The person who left last month may still be able to walk in. Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - Single zone: alarms but doesn't say where. - Multi-zone (for example 6, 18 or 33): lights show where on the body. - Outdoor use needs a weather-rated model or shelter. Quick answer Walk-through detectors differ mainly in how precisely they locate metal (the number of zones) and in extra features: weather protection for outdoor use, people counting, and on some models body-temperature screening. More zones help guards find items faster, which speeds up busy entrances.
