Cleaning the Dome and Lens Cover
The dome and lens cover of the AVX-HD848IRM are extremely durable but can be damaged if
cleaned improperly.
To Clean the Dome and Lens Cover:
•
To clean dust or loose dirt, use compressed air.
•
To clean smudges or stuck on dirt, use warm water with a few drops of dish soap and a
clean microfiber cloth.
CAUTION:
Do not use solvents, paper towels, newspaper, or other rough materials to clean the
dome cover. This can scratch the dome and lens cover and cause IR distortion.
Considerations for Infrared (IR) Lights
Environmental factors can limit the performance of night vision using IR illuminator lights. Infrared
light behaves the same as visible light and will reflect off of bright or shiny objects and overexpose the
image. The camera will adjust to properly expose the bright areas of the image, which may leave the
dark areas obscured.
For best IR Night Vision performance:
Be aware of surfaces that can cause IR light to reflect into the camera.
•
Reflective or light-colored surfaces and objects close to the camera can reflect IR light
back into the camera.
o
Remove the reflective or light-colored surfaces.
o
Cover the reflecting surfaces with a non-reflective material (non-reflective
tape, dark paint)
o
Mount the camera on a nearby wall using a mounting bracket.
