Hello,
My name is Ankit and I work for the Social Media and Community Team at Dell.
As you mentioned that you require the driver & the software for webcam on your dell system, then you can logon to the website for My Dell downloads.
To access this website, you can logon to www.smartsource.dell.com
It will ask you to register the system. So follow the instructions & then you will get all the basic softwares for the system which were shipped along with the system.
If you are unable to get the software on my dell downloads, then please follow the following link.
Dell_SX2210-Monitor_Webcam SW RC1.1_ R230103.exe
For any further queries, feel free to reply back on the post.
Thanks
Dell-Ankit
