These video surveillance signs are perfect for those that want to let others know that there might be some video activity on the premises. They stick almost anywhere you put them, they stay put on wood and vinyl as well as brick. They come ten to a pack so you can post them all around your property and even share some with the neighbors. Makes the property look like it is under twenty four hour surveillance. Pretty good idea and works really well. to deter people from your place. They never know if you have cameras around or not.
