The following installation guidelines are recommended to prevent degradation in captured
image quality.
1.
Maintain 2 mm distance between Holder Camera and Holder IR Filter.
2.
Use a ring-shaped elastic material such as Poron as a sealing sponge and have it
compressed between Holder IR Filter and Camera Lens to prevent the interference of IR
LED light. When doing so, the camera hole and the center of a sphere need to be
matched to avoid interference in capture view angle.
Use the same or similar sealing material and have it compressed between Holder IR
Filter and IR LED to prevent the IR LED light from leaking in different directions.
3.
Maintain the minimum of 3.5 mm as the IR LED light transmission hole diameter;
otherwise, the images will turn out dim.
4.
Maintain the minimum of 5.0 mm as the camera light transmission hole diameter;
otherwise, the capture errors may occur.
5.
Maintain the minimum of 4.0 mm as the Camera Sealing; otherwise, the capture errors
may occur.
6.
Maintain the minimum of 2.5 mm as the IR LED Sealing hole diameter; otherwise, the
images will turn out dim.
