Hello Alastair. I'm Greg, here to help you with this.
I'll give you all possible fixes that are working for others for webcam problems. If you need help performing any steps I am standing by to help.
- Try Updating the webcam driver from the PC maker's Support Downloads web page for your full model number, Serial Number, or Dell Service Tag number from sticker on PC.
In Device Manager reached by right clicking the Start button, compare all other drivers including Chipset, display, sound, etc to make sure you have the latest vs. the PC maker's Support Downloads web page.
Additionally on Webcam Driver tab see if Roll Back is available, if not try Update Driver, first Automatically, then Browse, then Let Me Pick to try all previously installed Drivers.
If these fail try to Uninstall the Driver, restart PC to reinstall.
- Did you enable the Privacy setting to allow apps to use your webcam?
