Letterbox with Comelit Switch & Ultra - Smart door communication for modern entrance areas
A letterbox with Comelit Switch or Ultra combines state-of-the-art video door intercom technology with high-quality design and durable materials. These smart solutions for your entrance area not only offer a convenient way of communicating, but also an elegant and robust appearance. The combination of a stylish letterbox and the innovative Comelit systems ensures maximum security, convenience and aesthetics.
The Comelit video intercom systems from the Switch and Ultra series set new standards in door communication. Both systems offer simple and intuitive operation as well as a wide range of functions that ensure security and convenience. The Comelit Switch series is characterised by its modular design and high-quality workmanship. It enables simple customisation to individual requirements. The Ultra series impresses with its modern, elegant aesthetics and is particularly robust so that it can withstand the harshest weather conditions.

High-quality materials and durable design
A letterbox with Comelit Switch or Ultra not only offers smart technology, but also outstanding material quality. At Briefkasten Manufaktur, we rely on materials such as stainless steel, which is known for its corrosion resistance, durability and elegant appearance. These properties make stainless steel the ideal choice for outdoor areas, as it can easily withstand the daily effects of the weather.
The combination of stainless steel letterboxes and the robust Comelit outdoor intercoms ensures that your entrance area is not only functional but also visually appealing. You can also choose between different variants and colours to perfectly match the letterbox to the design of your home.

Flexible and expandable systems
A major advantage of the Comelit Ultra series is its modularity. You can configure the system entirely according to your individual requirements. This means you can integrate additional functions such as an HD camera, extended bell modules or labelling modules. This makes the letterbox solutions suitable for single-family homes as well as apartment blocks or commercial properties.
Compatibility with modern smart home systems is particularly practical. With the associated Comelit app, you can see who is at the door at any time via your smartphone or tablet and open the door if necessary. These functions provide additional security and convenience.
Focus on security and convenience
Comelit video intercom systems not only offer high-quality communication technology, but also a high level of security. The integrated video function allows you to see visitors before you open the door. The option to receive notifications on your smartphone when someone rings the doorbell also significantly increases the security aspect. The systems are also easy to operate, making them an ideal solution for homes and businesses that prioritise convenience and security.
