Introduction
The 2MP HD MegaMitter can transmit a AHD CCTV camera wirelessly. Ensure the
camera connected has a 4-in-1 selectable output set to AHD or simply have a AHD
video output (2MP).
The MegaMitters are sold in pairs and one acts a transmitter and the other a receiver
for a one 2 one transmission.
Ensure the MegaMitters are installed in line of sight with no obstructions in between
the TX & RX. For greater distances you may need to consider upgrading the
antennas to directional ones which are sold as extras.
Up to 4 pairs of MegaMitters can be used on the same site but it is recommended to
use directional antennas when using multiple sets and keep them a minimum of 2m
apart. The MegaMitters are designed to work on 12V DC so they are easy to power
using standard 12V PSUs.

Connections & Powering
The MegaMitters need powering with a suitable regulated 12V DC power supply.
Both the TX and RX need powering individually. When they are powered up a red
power light will come on.
The Transmitter (TX) unit has the
following connections:
1. 2.1mm 12V DC Power in
connection
2. 2.1mm 12V D.C. power out
connection for power pass-through
so camera and TX can share 1
PSU.
3. Video in connection via a BNC
Lead.
The Receiver (RX) unit has the
following connections:
1. 2.1mm 12V D.C. power in
connection
2. Video out connection via a BNC
Lead
Both units have the following:
1. Antenna Connection (RP SMA Male
Socket) connects to extension
cables or direct connection antenna
models
2. Pair Button
3. Red Power Indicator LED
4. Green Link Indicator LED

Connecting Video
Connect the video input feed to the video BNC socket on the Transmitter.
Connect the video output feed to the BNC socket marked on the Receiver.
Both the transmitter and receiver require a power supply unit (PSU). The PSU for the
receiver and transmitter needs to be capable of supplying 12V D.C. @ 190mA
continuously.
Powering the Camera
To power the camera via power pass-through connect the power out cable (1) on the
transmitter to your camera’s power in female lead.
Note - If you press and hold the reset button by mistake you will need to re-pair the
units, see Pairing .

Antenna & Signal
The small antenna simply screws on to the top of the MegaMitters. Optional antennas
are available to increase transmission range.

Signal
Different site conditions will affect the signal and range of the MegaMitters.
1. Microwave signals will not go through
hills. The density of the hill and water it
contains in the soil absorbs the signal.
2. Microwave signals will go through
branches of trees but remember that they
will be attenuated greatly by water.
Vegetation is full of water so fi t the best
directional antennas and/or avoid the
trees.
3. In modern buildings sometimes the
structure is lined with “FOIL”. This can refl
ect or “ground” the wireless signal. Avoid
transmitting through such “shields”. If wiring
is not an option then try mounting the
receiver unit on the exterior of a building in
an ABS box.
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
microwave signals will be absorbed by the
rain and reduce the distance it travels.
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
transmission unit. The best solution for a
site like this is fi tting directional antennas
as they help “block” out the interference.

Pairing
Pairing
The MegaMitters are supplied tested and paired up. Only 1 receiver can receive
video from one transmitter, ensuring private secure connections. When both the TX &
RX are powered up and in within transmission range of each other the green light will
illuminate on them to indicate they are connected.
Pairing Process
1. Connect 12V DC Power to both Tx and Rx. Press the PAIR button down on
the RECEIVER for 3 seconds. The Link LED will start to flash.
2. A countdown will start for 30 seconds, then press and hold the PAIR button on
the TRANSMITTER until the link LED starts flashing.
3. Once pairing is complete both Link LEDs will display solid Green. If a monitor is
connected to the RECEIVER it will display a signal strength bar at the top left hand
corner of the display.
