Contactless control without reliability compromises 🕹

KeyPad Plus is a combination of design, advanced encryption technology and elaborated user experience for the most straightforward and protected security management. Arm and disarm Ajax, activate Night Mode and manage specific groups with a Pass card or Tag key fob (Cards and key fobs are sold separately).

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.

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 Passes (Depending on the hub model: Hub 2 — up to 50 users, Hub Plus — up to 99, Hub 2 Plus — up to 200). 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.

Installation and set up 👨‍🔧

Ready to operate straight out the box: the battery is already installed, therefore there is no need to disassemble the keypad plus. With one click, it can be connected to the hub in the mobile application. It can be mounted on the SmartBracket in just a few minutes.
