Unlike many other signs, our Notice All Activities Monitored By Video Camera Sign uses industry-leading 3M inks and not off-brand or other low-durability inkjet pigments that fade in a year or two.<br><br>USA’s Oldest Sign Manufacturer<br>Family owned since 1918, we take immense pride in our signage. Being one of the oldest certainly means we know this business in and out. Our South Dakota factory is the oldest manufacturer of metal signs in the USA.<br><br>Effortless Installation<br>These signs are attached to an 18 inch tall stake making the total length of the sign-stake assembly to 21.5 inches.
