Why Do Security Devices Fail in Heat and Vibration-and How Do You Design for Reliability?
Security systems should be functioning at the time you need them the most. However, the point is that in this case, they tend to work in environments that would make the majority of electronics give up. Imagine a surveillance camera on a desert highway, where it is 120°F and the sun is blaring. Or a movement detector in a factory store, which is shook by machinery all the time. These aren't edge cases. They are daily facts to security equipment.
