any holes through an external wall for a cable, ensure the hole is sealed
up using a suitable sealant to prevent drafts.
To prevent a fire or electrical shock hazard, do not attempt to open the
housing while the camera is exposed to rain water or wet conditions. Do
not expose any wiring connections to weathering. If terminating any wiring
connections outdoors then use a suitable weathering box to insulate the
connections.

Camera Installation
 Avoid positioning the camera so that it is facing directly at the sun as
this will impair the picture quality viewed.
 Avoid pointing the camera lens directly through clear glass as the night
vision LEDs will cause a blurred image at night.
 Avoid pointing the camera directly at any bushes, tree branches or
moving objects that might naturally move due to winds. This is also
because if you need to use the motion detection feature in the PC
software to record movement the software might record unnecessarily.
