black lead from the power wire pig tail. Use the gray wire nuts provided with your system and twist
them onto the wires until they are firmly secured.

Step 3
Now connect the other end of the extended power cable to the power supply. First strip
the wires back as detailed in Step 1. The power supply designates which terminal is positive and
negative. Insert the red wire under the positive terminal and the black wire under the negative
terminal. Now tighten down the terminal screws.

Finally, connect the power pig tail to the camera’s power lead, as shown.
4.3 How To Place Cameras and Connection Tips
•
Camera lenses can provide a wide-angle view or a long-distance view. As camera lens sizes (in
millimeters) increase, the camera can see greater detail at a greater distance , but the angle of
view decreases. Using a 3.6 mm lens, one may only be able to recognize faces up to 10-15 feet
away, but the camera can provide a wide 70 degree viewing angle. A 25 mm lens may provide
the same detail from 70 feet away, but the camera can only provide a narrow 11 degree
viewing angle.
•
A sturdy, durable, protective housing is necessary for an outdoor camera installation.
Depending on the climate in your location, you will need to consider the temperature ranges
your cameras will need to endure.

camera installation
•
It is recommend you do not use any camera in an outdoor setting that is intended to be
used only indoors. Even if the camera is not directly exposed to rain, snow, or direct sunlight,
the camera housing and components are not sealed and properly protected from extreme
temperatures or potential moisture accumulation. You can, however, use any camera intended
for outdoor use in an indoor application.
•
Avoid mounting cameras on a metal surface. Conductive surfaces can not only create
interference, but can also cause damage from power surges or electrical storms.

•
Avoid running cables near strong sources of interference. Common sources of interference are
fluorescent lights, electrical appliances, and 110 V power cabling/outlets.
•
If you experience frequent electrical storms or other hazardous electrical surges, it is
recommended you use inline coax cable surge protectors for your outdoor cameras. This will
protect your DVR, time-lapse recorder, and the other cameras from any high voltage surges.
