• Connection to CVS GigE camera via a network switch

  It is a fundamental and very simple question!

  I intend to connect two GigE cameras to NI CVS-1458RT for an application of Imaging. When I tested the configuration in MAX, I realized that I can connect the cameras directly to the PoE ports, or alternatively, connect the cameras directly to the network switch and in both cases, connect the CVS to my network via its ethernet port. I was wondering if there is a benefit by connecting directly the VCA cameras, if I do not anticipate supply their Poe or if my switch has PoE Betacam.

  Thank you

  Usually, you always want your cameras on dedicated lines, or at least only sharing bandwidth with other devices. The mechanism of transport used by GigE Vision isn't really sharing good bandwidth with other devices. If you only share the bandwidth on a link given with other devices, you can throttle each take only a percentage of the total bandwidth. If you have devices without camera on the link, they don't usually have a mechanism to control the gap inter-frame limitation insofar as GigE vision made which would be necessary for properly sharing the bandwidth without remove the packages of bandwidth.

  If you end up sharing one of the ports for the operation and configuration of the CVS on the network, you will be at the risk of losing image data packets whenever the rest of the traffic is sent. Although there are mechanisms in place to return data, these add latency and jitter to your purchase.

• External triggering of GigE camera

  Hi, I'm planning on using the camera triggers the entry to start capturing images but I'm not sure what I need to do in my c# application when a trigger has launched.

  -If the trigger is coming from the PLC, should I also send a trigger signal to the PC and keep the active trigger signal until the PC is the acquisition of the image?

  -Do I still need use the snap or enter functions in imaqdx to get the picture?

  -If the camera is connected directly to the external NETWORK card triggering she still great benefits? The camera in less than 5 meters from the PC.

  Thank you

  Hi riscoh,

  When you work with a GigE camera you are not anything on the computer triggering its self, only the camera.  When it is configured to trigger it will sit and wait for a trigger.  When he received the signal it will take an acquisition and send the information to the computer.  When you set up your support on the computer it is searched for images and brings them into the computer as they become available.  The example I'm pointing you will show you how to set up the camera by a trigger program.  It looks like it may be available only in Visual C.  As far as the documents relate to article after the release with a GigE camera Developer area described briefly.  Acquisition of cameras GigE Vision with Vision Acquisition Software-part II

• How to identify a GigE camera by IP address

  I have a system with 8 Basler Ace GigE cameras, all on static IP addresses on the same subnet.  I would like to be able to exchange any device with a new one that is configured to the same IP and my LabView RT running on an Exchange virtual server program automatically starts using the new camera.  The LabVIEW program already sets the settings in the camera, if I don't want the user to have to use MAX for any configuration of the camera.  I want to just the user to use the Basler IP configuration tool and the tool of Basler to focus the camera, then having my program discover the camera by its IP address.

  However, I have not found an IMAQdx tool that allows me to distinguish the cameras by its IP address.  The discovering Ethernet cameras VI has an address entry, but it is only a mask and cannot me narrowly find just a single camera on an IP address.  I have not found any camera property or an attribute that returns the IP address.

  So, if I have a bunch of cameras and want to identify who is who, by his IP address, how can I do?

  Hi Ken,

  The main identifier imaqdx uses to track/locate cameras is serial number, which is identical to its MAC address for GigE Vision cameras in IMAQdx. Unfortunately us don't really use IP address as any kind of ID to connect with a specific camera, because we assume that the IP address can be dynamic and flexible (makes it spec GigE Vision DHCP and link-local addressing a requirement standard and everything is designed to allow these cases to work well).

  That said, there is an attribute called 'CameraInformation::IPAddress' that you can query to see the IP address of the camera. The only downside is we do not currently provide this information via the Enumerate mechanism - you first need to query this property of the device. Your application might first browse the cameras and do a mapping of serial to IP addresses?

  Hope this helps,

• VB6 with GigE cameras?

  I use Vision Devlopment Module 8.5 with VB6.   I wrote a lot of code using activeX controls for cameras, firewire 1394.   Are there for GigE cameras VB6 activeX controls?  If so, can you put link here for examples.  Thank you

  Hi Dan,.

  IMAQdx documentation indicates that it has supported inherited from MSVB6. Your device should work with these examples as long as it meets the standards GigE or correct DCAM to work with IMAQdx, because it's always using our IMAQdx drivers.

  I'm not sure the support ActiveX specifically for GigE cameras, but once that you have connected to your camera with IMAQdx in VB6, I don't see why you shouldn't be able to use the functions you used before. I suggest that you try to change your existing code to connect you with your GigE camera and test the functionality of your ActiveX code.

  Thank you

• The value FPS using NOR-IMAQ with a GigE camera programmatically?

  Hi all

  I'm (slowly) learning how LabVIEW plays well with the cameras, GigE, that I just bought.

  At this point, I'm trying to understand how to programmatically set the value of fps for the camera.  I have been using the examples NOR-IMAQdx to control the cameras so far, but I am open to trying anything.  Someone at - it a good example of how I can change the frame rate "on the fly?

  My next task will be to find a way to change the size of the image on the screen programmatically, so if anyone has any ideas for me on this path there, I'd be pleased them too well.

  Thank you very much

  FB

  I thought about it:

  1. use the vi IMAQdx open camera to open the camera

  2 use the "List attributes" in the palette of NOR-IMAQdx to see all available attributes

  3 using the step 2, above, I could find the attribute, the attribute "AcquisitionFrameRateAbs".

  4. create a node in the output of the open unit VI property, choose 'Attributes of the camera,' select "Attribute Active."

  5. set the property node "change all to write."

  6. connect a constant string of 'AcquisitionFrameRateAbs' attributeinto the property node value

  7. create another node in property 'Attributes of the camera', this time by selecting 'Value' and affecting the type DBL

  8. change all to write

  9 create a digital control for cadence

  10. connect the digital control to the property node 'ValueDBL '.

  Presto!  You are finished.

• Camera cannot connect NI Max

  Hello

  I have a camera Flir A6251sc I am tying to connect in my VI using IMAQdx (it's a Vision GigE camera).  I can make it work with the Flir software, but when I try to connect with the NOT-MAX I get "error 0xBFF69011 cannot GET attribute."

  I ran the validator of the camera and got the attached files.  As the camera work with their software, Flir has proposed that the problem is probably with the NOT-MAX himself.

  Does anyone have any suggestions?

  Thank you.

  
  

• FaceTime Camera: the green light next to the camera makes a slow blink, and there is no picture

  MacBook (retina, 12 inch, early 2015) El Capitan 10.11.5 now ongoing enforcement.

  Whenever I try to access the camera FaceTime (FaceTime, Photo Booth Apps) the green light next to the camera made a slow blink, and there is no picture.

  The system report > camera > model ID: Apple camera VendorID_0x106B ProductID_0x1570

  The numbers of the vendor and the product are correct?

  The camera worked for 6 months passed and I used FaceTime several times without problem.  Several users are affected.

  None of the recent changes to the system.

  Since the problem began, I have:

  (1) installed Skype to see if one application other than an Apple app had a camera problem. Skype has no camera or.

  (2) improved 10.10.4 to El Capitan Yosemite.  Hoping that the upgrade would reload the application Face Time.   No change in symptoms

  (3) reinstalled the El Capitan using the OS X Internet recovery.  I have not used the time Machine.

  (Note for everyone, it was simple and painless and does not need to reinstall applications.)  I want to reinstall MS OS was too simple)

  (4) several other threads suggested to reset NVRAM and SMC memory, even if they do not seem to be associated with the prob. who - without success here tried either

  Any advice to determine whether it is hardware or software?  Still dig while you wait for a response.

  Note: This problem is not resolved

• GigE camera - image grab bars

  Hello world

  I use or acquisition of vision to capture images of a GigE camera.

  I get images just as I trigger the camera - rates so so good.

  All other photos shows a few black bars.

  Anyone have any idea what it could be?

  It is not the hardware, the camera works perfectly with the shape of the manufacturer's software development kit.

  Thanks for any help

  Looks like an incomplete picture, this could be caused by the missing packets.  To prevent missing packets when the acquisition, you can do two main things: the size of the packets configured on the camera may not exceed what the network card can manage and ensure that the bandwidth of the output of the camera image data do not saturate interface band bandwidth.  I would reduce the packet size of camera for 1500 initially to determine if the size of the package is the cause of the problem.  You can throttle how much data that the camera can send by manipulating the interpacket delay, some manufacturers have a very handy feature called StreamBytesPerSecond.  According to what mechanism, you can use, increase interpacket delay or reduce StreamBytesPerSecond.

• Updated Windows 10 anniversary - camera stay connected - Powershot SX530HS

  Microsoft, in their wisdom, has broken the link with my camera and their most recent, like big update.  "It allows to work."

  When I connect my camera to my PC, the device says it's connected, and my computer starts the camera window.

  BUT by the time camera Windows finishes loading, the camera is already disconnected and closing the window of the camera because the camera is disconnected.  The camera turns on, it just disconnects.

  I can't remove my PC camera device because it does not appear until it is connected.  And even then, it disconnects after about 30 seconds.

  Any ideas?

  Thank you...

  If anyone has this problem - mine, just start the configuration of Wi - Fi in the Canon Utilities.

  In doing so, turned on my camera to connect to my PC and I managed to upload photos once again without any problems.

• Acquire GigE camera data using labview CIN or DLL to call.

  I am tring to acquire data from a basler runner line CCD camera (GigE).

  Because the NI Vision Development Module is not free, and the camera provide a C++ API and C and also some examples, so I plan on using the function CIN or call DLLS in labview to achieve. Is this possible?

  I tried to generate a DLL with the example of the company code of the camera. But encounter difficulties;

  I did that a little background in C++, but not familiar with it. The C++ Code example provides the camera is a C++ (a source Code file) and a .cproj file, it depends on other files, the camera API directory.

  If I build the project directly, it will create an application window, not in a DLL. I don't know how to convert a DLL project, given that other information such as dependence in the .cproj file, other than source code.

  Can someone help me with this?

  Don't forget that for the acquisition of a GigE camera, you must only Module of Acquisition of Vision, not the entire Vision Development Module. Acquisition of vision is much lower price and also delivered free with hardware NI Vision current (for example a card PCIe - 8231 GigE Vision of purchase). You need only Vision Development Module if you then want to use pre-made image processing duties. If you are just display, save images to disk, or image processing using your own code (for example to manipulate the pixels of the image in a table) you can do so with just Vision Acquisition.

  It is certainly possible to call DLL functions if LabVIEW by using a node called library, it would be quite a lot of work unless you are very familiar with C/C++. Since their driver interface is C++, you need to create wrapper functions in C in a DLL that you write. Depending on how much you want to expose functions, this could be a bit of work.

• the digital camera driver does not load when a sony camera is connected to the computer vista laptop.

  At the same time the downloaded movies netflix has more audio.  Device Manager does not display a driver of the camera when the camera is attached via firewire and running?  I tried to reload the drivers and worked with the pilot web-based updates.

  Hi mstradt,

  1. which version of the operating system are you using 32-bit or 64-bit?

  2. What is the model of the camera number?

  3. you try to use the camera of Sony for the first time?

  4. How do you try to connect the camera?

  You can first try connect the camera with the different port and check if it is detected.

  Also try to use only Sony 4 firewire cable 4-pin to connect the camera.

  You can also visit the following links and see if it helps:
