Sightline turns the security cameras a site already has into a real-time safety spotter. It connects to existing CCTV over standard RTSP, so there's no new hardware, and it watches for hazards: a hand in a machine's danger zone, a missing helmet or a missing hi-vis vest. Each alert names the safety factor that triggered it, gets checked by Muse Spark before it reaches anyone, and lands on the supervisor's Android phone. The phone gets a push notification and a replay clip where SAM 3.1 circles the person or object involved. Sightline makes one model call per incident, so a hazard that lasts a minute doesn't flood the supervisor or the bill.
