CCTV Operator
What you'd actually do
The work is monitoring multiple screens, spotting suspicious or dangerous behaviour, operating cameras to follow incidents and radioing or calling the right people - security, staff or the police. Concentration, good judgement and clear, calm communication matter, as does careful record-keeping, since footage and your notes can end up as evidence.
Shifts often cover nights, weekends and bank holidays, the work is mostly seated in a control room, and staying focused through quiet hours is the real challenge. Pay is usually an hourly wage, often a little above minimum for the unsociable hours.
In the UK you generally need an SIA (Security Industry Authority) public space surveillance licence, which means approved training and a background check. Many operators start with a security firm or local authority once licensed.
