2.5 CAMERAS

CONNECTING CAMERAS

Your DVR uses BNC (British Naval Connector) 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.

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.
