Secure transfer of the data

The deisterCloud serves as a routing service for all smartphone data. All data in the cloud is always encrypted so that no security risk can arise.

Data can be transmitted in real time via the cloud. User logins and bidirectional exchanges from and to the user are possible at any time.

If the cloud connection is interrupted, the smartphone stores the data locally until the connection is re-established - the data is then synchronised losslessly so that nothing is lost and all time stamps are also recorded properly.

  • Secure hosting in Germany
  • No data loss even in case of connection failures
  • Real-time data exchange

guardiX® II

Robust data collector

Our guardiX® II data collectors are characterised by their extremely handy and simple operation. They read RFID-based checkpoints without contact. The read data is provided with date / time and stored for later transmission and processing. Optical signals as well as vibration give the user immediate feedback on the successful detection of the respective checkpoint.

With their robust design without moving parts and IP67 certification, guardiX® II data collectors are perfect for harsh environments and everyday use. Especially where patrols need to be carried out discreetly, or in noisy environments, vibration is a great advantage as feedback for the detection of a checkpoint. The excellent battery life with standard AA batteries results from the economical vibration function, which means that up to 500,000 checkpoints can be read with one set of batteries.

  • Wear-free and contactless checkpoint detection
  • Compatible with all previous deister electronic evaluation systems
  • Very long battery life
  • Robust design without moving parts
  • Very easy to use, no extensive training necessary

Event cards

Event cards

Additional round information

With the event cards, the security service provider can document additional events along the round. For example, it can be noted that a window is open or that a smoke detector is defective.

The security guard carries the event cards with him/her and can simply hold the corresponding card in front of the data collector when needed. According to the area of application, the significance and evaluation of the events is determined by the user of the system himself/herself.

  • Simple operation
  • Define own events
  • Detailed documentation

125 kHz and NFC combined

Checkpoints store their information digitally in an RFID chip, which is read contactless by smartphone or data collector, avoiding the wear and tear of a checkpoint.

The checkpoints support two technologies: 125 kHz and NFC, ensuring that the dataLog system offers maximum compatibility. Old and new data collectors like guardiX® II as well as apps like the deisterCheck app can be used.

The small, inconspicuous plastic housing can either be glued or fixed with a special screw for more security. The checkpoints are insensitive to changing temperatures, weather, dirt and other environmental influences. Passive operation eliminates the need for a battery.

Benefits of our solution

Aufgabenlisten deisterCheck App


Checklists, selection lists, instructions

It is not uncommon for a security guard to take on important additional tasks on his round. In order to instruct and document these tasks, special functions can be linked to a checkpoint of the round, which, for example, displays a checklist with concrete instructions for actions to be taken when the checkpoint is read out. The processing is also logged in the reporting system.

  • Freely createable checklists
  • Selection of self-created states
  • Instructions and notifications
Upload photo deisterCeck

Photos for advanced reporting

Take pictures and write comments

During the round, a photo can be taken at any time via the app. The photo is automatically documented with a time stamp. The photos also appear later in the reports and can be additionally annotated, e.g. "Open window: 1st floor, room UF.01.34".


Checkpoint KSC 30

125kHz and NFC

Connecting old and new world

The dataLog® system is compatible with both 125 kHz and NFC checkpoints (although smartphones can only read NFC checkpoints). This means that smartphones and data collectors can be used side by side in the same system and old 125 kHz checkpoints do not necessarily need to be replaced.


guardiX Connect Dockingstation

Unique hybrid solution

Flexible and independent

The guardiX Connect docking station connects to the software for uploading the round data from anywhere in the world - and does not need a connection to the end customer's IT infrastructure to do so. The data is sent via the built-in cellular communication module. This makes the proven guardix II data collector even more flexible to use.


Slots for keyTags with keyTag retrieval

Integration with electronic key cabinets

Key management

As soon as clients hand over their keys to a security service, a lot of responsibility is handed over at the same time. It is of utmost importance to store these keys in a responsible, verifiable and well-managed manner. An electronic key cabinet makes it possible and also offers many other functions that lead to more cost efficiency and reliability in the processes.

Both dataLog® security guard and proxSafe® key management are managed in the same central software at deister electronic and are holistically integrated with each other. The security staff can automatically receive the rights for key removal based on round scheduling. Each key removal and return is electronically monitored and documented.

  • Automatic assignment of rights for key removal
  • Electronic documentation of every key removal and return
  • Automatic notification if keys are not returned on time
  • Keys are sealed tamper-proof on RFID keyTags
