Xesar release 3.1 Even easier. Even better. More benefit for you
[Translate to International:] Release 3.1
Here are the most important improvements in detail

The new Version 3.1 software update for Xesar makes the system even easier and even better. The new Installation Manager and the ability to perform maintenance tasks wirelessly are the highlights of the new release.

[Translate to International:] Installationsmanager
New Installation Manager:

The new Installation Manager for PC installations guides the user through the software installation in simple steps. All necessary system settings are checked and solutions are suggested if necessary. Now, even users with little training can complete the PC installation in the shortest possible time.

Wireless maintenance

There is no longer any need for a cable connection between the component and the tablet to perform maintenance tasks. Maintenance is carried out via encrypted wireless connection.
Bluetooth on/off card
In construction mode, the wireless transmitter on the component can be switched on and off as required using the Bluetooth on/off card or key tag.

[Translate to International:] Sichere Bluetooth Verbindung
Secure Bluetooth wireless connection

The new Bluetooth wireless connection is secure against hackers. All data communication channels in the Xesar access system are encrypted regardless of the transmission type (LAN/Wifi/BLE/USB/RS485/...). If, for example, a vulnerability in the Bluetooth encryption is known, this is irrelevant for Xesar because any data exchange in the access system is additionally encrypted.

[Translate to International:] Mehrkomponenten-Konfiguration
Multiple component configuration

The tablet connects to the surrounding BLE components. Then all necessary maintenance tasks can be started at once. While the maintenance tasks are being performed, you have time for other things. If you run out of time, the maintenance can also be cancelled prematurely and resumed later.

[Translate to International:] Neue Bedienoberfläche
New user interface

The user interface of the maintenance app has been completely revised. The appearance has been relaunched and user navigation improved. The new maintenance app can operate BLE components as well as those that continue to be operated with the cable.

Battery management optimised

The Xesar software now clearly displays the battery status, giving the maintenance technician clear guidance. A “Battery empty” status is automatically placed at the top so that it cannot be overlooked. Battery replacement is described on the tablet in a step-by-step guide.

Xesar cylinders

Xesar cylinders

Xesar cylinders are suitable for doors in indoor as well as outdoor areas. Thanks to cutting-edge security technology, the components are protected against all common tampering methods. Their modular design allows the length to be quickly adapted on site. As hybrid cylinders, they can be combined with most mechanical EVVA systems.

Xesar escutcheons

Xesar escutcheons combine the benefits of a mechanical escutcheon and an electronic locking system. Thanks to the slim design and clear lines, the integrated reader unit is hardly noticeable. Xesar escutcheons can also be used variably: for solid or metal frame doors in indoor and outdoor areas as well as fire doors and emergency exit doors with panic bars.

All Xesar identification media are based on secure Mifare Desfire EV1 technology.

The Xesar interface

You can control the functions of the Xesar system administration directly from your own software using the MQTT interface.

Your software needs to be adjusted to allow the Xesar system administration to communicate with your software. The best person to do this is your software integrator or programmer. Use of the Xesar interface is free of charge.

You can find application examples and the interface documentation  here.

Application examples

Personnel management made easy

An employee gets new duties and moves to another department. Changes to the corresponding access authorisations are automatically sent via the interface from the personnel management software to the Xesar system administration software.

New employees

A new employee starts on 1 June and receives an access card with the corresponding access authorisations. This is automatically sent via the interface from the personnel management software to the Xesar system administration software.

Rapid system commissioning

The EVVA Partner installs a new Xesar system and has to enter a lot of installation locations according to the building plan. With the Xesar import tool, this can be done via the Xesar interface at the touch of a button with the corresponding list in CSV format.

Door button on desktop

Your reception desk constantly has to open the storage door for suppliers remotely. This can be done with a shortcut on the desktop via the Xesar interface without having to use the administration software.

Presence indicator

As a building manager, I want to know at all times who is currently in the building so that I can systematically evacuate the building in the event of a fire. In addition to the single entry access control system, I also need the details of the people present, which I receive via the Xesar interface.

[Translate to UK:] KeyCredits 10, 50, 100 Stück

Full cost control

Thanks to flexible KeyCredits you are in absolute control of your Xesar system. Opt for individual KeyCredits to manage small and medium-sized systems with fewer authorisation changes. The KeyCredit Xesar Lifetime option, for software version 3.0, is ideal for large master key systems with frequent changes to authorisations.

A KeyCredit is debited if access authorisations are changed or created. KeyCredits are available from all EVVA Partners. Purchased credits are uploaded to the Xesar software, which is also used to assign access authorisations.

KeyCredits 10, 50, 100

For systems with just a few users and/or infrequent changes to access authorisations, we offer KeyCredits with 10, 50 or 100 units.

KeyCredits Xesar Lifetime

The KeyCredit Xesar Lifetime offers you unlimited creation of as well as changes to identification media with any number of access authorisations for the entire lifetime of the software version installed.

[Translate to UK:] KeyCredits Unlimited

The virtual network

The virtual network uses the issued identification media in circulation to exchange information between doors and software. Xesar online wall readers represent the reliable security interface within Xesar systems. They enable permanent security updates and keep the system safe and up to date.

Versatile application options

Be it in residential properties, companies or public institutions – many people come in and out every day, but not everyone is allowed access to all areas. Changing access authorisations and high levels of employee fluctuation further complicate the situation. Consequently, it is a challenge for operators of locking systems to organise them efficiently, safely and in a controlled manner. Xesar helps you to efficiently organise procedures and gives you the required degree of flexibility so you can quickly react to changing circumstances.
