The camera's acquisition frame rate
In addition to the maximum allowable bandwidth of the network and the time limit for camera acquisition,
the exposure time can also affect the frame rate. For example: for MER-200-20GM/C-P camera, when the
exposure time is 100ms, the corresponding frame rate is 10fps.
In conclusion, the frame rate of the camera takes the minimum of the maximum allowable frame rate of
the network, the acquisition frame rate and the exposure frame rate.
