is mandatory); <file_name>.mov - the name of an output file
vlc rtsp://192.168.0.9:554 -V x11 --sout file/ogg:<file_name>.mov
Command line access
In the terminal window: ssh firstname.lastname@example.org
In the terminal window: telnet 192.168.0.9
Firefox address line: http://192.168.0.9/phpshell.php
In a terminal/phpshell type reboot -f.

Accessing camera parameters
http://192.168.0.9 -> "Parameter Editor"
Navigate through the 1st table links. They cover most if not all of the camera parameters.
On-camera script "parsedit.php" - through a browser or AJAX GET call
The response is in XML form:
Note 1: It's just if the parameter value is specified it will be applied. The call can have mixed specified and unspecified parameters.
Note 2: The new value is read on the next call.
Keeping settings after power off
http://192.168.0.9 -> "Parameter Editor"
Scroll to the 2nd table.
- "Save" button
- Optionally write some comment and press "Update" to the right of it. Next time the camera will boot with these settings.
- To set the parameter group used at boot time, select it and press "Update Default" button.
