The ultimate in covert code entry
The Dark Window Keypad has a number of security features to aid the stealthy entry of secret codes.
- Shuffle mode, where keys are moved on each use.
- The Micro-Louvre display controls the viewing angle.
- Concealed RFID readers, for two factor authentication.
This keypad-Reader is both a Keypad Reader and a RFID (Radio Frequency Identification) proximity reader. The antibacterial micro-louvre display controls the horizontal viewing angle. At the same time, the vertical viewing angle is unaffected. All of this means that users both tall and short can use the keypad in complete privacy. Onlookers will only see a black screen.
Hiding the access control keypad when not in use increases security and leaves the display available for useful information and door status indications:
- Interlock
- Door Close Failure
- Connected Alarm Status
Shuffle Keypad
The keypad style can be adjusted and even made to randomise on each use so that “tell-tale” fingerprints do not leave clues to the access code digits. There are 3,628,800 possible key layouts.
The keypad reader connects to the controller with a simple 4 wire interface.
