What Spec Actually Matters When Buying Smart Lockers for a School?

Direct Answer

A school locker spec comes down to four inputs: peak students on site, the largest bag you store, how each student proves who they are, and who clears a compartment at year end. Most schools land on a Password Locker bank on a 300 mm module, plus a Face Recognition Locker at the wet-weather entrance.

Where School Locker Specs Go Wrong

• One compartment size for too many things. A PE kit, a laptop, and a cello do not fit the same box. Standard and tall modules side by side cost less than a wall of half-usable boxes.
• Corridors are the real constraint. Usable wall can be 4 m, and a 24-door bank does not fit there. Narrowing doors until it does produces bent frames and jammed doors.
• Codes and leavers. A 6-digit code a whole class knows is a shared code, and a compartment stays locked from July into September. Policy matters more than the keypad.
• Fees decided late. Charging students for a bank before the module and the wall length are fixed is how a scheme gets value-engineered after the order.

Sizing the Bank: A Calculation You Can Re-run

Start from the peak count — a school may roll 900 students and run 1,150 on site on a wet Wednesday — then add staff compartments and 10% spare.

compartments = peak students + staff + 10% spare

That spare is what schools cut and regret: lockers outlive the timetable that justified them. Split by type — say 70% standard, 30% tall — then count doors, not students.

The arithmetic uses a 300 mm door module; confirm it against the drawing before ordering.

bank run = doors × 300 mm + 200 mm frame allowance

floor used = bank run × (450 mm depth + 1,100 mm working aisle)

12 doors: 12 × 300 = 3,600 mm, + 200 = 3,800 mm = 3.8 m run

18 doors: 18 × 300 = 5,400 mm, + 200 = 5,600 mm = 5.6 m run

24 doors: 24 × 300 = 7,200 mm, + 200 = 7,400 mm = 7.4 m run

Check: 300 × 24 = 7,200, + 200 = 7,400 mm = 7.4 m. Corridor in front: 450 + 1,100 = 1,550 mm. Where the wall is short, set two smaller banks rather than shrinking doors.

Choosing the Identification Method

| Method | Locker type | Fits a school when | The catch | |---|---|---|---| | 6-digit code | Password Locker — cost-effective | Shared corridors, tight budgets | A known code is a shared code; rotate it | | Face match in 0.3s | Face Recognition Locker — wet-hand friendly | Entrance, wet weather, sports arrivals | Mounting height and lighting decide readability | | Scan and print | Barcode/QR Locker, auto ticket dispenser | Kit issue, lost property | Claim slip is paper; the audit trail is the record behind it | | Live-body match | Palm Vein Locker — banks, courts, high-end clubs | Exam-hall secure stores | Enrolment per user, higher unit cost | | Pay-as-you-go | QR Pay Locker — WeChat / Alipay, hourly | Students buying kit on site | Billing logic, not a bag register | | Sensors | AI Security Locker — fire, fight alerts, intrusion | Unattended kit and exam stores | Needs power, network, a staffed alarm path |

Common Challenges

• Keep the terms apart. The claim slip is the ticket the Barcode/QR Locker prints when an item goes out; the audit trail is the electronic record of opens and assignments. One is paper, one is data — tender documents that swap them cause arguments at handover.
• IP54 is not a fire rating. Fire detection, fight alerts, and intrusion detection from an AI Security Locker are signals for the building's fire strategy, not a substitute for it. Store no flammables or pressurised cylinders.
• Integrations are scoped work. WhizSmart provides hardware and software custom development services, so attendance or access-control integration is available — specify it with the order, not after go-live.
• Lead time. Standard units (ABS plastic lockers) about 30 days; custom builds about 60 days for the cabinets, about 90 days including software development. Minimum one unit standard, ten units for a custom build — that ten counts units, not days.

What Changes Next

The first shift is fallback by design: face recognition as the fast path, with a keypad path behind it. A student locked out at 07:50 with an exam at 09:00 costs a school more than the redundancy costs to build.

The second is the locker as a records source: a scan-and-print bay prints a claim slip at issue, and paired with the audit trail it becomes the base for kit return at year end.

FAQ

What does a 12-door bank take up? On a 300 mm module: 3,600 + 200 = 3,800 mm, a 3.8 m run, plus 1.55 m of corridor. An 18-door bank is 5.6 m; a 24-door bank is 7.4 m.

Password or face recognition? Codes suit shared corridors and tight budgets; face recognition suits a wet-weather entrance. Both is common — codes on corridor banks, face at the gate.

Certifications and warranty? WhizSmart holds ISO 9001, CE, FCC, and IP54, and works from its own source factory in Fuzhou, Fujian, founded in 2014, with a portfolio of patented technologies. Warranty is a 1-year warranty on the whole unit plus a 1-year warranty on core components, with lifetime technical support and 1-on-1 remote training.

WhizSmart has built smart lockers in Fuzhou, Fujian since 2014, as a factory with its own production rather than a trading desk. Send the peak headcount, the corridor length, and the bag sizes — the layout follows from those three.
