How Is the Teller Line Engineered for Security and Workflow?
By Jeremy Mills, CEO & Founder, Apex Grid Engineering — USAF Veteran. · Updated 2026-09-15
Teller lines are engineered as repeatable secure workstations: millwork coordinated with power/data for every device, ballistic glazing and undercounter protection, task lighting for cash visibility, and queuing laid out so waiting customers cannot observe transactions.

Millwork, glazing, and protection
The teller line millwork is detailed around the security requirements: transaction openings sized for the specified glazing, undercounter ballistic panels integrated into the counter construction, and anchored positions for every cash-handling device. Counter heights serve both standing tellers and the accessible lowered section the code requires. Materials are chosen for durability — the line takes a beating — and the details allow panel and device replacement without rebuilding the counter. I review the millwork shop drawings against the security and electrical requirements before fabrication, because the shop is the last cheap place to catch a conflict.
Power, data, lighting, and air
Each station's electrical and data rough-in is placed from the device list with spares, on dedicated circuits where the bank's standard requires. Lighting layers general illumination with station task lights for cash visibility and screen comfort. The HVAC serves the line quietly — low background noise so tellers hear customers, draft-free air so nobody works in a cold spot. Duress alarm wiring and CCTV rough-in go in with the rest, because the line's security systems are part of the workstation, not an overlay.
Teller line design checklist
A teller line design is complete when it clears this checklist. The line is where the bank earns its keep — every detail serves speed, accuracy, and safety. • Millwork detailed with specified glazing, undercounter protection, and anchored cash equipment • Power and data rough-in for every device at every station, dimensioned before millwork fabrication • Layered lighting for cash visibility without screen glare, supporting camera views • Queuing laid out with privacy setbacks so waiting customers cannot observe transactions • Quiet draft-free HVAC, duress alarms at each station, and an accessible lowered section
