10 GigE Vision compliant cameras are easy to integrate enabling more machine vision applications and image processing. Camera image sensors have continued to increase in resolution which requires higher bandwidth interfaces to achieve high frame rates. 10 GigE cameras are a great solution as implementation is less costly and complex versus camera link and CoaxPress.
Aside from the features of 10GiGE Vision, the Baumer VLXT series cameras are extremely feature rich and cost competitive making them an excellent choice for 10GigE Vision cameras.
11 Key Features are listed below with many being unique, solving more vision applications in 10 GigE Vision cameras
1 – True 10GigE bandwidth! – 2 – Liquid lens & Canon EF mount control 3 – Exposure times down to 1uS with Sony Sensors 4 – Power outputs (4x) for direct driving LED lights eliminating a lighting controller. 5 – IP67 Ratings and extended temperatures for harsh environments 6 – IEEE 1588 Precision Timing protocols for synchronized timing with multiple devices. 7 – Long cable lengths up to 55 meters (Cat 6) and 70+ meters with Cat 6a / 7 and longer with optional fiber optic interface. 8 – Standard low cost 10GigE NIC’s can be used opposed to some manufacturers requiring special NICs 9 – Fully GigE Vision compliant for easy implementation with the benefits of high bandwidths. Allows support of third party software libraries. 10 – RS232 support 11 – On board JPEG compression available
Machine Vision standards have evolved providing defined models of how industrial cameras communicate to a PC allowing easier implementation of machine vision technology. Vision systems can be made up of cameras, frame grabbers and vision libraries from various manufacturers. The vision standards provides compatibility between the various manufacturers for easy implementation.
Machine vision applications require some basic tasks of finding and connecting to the cameras, configuring parameters, acquiring images and dealing with events to and from the cameras.
In order to provide cameras from various manufacturers to work together with 3rd party software and hardware from other manufacturers and provide the tasks above, a standard must be followed. “GenICam” is the basis for this standardization, providing compatibility using a Generic Transportation layer and Generic Application programming interface. These are referred to as “GenTL” and “GenAPI” respectively. GenTL provides the communication layer and GenAPI enables camera features to be configured by analyzing a compliant XML file for the camera.
Camera manufacturers however provide unique independent features providing various advantages from one to another. Creating these unique features blur the lines of the standard, not always making a camera fully compatible with another manufacturers software. For example, an industrial camera may use the GenTL layer to be recognized but may have special features making it unique as well.
While not an exact figure, we would estimate that about half our client’s problems with machine vision camera connections, dropped frames, etc. comes back to a cabling issue. This is especially true for USB and GigE cameras.
In most of these cases, the issue is that the user is using a poor/low quality cable that was not made for the high speed and/or long distance demands of the application. Most of the inexpensive cables available via mail order are not made for use in high speed highly reliable data transfer applications. If your phone isn’t transferring at the full USB3 bandwidth, you normally don’t care. You probably don’t even know. But when you purchase a high speed USB3 camera and you can’t achieve its full frame rate, or you achieve it intermittently, this becomes a big issue.
This is the reason 1stVision offers ‘machine vision/industrial’ USB3 and GigE cables. These cables are tested to specs, come with screw locks to prevent the connectors from falling out, use larger gauge wire, are over molding and have die cast aluminum shells. They are designed to be twisted and bent (somewhat) and are industrial!
Watch this 1-minute video to understand what we mean by “Industrial”
Signal amplitude (the voltage of the signal in the cable) is a function of distance and frequency for cables. For instance, Ethernet is specified to 100 meters. So your cable should work when each device is 100 meters away. However, without the proper cable, you will not maintain the full 1000 Mbits/s data transfer rate! You might only be getting 50% of the speed depending upon the distance without a high quality cable.
Finally, consider the cost if your machine vision camera is part of an instrument or product that is being sold to your clients. We see far too many clients who try to save $30 on the cable only to find out that it is costing them thousands of dollars to trouble shoot a problem that can be easily solved with the proper part. Not to mention the cost to their client when the system isn’t working, and a hit to their reputation of not building a reliable system.
Here is our advice:
If you are in an industrial setting, you are compromising the reliability and robustness of your system if you are not using an ‘industrial cable’. Even if you are not operating at maximum speed of the camera, you should have these cables. BTW, these cables are not that much more expensive mail order cables. They are in the 10’s of dollars, but not in the 1’s of dollars.
If you are using USB3 cables, you should really be using ‘industrial’ cables. Current ‘inexpensive’ USB3 cables are not reliable at over 2M, and only 1M for USB C connector types. If you are using USB3 specifically to get the higher speeds from this protocol, then you absolutely need to be using ‘industrial’ cables. Inexpensive cables are not reliable for high speed data transmission.
If you are in a lab environment, with the cable never moving, and only going a short distance, then a high quality ‘inexpensive’ Cat 6e cable will work. There is a difference between inexpensive Ethernet cables. The one that came with the security camera all folder up is NOT what you should use. A reputable mail order cable vendor selling high quality patch cables is OK.
These latest Nano models offer 2.4 MP (1936 x 1216) resolution with a GigE interface in color and monochrome with up to 102 frames per second utilizing TurboDrive.
What’s so interesting about the Nano M1950 and C1950 models?
2.4 MP resolution with the speed of the popular IMX174, but at the price of the IMX249:
Sony Pregius image sensors in a given resolution has created paired sensors, one being faster at a higher price and one slower at a lower price. The Nano M1940 / C1940 cameras use the IMX174 which is a great sensor and historically had the fastest speed at 2.4MP in GigE, but at a premium. We could opt for the Nano M1920 / C1920 cameras with the IMX249 at a lower price, but sacrificed speed.
Until now! – The latest Nano M1950 / C1950 models with the IMX392 provides the higher speed of the M1940 / C1940 cameras, but at the lower price of the Nano M1920 / C1920 cameras.
2.4MP resolution using a 1 /2 in sensor format, provides cost savings on lenses.
Thanks to the Sony Pregius Gen 2 pixel architecture, the pixel size is 3.45um, allowing the same resolution and eliminating the added cost of larger format lenses found in the IMX174 / IMX249 sensors which were 1 / 1.2″ formats.
When would you use the Sony Pregius IMX392 versus the IMX174 and IMX249 sensors?
The Sony Pregius IMX174 / IMX249 images still have an incredible dynamic range due to the pixel architecture found in the first generation image sensors. (Read more here on Gen 1 vs Gen 2). If you need dynamic range, with large well depths of 30Ke-, then use the IMX174 / IM249 sensors.
I’m so confused! Where can I get the specs on the new Nano M1950 / C1950, understand what sensors are in what cameras and get a quote?
The tough part today, is that there a ton of model #’s in the Sony Pregius sensors lineup and in turn camera product lines. Here’s a brief table to help with links to spec’s, related image sensors and a link to get a quote.
