Emergency call boxes (ECBs) are a fixture in parking lots/garages and plaza areas as an integral component of a security plan for schools, airports, shopping centers and so on. The boxes are typically identified by emergency signs or flashing lights and most are activated by opening the door on the box and pushing a call button on the inside.
Cell phone cameras have made everyone who owns one a citizen journalist. Mobile journalists are quick to capture video of an incident and then just as quickly post it to social media. In some cases, this “video evidence” is used for social monitoring or even prosecutions. While cell phone cameras can be used to document anything at any time, the application is not the same as a video surveillance system.
Static electricity is more problematic when there is low humidity, no matter what the season. The issue is compounded as electronic devices today are smaller and more susceptible to electrostatic discharge. Granted, most electronics have ESD protection built in; but over time or from a constant barrage of these tiny lightning-like strikes, the protection becomes corrupted, resulting in a failure. Anytime air is warmed, this only reduces the humidity further, increasing the likelihood of a static discharge.
