As with any other electronic device, the common worrying factors of what happens if a sensor or the electronics fail or whether these devices are susceptible to extreme temperatures, might just creep into your mind when you are considering installing a fingerprint door lock at your home. This short article looks comprehensively at these issues and reviews the technology that has made door lock fingerprint technology a popular approach for access control.
First, the optical sensors – what if something goes wrong and the sensor fails to work? Does it imply that you will stay locked out of your house? It is very unlikely. These devices have been tested extensively and statistics show that false rejection rates are in fact minimal. The devices notify you when a battery needs to be replaced, so there is a very low chance of you ending up with a dead battery. Over and above that, most fingerprint door locks have in-built alternative mechanisms for unlocking in case the sensors do not do their job. They have over-ride features that offer alternative PIN based access or in case that fails, you could also use a mechanical key.
Modern fingerprint door locks are made to withstand extreme temperatures or even swings in temperature. Weather differences do not affect the working of a keyless fingerprint door lock. These digital door locks can work in temperatures as low as 15 ° F below freezing to as high as the mid hundreds.
As with any technology or security device, even a biometric fingerprint door lock may fail to work the intended way. For example, the sensor could be tricked into believing something that it should not. A fingerprint copied onto latex could be used to trick the sensor into believing that a programmed original fingerprint is being used when that may not be the case. As with any other security device that you use or the measures of safety that you adopt for your online banking passwords, it is therefore advisable to ensure safety measures on your part.
