Oculus PRO Handbook Issue 3
Mounting the camera assembly is usually done by using the ¼ Whitworth tripod screw hole in the
attached bracket. A camera tripod will provide an adequate mounting for temporary use, or a
suitable mast and fixing screw can be erected to permanently mount the Oculus PRO several feet
above the ground. It is wise to mount the unit as high as possible, so that the effects of low-hanging
fog and dew are reduced, and stray light is minimised. It is also helpful if the camera is positioned
above a source of warmth, such as a house roof, to help keep the dew at bay.
The minimum setup requires only a USB cable to the monitoring computer. This should be as short
as is practical, but it will probably be necessary to have a fairly long lead if the Oculus PRO is
mounted high on a mast or roof. As the camera power is taken from the 12V supply, any long leads
should be as heavy as possible to reduce the internal resistance. The USB2.0 cable should be kept to
a minimum and if an extension is required, a high quality USB active extension cable should be used.
Depending on your setup, there is a possibility of earth loops due to the internal dew heaters
switching on and off. This may cause the USB communication side to be a little problematic and as
such, we have included a ferrite core which can be fitted to the USB cable to eradicate this affect. It
is very simple to install, simply wind the USB cable around the ferrite core. We recommend at least 3
time, but 4-6 times is best as shown. It is best to do this at the computer end as this will put less
pressure on the USB connector in the camera, prolonging the life of the camera.
