FLOW M
People Flow Counting M 2.0
HOW MANY PEOPLE ARE FLOWING THROUGH THIS NARROW PASSAGE?
FLOW M is a budget-friendly people-counting solution and a cost-effective alternative to the flagship FLOW product. It is ideal for narrow passages and doorways up to 0.9m wide. For larger installations, FLOW M can be combined with other Terabee sensors to reduce overall project costs.
Terabee FLOW M is an affordable solution for low-traffic areas such as small meeting rooms, offices and bathrooms.
FLOW M is effective for standard doors and entrances up to 0.9m wide where people pass one by one. If multiple people are likely to cross simultaneously, consider upgrading to FLOW.
FLOW M provides a high level of accuracy above 95%, while being the most affordable solution, when properly installed and used.
This product is powered by Time-of-Flight 3D sensing technology and ensures privacy protection in any situation. FLOW M does not include any camera or microphone, thus ensuring that privacy is respected even at the source of the sensor – no personal images or data can be extracted.
FLOW M can simultaneously send digital data to servers for collection and analytics and control local equipment, such as lighting and ventilation systems. This is achieved by sending a simple 0-10V analog signal that corresponds to the occupancy level of the designated space.
Unlike our competition, we do not force customers and partners to enroll in subscriptions or SaaS models. We consider ourselves part of the infrastructure, focused on delivering top-quality products and data, regardless of where that data is stored. Our devices can transmit data to any chosen server – local or cloud-based – irrespective of ownership. While we are always happy to offer support, we do not mandate the use of our servers or additional services.
