IR-LED Illumination
2.7.1
Axis M1145
Specification:
n/a
(the Axis M1145 camera module does not have
integrated IR LED illumination with additional
photo diode for measuring the light conditions)
2.7.2
Axis M1145-L
Specification:
2 x highly efficient LEDs
6
- with optimized infrared spectral components
(
λ
centroid
= 850 [nm]), allows high-contrast
black and white pictures in darkness and un-
der difficult light conditions
- Adjustable intensity and illumination angle,
typical range up to 15 m
- Light sensor for automatic activation or deac-
tivation of the infrared diodes
- Includes a particularly developed chloroprene
rubber adapter for limiting the scattering an-
gle due to infrared light reflections within the
pressure resistant housing (q.v. optimization
of shadowing and interferences due to multi-
ple LED light reflections at the borosilicate
sight glass of the stainless steel housing)
- Radiation angle: Max 30°

Depending on the adjusted illumination angle, it is possible that at turned on IR LED illumination, the angle of view is slightly restrict-
ed or a minor shadowing is noticeable
