5.4.7.1 Filter Types
Each DCx camera has a filter glass in the front flange to prevent the entry of dust particles. Color
cameras by default use an IR cut filter, which is required to ensure correct color rendering. The
default filter glass in monochrome cameras has no filter effect. Every camera model is available
with different filter variants such as daylight cut filters (type DL).
