Personal IR tester

IR Sight

peak 0

quiet

Point at a TV remote button in a dim room. A real IR LED shows as a small bright pinpoint.

Sensitivity200

Only compact magenta/IR pinpoints count now. Point at a TV remote in the dark to confirm. Raise this if lamps still mark.

Activity notebook

When a tiny bright IR-like pinpoint shows up, a still is saved here and a line is written to ir-activity.txt so it can be analyzed later. Lamps and windows are ignored.
