MX Cameras

Vicon MX Hardware System Reference 3-9

Camera Lens Filters

In order to optimize the performance of the MX cameras, each lens

is fitted with an optical filter to attenuate wavelengths of light other

than those emitted by the light emitting diodes (LEDs) in the MX

strobe unit and reflected back from the markers to the camera.

Shuttered MX cameras (see Table 3-1 on page 3-2) are less

susceptible to interference from background light levels. These

cameras are fitted as standard with low-pass absorptive filters

(allowing low-frequency light to pass) appropriate for each of the

Visible Red (VR), Near Infrared (NIR), and Infrared (IR) strobe units

available (for details, see Camera Strobe Units on page 3-14).

Unshuttered MX cameras (see Table 3-1 on page 3-2) are potentially

more susceptible to background light. Therefore, a more restrictive

band-pass interference filter is fitted as standard to the these

cameras, appropriate for each of the VR, NIR, and IR strobe units

available. When using an unshuttered MX camera under well-

controlled lighting conditions, it may be appropriate to replace this

band-pass interference filter with a low-pass absorptive filter to

maximize the amount of strobe light returned to the camera sensor.

Camera Controls and Connectors

This section describes the physical structure of Vicon MX cameras and

the connections and cables that are used to connect them to other

system components.

Vicon MX cameras have been designed to consolidate all video and

strobe functions in a single unit and to automatically set strobe

durations and video frame rates directly from the Vicon software on

the host PC.
