Electronic Access Control Systems

Modern access control with extensive reader portfolio and wireless smartlocks – always the right solution for every door.

Powerful access control

The right solution for every door

doorLoxx® is our comprehensive access control system and provides an easy and cost-effective way to switch from a conventional locking system to a fully-fledged electronic access control system. The extensive product portfolio always offers the optimal solution for every type of door.

Important high-traffic doors such as the main entrance are controlled with an online reader and controller. Office doors and meeting rooms can be managed at the click of a mouse using offline cylinders and electronic fittings. All other conventional keys are automatically managed in our electronic key cabinets.


This means that every door in the building can be integrated cost-efficiently and according to the requirements whilst being manageable via software.

deister credentials offer the highest level of security and use the latest secure MIFARE® DESFire technology with customised CryptoKey handling.

"We are very satisfied with the hardware and software from deister electronic. The intelligent systems meet all our requirements. We can now easily and accurately track who has access where and when."

Johann Penner, Chairman of the ECG Hanover

"After the initial installation, the delivered devices worked 100% flawlessly without us having to take any further care of them. Our system partner deister electronic really has a clean slate here!"

Peter Matz, Managing Director at GemiTeam Gesellschaft für Software-Systeme mbH

Access control readers

One reader, all technologies

The timeless design provides a high-quality look and deister electronic's proven reading performance ensures fast and smooth operation. The readers are available in three different shapes to match the available space at the door. The reader's LEDs clearly indicate the status to the user. Even users with a red/green deficiency can recognise the status of the reader based on the LED positions. The readers feature a replaceable cover. Even after many years of use, you can make it look like brand new just by replacing the reader cover.

In addition to proven reading technologies such as MIFARE® Classic and MIFARE® DESFire, Bluetooth® and NFC™ are also supported. The readers have an open interface (Triple Technology™) to retrofit existing or future technologies, so you remain future-proof with the Infinity Readers™.

Electronic cylinder with RFID

Electronic cylinder

Easy to upgrade

Just like a mechanical cylinder, the electronic cylinder can be installed in just a few steps. No drilling or other modifications to the door are required because the design is identical. The basic cylinder bodies can be ordered in five different installation lengths, including a half cylinder, and can also be adjusted in length directly during installation using spacers, meaning that the length can be adjusted in 5 mm steps from 30/30 to 45/75.

  • Installation length can still be adjusted during installation
  • Best quality - Made in Germany
  • Fast reading speed
Electronic door fitting with RFID

Electronic door fitting

Suitable for every door

The electronic fitting suits any door with its slim and simple design. The handle can be selected from four different models, depending on its use on solid or tubular frame doors. For mounting, the same drill holes as for a conventional fitting can be used.

The cover plate allows the parallel use of the existing cylinder for secure door locking or the elegant covering of the cylinder opening. The exchangeable cover plate allows adaptation to doors with different distances between handle and cylinder. The Digital Handle adapts perfectly to any door.

  • Suitable for every door
  • Slim and elegant design
  • Additional mechanical locking cylinder (optional)
  • Simple battery change


Electronic lock with RFID

Electronic lock

Design meets security

The electronic motor lock has been developed for self-locking locks and combines security with design. The simple design can be discreetly combined with the design of the door handle and offers maximum freedom in the choice of shape and colour.

In addition, the electronic lock offers more security because neither damage nor forcible removal of the housing or electronics allows access to the lock mechanism inside the door.

  •     Maximum freedom for design
  •     More security
  •     Different designs to suit every door

This means that the Digital Safe can also be seamlessly integrated into an existing access control system and can be opened with the same credentials. The Digital Safe can also be flush mounted, providing the best possible mechanical protection. Weather impacts are also minimised by this type of installation.

  • 70 mm diameter
  • Enough space for ISO cards and large bunches of keys
  • Independent of local IT infrastructure 
  • Standalone capable
  • Weatherproof IP65 metal housing
  • Content monitoring

WCU 2 Offline door control

Reader with integrated door control

The WCU 2 door control module is a reader with integrated inputs and outputs. It only requires a power supply, but is otherwise integrated into the system like an electronic cylinder.

Wherever an existing online reader is to be replaced and the functionality of an electronic cylinder is not sufficient, the WCU 2 is the ideal solution.

  • Integration into the system, like an offline reader
  • Only power cabling required
  • Available with integrated or remote reader

Cost efficiency

The right solution for every door

Not every door is the same, therefore not every reader is suitable for every door. There are different types of doors in a building (e.g. from the main entrance to the office door) with varying security requirements. With our extensive product portfolio, we provide the appropriate, cost-effective solution for every door.




Bluetooth interface



Using smartphones as ID cards offers completely new possibilities and flexibility and can be used in our access control system as an alternative or as the only ID for a user. For this purpose, both the online readers and the battery-powered readers can be equipped with a BLE interface.

Our app and cloud infrastructure provide highly secure communication between devices to meet current IT security standards. The data remains highly encrypted from its origin in our software until it is processed in the reader.
