Why does AP501 not use biometric functions such as fingerprint or voice recognition?
There are fine products that use biometric technologies (mostly for commercial indoor use and not for residential doors exposed to the weather, however) but we decided against such technologies so that we did not have to compromise our security. For instance, fingerprint recognition would require a scanner, whether with an optical or silicon sensor, that can easily be vandalized. The voice recognition technology would require openings to accommodate its microphone that can also be easily vandalized. Plus, those digital door locks with fingerprint or voice recognition we tested showed unacceptable levels of error rates in recognizing the fingerprint or voice input.
