Lens control

Prosilica GT standard and long cameras

Prosilica GT standard and long cameras can be used with C-/CS-Mount auto iris

lenses of DC type, and P-Iris type.

Both DC and P-Iris lens types use the same standard connector, shown left,

located on the side of the camera. Lens type is automatically determined by the

camera on power-up. Connecting the lens after the camera is powered will not

damage the lens, but it will not be recognized by the camera; therefore, the rel-

evant camera control attributes will not function. If this occurs, disconnect and

reconnect the camera power supply.

Note



Video-type auto iris lenses are not supported.

Motorized CCTV lenses are not supported.

***Read lens descriptions carefully before purchasing***

For example, a “motorized iris lens” may be a bipolar single

axis motorized lens, and not a DC auto iris or P-Iris lens
