Store cameras that tell staff before the queue does
Retail already runs cameras for loss prevention. The same streams can raise a firearm alert to the people on the floor.

Cameras
What is usually already there
Overhead cameras aimed at tills and aisles, often at long working distances.
Setup rates each one for the weapon classes it resolves at its working distance. A camera that resolves neither is not analysed and not billed.
Many stores
Sites roll up under one organization. Each keeps its own hours, roster, and rate.
Closed hours
Interior cameras alert only when the store should be empty. Exteriors stay live.
Camera reality
A till camera at 12m often resolves a rifle and not a handgun. Setup says which.
False alarm fines
Many municipalities fine repeat false alarms. Setup shows what applies at your address.
Response
Where an alert goes
Chains usually route to a district manager and a monitoring agent, never straight to dispatch.
The ladder is yours to configure. Nothing reaches an outside agency unless you set that up, and a review nobody actions escalates on its own timer rather than waiting.
