Review on Surveillance Property Trespassing Protected Resistant by Justin Olson

These signs are eye catching and hard to miss. I like that they are made for outdoor use in the elements as they are metal and painted. They have a smooth surface, there are also no convex letters. I like that they are drilled around the edges and weigh next to nothing. They come without screws or stands, so they must be purchased separately if required. Due to their size (slightly smaller than the lid of a shoebox) they are best wall mounted in my opinion. It seems to me that the maximum reading distance for these signs is 20-30, so it's best to use them in places where people can get close to them.
