A government spokesperson, however, said no videography took place during the Cabinet meeting at the Delhi Secretariat.
"The Home secretary pointed that the deliberations in the Cabinet meeting are confidential and the tape of videography of the cabinet meeting should be handed over to the Home department for a record so that confidentially could be ensured," said the source.
Sources said that in the letter, the home secretary has also cited Official Secrets Act provisions.
This was the first meeting attended by the chief secretary after he was allegedly assaulted by AAP MLAs in presence of Kejriwal at his residence on the intervening night of February 19 and February 20.
Delhi government's Finance Secretary SN Sahay also attended the meeting.
