Night Vision - Response QC 3670 Operation Instruction Manual

Camera(s) and DVR
Do not attempt to open the units with the power adaptor plug connected to avoid any risk
of personal injury.
When installing CCTV camera(s), always follow manufacturer's advice when using power
tools, steps, ladders, etc. and wear suitable protective equipment (e.g. safety goggles)
when drilling holes. Before drilling holes through walls check for hidden electricity cables
and water pipes. The use of cable/pipe detector is advisable.
It is also advisable to avoid exposing any cameras to extreme weather conditions (e.g,
under a gutter which is prone to any water leaks). When installing any cameras with this
unit, it is advisable to use cable conduit to protect any video/power extension cables
from being exposed externally and to prevent/reduce the chances of the cables being
tampered with. After drilling any hole though an external wall for a cable, ensure the hole
is sealed up around the cable using a sealant to prevent drafts.
To prevent a fire or electrical shock hazard, do not attempt to open the housing while
the unit is exposed to rain, water or wet conditions. There are no user serviceable
parts inside. Refer servicing to qualified service personnel. Avoid pointing the
camera(s) directly at the sun or any bushes, tree branches or moving objects that might
unnecessary cause the DVR to record due to winds for example. The system also
provides "Masking" function, and the user may screen out motion detection area in parts
of the picture which motion detection is not required.
