Information sign
Security signs
Security signs warn, inform and remind. This set covers alarms, private property, security patrols, visitor sign-in, keeping a door locked and "no valuables left in vehicles". Each is a PDF in A5, A4 and A3, portrait and landscape. For cameras see our CCTV signs, and for keeping people out see No entry, Keep out and No trespassing. Only use a sign that is true: do not say premises are alarmed or patrolled if they are not.

Print tips
- Print at "actual size" or 100%, not "fit to page", so the margins stay even.
- Use thicker paper or card (160gsm or more) if the sign will be handled.
- For outdoor or long-term use, laminate it or buy a rigid version.
Where to use it
- Gates, yards and storage compounds
- Reception desks and building sites (sign-in)
- Car parks and garages
- Cupboards, stores and equipment cabinets
- Homes and outbuildings
Questions
Where are the CCTV signs?
On our CCTV signs page, which has several wordings.
Should I say my premises are alarmed if they are not?
No. Misleading signs can cause trouble and may reduce trust. Only display what is true.
What does "keep locked" use a blue disc for?
A blue disc means an instruction that must be followed.
Will a sign deter a thief?
Signs help show the area is monitored, but locks and alarms do the actual work.
