Health Sensing Moves Cameras Beyond Reassurance Devices
Respiratory rate extraction from video, gait irregularity detection and activity baselining have moved from research demonstrations into shipping products over the past three years. The commercial point is not clinical accuracy, which remains limited, but retention: a subscription that reports a trend line gives the owner a reason to keep paying after separation anxiety resolves. Units carrying these features hold twelve-month retention roughly 22 points above the category average. Development cost is largely software rather than sensor hardware, which is why the feature has spread faster than most in this category.
