Installing the Camera
Cameras are suitable for
outdoor installation.
Installation in a sheltered
location is recommended.
For example, install under
shelter protected from the
elements, such as beneath
roof eaves. The diagram to
the right shows an example
of an ideal location for
outdoor placement.
Installation Tips & Warnings
• Aim the cameras to best optimize the viewing area:
select a location for the camera that provides a clear
view of the area you want to monitor.
• Install camera in an area that is free from dust, and
that is not in line-of-sight to a strong light source or
direct sunlight.
• Avoid installing the camera where there are thick
walls or obstructions between the camera and the
receiver.
• Avoid installing in a location which requires the
wireless signal to pass through cement, concrete,
and metal structures. This will reduce the range of
transmission. For details, s See “Appendix B:
Frequently Asked Questions” on page 14.
• Select a location for the camera that has an ambient
temperature between 14°F ~ 122°F (–10°C ~ 50°C).
• Not intended for submersion in water. For
outdoor use, installation in a sheltered location is
recommended.
Mounting Positions
You may mount your camera on a wall, ceiling, or
counter. See the images below for recommended
configurations of the camera stand and antenna.

3Screw the antenna to the back of the camera.
Use the included mounting screws to mount the
camera to the mounting surface:
• Mark the position of the screw holes on the wall.
• Drill holes and insert the drywall plugs (included)
as needed.
• Firmly attach the stand to the wall using the
provided screws.
Cable Notch
NOTE: Before you begin,
decide whether to run the
power cable through the wall /
ceiling (drilling required)
or along the wall / ceiling.
If you run the cable
along the wall / ceiling,
you must run it through the cable notch on
the base. This will keep the camera base flush to the
surface when mounted.

steps to pair up the camera and receiver.
To pair the camera to the receiver:
2
1Make sure that the camera and receiver are
both powered up.
On the receiver, press and hold the PAIRING
button for 5 seconds to activate the pairing
function.
• The on-screen displays informs you that you
have 30 seconds to press the pair button on the
camera.
3Press the black pair button on the back of the
camera. You must press the pair button on
the camera within 30 seconds of pressing the
PAIRING button on the wireless receiver.

Appendix B:
Frequently Asked Questions
What are the differences between wired
and wireless cameras?
Does a wireless camera require power?
How far can a wireless camera transmit
a video signal?
A wired camera has a video cable that transmits
the video signal from the camera to a recording or
viewing device.
A wireless camera does not use a video cable.
Instead, it wirelessly transmits the video signal to a
wireless receiver that is connected to your recording
or viewing device. Although the typical digital wireless
camera is priced slightly higher than a wired camera,
wireless cameras can provide cost savings compared
to standard wired setups. For example, wireless
cameras do not require cabling to be run between the
camera and the viewing / recording device, which
reduces installation time and cost.
Yes. Wireless cameras require two power sources: one
connected to the camera, and the other to the receiver.
In an open field (with line of sight), a typical wireless
camera has a range between 250 to 500ft. In a
closed environment—such as an interior of a house—
the wireless camera range is between 100 to 165ft
The signal range varies depending on the type of
building materials and/or objects the wireless signal
must pass through.
Cubical walls, drywall, glass, and windows generally
do not degrade wireless signal strength. Brick,
concrete floors, and walls degrade signal strength.
Trees that are in the line of sight of the wireless camera
and receiver may impact signal strength.
The signal range also depends on whether there are
competing signals using the same frequency as the
camera. For example, signals from cordless phones or
routers may affect signal strength.

ENGLISH
Are digital wireless camera signals secure?
Signal strength decreases as it passes through different
types of material. Try to position your wireless camera
and receiver in a location where the signal does not
pass through metal or concrete blocks, which can
significantly reduce signal strength (as shown in the
table below).
Material Signal Reduction (%)
Plaster & Wood 10 - 30%
Brick 30 - 50%
Concrete Cinder Blocks 50 - 70%
Metal & Metal Cladding 70 - 90%
NOTE: Signals that must pass through wet or moist
materials (e.g. shrubs and trees) may be significantly
reduced.
The stronger the signal strength, the higher the video
frame rate. The lower the signal strength, the lower the
video frame rate.
Yes. Lorex digital wireless products feature a wireless
transmission method called Frequency Hopping
Spread Spectrum (FHSS). This type of signal is highly
resistant to eavesdropping as it generates a channel
hopping sequence using an algorithm generated by
the receiver, which only the camera can follow through
the “pairing” function.
Pairing is an electronic handshake between digital
wireless devices. Digital wireless cameras can only be
paired to one receiver. This is to prevent interception
by third parties, and prevents any other device from
picking up the signal—this also means that you cannot
pair one camera to multiple receivers.
How many wireless cameras can I
install?
It is recommended to install a maximum of 4 wireless
cameras per system (4 receivers and 4 cameras).
Minimum space between receivers should be
2ft / 0.6m and minimum space between cameras
should be 6.5ft / 2m to minimize potential signal
strength degradation.

How many frames per second should I
expect from a digital wireless camera?
Current Lorex digital wireless cameras offer 10 - 30
FPS (Frames Per Second) performance. Actual frame
rate depends mainly on signal strength (see the chart
in section above).

Technical Specifications” on page 12.

Appendix C: Extending
Wireless Signal Range
DISCLAIMER: Certain accessories
are not available in all markets.
There are several ways to boost your wireless signal
as well as options to help you extend the range of the
wireless signal.
The digital wireless signal is virtually interference free.
However, you should always ensure there is a clear
line-of-sight between the camera and the receiver.
Clear Line-of-Sight
There should be little to no obstacles obstructing the
line-of-sight between the camera and the receiver. Solid
objects, such as concrete and metal, may limit the
range of the wireless signal.
Obstacles
Even with a clear line-of-sight between your camera(s)
and your receiver, you may experience a lower video
frame rate simply due to the distance between your
wireless devices.
Accessory antennas are available that can help extend
the range of your wireless signal.

Appendix D: Troubleshooting
Problem Solution
There is no picture
from the camera(s). • Make sure that the camera is plugged
into a power outlet and that the power
adapter is plugged in properly.
• Move the camera closer to the
receiver.
The picture is
dropping. • Move the camera closer to the
receiver.
• Try repositioning the camera, receiver,
or both to improve the reception.
The picture is or has
become choppy. • The picture may become choppy
when experiencing a lower frame rate
(e.g. 6 frames per second vs. a higher
20 frames per second).
• Try moving the camera closer to the
receiver.
• Remove obstructions between the
receiver and camera.
• Try switching to QVGA mode by
pressing the RESOLUTION button
on the receiver. Resolution will be
reduced, but video frame rate will
increase.
There is no audio
from the camera. • Make sure the RCA audio output
cable is connected to your DVR or
television audio input.
• Make sure audio recording is enabled
on your DVR. See your DVR manual
for further instruction.
The picture is white. • “Washout” or “white wash” can occur
when a strong light source is pointed
at the camera lens. The camera lens is
not harmed during a white wash.
• Do not point your camera towards a
bright light source.
The picture appears
fuzzy. • When viewing on a large-screen TV
or monitor (especially high-definition
televisions), the picture might seem
fuzzy as the camera is limited to VGA
resolution (640x480 pixels), while the
TV or monitor supports a much higher
resolution.
• For best performance, use with
TV PIP (Picture in Picture) function.
Check your TV product manual to see
if this feature is available on your TV.
The picture is
pixelated. • You may be in QVGA mode. Try
switching to VGA mode by pressing
the RESOLUTION button on the
receiver.
