Getting Started
Follow the steps below to prepare your digital wireless
converter for installation:
2Attach antennas to the antenna jacks on the
receiver and transmitter.
1Identify the transmitter and receiver.
Termination cables are labelled Connect to
Camera on the transmitter and Connect to
DVR on the receiver.
Once you have completed the steps above, determine
which of the following installation options is best suited
to your needs.
Standard Setup:
Extension Cable Setup:
Television Viewing Setup:
Your camera is connected directly to the
transmitter, and the receiver is connected directly
to the DVR.
See “Standard Setup” on page 6 for the
standard setup procedure.
An extension cable (not included) is used to
connect your camera to the transmitter, and the
receiver is connected directly to the DVR.
Use this setup if you want to install the transmitter
far away from the camera for better reception. For
example, if your camera is installed at the back of
a barn and the signal strength is better at the front
of the barn.
You can purchase extension cables from
www.lorextechnology.com.
See “Extension Cable Setup” on page 8 for
the extension cable setup procedure.
The camera is connected directly to the transmitter,
and the receiver is connected directly to a
television (not included).
See “Television Viewing Setup” on page 10 for
the television viewing setup procedure.
NOTE: Video and audio recording are not
available through television viewing setup.

1Signal indicator:
The signal indicator shows the strength of the
signal being received from the transmitter. The
number of bars in the signal indicator shows
the strength of the signal. One or no bars
indicates the signal is poor. Four bars indicate
a very strong signal.
Status indicator:
The message “Out of Range“ appears if
the receiver cannot communicate with the
transmitter.
ATTENTION: If the signal is low (e.g. 1 or 2 bars) adjust
the antennas or reposition the transmitter and / or receiver
to improve signal strength.

Pairing the Transmitter
and Receiver
To pair the transmitter to the receiver:
2
1Make sure that the receiver and transmitter
are both powered up and all antennas are
properly attached.
Place the transmitter and the receiver within
1ft of each other. Press and hold the PAIR
button on the receiver for 3 seconds to activate
pairing mode.
• The indicator LED will flash on and off to
indicate that pairing mode is active.
3Press the PAIR button on the transmitter within
30 seconds of activating pairing mode. The
indicator LEDs on the receiver and transmitter
will glow steadily if pairing is successful.
The transmitter and receiver have already
been paired. If you have received a replacement
unit, OR if your transmitter and receiver are not paired
up, follow the steps below.

Frequently Asked Questions
What are the differences between wired
and wireless systems?
Does a wireless system require power?
How far can wireless video and audio
be transmitted?
A wired system has a video cable that transmits
the video signal from the camera to a recording or
viewing device.
A wireless system 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. Wireless systems do not require
cabling to be run between the camera and the viewing
/ recording device, which reduces installation time
and cost.
Yes. A typical wireless system requires two power
sources: one connected to the camera, and the other to
the receiver. The digital wireless converter requires a
third power source for the transmitter.
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.

16
Are digital wireless signals secure?
Signal strength decreases as it passes through
different types of material. Try to position your wireless
transmitter 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 transmitter can follow through
the “pairing” function.
Pairing is an electronic handshake between digital
wireless devices. Digital wireless transmitters 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 transmitter to multiple receivers.
How many digital wireless converters
can I install?
It is recommended to install a maximum of 4 wireless
converters per installation (4 receivers and 4
transmitters). Minimum space between receivers should
be 2ft / 0.6m to minimize potential signal strength
degradation.

Appendix C: Troubleshooting
Problem Solution
There is no picture
from the camera(s)
• Make sure that your camera is
plugged into a power outlet and
that the power adapter is plugged in
properly.
• Move the transmitter closer to the
receiver.
The picture is
dropping
• Move the transmitter closer to the
receiver.
• Try repositioning the transmitter,
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 transmitter closer to the
receiver.
• Remove obstructions between the
receiver and transmitter.
There is no audio
from the camera
• You must have an audio camera in
order to receive audio.
• Ensure your television / computer
speakers are not muted.
• 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 appears
fuzzy
• When viewing on a large-screen TV
or monitor (especially high-definition
televisions), the picture might seem
fuzzy as the system is limited to VGA
resolution (640x480), 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.
