Cable extended to more than 200 feet.
The camera
power supply/power splitter combination is only
designed to power cameras up to 200 feet. Any cameras
beyond that distance will need their own power supply
which is available at

.
Dark video image. Some cameras feature an infrared
cut filter to improve daytime video images. This can
sometimes get stuck. Place a hand over the lens for 10
seconds to trigger night vision mode. You may hear a
soft click as the filter resets.
Upside down video image. Change the position of
your camera to correct. Or, click on the live video from
that camera. A tool bar will appear above the video
image. Click on the
icon to open the Image Adjust
window. Select the Flip option at the bottom.
Camera looking through window has video image
during day, but not at night.
The LEDs on the camera
act as a flashlight and, at night, this light is being
reflected by the window back at the camera. You will
need to reposition the camera outside the window.
Camera video is very dark during one time of day,
but lighter during others.
Reposition the camera. Any
sun or artificial light shining directly onto the lens will
backlight the subjects in the camera’s field of view and
cause them to appear dark and/or washed out. Keep in
mind that the sun changes positions over the course of a
year as well as during the day.
Camera on a metal building has excessive static.
The camera will need to be separated from the metal
building by using a rubber gasket.
