Increased frame rates: Selecting a frame rate greater than full resolution automatically reduces image size by windowing. This keeps the pixel rate the same by transmitting a greater number of smaller images per second. You specify the capture frame rate of the Vantage cameras in the Vicon application software. Vantage cameras are capable of capturing up to a maximum of 2,000 fps, but the actual frame rate you can specify depends on the Vicon application software you are using. For details, see your Vicon software documentation. Above 120 fps the amount of light emitted per frame is linearly reduced. The light emitted per frame at 240 fps is half that output per frame at 120 fps. (The total strobed light output remains the same).

You can instead Instead of (or in addition to) windowing, you can use high-speed mode, which uses subsampling to increase the frame rate without reducing the field of view, but with some reduction in resolution. For details, see High-speed mode and your Vicon software documentation.
Shuttering: The global shutter overcomes the negative effects of using rolling shutters for motion capture.

Full marker grayscale: Marker centers are calculated based on every pixel of grayscale available for the marker, not just the detected marker edges. An on-camera circularity test ensures merged or partially occluded markers which need high-level processing are sent in full grayscale to the Vicon Vantage host PC.

On-camera masking: This removes areas of the sensor where undesirable static light sources are recorded, for example strobes from other cameras.

Blob elimination: Camera firmware automatically removes undesirable image data including both large blobs (e.g. sunlight reflections) and/or an unusually large number of blobs.

Output modes: Automatic (centers for circular markers, grayscale for overlapping/partially occluded markers), Centers Only, Grayscale Only, Centers/Grayscale, and Preview (the entire sensor image).

Preview mode: The full image is lightly filtered, decimated and transmitted to the Vantage host at 30 fps. This reduces the quantity of preview video data to a level that can be transmitted over Gigabit Ethernet to the Vicon Vantage host PC. Only one camera at a time is allowed to be sent in Preview mode as it requires most of the system bandwidth to transmit this one signal.

Operating temperature: While Vicon cameras may operate outside the given limits, these are the temperatures to which Vicon has tested the cameras. If the cameras are operated outside of these limits, image quality may be degraded, the external surface temperatures may exceed the relevant safety limits, and any failures are not covered under warranty.
