Mounting
The TMC 3 can be mounted using the threaded holes in
the base to attach it a pole or similar structure.
It can be mounted in either orientation, with the camera
mounted below the antennas as shown on the left or with
the camera above the antennas as shown on the right.
In both of these scenarios it can be seen that the camera
is separated from the RF radiating antennas. This ensures
that there is no interference between the radio transmitter
and the camera’s video.
If the TMC 3 is to be mounted onto a flat surface where it is not possible to position the antennas
so that they hang below the camera it is important to position the antennas such that they do not
interfere with the camera’s view.
This is important not only to ensure that the video is not impaired by the physical antenna but also
to ensure separation between the camera’s video and the RF signal transmitting from the antennas.
The example shown on the right shows an improper setup, the
antenna’s position will interfere with the camera’s video.
It is therefore necessary to position the antennas at an angle
away from the camera’s field of view, as indicated.

The example shown here is a correct setup when the camera and
antennas are positioned in the same orientation. The antennas are
rotated to an angle that does not impair with the camera’s field of
view.
If possible the antennas should be positioned behind the primary
viewing pan angle, as shown here. This may not always be possible
if 360° of view is required but should be considered if the camera is
being used in a scenario where the main focus is within a 180° field
of view, such as a deployment at the side of a street.
