I am looking for a video camera that will have: * 15 or higher frame rate * 2 Mega pixel resolution or higher * Kodak sensor * GigE connection * ability to function well at air temperatures or around 60 C * up to 3,500$ * low-light / night and size not very important. Thanks!!
Hi Einat, Thanks for your question! I must thank you for your thoroughness in selecting a camera. It sounds like you've done a lot of homework to come to these specific requirements. We currently offer a couple cameras that could fit these: piA1600-35gm/gc - 1600x1200 - KAI-2093 Sensor - 32fps - GigE - mono & color piA1900-32gm/gc - 1920x1080 - KAI-2020 Sensor - 35fps - GigE - mono & color We also have in that series the Sony ICX625 sensor: piA2400-17gm/gc - 2456x2058 - ICX 625 - 17fps - GigE - mono & color You can find more information here as well: http://www.baslerweb.com/beitraege/beitrag_en_48495.html 60C is indeed a hot environment. Can I ask what the application is? Typically, machine vision cameras are designed slightly more robust than normal electronics, and can usually be run fine in environments of about -10C to 60C. Ours for example offer a completely metal housing which helps dissipate heat.
Hi, we have 6 Basler Vision Technologies cameras. Two are each connected to a PC, and four are each connected to a PC. On each PC Wireshark tells me that the PC's are sending an "GVCP 62 Resend request". No matter which NIC we're using. (3Com PCI-X, Realtek 1x PCI-E, Basler Onboard NIC's). So the result is a frame dropping. Please help.
Hi Marcus, Interesting error. The packet size parameter is also a good starting point when troubleshooting any network issue (start at 1500 as it is more or less a fail-safe value), but in this case I don't expect too much to improve. This is because GVCP uses packet sizes of 576 always for sending control commands. The usual 'packet size' parameter refers to GVSP for image transmission. Instead what I would try is to set the transport layer read and write timeouts from 500ms to about 20ms (if you are using our pylon driver). In rare cases we've seen a buggy nic hold the camera's acknowledgment message to a GVCP command (like 'set gain'). Resending it 'pushes' the first ack through. Reducing the timeout will make the driver resend the command more quickly. It might not apply to you since you are trying different nics, but it's worth a shot. if it doesn't work, please contact me at firstname.lastname@example.org. I hope this helps though.
I am looking for a very small size, highly integrated IR camera system/module for 100k unit per year application. The application is low performance machine vision on reflected IR light. lens and focusing mechanism must be included. Resolution needs to be 1080p class and 30 fps or less is OK. It needs to have a simple serial digital interface and simple DC power supply requirements... Can you recommend one? Thanks Very Much
Hi Kevin, We currently don't have a standard product exactly like this, but if you have some time, I would like to learn more about the application and the requirements. You'll find from this site and others that classic core machine vision applications are still primarily PC based and designed around common interfaces like GigE, FireWire, USB, etc. But as technology gets better and smaller, true embedded applications like this are becoming more common. Personally I find this very interesting and would like to know more. Besides that though, I only know of some low-end cameras that use UART or SPI for things like robotics, etc. But not many of them go beyond VGA resolution and single compressed jpg images. My guess is a company might have to build a custom camera for you to bring in the quality needed for processing (that I can say we do all the time :)) That being said, please feel free to contact me if you think I can be of assistance. - Matt
I am looking for a Camera Link camera based on the new Sony ICX-674 CCD. Does anyone know of any? (I've evaluated cameras based on the Kodak KAI-02150 CCD, but am not happy with the image quality (tap balance).
Hi John, We don't make a cameralink camera with the ICX674 (just 1394 and GigE), but if you ever would like to give the KAI-02150 another shot, we spent what I would consider a great deal of R&D resources solving the tap balance issue. It was the key focus of integrating these chips. There's a whitepaper on it here if you're interested: http://www.baslerweb.com/downloads/32541/BAS1105_4Tap_Channel_Balancing.pdf Feel free to contact me if you think I can help further. - Matt
In our optical system we have observed that when we replace the B/W camera with a higher resolution camera (same optical format but smaller pixel size and larger pixel) we observe a much more gray image, the image has much less contrast with the high resolution camera. Example substituting a 2MP, 1/4 " optical format with a 5MP, 1/4 optical format causes a much less contrast and detail. How do we adjust for this?
Hi Mike, My first thought is that there's a few things at play here besides just the increased resolution. Mainly that each sensor is different, and tends to have their own performance specs. So I would need to know some deeper details of the sensor models to be sure, but there are a couple things your could try in general: - Any chance the software you are using has some post-processing contrast enhancement? - You could try to increase the aperture size of the lens. - Reduce the black level (or brightness) setting. - use a lookup table (if the camera provides one) to custom map the output pixel values. If you would like, feel free to contact me. Even if you are not using our brand of cameras, it's possible that we are using the same sensors as the ones you do have (there are not many 1/4" 5MP sensors in the industrial camera world :) ). If so, maybe I can at least provide some of our test data to help give an idea of what to expect in general. I hope that helps! - Matt
Why can PoCL not be used in medium or full mode?
Hi Balamurali, It's not so much that the medium or full modes are preventing PoCL from being used, but PoCL's standard only allows for 4W of power. Typically the cameras that take advantage of medium/full modes are drawing more than that due to the sensors & electronics being used, although that's not always the case. In any event, 4W is the limit. Hope that helps! - Matt
My name is Ken Schuler, I am working with Orion Tech to see if we can find the right combination of camera/sensor/lens for a project we are working on. We had a sales rep, Kiran Devkota, but his phone disconnected. Here are some of our requirements; Camera *monochrome, decent resolution sensor. *USB interface. *IR capabilities, unit will be operating in darkness under an IR source. *C or Cs mount depends on the type of lens. Lens *A focal point of 90mm. *A field of vision of 35mm at the 90mm. *A Depth of field of at least 6mm. Any help you could provide would be much appreciated. Thank you, Ken Schuler Noss4ra2@gmail.com 302.757.9544
Hi Ken, Thanks for all of the information! Good news, there are a lot of camera / lens options out there that will hit those requirements nowadays. We can narrow it down further once we know your target for resolution and framerate, and the application itself. Feel free to drop us a line and we can discuss further. Have a good weekend, and greetings from Wilmington!
We want to integrate a GigE Basler camera (SCA1400-17GM) into one of our system (connection to one of our OEM motherboard cards). What is the procedure to get the reference software source code in order for us to develop under GigE environment?
Hi Gil, This is no problem. Please contact me directly at email@example.com and I can set you up with the SDK and put you in touch with local support to assist you.
I am using a network sniffer and seeing a lot GVCP discovery pings on my network. The packets are using broadcast address. Is there a way to control GVCP pings to the local segment which the cameras are on?
Hi Ken, Both broadcast and unicast discovery messages are supported via the GigEVision standard, so theoretically it should even be possible to send a discovery message to a specific ip address (even if it is on a different network, like crossing a router). The best bet though is to check with both the driver manufacturer and camera manufacturer (if you're using third party software) to see if / how it's implemented in their tools. I hope that helps!
When I turn on my camera and connect to the router, the router has an address of 192.168.1.1 with a subnet of 255.255.255.0, but the IP address of the camera is 169.254.148.140. I want to send a device discovery broadcast message on port 3956 through the router. Problem is, it does not get to the camera because it is not in the subnet. Is there any way to make this happen?
Hi Antony, Depending on the manufacturer & model of your camera, it could be possible to 'jump subnets' like this, so I would check with your vendor to find out what might be possible there. We've added this feature roughly a year ago to our products, so it could be that others are seeing the use for it as well. As a tip though, routers tend to block these types of broadcast messages as part of their firewall purpose. A unicast message send directly to the ip address should get through. If possible though, I would recommend using a network switch instead of a router. I hope this helps!
Dear ladies and gentlemen, we are using cameras with your standard in our x-ray systems. Our current preferences are cameras of the suppliers Basler AG & The Imaging Source. Both suppliers are implemented in our product lines. Unfortunately cameras of each single supplier are only working with their special software. This means whenever we implement Basler Software there will be detect only Basler products. Same with The Imaging Source. Even though all companies are working with same standard the manufacturer make sure that only won product will be detected. How is the procedure to arrange software which is not limited on specific manufacturer?! Thanks for your efforts. Mit freundlichen Grüßen / Best regards i.A.

Hello Sven, John is correct in his reply. A neutral 3rd party SDK is very useful when comparing cameras like this. Honestly, what you are seeing is unfortunately the nature of competition. Although many of us are building to the same standards, there usually are some provisions built in such that a camera manufacturer's software only detects their cameras, at least on the surface. This is because we are all testing our software with our own cameras, and so we can't guarantee performance if another vendor is used (although theoretically it could work). However, I will also pass this question along to our support colleagues in Germany. We always aim to make evaluations go as smoothly as possible, so if we can, we like to help! Thank you for the interest in Basler btw! - Matt
Is it possible to create a network switch that can modify the control packets? We are trying to make our own special device for our own controlled environment to achieve a higher level of safety .
Hi Farrukh, I have not heard of such a device before, but I guess in theory perhaps it can be done. Switches are already doing QoS based on different protocols, and GVCP/GVSP are more or less just two more. What are you aiming to do with the packets?
Have 5 axis, 5'x10' table, CNC router trimming plastic parts. Would like to explore mounting a sensors, cameras, or lasers on the mast that can measure the router bit location to an accuracy of +/- .002. Would also like to put targets or sensors at the extents of the table to measure table location at rest or at a programmed fixed position.
Hi Ken, Just a tip, this would be a perfect application to talk to an integrator about. The company I work for just makes cameras, but I've seen many applications similar to this over the years. I'm not certain if you would need actual cameras, or if you could get away with some simple sensors, but those guys are definitely the ones who can solve the "it depends" questions :) Check the 'Find a System Integrator' link http://www.visiononline.org/search-integrator.cfm. The names I'm seeing there are very reputable and I've personally worked with many of them before. If you get stuck, feel free to email me and I can try to help get you in touch with the right people. Good Luck!
Investigating if a vision system exists or can be developed which can scan various electrical connection systems and determine if the connector is fully mated. The scanning device needs to be portable and self contained such that an operator can be free to move from vehicle to vehicle checking multiple connections and connector types at various angles and/or orientations.
Hi Bernard, It sounds a bit tricky because the environment (lighting, orientation, etc.) will probably change a bit as the setup is moved around, but I've seen integrators out there take on similar projects. So it sounds feasible to me. If you'd like, drop me a line and I can help point you in the right direction. Hope that helps! - Matt
