Product role
Specify it as a paired lock display.
Quote TD-M45 only with a confirmed compatible TD lock. It is a room-side accessory, not an independent access-control terminal.
Compatibility boundary
Pair TD-M45 with one compatible TD smart lock on the same local network. It is not a universal smart-lock display, standalone door controller or smart-home gateway.
Visual two-way intercom
When the paired lock receives a visitor call, TD-M45 presents the live feed and supports a manually enabled two-way conversation.
Controlled remote unlock
The Unlock key is available only during an active live-view or intercom session; it is disabled outside those states.
Pairing and operating boundary
Confirm the lock, pairing and local network before quotation.
The display specification is only one part of the configuration. Confirm the lock model, pairing method and local network conditions before a set is supplied.
Confirm the compatible lock
Complete the lock and app setup first, then wake the lock display before starting the TD-M45 pairing procedure.
Pair the display to the lock
BLE 5.4 is used for pairing and provisioning. TD-M45 is intended for one-to-one pairing with a compatible lock.
Operate within the active session
Wi-Fi 6 on 2.4 GHz carries data transmission. Monitoring, calls and remote unlock operate within the defined active session.
Checks required before quotation.
Use one TD-M45 with one compatible lock on the same local network. Pairing multiple displays to one lock can cause abnormal doorbell calls. The TF slot is for firmware updates only and does not provide local video storage.
