The Delhi government is planning to install CCTV cameras in schools for security purposes and to keep tabs on students and teachers' activities inside the classrooms, an official said here on Monday.

"We are bringing in CCTVs not just for the purpose of security but as tool which will help us to do a time on task study of how the teaching is going on in our class because we have to optimise and ensure that we don't waste too much resources," Delhi's Education Secretary Punya Salila Shrivastava said at an event.

Srivastava was speaking at a conference on "Quality Education for All-Role of Affordable and Accessible Technology" organised by The Associated Chambers of Commerce and Industry of India (ASSOCHAM).
