CAMERA PLACEMENT
When installing your camera, it is important to select a proper site not only for field of view, but for
other considerations as well:
Distance from viewing/recording device
. The further the camera is from the DVR
or monitor, the higher the chances of signal degradation. Typical 75Ω Video Cable provides
acceptable signal at distances up to 200’ (60m). At greater distances, UL-Listed shielded RG59
should be used. The camera’s power supply should be located as near to the camera as possible
when the distance exceeds 200’ as the power level will drop over extended distances resulting in
a decrease in video quality.
Do not place near high voltage wires or other sources of electrical
interference.
Electrical interference will degrade the quality of the signal.
Place camera out of reach to avoid damage.
Avoid direct exposure to weather.
Do not place the camera where rain or snow will hit
the lens directly nor should the camera be placed so that the sun or bright light shines directly
into the lens. Your camera is weatherproof, but it will not work when submerged in water. Ensure
that all power and video connections are not directly exposed to water and are protected from
the elements.
Indoor cameras should not be used outdoors.
Even if they are in a sheltered location,
they can still suffer damage due to humidity, dust and other environmental factors. Each camera
has an Ingress Protection (IP) rating which defines how protected the internal workings of the
camera are from solid objects - such as fingers or bugs - dust and moisture. In an IP rating, there
are two numbers that follow the letters “IP.” The first represents the protection from solids while
the second represents the housing’s protection from moisture. A camera should have a minimum
rating of IP65 for trouble-free use outdoors.
Mounting surface.
The mounting surface must be sturdy and able to hold at least five times
the camera’s total weight.
Legal Considerations.
Always check state and local laws before installing cameras. (2011
NEC 820.44)
Do not place camera behind a window.
If there is a light source behind the camera,
it can cause a reflection in the window that will obscure events on the other side of the glass.
Likewise, the camera’s infrared LEDs will reflect off the glass and shine into the lens, thus
degrading the image.
Light levels should be approximately
the same between camera and target
area.
A camera in a brightly-lit area looking
into a shaded area, or vice versa, may produce
inadequate results.
The above are guidelines and the optimal
location for your camera will depend on your
unique circumstances. As a general rule, the
locations highlighted in
Green
in the picture to
the right indicate the best locations to mount
your camera. Both locations are sheltered from
rain or snow and offer good sight lines to allow
your camera to monitor a wide area.

CONNECTING CAMERAS
Your DVR uses BNC connectors and ports to ensure quick and secure connections for your
cameras’ video cables. While both conventional analog and digital SDI (Serial Digital Interface)
high definition cameras use this interface, they cannot be connected to a port intended for
the other type because of incompatible signals. It is therefore important to ensure that you are
attempting to connect to the proper port.

Some camera bundles may contain more than one camera power supply and splitter. Repeat
the steps above as necessary to connect all of your cameras. For bundles containing multiple
types of cameras, make sure to connect to the proper power supply as mixing and matching
may either cause damage or insufficient power to your cameras.
You may now mount your cameras.
STEP 4.
Repeat for each camera included with your package to ensure proper
connection and function.
STEP 5.
Connect the single end of the power splitter to the power adapter.
STEP 6.
Plug the power adapter into a surge protector. You should now see a live video
feed from each of your cameras.

STEP 1.
Connect the BNC and power leads on the camera to the matching connectors
on the power and video cable.
NOTE:
The male power end fits into the matching power lead on the camera.
STEP 2.
Connect the BNC connector on the other end of the cable to any of the Video In
ports on the back of the DVR.
STEP 3.
Plug one of the power leads on the power splitter (if your camera kit includes one)
into the power lead on the power and video cable. If you are connecting only a single
camera, connect the power lead to the power adapter and skip to Step 6, below.
