Local Images of IPC6525 Do Not Change After the Aperture Adjusting Buttons Are Clicked on PTZ

Publication Date:  2019-04-25 Views:  13 Downloads:  0
Issue Description
A customer reports that the output local images do not change after the aperture of the IPC6525 is adjusted by clicking the corresponding buttons on the PTZ.

It is found that the exposure mode of the ISP parameters of IPC6525 is Auto. Auto (default): The camera automatically sets the shutter speed, aperture value, and gain based on an object's exposure value measured by the metering system.

On the camera web UI, choose Configuration > Channel Configuration > ISP Parameters, and set Exposure mode to Aperture priority. Then, adjust the aperture again. The output images can be darker or brighter.

Aperture priority: Users manually choose a specific aperture value, while the camera then automatically selects a shutter speed and gain to match. This mode is used to shoot static objects.
