The patented camera system is used as a surveillance device, particularly for monitoring underground sewers and manholes.
Heavy rainfall and flooding pose a challenge to the wastewater industry’s many underground shafts and sewer structures. They must be inspected regularly to check for dirt and blockages.
Unsatisfactory existing solutions
Camera systems using standard camera modules are already being used to reduce inspection times. These usually require a power supply. Mounting is difficult in the usually poor lighting conditions, and the cumbersome handling of a laptop to set up the camera is often difficult. The results of all known systems are therefore unsatisfactory. Once the images have been analysed, it is often necessary to readjust the camera on site. This means that the system that is supposed to save money becomes a cost factor and economic operation is not possible.
Innovative, economical & practical solution
The patented optical monitoring device uses a laser to roughly adjust the image section. Fine tuning is then done on the PC in the office. Fine tuning can be done at any time, even from the office.
The digitally defined monitoring area is then photographed at regular intervals and transmitted via GSM to the central server platform. Contamination and blockages can be detected centrally without the need for an operator to physically travel to the sewer structure.
The camera also features LEDs to illuminate the area of interest. The camera is battery powered and transmits data via GSM to the central server platform. This means that no on-site infrastructure is required.
The patented optical monitoring device has no mechanical components, giving further advantages in terms of wear and maintenance.

Huge savings potential in the wastewater sector
The patented camera system for monitoring manholes and shafts makes installation, assembly and operation much easier. For the first time, it is now possible to operate such an optical monitoring system economically, and the potential savings for sewer operators are enormous.
The patented solution is already integrated in the D-Eye® from the Danish company Danova.
