Xiaomi Smart Door Lock 5C Cat Eye Edition Debuts with Advanced Home Security Features

Xiaomi has expanded its smart home product lineup with the Smart Door Lock 5C Cat Eye Edition, a connected door lock designed to combine convenient access with improved home monitoring. The device brings together a wide-angle camera, an indoor display, automatic locking and multiple ways to unlock the door.

The new model aims to make it easier for homeowners to identify visitors and monitor activity outside their homes without opening the door. It also offers remote access features and integration with Xiaomi’s smart home ecosystem.

Wide-Angle Camera Improves Doorstep Monitoring

One of the main features of the Xiaomi Smart Door Lock 5C Cat Eye Edition is its integrated camera, which provides a 160-degree field of view. This wide viewing angle helps users see more of the area around their entrance.

The camera supports intelligent detection features that can identify people passing by or remaining near the door. Depending on the configured settings, the lock can capture images, record activity and send notifications when movement is detected.

Another useful addition is camera obstruction detection. If someone attempts to cover the camera, the system can trigger an alert, helping homeowners identify potential interference with their security monitoring.

For nighttime use, the camera supports colour imaging in low-light conditions and switches to black-and-white night vision when the surroundings become completely dark.

The device also includes three days of rolling cloud storage, allowing users to review recent footage within the supported service.

Built-In Display Lets Users Check Visitors Indoors

The smart lock features a 3.5-inch display on the inside of the door. This screen allows residents to check who is standing outside without relying entirely on a smartphone.

When a visitor presses the doorbell, the indoor display can turn on automatically, making it easier to see the person at the entrance.

This feature could be particularly useful for families with children and older residents who may prefer checking visitors directly from inside their homes.

The lock also supports video intercom functionality, including a voice-changing option. Remote unlocking through the Mi Home app provides another way to manage visitors when the homeowner is away, subject to the device’s connectivity and configuration.

Eleven Ways to Unlock the Door

Flexibility is another major aspect of the Xiaomi Smart Door Lock 5C Cat Eye Edition. The device supports up to 11 unlocking methods, giving users several alternatives to a conventional key.

Supported access options include:

– AI-assisted fingerprint recognition
– Permanent passwords
– Temporary visitor passwords
– WeChat mini-program access
– Bluetooth unlocking through the Mi Home app
– Remote unlocking through the app
– A traditional mechanical key
– Compatible Xiaomi smartphones
– Supported Xiaomi smartwatches
– Compatible Xiaomi fitness bands
– NFC access cards

The availability of individual methods may depend on compatible devices, account configuration and regional support.

Offering multiple access methods can make daily entry more convenient for different household members. It also provides alternatives when users do not have a physical key readily available.

Automatic Locking Adds Everyday Convenience

The new smart lock features an automatic locking mechanism that engages when the door closes. Users do not need to lift the handle to activate the basic locking function.

Its internal clutch design and C-class lock cylinder are intended to improve resistance to certain forms of physical tampering.

Built-in sensors can also monitor unusual conditions. If the door is not properly closed or the lock detects an abnormal situation, it can issue an audible warning.

These features combine everyday convenience with additional monitoring, although no smart lock can guarantee complete protection against every form of forced entry.

Dual-Battery System Supports Longer Operation

Power management is another important part of the device’s design.

The Xiaomi Smart Door Lock 5C Cat Eye Edition uses a 5,000mAh rechargeable lithium-ion battery alongside four AA alkaline batteries.

According to the published specifications, the rechargeable battery can provide up to five months of operation, while the AA batteries are rated for up to six months under the manufacturer’s stated conditions.

The dual-power arrangement allows the lock to switch to the backup batteries when the main battery is depleted. This helps preserve basic unlocking functionality.

A USB Type-C emergency power port is also included, allowing users to connect an external power bank if temporary power is needed.

Actual battery life will depend on usage patterns, camera activity, connectivity and other operating conditions.

Xiaomi Smart Home Integration

The new door lock is designed to work within Xiaomi’s connected home ecosystem.

Compatible integrations can help users incorporate the lock into broader smart home routines. For example, supported devices and automation settings may allow certain actions to be triggered when users enter or leave their homes.

The ability to monitor visitors, receive alerts and manage access through connected devices could make the lock an appealing option for people who already use Xiaomi smart home products.

However, the availability of particular integrations and remote functions may vary depending on regional services, compatible equipment and software support.

Price and Availability

The Xiaomi Smart Door Lock 5C Cat Eye Edition was introduced in China with a listed price of 1,176 yuan. Following China’s consumer subsidy, its promotional price starts at 999.6 yuan.

These prices apply to the Chinese market and should not be treated as confirmed international retail prices.

As of the product announcement on October 9, 2026, an official global launch had not been confirmed. Buyers in other markets will need to wait for details regarding regional availability, pricing, warranty coverage and compatibility.

Final Thoughts

The Xiaomi Smart Door Lock 5C Cat Eye Edition combines several features that are becoming increasingly important in the smart home market. Its wide-angle camera, indoor display, automatic locking and multiple access methods are designed to make home entry more convenient while improving visibility around the front door.

The dual-battery system and emergency power option also address practical concerns associated with electronic locks.

For existing Xiaomi ecosystem users, the device could offer an interesting way to expand home automation and visitor monitoring. Its overall appeal, however, will depend on local availability, pricing, installation requirements and long-term reliability.

With connected security products becoming more sophisticated, smart door locks such as this one demonstrate how traditional home access systems are evolving into integrated digital security solutions.
