4. Remember if you are installing on a day

when the weather is good the signal will be
good However, when it is raining heavily the
microwave signal will be absorbed by the rain
and reduce the distance. So always keep the
distance to a minimum and allow for the use of
additional directional antennas.

5. On some sites you may have other

RF equipment that can interfere with the
VideoMitters and reduce the range or cause
poor performance. The best solution for a site

like this is tting directional antennas as they

help “block” out the interference.

1. The signal will not go through hills. The

density of the hill and water it contains in the
soil absorbs the microwave signal.

2. The signal will go through branches of trees

but remember that microwave signals will be
attenuated greatly by water. Leaves and plants
are full of water so the distance is reduced. To

help, t the best directional antennas and/or

avoid the trees.

3. In modern buildings sometimes the structure

is lined with “FOIL”. This can reect or “ground”

the wireless signal. Avoid transmitting through
such “shields”. If wiring is not an option then
use the powerful directional antennas to help
or mount the Rx unit on the exterior of a
building in an ABS box.

When you are tting multiple pairs of

VideoMitters on the same site, it’s really
important to have some knowledge of good
installation practice of wireless devices.

When you are installing any transmission
device, it’s always good practice to keep it
a reasonable distance away from another
transmission devices. This is because the signal
from one could overwhelm the other leading to
poor performance of one or both devices. Poor
performance may result in intermittent loss of
signal or non operation.

The VideoMitters are actually “transceivers”
this means that the “transmitters” and the
“receivers” BOTH transmit and means you also
need to keep pairs of receivers a reasonable
distance from each other.

The standard antenna that the VideoMitters are
supplied with is called an “Omni-directional”
antenna, this means it transmits in “all”
directions. So when two transmitters are close
to each other they will be transmitting signals
at each other as well as the receiver which
is why you need to keep them spaced apart,
spacing of 1-2 metres is required between
each transmitting device.

Professional installers of wireless equipment
would always use “directional” antennas so
that one transmitter is aiming its signal directly
at its own receiver and therefore the signal
is far less likely to interfere with another
transmitter located near it.

So on sites with multiple pairs of video
transmitters, it is always recommended to
use directional antennas for a professional
installation.

The added benet of the directional antennas

is that they will also add increased range
making the whole system more reliable.

The VideoMitter has 20 channels so
theoretically 20 pairs can be used per site
however it is only recommended to use 4
pairs per site to minimise any chance of
cross interference.

Adding directional antennas means the
transmitters next to each other don’t overwhelm
each other with erroneous transmission.

Two transmitters close together with omni
directional antennas, the signal from each can
overwhelm each other. Try keeping them at
least 1-2 metres apart.

1 - 2m

Using directional antennas
means the VideoMitters can

be tted closer together.

Read these instructions

before using the MIT160 and

MIT170 as they contain vital

information...

Connections - TX/RX

Although identical in appearance each unit is
clearly marked on the face as:

TX - Transmitter RX - Receiver

The Transmitter unit has the following
connections

1. Video in connection via a phono socket

2. Audio in connection via a phono socket

3. Video loopthrough via a phono socket for

adding an extra monitor at the transmitter end

4. Audio loopthrough via a phono socket for

playing audio through a monitor or speakers at
the transmitter end

5. 2.1mm12v D.C. power connection

Both the transmitter and receiver are supplied
with a power supply unit (PSU). If alternative
PSUs are used, the PSU for the receiver needs
to be capable of supplying 12V D.C. @
260mA continuously. The transmitter needs a
PSU capable of supplying 12V D.C. @ 235mA
continuously. Please keep this in mind if you
are intending to share a PSU for both the TX
unit and your chosen CCTV camera. When
choosing any PSU for CCTV equipment ensure
that it is fully regulated or you risk damaging
the CCTV equipment. A good quality supply
such as the “AntiHum” series featured on page
14 is ideal.

Connecting the Video & Audio Powering the Units

Connect the video input feed to the yellow
video phono socket marked ‘To Camera’ (1)
on the Transmitter.

Connect the video output feed to the yellow
video phono socket marked ‘To DVR’ (3) on
the Receiver.

If using audio, use the white audio phono input
marked ‘To Camera’ (2) on the Transmitter.

Connect the audio output feed to the white
audio phono socket marked ‘To DVR’ (4) on
the Receiver.

A video/audio lead with phono connections
at both ends is supplied. You may need to t

the CON003 Phono to BNC converter to the
yellow phono connector if the video input feed

has a BNC connection. The video/audio lead

supplied is 125cm long. If you need to use
an alternative lead, remember that both video
and audio signals require both a signal AND
a ground connection to complete the circuit.
