ZOKA – Safety and Communication


RK safetec is the supplier of the monitoring and communication system ZOKA, which was specifically developed for the safe and efficient handling of major construction sites.

Access Systems

The ZOKA Access Module can manage and control access to secured areas and zones for authorised persons and vehicles.

Positioning Systems / Person Identification

The ZOKA Positioning Module enables the positioning and recording of persons, vehicles and equipment in real time. Depending on the desired system structure, positioning is carried out according to zones or defined detection areas.

Communication Systems / Radio Technology

Construction communication plays a central role in safe construction coordination in tunnels and on major construction sites. It guarantees that the connection to the outside world remains intact and that the exchange of information within the area functions well.

Network Technology

For a secure connection of the ZOKA system components, they are connected via a redundant fibre optic cable network or a secure UMTS/LTE radio connection.

Alarm Systems

The ZOKA Alarm Module enables both centralised and decentralised alarming over the entire construction site or individual sections of a construction area.

Video Surveillance

RK safetec offers an adapted ZOKA Video Module for monitoring individual entrances or entire construction site and tunnel areas, in which high-quality components but cost-effective technology is used.

Site Monitoring


As a complete solution provider, RK safetec offers a wide range of automation and monitoring solutions for the monitoring, control and visualisation of all systems and plants.

System Control

The communication distribution cabinets (KVS) used in the ZOKA system can be flexibly expanded and can thus control external devices such as jet fans, ventilation flaps, fire alarm systems etc. and forward their data to the evaluation point.

Construction Site Lighting

RK safetec plans and implements the optimal solution, from normal fluorescent tubes to the most modern LED technology, depending on the demands and safety requirements to be met.

Power Supply

RK safetec offers the right power supply for every project – whether it is in the medium-voltage or low-voltage range - which can be implemented both temporarily during the construction period and permanently for the final completion. If required, the power supply can be implemented redundantly via an additional emergency power supply.
