LSE offers an automated lecture recording service called Echo360. If you are timetabled in a suitably-equipped room your lectures will be recorded automatically. If you wish to opt out from having your lectures recorded you need to complete the lecture recording preferences form in LSE for You.
Please note that only activities classed as lectures in the timetable will be recorded (except for the departments of Law, Finance and Management). For these departments, seminars will also be recorded, but not classes. You will need to opt out for seminars you do not wish to be recorded.
For other departments wishing to have classes, seminars or workshops recorded, please contact eden.lecturerecording@lse.ac.uk.
If any of your lectures is being delivered by a guest lecturer from outside LSE, please contact eden.lecturerecording@lse.ac.uk for advice on obtaining their consent.
More details about the lecture recording service, including the locations where it may be used, can be found here
Also, the Eden lecture recording team have produced a guide to using the lecture recording preferences page.
