24 alternatives to A bedside camera detects REM sleep and agrees with a clinical EEG
I build a device called the INSPEC that detects REM sleep from a bedside infrared camera instead of electrodes. It watches the face under IR light and measures frame-to-frame pixel variance in the eye region. During quiet sleep the face is stable. During REM the eye movements under the lids produce measurable variance, which the device aggregates over time before it flags a REM period. Toss detection, whole-frame motion rejection, and face tracking filter out body movement and out-of-frame periods. After I gave a talk on contactless REM detection, a sleep lab loaned me a clinical-grade EEG…
INSPEC is a bedside infrared camera system that detects REM sleep without electrodes by tracking eye movements beneath closed eyelids. The device measures pixel variance in the eye region under infrared light, using… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Hi everyone, I'm the author of ESPectre. This is an open-source (GPLv3) project that uses Wi-Fi signal analysis to detect motion using CSI data, and it has already garnered almost 2,000 stars in two weeks. Key technical details: - The system does NOT use Machine Learning, it relies purely on Math. — Runs in real-time on a super affordable chip like the ESP32. - It integrates seamlessly with Home Assistant via MQTT.

Hi HN! I suffered from chronic insomnia for over a year and tried everything from cutting coffee, blocking blue light, to taking melatonin and antihistamine, but couldn’t find anything that worked. I even bought a $500 research-grade EEG device to track my sleep, which was honestly kind of depressing because it showed that I was sleeping less than 4 hours per night for weeks straight. In the day, it took an immense amount of energy for me to perform even the most mundane of tasks, such as doing my laundry or ordering groceries. At night, I felt an overwhelming sense of loneliness and…
