The “Blind Pass” system aims at providing a technology enabling disabled individuals – especially blind people to open / close their home door(s) utilizing a simplistic remote control.
In the security system part the system consist of a unique fingerprint reading scanner which triggers the activation or the de-activation of the surveillance system based on the biometrical fingerprint information of the users.

Explication of the second block of my project :

The system is calibrated over 3 detection thresholds :

- Low risk (“Yellow”) – most likely triggered by family pets - Medium risk (“Orange”)

- High risk (“Red”) – an heavy disturbance is
being measured triggering immediate Alarm bell & demanding to the
Surveillance associate to intervene.
