If your lecture has been recorded, your department will provide you with a link to the recording, this is usually found on your module web site, if you use Moodle there may be a plug-in activated on the page. You can view the lecture on or off campus by following that link, in most cases you will need to be signed in to view it.
If your department is not currently using the Lecture Capture service to record your lectures you can request Lecture Capture here.
You can watch lecture recordings on Windows PCs and laptops, Windows phones, iPads, iPhones and Macs. If you are unable to view a lecture recording on your own device please email firstname.lastname@example.org
