MXhardware_Reference.book Page 3 Thursday, September 7, 2006 11:36 AM Introduction Vicon MX Architecture Models You can combine Vicon MX and third-party elements to create an architecture that meets your application requirements. This modular approach enables you to expand Vicon MX as needed. The following sections illustrate some common Vicon MX architecture models.
MXhardware_Reference.book Page 4 Thursday, September 7, 2006 11:36 AM Introduction Large Camera-Count Architecture If your application requires more than eight MX cameras, you must include additional MX Ultranet units in the Vicon MX architecture. If your system has an MX Net unit, you must include additional MX Net units along with MX Link units to connect these together. For descriptions of these system elements, see Vicon MX Architecture Elements on page 1-1.
MXhardware_Reference.book Page 5 Thursday, September 7, 2006 11:36 AM Introduction Integrated Third-party Application Architecture If your application integrates third-party analog capture, genlock, and timecode devices, you must include an MX Control, with the appropriate option card installed, in the Vicon MX architecture.
MXhardware_Reference.book Page 6 Thursday, September 7, 2006 11:36 AM Introduction Integrated V-series Cameras Architecture If your application integrates Vicon MCam2, VCam, SVCam, MCam(PAL), or MCam(NTSC) cameras supported previously by Vicon V-series systems, you must include an MX Bridge in the Vicon MX architecture (for descriptions of these system elements, see Vicon MX Architecture Elements on page 1-1). This integrated V-series cameras architecture is illustrated in Figure 1-4.
MXhardware_Reference.book Page 1 Thursday, September 7, 2006 11:36 AM 2 MX Bridge 2 This chapter describes the physical structure of the MX Bridge, including its connections to other Vicon MX components and to supported V-series cameras. The MX Bridge provides the interface between Vicon MX and any MCam2, VCam, SVCam, MCam(PAL), and MCam(NTSC) cameras supported previously by Vicon V-series systems.

MXhardware_Reference.book Page 1 Thursday, September 7, 2006 11:36 AM 3 MX Cameras 3 This chapter describes the MX+ and MX cameras, including associated strobe units, connectors, and cables. Warning There are no internal operator adjustments inside any components of the MX cameras. Refer servicing to qualified personnel.
MXhardware_Reference.book Page 2 Thursday, September 7, 2006 11:36 AM MX Cameras All cameras are high-quality devices, fitted with sensitive solid-state sensors. Vicon Motion Systems subjects its cameras to stringent checks for linearity, sensitivity, and absence of jitter. All MX cameras provide high-speed and low-latency motion capture. You can combine the different types of MX camera within a single Vicon MX system to meet your application requirements for resolution and/or coverage.
MXhardware_Reference.book Page 3 Thursday, September 7, 2006 11:36 AM MX Cameras Performance Notes: • Shuttering: The image quality from a shuttered camera is constant across all frame rates. For an unshuttered camera, which is more susceptible to background light levels, narrow bandwidth interference filters are used to provide a signal to noise ratio performance comparable to the shuttered cameras. Factors such as strobe illumination, field of view, and depth of field also affect the image quality.
MXhardware_Reference.book Page 4 Thursday, September 7, 2006 11:36 AM MX Cameras the software documentation. • Synchronization: Cameras are automatically assigned master (controlling device) or subordinate (controlled device) status. Each Vicon MX system has only one master device, which provides the synchronization to the rest of the system and is established automatically during system booting. The master device is an MX Camera, or an MX Ultranet if present, or an MX Control if present.
MXhardware_Reference.book Page 5 Thursday, September 7, 2006 11:36 AM MX Cameras The focal length determines the angle of view (AOV) through the lens, as shown in Figure 3-2. Figure 3-2: Angle of View calculation Normally, the AOV is calculated based on the known focal length and sensor size. This in turn determines the FOV, based on the distance (L) to the object being captured. Figure 3-3 illustrates how the FOV is calculated.
MXhardware_Reference.book Page 6 Thursday, September 7, 2006 11:36 AM MX Cameras The sensor area used for capturing data through each MX camera determines the maximum FOV available for a particular combination of camera and lens. The area of the sensor is determined by its horizontal width (h) and vertical height (v). The capture frame rate for each MX camera can be configured in the Vicon application software (for details, see the software documentation).
MXhardware_Reference.book Page 7 Thursday, September 7, 2006 11:36 AM MX Cameras and corners is lost. MX cameras are fitted with lenses that have an appropriately sized image circle for the sensor. If you wish to change the supplied lens, you must consider the sensor size of the new lens. Even if the focal length of the new lens is the same, a different sensor size will produce a different field of view.
MXhardware_Reference.book Page 8 Thursday, September 7, 2006 11:36 AM MX Cameras • Horizontal FOV at 9m would be: 16.5 x (9/20) = 7.43 m • Vertical FOV at 9m would be: 12.1 x (9/20) = 5.44 m Important These formulae take into account only the optical components of the camera and lens, thus they calculate the maximum possible theoretical Field of View from this combination.
MXhardware_Reference.book Page 9 Thursday, September 7, 2006 11:36 AM MX Cameras 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.
