    For the videoinput GigE adaptor, ExposureTimeAbs is a standard GenICam property.
     
    The units are set by the camera manufacturer per the GenICam SFNC standard. You can use the PROPHELP function to get info on a property (this inf is also provided by the camera manufacturer in the camera XML file). For example, here is the output with a camera I have on my desk. The units for ExposureTimeAbs are in microseconds.
     
    >> v=videoinput('gige',1);
>> s=v.Source;
>> prophelp(s,'ExposureTimeAbs')

ans =

'EXPOSURETIMEABS double [31 1000000] (Read-only: notCurrently)
Sets the exposure time in microseconds (us) when ExposureMode is set to Timed.
See also PROPINFO, and ExposureMode.'
