Don’t know if LEDs are
“ON”
850nm LEDs will have a
faint red glow when
“ON”.940nm LEDs are
covert. Aim the LEDs
directly at an IR sensitive
camera to see the lights
or wait for the LEDs to
warm up (two minutes).
Feel for warmth.
LEDs are not “ON” Cover the photo sensor
to activate power to the
LEDs (up to 30 seconds
delay for activation).
Adjust the photocell’s
variable resistor towards
the “ON” position. Adjust
