My name is Ankit and I work for the Social Media and Community Team at Dell.
As you require the installation software for webcam, would request you to visit www.smartsource.dell.com
You need to create your account & register the system.
Once the system gets registered, you will get all the list of basic software’s which were shipped along with the system.
You can also follow this link to install the driver:- Dell_SP2309W-Monitor_Webcam SW RC1.1_R229400.exe
This link is for generic drivers and is compatible with your system.
Hope that resolves the issue.
