The Phantom S991 delivers 9 Gpx/sec (70 Gbps) of throughput and the power of the Phantom Flex 4K sensor with CXP-over-fiber technology for extreme high-speed imaging.

  • Up to 937 fps at 4096 x 2304 (8 bit)
  • 6.75 micron pixel size
  • Rolling or Global shutter 8- and 12-bit selectable
  • User friendly CXP-over-fiber technology

The Phantom S991 builds on the industry leading technology of the S990 by incorporating fiber cables for data transfer.  The two fiber cables are easy to connect and can carry up to 70 Gbps of images and data to the frame grabbers.  This significantly improves setup and ease of use. 

Imaging flexibility is enhanced through adjustable capacity settings.  Using just 1 fiber cable for 1/2 capacity operation (4 Gpx/sec) allows researchers to achieve full frame rates at smaller resolutions while full capacity operation (8 Gpx/sec) offers large to maximum resolution for highly detailed imaging. 

CXP-over-fiber delivers the immediately accessible imaging a simple process by dividing it between two frame grabbers then stitching them back together. The image is then stitched back together for fast algorithm application which means no waiting to download data to apply critical decision-making algorithms.

Using 2 fiber banks delivers the full power of the Phantom Machine Vision cameras, but you do not need to use both fiber banks in all use cases. You need to use both banks to reach the maximum frame rate at very large resolutions or reach the maximum frame rates at many resolutions using 12-bit output. However, you only need 1 bank for most scenarios using 8-bit output, smaller resolutions, or frame rates lower than the maximum. 

The S710, S640, and the S990 use a bit more power than typical machine vision cameras, so they do not have Power over CXP. They use 20-28 VCD. You may either supply your own power or use the power supply provided with the camera.

The S210, S200, S640, S710, and S990 don’t use PCC – PCC communicates to traditional Phantom cameras using the telnet interface and our telnet protocol, while these cameras are controlled through the GenICam protocol, then users can process the images directly on their systems.

We test the ISO of every Phantom camera model to the industry standard ISO 12232. We use the SAT method which we believe is the best method for determining a sensor's sensitivity. The SAT method does not use gain to boost sensitivity. When using gain to increase sensitivity, you also boost the noise level. A gain adjustment to boost sensitivity is available on all Phantom cameras using image processing tools, if increased noise can be tolerated.

Per the spec, we will often publish both a Daylight (D) and a Tungsten (T) value because the source of illumination has a significant bearing on the result, particularly with monochrome sensors. When T or D is not specified, it can be assumed that the value published is the Daylight variant.

Please note that most modern Phantom cameras include Exposure Index control, which will boost the apparent ISO through the use of pre-defined tone curves that get applied to the raw images. The exposure index (EI) range is specified by Vision Research per camera model to ensure optimal image quality throughout the range.
We do not manufacturer specialized enclosures such as underwater housings directly. There are manufacturers of underwater housings on the market compatible with Phantom cameras. Here are a few examples:

Gates has a specialized housing for the Flex4K: https://www.gateshousings.com/flex-4k/

Nauticam has an underwater housing for the Phantom VEO (all S-model VEO) https://www.nauticam.com/

Prevco is a subsea engineering consultancy and manufacturer specializing in submersible pressure vessels, instrumentation housings, junction boxes, vent plugs, pressure relief valves and other accessories, also compatible with Phantom cameras

If you supply underwater housings or know of another supplier, please let us know so we can add to this list.
Most Phantom cameras come with a fixed amount of high-speed dynamic RAM. When the camera is in the pre-trigger mode (you've pressed "Capture" in the user interface), the camera is continuously recording images into that memory. When it gets to the end of memory, it cycles back to the beginning and continues recording, constantly overwriting itself – until the camera is triggered. This behavior is called "circular buffer recording".

What you end up actually saving in memory is a function of how you've set up your trigger. It can be set so that only frames that occur after the trigger are saved (100% post trigger). In this mode, once the trigger is pressed any images already in memory are overwritten and you record until memory is full, then it stops. If you set the trigger to stop the recording (0% post trigger) and save all frames up to the time of the trigger, the camera will simply stop recording upon the trigger and all the frames in memory before the trigger will be saved. Finally, you can set the trigger anywhere in the middle, for example having 90% of the recorded movie be what happens prior to the trigger and 10% after the trigger.
Yes you can!  Information on discontinued Phantom cameras is archived. Information on most legacy products can be found in the ‘Support by Model’ section at www.phantomhighspeed.com/support
The Phantom RCU is a legacy solution for Flex, Miro and v-Series models. The Bluetooth dongle that was designed for the RCU also works with the handheld PCU from AbelCine, which is also compatible with most modern Phantom cameras. The Bluetooth dongle is needed for wireless connectivity with the RCU or PCU and connects to Phantom cameras with a “Remote port” (v-Series, UHS and Flex cameras). Note that Miro and VEO camera models do not have a ‘Remote’ port directly on the camera body. However, VEO cameras can be connected using the CAMEO VEObob accessory.
There are two third-party solutions that Vision Research recommends highly because they work for ALL Phantom cameras over their Ethernet connection:
  • The Semote handheld remote controller includes a handheld unit and camera unit to transmit the signal. This device provides a connection up to approximately 30 meters.

  • The iPhantom app works on any Apple IOS device, and connects to any Phantom camera that has a WiFi router attached to the camera. This is particularly great for VEO S-model cameras (with firmware after version 106), because those cameras include a USB port for a USB WiFi dongle available from Vision Research.

We offer hands-on training for Phantom cameras at our Wayne, New Jersey facility. The two-day class has both lecture and labs for the best learning experience. This class is targeted at applications where the cameras will be used for scientific and engineering applications.
On-site training is available.

For customers outside of North America, who prefer local training, most of our International Sales Partners offer training courses tailored to your needs.

If your application is TV or Motion Picture production, consider training courses targeted at those applications from AbelCine, or other Phantom resellers around the world who focus on the "entertainment" market.
