About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

MATHFEL
Door intercom system for apartment buildings

Product description of the manufacturer

The Mathfel door intercom is a modern, digital solution that is characterised by its flexibility, user-friendliness and simple installation. It is suitable for new buildings as well as for retrofitting existing buildings and offers a wide range of functions for secure and convenient access. The high-resolution video transmission ensures clear identification of visitors, while Starlight cameras provide reliable images even in poor lighting conditions. The intuitive configuration enables quick commissioning without extensive technical knowledge. In addition, the system supports different types of cabling such as series connection or star-shaped distribution, which ensures a high degree of customisability. It is designed for up to 64 residential units and is therefore also suitable for larger residential complexes or villas.

In our tests, the system impressed with its clear audio and video quality, stable app connection and reliable door opener function. The well thought-out design and ease of operation are also favourable. The only point for improvement is the use of plastic film in the packaging. A specialist is recommended for installation.

  • Very good camera
  • Well-functioning app
  • Clear voice picture
  • A professional is recommended for installation
  • Little effort made for sustainability
