Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many CCTV cameras manufactured by (a) Hikvision and (b) Dahua are installed on his Department's sites.

We take the security of our personnel, systems and establishments very seriously and have a range of measures in place to ensure the integrity of our arrangements. These measures are kept under constant review and adjusted according to the threat. It is, however, long standing policy that we do not comment on the detail of those arrangements.
