How far will a
wireless camera system transmit?
You should expect to be able to transmit 300 feet with the LD
system for barns. Under perfect conditions our LD long systems will
reach well over a mile. Your specific situation will determine
My barn is metal. Will
that affect a wireless camera system?
Yes. Radio frequency signals will not pass through metal. In order
to transmit from or to a metal building you will need to transmit
through a window or doorway. You can also use an antenna on the
exterior of the building to avoid the blockage. This needs to be
decided before ordering a system as most systems are not set up for
additional antennas. The LD long system includes antennas that are
placed outside the barn. We have a number of antenna choices for all
What will affect the
distance over which the system will transmit?
Transmission distances are estimated for line of sight (LOS)
situations. That means that the signals will transmit in the same
way that you see. If you can see it, the signals can transmit. While
the signals are not blocked by trees, sheetrock, wood siding etc.,
heavy tree growth will inhibit the transmission. In the spring, new
leaves can also affect the transmission distance due to the higher
absorption of young moist leaves. Often, setting the receiver so
that the signal can pass through glass (a window or glass door)
instead of passing through an outside wall will resolve the problem.
What is LOS and how does
it affect my system?
LOS refers to line of sight. RF transmissions travel in much the
same way as your sight. If your sight is blocked, the signals may be
blocked. In actual practice, RF signals are reflected or absorbed by
objects that they encounter. Hence signals are often reflected off
obstructions and “bounce” until they reach the receiver. That is why
we say that signals may be blocked. Often signals will travel to the
receiver even though you do not have a clear line of sight
How can I increase the
distance that my system will transmit?
The best way to increase distance is through the use of an antenna.
Antennas can be used at the transmitter, receiver or both. Use of a
separate antenna also allows it to be installed outside of a
building that may be causing an obstruction. Transmission range can
be increased to as much as 6,000 feet through the use of exterior
antennas. Power can also be increased but that is not as effective
as the use of an antenna and may require an FCC license.
Can I increase the power
output of my system?
Yes. This can be done through the use of a more powerful
transmitter or with a power amplifier. However, both of these
options will place the power of the unit outside of the limit
allowed under FCC part 15 requirements. The FCC requires a license
for systems at higher power levels.
What are the advantages of
color versus black and white systems?
Black and white systems are less expensive to purchase. Black and
white systems also operate at lower lux values -- meaning they will
produce pictures in lower light conditions than color systems. The
advantages of color systems are the enhanced viewing of details that
are apparent in color. There has been so much progress in the area
of CCD sensors that color competes directly with black & white for
low light clarity.
How difficult is the
system to install?
The systems are very easy to install. Installation is a matter of
plugging in color coded plugs. Trailer systems require the running
of a cable from the cameras to the front of the trailer. This is
generally done at the upper interior corner of the trailer wall or
under the trailer. For wireless trailer systems the cable is for
the antenna while for wired systems the cable is the complete video
and power cable. Both cables are around 1/4" thick
Can I use the cameras
Cameras that are designated as weatherproof or outdoor cameras can
be installed and used outside. Cameras not designated in this way
must be operated indoors. Our wireless cameras are rated at IP67
while our wired trailer cameras are rated at IP69K.
Can the system be expanded
at a later time?
The wireless systems for barns and trailers are expandable to a
maximum of 4 cameras. Wired trailer systems can expand to 3 cameras
in or on the trailer and a 4th camera on the truck as a hitch or
rear view camera.
What frequencies will
operate wireless camera systems?
Wireless cameras are available in 900 Mhz, 1.2Ghz and 2.4Ghz
frequencies. While all such frequencies are available the 900 MHz
and 1.2 GHz are limited and we recommend against using them in the
U.S. While these frequencies are in use around the world the U.S.
FCC reserves the 1.2 GHz and much of 900 MHz frequency for specific
uses and you can be fined for using these frequencies. As more
wireless products have come on the market additional frequencies
have been added. Systems that operate at 5.8 Ghz are now becoming
What are the advantages
and disadvantages of the different frequencies?
As the frequencies increase quality of transmission increases.
However, as frequencies increase accuracy of delivery becomes more
critical. While the higher frequencies offer higher quality,
reliable delivery of the signal may be compromised.
Are all cameras,
transmitters and receivers in a given frequency (such as 2.4Ghz)
No. Within each frequency there are channels or sub-frequencies.
For instance, in the 2.4Ghz frequency the 4 channels may be 2410,
2430, 2450, and 2470 Mhz. Equipment from another system or from
another manufacturer may operate at 2413, 2432, 2468, and 2490 Mhz.
For this reason, equipment must be coordinated for matching
frequencies. If in doubt, ask the supplier for the exact
Can I use more than one
receiver on a system?
Yes. The signals sent by the wireless transmitter can be received
by any number of receivers as long as one is not blocking the signal
of another. You can operate receivers in your bedroom, living room
and kitchen without problems.
Can I record to a VCR from
a wireless system?
Yes. The RCA plugs go into your television set are the same type
used in VCRs and DVD players and recorders. You can connect directly
to a VCR or DVD recorder to record transmissions. Similarly you can
record from the monitor in our trailer systems.
What is IR and why would I
IR is infrared and allows the camera to operate in total darkness.
Infrared light is invisible to people and animals but is “seen” by
the special infrared camera sensor. Infrared pictures are always in
black and white even if the camera shows color during daylight
How many cameras can I run
on one system?
The wireless barn and trailer systems can operate up to 4 cameras.
All that is necessary is that each camera be switched to a different
channel. Each camera can be viewed by switching the receiver to
each channel with the receiver channel button. Channels can also be
changed with the remote control or the receiver can be set to
sequence so that the receiver will automatically switch channels.
The receiver can be set to sequence to 2, 3, or 4 channels in
rotation depending on how many cameras you wish to view. These same
systems can also be set for manual channel changing.
Do I need a license to
operate a wireless camera system?
No. Our systems are approved under FCC part 15 regulations and no
license is required. If a special high power transmitter is ordered
or a power amplifier is used, the FCC requires licensing under part
90 of their regulations. It is the responsibility of the wireless
equipment operator to obtain the necessary licensing.
