TM-Ai20
The TM-Ai20 is a face access terminal and the family head with QR support: residents walk in on their face, visitors tap their phone against the same glass. The gate design is one device, and the crowd splits itself.

Line values per catalog are family-class figures. TM-Ai20-specific figures are stated in the datasheet extract and confirmed by the FAE on request. Exact capacities and options by model vary — the sales team confirms the per-SKU matrix within 48h.
Nobody registers a doorbell for the courier.
Visitor handling is a state machine that usually ends at a shouting intercom. With QR support, the gate gives the visitor an independent action: the invited code from the host, the camera doing its own job.
- Code turns into an event — QR pulses logged, so the visitor, the host, and the record agree.
- Face and code parallel — your staff keeps their face inside; invited read their pass. No kiosk machine on top of the door.
- Host-issued access — the invite config is software-side, so a change of policy doesn't involve a schematic.
TM-Ai20 FAQs
Yes — codes are software issued and revoked in the same view punches live; the QR lane reads whatever the host config publishes at the gate.
Printed and display codes of the pass class are both read (config); glossy small print is a formatting nuance the FAE team checks against your template.
No — lanes are independent; the 0.3 s face class stands, and the QR lane reads in parallel with the same events ledger.
