Home security signs are available that warn trespassers or passers-by that your home is protected by security surveillance of some kind. Companies who sell home security equipment often provide signs, window decals and stickers that you can place around your property as a deterrent. If you are interested in posting a sign to inform others that you are using a security system of some kind, you can purchase one separately. Swann sells a Security Yard Stake Warning Sign that can be mounted on the stake, on a window or on a fence, whichever you may prefer. Additional warning stickers are included with the sign. The sign is 6 inches in diameter and the sign plus stickers cost $12.40 to buy.
You can buy "Exit" signs much like the ones you see at movie theaters or in large buildings that have video surveillance cameras embedded. These embedded video surveillance cameras may also be hidden cameras, cameras that are there but that cannot be detected from the outside of the sign.
If you have a watch dog you can buy security signs that warn of this. For instance, for $8.99 you can get a sign that reads, "Protected By American Bulldog Home Security System 24 - Hour Monitoring," if it is a bulldog that you have. On EBay you can purchase a dog warning sign that reads "Caution Area Patrolled By 'Pit Bull'" or other dog of your choice for $9.95. Petco sells a security dog sign that reads "Warning Security Dog" for only $2.97 that you can post in your yard. It is made of metal.
