Good luck with your favorite purchasesFeatures: * Invisible smart door lock without holes: Single-sided installation without holes indoors, no installation traces outdoors. Swipe the card outdoors, and the lock can be unlocked in 0.5 seconds. * Automatic unlocking at low power: When there is power, the lock is unlocked normally, and the voltage is lower than 4.6V to unlock automatically. When the power is low, the lock tongue automatically retracts and unlocks automatically. When the power is low, the voice system reminds you to replace the battery, and you are no longer afraid of not being able to open the door due to lack of power. * Two unlocking methods: The smart door lock supports APP unlocking and IC card unlocking, smart phone APP unlocking, and supports real-time viewing of unlocking records. You can choose the way you like to unlock. * Magnetic door lock: When closing the door, the lock tongue senses the magnetic stone and automatically locks. * Wide range of applications: Smart door locks are widely used in indoor non-metal doors such as homes and offices, with a door thickness not exceeding 60mm. Note：The difference between having a gateway and not having one is just the distance issue. With a gateway connected to the internet, you can unlock from a remote location. If only connected to the app without a gateway, you can remotely unlock within the Bluetooth connection range, which is generally about 8 meters.
