Fall-detection systems may use wearable inertial sensors, cameras, radar, acoustic sensors, or combinations of modalities. Wearables often use accelerometers and gyroscopes, but depend on the person wearing and charging the device; ambient sensors can operate without a wearable but raise questions about data collection, consent, and household context. Radio-frequency or radar sensing can be less visually revealing than ordinary video, but it is not inherently private or risk-free. Fall detection and fall-risk assessment are different tasks with different labels and evaluation requirements. Studies and reviews report varied methods and validation settings, so lab performance should not be treated as proof of reliable home deployment. Design should give older adults and caregivers understandable choices, access controls, and ways to pause or correct monitoring. Safety tools should complement care relationships and preserve autonomy and dignity.
