If you have many IQeye cameras and would like to make changes to all of them you can use IQmanager's "Set OID" function.
First select the set of cameras that you would like to manage. Then right-click and select "Set OID". OID's are Object IDentifiers and are basically the variables used to configure the cameras.
For example, to set stream 1 resolution to 1080p you would specify OID 18.104.22.168.2.1 and for the value select 1080p. The values are the same options that you see in the camera web pages for the specific fields.
You can see the complete list of OID's and values for a camera by selecting the URL http://<camera_ip>/oidtable.html.
