The Phantom Miro C321J and C321 provide high quality HD imaging for on-board auto crash testing and a range of other applications. The small, rugged cameras work perfectly within established Phantom imaging solutions for additional flexibility. 

  • 1480 fps at 1920 x 1080
  • Exposure Range:
    • Mono 10,000 – 50,000
    • Color 2,000 – 10,000
  • Memory Capabilities:
    • 8 or 16 GB RAM
    • 240 GB internal, non-removable CineFlash
  • Internal battery for data protection

The Phantom Miro C321J and C321 are the next evolution in offering 3GPX/sec throughput, with a maximum frame rate of 1480 fps at full 1920 x 1080 resolution. These cameras provide very high quality, low noise images, and include an ability to set a new CSR default that provides a high-quality image right at boot-up for fast and convenient set-up. They are small, rugged, and built in the same form factor as other Miro C cameras, making them perfect to incorporate into already established automotive crash test imaging solutions. Tested and proven to withstand shocks of up to 170G and vibration of 24 Grms, the cameras also come with an internal back-up battery and Flash, to ensure critical test images are captures and saved.

The cameras use a sensor with tightly packed 10 micron pixels for great light sensitivity. When combined with advanced features shots are delivered quickly with clear detail. 25 shots can be saved into the 240GB Flash before downloading is required, ideal for situations with repeat setups or experiments. These new features can help improve speed and image quality both on the auto test floor and in cutting edge laboratories. The combination of on-camera battery and the non-volatile Flash keeps data safe in the event of power loss. 

Key Features:

  • High quality images
  • 1920 x 1080 resolution
  • High sensitivity
  • Tested to 170G Shock

The Miro C’s do not have a mechanical shutter. This allows them to be as rugged as they are but can make a CSR for good image quality inconvenient because you need to cover the lens. When you turn the camera off, the CSR returns to the factory default. 

For customers that rarely change their camera settings, the “Set new CSR default” feature provides a convenient alternative to this process. You must operate the camera at full resolution, for example 1920 x 1080 for the C321. You may then set the CSR for the frame rate and exposure time you are using. That CSR will remain through turning the camera off and on, for as long as you don’t change that setting. Always run at 1000 fps and a certain exposure, for example? Set CSR once, get great image quality, and don’t worry about it again, no matter how many times you turn the cameras on and off.  

Yes! We have an economical upgrade. Just contact your Phantom service team or Sales team member for details. 

The Miro Junction Box 2 (VRI-Miro-JB-2) accepts up to 6 Miro cameras at once.  The Miro C321J, C320J and C210J use a System Cable, while all other Miro cameras require a system adapter cable.  

Up to 4 VEO S-model cameras are also compatible with the Miro-JB-2 (not the original Miro-JB).  An adapter cable is required for each camera.  

VEO L-model and V-Series cameras are not compatible. 

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.
