Imagine a technology that can monitor people behaviour without needing cameras and wearables.

At Xetal we have developed Kinsei: an innovative indoor people localization technology that does not require a person wearing or carrying any type of device or phone. Kinsei relies on proprietary positioning sensors placed on walls, beds or door frames to detect and track of one or more people with an accuracy of about 30cm. When such an accurate position information is used together with knowledge about the room itself, it is possible to understand what is happening in the room, what people are doing and determine what is likely to happen next.
