Question to the Home Office:

To ask the Secretary of State for the Home Department, whether her Department has made an assessment of the potential merits of using or procuring (a) Hikvision or (b) Dahua surveillance technologies.

As has been the case under successive administrations, it is not government policy to comment on the security arrangements of government buildings. Specific details regarding the make and model of security systems procured and used by the Government are withheld on national security grounds.

The National Cyber Security Centre and the Centre for Protection of National Infrastructure provide guidance on the use of IP-connected cameras and cyber-connected physical security systems.
