Dual System Invisible Door Lock
No one can unlock your door lock by technical if you install a Deadbolt Lock and this invisible smart lock, you and your family can unlock it by the remote controller from outside. This invisible door lock installed inside of the door, and nothing changed on the outside of the door, therefore, you can’t see this extra lock from outside.
Dual System, Dual Power
We have a dual-system and power supply, a totally independent system! You can use the Standby system to unlock it if the main system failed. You can unlock it with the standby power when the main power runs out, even though we have a Smart Battery System.
Smart Battery System Design
When the battery power ≤ 30%, the lock will give a sound and light alarm to prompt you to change the battery. If you ignore this alarm and the battery is not changed, it can keep working for around 1 month. When the battery ≤ 10%, the lock will be automatically unlocked and cannot be locked. You’d better use the DURACELL battery, or this smart lock will work fail.
The external power supply is available, it ensures the lock works normally even though the main and standby batteries all run out.
No need to use Remote when you want to unlock it from inside, you only need to turn the Rotary Switch manually, which ensure you can unlock it when you are in a dangerous situation.
Antenna makes the remote control distance more than 30m in the empty place.
