TTLock system in practice

On the outside of the door is the WK2 keypad – you enter the code, and the door opens. Instead of searching for keys, you can enter your assigned PIN in one move, opening the door in person or granting remote access.

The user can also use the R1 remote control , which allows the door to be opened without having to approach it – e.g. from a car, reception desk or apartment upstairs.

On the inside of the door there is an RX2052 lock , which can be opened manually with a knob, IC card or via the app.

To make the system work even faster and fully remotely, you can supplement it with the TTLock Wi-Fi gateway , which enables instant data synchronization between the application and devices – without the need for physical proximity.

All system components – lock, keypad, remote control and Wi-Fi gateway – are available in our range and can be freely combined to create a configuration tailored to your needs.

You can also expand the set with devices compatible with the TTLock app, such as wireless keypads, door locks, electronic padlocks, cabinet locks, and door inserts.
