👉 Foxproof is a type of security system that uses foxes to detect and warn humans. It was first introduced in the United States during World War II, but it has since become more popular as a home security solution. A foxproof system consists of an alarm bell that sounds when someone approaches the property or enters the house. The sound is generated by a small device called a "fox" which is typically made from a plastic or metal ring and is attached to the back of the alarm bell.
