Some technologies are a given: smoke detectors, fire alarms, carbon monoxide detectors, and, for many churches, a security system. Other devices—and newer technologies—might not be as common, but they can be just as valuable. Below are a few simple ways technology can make you safer.
Know thyself—and thine equipment. When you get new security devices or implement a new system, learn how to use it! It sounds like common sense, but it's imperative that churches take this seriously. A safety device (like an automated external defibrillator, for example) is worthless if not used properly.
Going keyless. Keyless-entry systems make monitoring access easier; after all, keys can be copied or lost. Over time, it's easy to forget which members have been given a copy (So if you don't go keyless, you should at least consider numbering keys and keeping a record of who has them).
