9. CONTROLLING THE CAMERA (XCAP)
The sections below will give information on using each control of the Ninox 640 SU, giving a
description on how to use each control parameter and their effect on the camera’s
performance. The software used to illustrate the camera controls is XCAP.
9.1 Exposure Time and Frame Rate
The exposure time can be controlled under any camera control tab in the XCAP GUI and
remains constant on the GUI.
The minimum and maximum exposure times that the camera can set are shown in the table
below in Figure 6.

Frame Rate:
The frame rate can also be set using the frame rate user input box located
under the Trigger tab. By default, the frame rate is set to 25fps. The maximum frame rate of
the camera is 100fps. If an exposure time is selected that exceeds the exposure time limit of
the current frame rate set, then the exposure time will dominate, and the frame rate will be
decreased. Alternatively, if the user selects a frame rate that is too fast for the current
exposure time set, XCAP will decrease the exposure time.
