Visual smoke detection

Using existing cameras to detect visible smoke or flame cues in approved zones.

What it means

Visual smoke detection analyzes camera views for plume, smoke-like movement, flame-like light, and scene context. It is an added visual layer, not a replacement for required fire systems.

Why it matters

In some zones, smoke can be visible before heat reaches a ceiling sensor. The useful pilot question is whether the alert reaches a person who can verify and act.

Evaluation questions

Which zones have visible risk before ceiling detection?

How are dust, steam, welding, and exhaust handled?

Who verifies and escalates the alert?
