    Sophisticated Access Control Solutions

    Your key access control issues solved

    JanusC4 is a customisable, integration-centric proprietary software with innovative blade-based hardware. It focuses on versatility and usability for customers, users and installers.

    Cost effective, easy to install, customer friendly

    It has been a pleasure to work with Grosvenor Technology consistently over the last 5 years. We have built a mutually beneficial relationship through collaboration on various projects and utilised the quality of Grosvenor products on many of our clients’ sites. The product is cost effective, easy to install, customer friendly and the business provides a strong level of technical support.

    The entire installation was much more cost effective

    It was clear that Grosvenor offered a platform that would provide additional functionality as the organisation grew, rather than starting over each time Misco required new features. The hardware was easy to deploy and the entire installation was much more cost effective and intuitive than what came before.

    A productive partnership

    We enjoy a productive partnership with Grosvenor Technology with the high quality products, excellent sales support and technical back up. We supply and install JanusC4 to a myriad of customers from small single door Parish Rooms, Schools and Councils all the way through to High Security Government Institutions.

    Gives us all peace of mind

    Putting access control in place has meant that we have been able to extend our opening hours, content in the knowledge that we still know exactly who has access to the building. Not having to physically ‘lock-up’ at 11pm at night saves us both time and money; being protected by Grosvenor Technology gives us all peace of mind and is worth its weight in gold.
