CCTV must not be used to record conversations between members of the public as this is highly
intrusive and unlikely to be justified. You should choose a system without this facility if possible.
If your system comes equipped with a sound recording facility then you should turn this off or
disable it in some other way.
There are limited circumstances in which audio recording may be justified, subject to sufficient
safeguards. These could include:
Audio based alert systems (such as those triggered by changes in noise patterns such as
sudden shouting). Conversations must not be recorded, and operators should not listen in.
Two-way audio feeds from ‘help points’ covered by CCTV cameras, where these are
activated by the person requiring assistance.
Conversations between staff and particular individuals where a reliable record is needed of
what was said, such as in the charging area of a police custody suite6.
Where recording is triggered due to a specific threat, e.g. a ‘panic button’ in a taxi cab.
In the limited circumstances where audio recording is justified, signs must make it very clear that
audio recording is being or may be carried out.
