Density is a San Francisco-based company building a people-counting system to measure the number of people in or passing through a physical space such as a hallway, lobby, or conference hall.
Density is a developer of door sensors and room sensors that are designed to measure how people use space in real time without invading privacy. The company's proprietary depth sensors and deep learning algorithms accurately and anonymously count people in real time. Density suggests the measuring technology can help design and manage spaces used by people to be more inclusive and sustainable. Density's sensors do not use cameras, in order to avoid capturing personal identifiable information; they are purpose-built for measuring how people use spaces.
