How Smart Locks can save lives and why wireless power helps15 August 2018
Smart locks offer key-less entry to homes and offices. Instead of a key, the lock can respond to an app, a keypad, a fingerprint and so forth.
One example where smart locks are very helpful is to assist with emergency entry. For instance, an elderly person might subscribe to an emergency service such as LifeAlert. When urgent assistance, the emergency service rushes to the location but then has to open the door. Given the emergency, the subscriber might not be able to open the door. The emergency service has to break down the door, but this takes time in a situation where every minute could be the difference between life and death. Once the situation is resolved, the door would need to be repaired, usually at a high cost.
In contrast, if a smart lock was in place and the emergency service had the code, authorized entry is quick and easy.
Smart locks, however, run on batteries and these batteries need to be replaced. Users might forget to replace the batteries and they would be locked out of their homes.
One could theoretically run an electrical cable to the door and the smart lock, but this requires professional (and often expensive) installation.
Wireless charging allows installing smart locks without the fuss of extra wiring. Additionally, smart lock vendors could add extra functionality now that there are no battery constraints. For instance, a short video of an approaching person can be captured and uploaded to the cloud. Face recognition is another important feature that drains the battery.
