Online Digital Fingerprint Lock S550+

Fingerprint Scanner:

The fingerprint scanner of the S550+ fingerprint lock is an ergonomic biometric type, featuring an extremely low error rate of 0.0001 and a scanning speed of 0.15 seconds. It is considered one of the most effective biometric scanners currently available on the global market.

Private Mode:

One of the most practical features of the S550+ smart fingerprint lock is the ability to activate Private Mode. This mode is enabled from inside the unit, and once activated, other users will not be able to unlock the door from outside—even if they have a registered fingerprint, passcode, card, or mobile access. The lock will notify them that Private Mode has been activated internally, and the handle will block any attempt to enter a passcode or use a card from the outside. However, administrators will still have the ability to unlock the door.

Fake PIN Code Feature:

The Fake PIN Code system in the S550+ digital handle is designed to prevent hacking and password exposure. The ability to identify the correct passcode within a string of random digits is one of the unique and sophisticated algorithms used in the design of these products.

This means that when a user wishes to enter their actual passcode, they can insert any number of random digits before or after the real code if others are present. This feature significantly enhances user security and contributes to a greater sense of confidence and satisfaction among consumers.

System Management:

The S550+ fingerprint digital lock allows for the registration of up to 9 administrators (Admins). Each administrator can independently access the management system and apply their desired settings. The minimum number of Admins is one, and the maximum is nine.

One of the key differences of this handle lies in the admin access method, where administrators can enter the settings menu using their fingerprint—a feature not available in Korean products currently sold in the world market.

Access Log System:

Monitoring entry and exit is one of the most valuable features of this product line. The ability to track user activity, including names, exact date, time, and minute of access, as well as the method of entry (password, card, or mobile), significantly sets this product apart from competitors.

One of the ways to access these logs is directly through the handle’s menu. An Admin can enter the handle menu, navigate to the access log section, and view the last 1,000 access records. Additionally, the Admin can filter and view logs for a specific day.

Intercom Compatibility:

For residential building lobby entrances, this fingerprint lock supports intercom access. By adding the ALOCK-specific intercom module, users can wirelessly unlock the door via both video and standard intercom systems, without the need for additional wiring.

User Deletion Capability:

Most digital lock products available in the world allow user registration, but when it comes to removing a specific user, they typically require a full system reset. In contrast, this handle offers a unique feature—the ability to delete a specific user by their assigned ID. The administrator can access the settings and remove the desired user directly. One of the most enjoyable features is the ability to delete a user remotely from anywhere in the world using a mobile phone. This functionality makes it stand out globally compared to other brands on the market.

Remote Unlocking Capability:

While most products offer remote control functionality with a limited Bluetooth range of 2 to 10 meters, this handle, equipped with Zigbee wireless technology and the specialized Wishome app, allows users to unlock the door from anywhere in the world via mobile or computer. The software is compatible with both Android and iOS platforms.

Passage Mode (Free Access Mode):

When you’re hosting guests or expecting frequent access—such as clients entering your office—constantly entering a passcode or using a card can become tiring and inconvenient. It also significantly increases battery consumption. This product, however, is equipped with Passage Mode, allowing users to unlock the door without the need for a code, card, or fingerprint. Once the event or business hours are over, you can simply deactivate the mode and restore the handle to its original secured state—preventing further access without valid credentials.

What makes this feature even more convenient is that the administrator can activate or deactivate Passage Mode remotely via mobile phone from anywhere in the world.

Two-Factor Authentication (2FA):

When you need precise control over access and enhanced security for sensitive locations, ALOCK naturally becomes the brand of choice—because all ALOCK products come equipped with this feature. However, in the S550+ model, this capability stands out even more due to its ability to be activated or deactivated instantly via mobile from anywhere in the world.

When this mode is enabled, unlocking the door requires two authentication methods from the combinations below:

Fingerprint + Passcode

Fingerprint + Card

Passcode + Card

This added layer of security is one of the key reasons behind the growing popularity of the S550+ model.

Temporary Passwords (Temp Passwords):

One of the most popular features of ALOCK smart handles is the ability to generate temporary one-time or limited-use passwords. Using the Wishome app, the admin can define a time-based one-time password via mobile. For example, a password such as 123456 can be set to be valid for one hour, one day, one week, one month, one year, or even 3 months, 10 days, and 25 minutes. However, the user will only be able to use this code once, and it will automatically expire after use or upon reaching its expiration time.

Alternatively, the admin can define a reusable password valid for unlimited usage within a specific hourly, daily, or monthly time frame, or even for specific calendar dates.

Unlocking via Mobile Facial Recognition:

In the world digital lock market, you will rarely find a brand or model that allows unlocking via a registered fingerprint or facial recognition directly from your mobile phone. This feature is standard across all ALOCK online smart locks, enabling users to unlock their doors using Face ID, Pattern, or the fingerprint sensor on their smartphone—without the need to touch the lock itself.

Handle Status Monitoring:

When using an online smart lock, it’s essential to know the real-time status of your lock. You can check:

The battery level of the device

Whether the lock is online or offline

The last time the data was synced between the lock and your mobile device

This brings convenience and a sense of security, which has been thoughtfully integrated into the design of ALOCK products.

Multi-Lock Control Capability:

One of the most convenient and impressive features of ALOCK online products is the ability to control multiple smart locks using a single mobile device.

This means you can install ALOCK online locks on your home, office, villa, or any other location, and manage them all from one mobile phone as the Admin. You can monitor access, receive real-time reports, and control entries seamlessly from anywhere.

User Management: Add & Remove Users

A common concern among users of digital locks and smart handles is the need to add or remove users, which often requires being physically present at the lock.

However, ALOCK’s designers have eliminated this limitation in their online lock series by allowing real-time user management via mobile.

The Admin can easily add, delete, or modify user access remotely. For example, if a user named Sara previously accessed the door via fingerprint, the Admin can delete her fingerprint remotely and assign a new passcode (e.g., 121314) instead. From that point forward, Sara will only be able to open the door using the new passcode.

Hijack Mode:

A unique and critical safety feature of ALOCK online products is the Hijack System, designed for situations involving coercion or physical threats.

If someone forces you to open the door under duress, you can use a pre-set Hijack code to unlock the door. The door will open as usual, but simultaneously, a silent alert will be sent to all users connected to the lock—excluding the person who used the Hijack code, ensuring their safety is not compromised.

Device Power Supply:

This product operates solely with 4 standard 1.5V AA batteries. With regular non-branded AA batteries, the average battery life is approximately 6 months, while using alkaline AA batteries can extend this duration to 1 year. Additionally, the lock is designed with space for 4 extra AA batteries, providing extended battery life and a more convenient experience for users.

Emergency Power Supply:

In the event of low battery, in addition to viewing the battery percentage on the device display and on your mobile screen, and receiving low battery notifications on your phone, you can supply power to the device externally using a 9V battery. Once powered, you can unlock the device using a valid passcode or card, and then replace the internal batteries from inside.

Emergency Key:

One of the final security features of the 117NP+ handle is the anti-acid and anti-theft mechanical key. This feature is designed for situations where the handle completely shuts down after multiple low battery warnings and a 9V battery is not available. It is highly recommended to store the mechanical keys outside of the unit to ensure easy access when needed.

Moisture Resistance:

The exterior and interior panels of the handle are made from compressed aluminum. The electronic board, designed with Japanese-made components, is rated IP65 and resistant to moisture. This feature makes the product ideal for humid and coastal regions in the world. Compared to other brands on the global market, it offers exceptional quality.

Comparison with Other Brands:

Most leading companies and brands selling digital locks in the world primarily focus on sales-driven approaches. However, ALOCK emphasizes a service-oriented model, which has significantly increased customer trust in the high quality, reliable after-sales support, and valid warranty of its products. This is one of the key differences between ALOCK and similar products in the world market.

Another distinguishing feature of the S550+ fingerprint lock is its user capacity. While most brands support between 5 to 25 offline users, this model can store up to 300 offline users.

Another advantage is battery efficiency. All ALOCK products are rated A+++ in energy saving, thanks to their Japanese components and extremely low static and dynamic current consumption, resulting in significantly extended battery life.

Additionally, ALOCK stands out in terms of compatibility with various door types. Most brands on the market cannot connect to multi-lock systems and only function with their own proprietary locks. In contrast, ALOCK products are compatible with all types of multi-lock and vault systems, including fireproof and security doors, and can simultaneously control both upper and lower locks with the smart lock system.

Another critical point of differentiation lies in the lock body material. Many locks available in the world are made from lead-based materials to ensure smoother operation. In contrast, ALOCK lock bodies are constructed from steel, offering resistance to crowbars and even bullets up to 1,112 kg of force. Additionally, these steel lock bodies are acid-resistant, ensuring enhanced security and durability.

Comparison with Other ALOCK Models:

Comparison with Fingerprint Lock Model 116NF+:

There are several key differences between the S550+ and 116NF+ models. One notable distinction lies in the durability and weight of the handle. The S550+ handle is made of compressed aluminum and weighs 4 kg, while the 116NF+ handle is made of zinc alloy and weighs nearly 8 kg. As a result, the total weight of the 116NF+ is significantly higher than that of the S550+.

The S550+ handle body and structure can withstand up to 1200 Newtons of direct force, whereas the 116NF+ can endure more than 2500 Newtons, highlighting a clear difference in structural strength between the two models.

Another significant difference is the presence of a mechanical gearbox. The 116NF+ is essentially the only handle on the global market equipped with a Facilitator-type mechanical gearbox, which contributes to its heavier weight, higher price, increased durability, and a design reminiscent of American machinery.

Comparison with Smart Fingerprint Lock Model N120+:

Aside from differences in design and color, the S550+ and N120+ differ in several aspects:

The N120+ is equipped with a child lock, whereas the S550+ is not.

The N120+ features gold plating, similar to the 116NF+.

The N120+ allows users to set one-time passcodes directly on the handle (offline), a feature not available on the S550+.

Comparison with Fingerprint Digital Lock Model N118F:

There are only two differences between these two models:

The N118F supports offline time-limited one-time passcodes directly on the handle.

In the N118F, the admin cannot unlock the night lock from outside, unlike in other models.
