6, 18 or 33 Zones? Choosing a Walk-Through Metal Detector for Your Miami Venue
Zones decide how fast your line moves and how often guards have to re-check people. Here is how to pick the right walk-through metal detector for a Miami school, church, club or event.
When a venue manager calls us asking for a walk-through metal detector, the first question we ask back is simple: what happens after the alarm goes off? The answer tells you how many detection zones you actually need.
What a "zone" really is
A walk-through detector is two panels with transmitting and receiving coils. A multi-zone unit splits those panels into separate detection areas stacked from head to ankle. When someone sets off the alarm, the LED bars light up at the height where the metal is, so your staff knows to check the left pocket instead of patting down the whole person.
6 zones: basic screening
Good for smaller entrances with light traffic, where the goal is deterrence and you have time for a full secondary check with a handheld wand. Fewer zones means less precise location, so every alarm takes a little longer to clear.
18 zones: the sweet spot for most venues
Schools, churches and synagogues, nightclubs, quinceañera halls and concert entrances in South Florida usually land here. Eighteen zones give guards a clear height and side for each alarm, which keeps the line moving at doors where hundreds of people arrive in the same 30 minutes. Our MegaDetector 18-zone gates also count people as they pass, which helps with occupancy limits.
33 zones: high-security checkpoints
Courthouses, government buildings, stadium gates and any site where secondary screening is expensive benefit from 33 zones. The finer the map, the fewer full pat-downs you run.
Indoor, outdoor and Miami weather
If the gate will sit under an overhang or on a pool deck, look for a weatherproof (IP-rated) unit and a cordless option so you are not running extension cords across a wet walkway. Afternoon storms are a fact of life here; plan the placement before event day.
Don't forget the rest of the lane
- A handheld wand for secondary checks
- A divest table for keys, phones and bags
- Clear signage and one trained person per gate
Rent first, buy when it is permanent
If you only screen for a few events a year, renting is usually smarter. If security is now part of your daily routine, buying pays for itself. See our Florida rental service, or call (786) 491-3611 and we will help you pick the right gate. You are also welcome to come walk through one at our Doral warehouse.
