Top-tier data protection

To identify users quickly and securely, KeyPad Plus features the DESFire® technology. It is the best-in-class contactless solution to identify a user by card or key fob.

DESFire® is based on the ISO 14443 international standard and combines comprehensive 128-bit encryption and copy protection. This technology is also used in transportation systems of European capitals and access systems at NASA.

Microchip with smart capabilities

From the user perspective, contactless access works simply. To disarm the system, all you need is to present a card or a key fob to the keypad. But there is an impressive technology behind this simplicity. Pass cards and Tag key fobs are equipped with DESFire® chips. We compared them to the chips used in most access systems around the world.

Outstanding autonomy

The all-new KeyPad Plus firmware gets the most out of the pre-installed batteries. Even with daily use of the contactless identification function, the keypad will work for 3.5 years without replacing batteries. And with the card and key fob reader disabled, the battery life reaches 4.5 years. KeyPad Plus will warn a monitoring station and users in advance about the need to replace the batteries.

Remote access control

Set up personal passcodes to know who and when disarmed the system: a username is displayed in the notification and in the event log. Pass or Tag can also be assigned to a specific user with defined permissions to control security of specific groups or the entire site. Ajax app allows you to manage access permissions in real time. You can limit, extend, or instantly block access.

Adding users. Fast and easy.

Ajax systems support up to 200 Tags or Passes2. When adding them, you do not need to create Ajax accounts for new users, you just need to name a device and define access permissions. This makes it easier to delegate access to the system control to temporary employees or incoming staff.

Multilevel anti-sabotage system


Users and a security company receive a notification when someone removes the keypad from the mount

Blocking when guessing a passcode

Three wrong passcodes entered in a row block the keypad and trigger an alarm


If there is an attempt to use an invalid card or key fob, the system activates an alarm

Polling intervals

The system detects the communication loss with the keypad in less than a minute3

Silent alarm transmission to a monitoring station

If attackers force to disarm the system
Duress code allows you to simulate disarming via KeyPad Plus. The user is not disclosed by sirens, the app and the keypad indication, but the alarm signal is instantly transmitted to a central monitoring station4.

Guaranteed alarm delivery

We have developed the Jeweller radio protocol to ensure the uninterrupted operation of all system devices. The radio protocol uses time frames to synchronize communication of connected devices, authentication to eliminate forgery, and encryption to protect against hacking.
  • Two-way communication at a distance of up to 1,700 meters
  • 5 ReX radio signal range extenders in a system
  • Adjustable ping interval from

Smart security management console

Use scenarios to shift your daily routine to Ajax. When arming, the system turns off the lights, the water and electrical appliances, closes the roller shutters, all in one touch on KeyPad Plus.

Effortless installation

KeyPad Plus is connected and configured in Ajax apps. No need to disassemble the enclosure or install batteries. Adding to the system is done via simply scanning a QR code. An installation engineer only needs to test the device, add cards and set up access permissions.
