Do Lumenera's cameras work with the new Windows Vista operating system?
Yes, our existing 32-bit drivers and camera software work with the Windows Vista 32-bit releases. If you have a new or upgraded computer with Vista, simply download the LuCam or INFINITY installations from the Support -> Download centre of our website.
We anticipate having new drivers to support 64-bit versions of Windows Vista and XP completed by the end of Q2/2007.
How to activate an older INFINITY camera for INFINITY ANALYZE?
INFINITY cameras purchased prior to July 31, 2006 were not enabled for use with the INFINITY ANALYZE application. These cameras can be activated in-the-field, without the need to return them to Lumenera. A one-time upgrade license fee applies. The activation utility will be sent via e-mail once the upgrade request form has been completed and submitted to Lumenera.
Which operating systems are supported by my Lumenera camera?
All versions of Windows operating systems, except Windows NT, are supported by all Lumenera USB 2.0 cameras. We do have plans to support Linux in the future.
How much power does your camera use?
Our cameras use from 2.5 Watts up to 4 Watts of power.
Are the Lumenera cameras CE certified?
Yes. We do certify all of our enclosed cameras for the CE mark. All board level cameras are CE ready with an appropriate CE certified enclosure.
Which sensor is used on my camera?
Please contact our Support team at support@lumenera.com for more information. Please provide the camera model you are using in your email.
What are the recommended or required Windows 2000 and Windows XP Service Packs and Hotfixes?
We require Window 2000 with at least Service Pack 3 or Windows XP with Service Pack 1.
How do I know if I have the most recent version of LuCam software?
The most recent version of the LuCam software is always posted on our website. You can determine the version you are working with by opening the LuCam application's About box. This box displays the software versions for the overall LuCam software, the API, the device driver, the camera firmware and its FPGA load.
Can I pull multiple video streams from the camera?
No. This camera will only support one video stream to one application at a time. However, you can have more than one application access the camera at a time.
How do I control the exposure time?
The exposure time can be controlled through the LuCam API. The LucamSetProperty() function with the LUCAM_PROP_EXPOSURE property provides the mechanism to control the exposure of the camera when in video mode. In snapshot mode you can set the exposure parameter of the LUCAM_SNAPSHOT structure.
How do I control the frame rate after I have configured the camera?
The camera supports a parameter "frame rate" that allows the user to set the value to a rate that is below the maximum. The actual frame rate will be set to the nearest frame rate that is equal to, or below, this desired frame rate.
Can I do overlapping read out ( i.e. read out frame n while simultaneously exposing frame (n+1)?)
This feature is currently not available. Please check with your sales rep.
How can I turn off my USB 2.0 camera?
The USB 2.0 camera will work with your computer's power management scheme. The camera will turn off when your computer turns off or sleeps and turns on when the computer is awake. If you want to turn off the camera without turning off the computer or putting it to sleep you will need to unplug the USB 2.0 cable and the external power supply (if used) from the camera.

What is the maximum number of USB 2.0 cameras on a single USB 2.0 bus?
In theory, you can have up to 127 USB 2.0 devices on one USB 2.0 bus. This value includes all hubs required to connect all the other USB 2.0 devices on the bus. Assuming you wanted to connect as many cameras as possible and you assume that each hub has 4 ports, you would be able to connect, in theory, up to 94 cameras using 33 hubs. In practicality though, we do not recommend connecting more than 4 at a time as the performance of each camera will be 1/2 of its max throughput.
My laptop's USB 2.0 port doesn't supply enough power to my camera. How can I power my camera?
All Lumenera cameras can be powered externally using a power supply. The requirements for this power supply is as follows
I only have two USB 2.0 ports available on my computer. How can I connect more than 2 cameras on the same bus?
There are two options. Either you can purchase a USB 2.0 Adapter card for your computer with extra USB 2.0 ports or you can purchase a USB 2.0 hub.
Do you provide a longer USB 2.0 cable with your cameras?
The standard cable we provide is a 6' (2m) cable. We can provide a 10' (3m) cable and a 15' (5m) active cable upon request. Please contact sales@lumenera.com if you require more information on ordering these cables
My USB 2.0 camera is not recognized by the system and not listed in Device Manager. What should I do?
Follow these steps to correct any issues you may have with the detection of your camera in Windows:
Why does Windows Device Manager incorrectly list my Lumenera camera, or displays an exclamation mark beside the device?
This happens when it does not find the correct drivers for the camera or the New Hardware Wizard was terminated before completion, or with an error. Please see question 20 for details on correcting this issue.
Why is my image darker in the corners?
This issue, known as vignetting, happens when the lensing used is too small for the camera's sensor. Make sure that you use the proper lens/optics for the camera. Your camera's datasheet will state the size of the sensor used so that you can properly match your lens/optics.
Why can't I get the advertised rate of streaming images from the camera?
There are a few reasons why you cannot get the advertised frame rate.
How can I access the LuCam API DLL in Borland C++ Builder?
In order to use our LuCam API library (lucamapi.dll) in Borland C++ Builder, an import library file needs to be created for Builder. This can be accomplished with the IMPLIB utility. (IMPLIB whatever.lib lucamapi.dll) The following link describes this process in more detail, www.lumenera.com/LuCamAPILib.php . See Step 3, Case 1 for more information.
When I am debugging an application in Visual Basic and stop the debugger while the application is running, I get a error in Visual Basic and it closes down. How can I correct or avoid this issue?
This is an issue with any development environment, not just Visual Basic. The issue is that the DirectShow filters are still trying to stream to the preview window but it is no longer available. What you need to do to avoid this issue is to stop the stream and close the preview window either by closing the preview dialog box or by calling LucamDestroyDisplayWindow(), if it was created by the LuCam API.
Do you support DirectX and/or DirectShow?
Yes.
What lenses do your cameras support?
Our cameras support any C-Mount based lens. You can also order cameras with either CS-Mount or microlens mount.
How can I synchronize an external event with the exposure period of this camera in the streaming video mode as well as in the snapshot mode?
In video mode you can use the Start Of Frame (SOF) signal that is generated by the camera to synchronize a strobe. This pulse is generated at the end of the previous frame prior to exposing the next frame. In snapshot mode you can use the strobe output of the camera.
Do you have a USB 2.0 driver for Macintosh?
At this time we do not have plans to support Macintosh operating systems.
Do you have a Linux driver for your USB 2.0 cameras?
A Linux driver is now avaiable. Please consult with the support team for more details at support@lumenera.com.
