Security Alarms

What is a security alarm? A security product that sounds at a high volume for a certain period of time when an installed door or window opens. It is often attached to entrance doors and window glass, and is often used in general households. There are types that detect intrusion with sensors and types that detect impact and breakage of glass, etc. You need to select the product depending on the installation location. Most products use coin-type batteries or AAA batteries. Many of them do not take up space because they are compact.
