Success retrofit case study for residential building

Success story Enhancing resident experience in a 50-year-old residential building

The Challenge Residential retrofit building in Prague

In a decades-old residential building in Prague, the outdated door communication system was barely functional. While a basic replacement was an option, residents opted for a meaningful upgrade with minimal disruption and no need for new cabling.

The solution

Our retrofit solution delivered reliable door communication and significantly enhanced the resident experience.

The advantages

  • Residents now enjoy modern features like mobile access and answering intercom calls on their phones. They can even call the elevator to their floor directly from the indoor station as they leave their apartment.
