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).
Do be alarmed. Security systems act as a deterrent; they also help law enforcement catch would-be criminals and vandals. Various types of security systems exist—with some being more beneficial than others—but the most important thing is to have something—especially if your church has had any security issues in the past.
Just checking (in and out). Safety procedures tend to become an even higher priority when they involve kids. Parents want to know that it's safe to bring their kids to church—and safe to leave them in the hands of others during church. And that's why an efficient check-in/check-out procedure is imperative.
Diligence is your best defense. Church is a place where everyone should feel welcome. Treating every visitor as a potential threat would be a terrible practice. Church leaders should, however, be aware of potential threats—on Sunday mornings or any other time. Technology can make a facility safer, but even the best new technologies (security cameras, metal detectors, AEDs) often require the attention and implementation of trained individuals.
