Xiaomi MIJIA OJJ X1 Smart Door Lock With Intelligent Fingerprint

The smart OJJ X1 lock features a smooth integration of a fingerprint scanner into the handle and a modern ergonomic design. The scanner is located in a convenient place for the thumb, and the design combines several concentric rings – from the scanner to the handle and from the handle to its base.

Would you like to download a separate application for each smart device? I don’t think so. That’s why the MiHome platform allows you to connect a variety of smart devices to one system. With just one app, you can control your smart OJJ X1 lock, air purifier and lighting, and you can collaborate and automatically turn them on. In addition, when a lock is detected, you can set the Loock CatY smart camera to automatically turn on to record and send video.

The OJJ X1 Smart Lock combines fingerprint recognition, image recognition, self-learning algorithms and other advanced technologies to make prints more accurate. In simple terms, the more the OJJ X1 lock is used, the faster it recognizes fingerprints.

What to do when friends or relatives come to visit and there is no one at home to meet them? There is no need to rush home with your head in the air – the smart OJJ X1 allows you to create a disposable code and send it via SMS or messenger. Besides, the application allows you to create codes with an action schedule.

The OJJ X1 uses a strong horizontal larvae, which corresponds to level C in terms of burglary resistance, and such locks are used in financial institutions due to their high security (Level C above level B and A). In addition, the larva has been certified for burglary resistance by the State Testing Centre of the Ministry of Public Security.

If the lock is detected as a failure, five incorrect code entry attempts or 15 unauthorized fingerprints are recognized, the OJJ X1 will launch a smart alert system that will not only send a notification to the local security office, but will also alert you with a notification in the MiHome app.

To prevent fingerprint or password data from falling into the hands of intruders, the OJJ X1 uses multi-level encryption technology, the heart of which is a special security chip MiHome, providing the highest level of data protection. The chip encrypts not only the data inside the lock, but also all communications with the smartphone.

Some modern intruders use special Tesla coils to open electronic locks, but the OJJ X1 design is fully protected from any electromagnetic interference and radiation. All products are still factory tested for electromagnetic compatibility to ensure they meet the highest quality and safety standards. The smart OJJ X1 lock protects your home from threats at any level.

The design of the OJJ X1 lock uses a double German bearing, which provides more than 10 years of handle life even with 30 opening cycles every day. The metal plate in the keyboard area is shock-resistant and all internal cables and external connectors are made to the highest quality standards.

The smart OJJ X1 lock was created using only the best practices in fingerprinting technology, power supply and more. The highest quality is confirmed by many patents in various fields.

The OJJ X1 lock has been successfully tested for 96 hours in salt spray, so it can be used even in coastal areas. In addition, the lock works steadily at temperatures ranging from -25 ° C to +55 ° C.
