This access provides a swift and dependable solution, diminishing the reliance on conventional keys or passwords. This advanced method reinforces security by utilising an individual's unique biometric traits, thereby significantly lowering the potential for unauthorised entry.

PIN Code

This approach eliminates the need for physical keys and provides a convenient and customisable way to control access to homes or buildings. Users enter their assigned PIN on a keypad or touch screen, and if the code matches the stored data, the lock grants access. PIN code access enhances security by allowing users to create and manage their individual codes, reducing the risk associated with lost or stolen keys.

Wi-Fi Connectivity

By connecting to a Wi-Fi network, users can use their smartphones or other devices to lock or unlock doors from anywhere with an internet connection. This technology enhances accessibility and security, allowing users to grant temporary access to guests or monitor entry remotely. Wi-Fi access simplifies door management and provides real-time notifications, offering a modern and flexible solution for controlling access to the property.

Be notified with push message on your smartphone in real-time when your family returns.

Unlock with Smartphone from Anywhere

Your smart phone is the door key. Simply and securely unlock the door with your smartphone from anywhere.

View Access Logs

One-Time Passcode (OTP)

Other Key Features

Random Security Code

Before you enter your password, you are guided to push two random numbers to prevent the password from being inferred based on the fingerprints on the frequently pushed numbers and from being seen by anyone nearby

No Harmful Substance

The door lock is manufactured in compliance with EU ROHS, which limits the contents of six harmful substances, including lead, cadmium and mercury. No harmful substance is contained in the product to be touched everyday by you and your family

Low Battery Notification

If the batteries are running low, the door lock informs you through a specific melody or keypad LED. You can easily replace the batteries without having to check the battery life

Emergency Power Supply

If you fail to replace the batteries before they are fully discharged, you can still open the door with a 9V battery on the instant battery charging terminal.
