NOTE: Before you begin, be sure that there are no live electrical cables in the area
you wish to mount the camera.
To mount the camera:
After connecting the camera as described on page 8 and installing the cables as
shown on page 9, place it in the desired location. Then, using an appropriate screw
for the surface you’re fi xing the dome to, screw the arm/bracket into place.
Ensure you have enough cable coming through the mounting arm/bracket to
connect it to your system. If you want to run the cables through a wall/ceiling, be
sure to drill a hole for the cable as well.
Placement Tips
For best results, carefully consider where you want to mount the dome. Whilst the
optimal placement solution will vary from application to application depending
on intent of installation, the environment of use and the lighting conditions
encountered there, there are a few points which are almost universal.
What you want to monitor:
The most obvious factor to consider when planning where to install your camera is
the question of what you wish to monitor, and how a movable PTZ system can be
incorporated into your specifi c environment.
• Ensure that the camera is located close enough to what you want to monitor
to capture the required details. For example, if you wish to capture the details
of a face, the camera should be located within a dozen feet (about 4m) of
the subject. This is also true if trying to read printed information - such as a
vehicle’s registration plate.
• Try to place the camera in a position that a potential security threat will fi nd it
diffi cult to avoid.
• A strategy which is often effective is to monitor entrances and exits - after all,
a security threat has to get in somewhere.
Mounting the Camera

Field of view
The PRO-690 can pan a full 360º. This means that (for example) installing the
PRO-690 in a tight corner is probably not an ideal utilization of its potential! A wall
is a better option, as it allows 180º of view for the camera. A freestanding pole
of suffi cient height and integrity to reliably hold the camera securely is an ideal
choice, as is the centre of the ceiling in a larger room or a warehouse.
Height
For best results, the PRO-690 PTZ Dome should be mounted as high up as
practicable. This is because the camera has complete freedom of tilt movement in
the 90º below the horizontal plane. Stated more simply, it can see things below it,
but not above!
Joining Cables
We strongly advise against the modifi cation (i.e. cutting and/or joining) of video
cables. Each cut/join will noticeably reduce video quality, and increase the chances
of the system failing over time. We also advise against using cable joiners/adaptors
to plug multiple cables together. Rather, we suggest using a single unmodifi ed
video cable, chosen in accordance with the guidelines below.
Recommended Cable Length and Type
Being a semi-professional PTZ dome system, the PRO-690 benefi ts greatly from
being installed using high quality cables to minimise video signal loss. This becomes
particularly important if using a cable longer than approximately 100ft/35m. The
longer the cable used to carry the video signal, the more noticeable the reduction
in video quality will become.
To maximise the quality of the video signal, consider using a high quality video
cable or installing your monitor/recording device closer to the PTZ dome. Of course,
in many circumstances, moving the monitor/recording device is not a viable option;
in these cases, a high quality cable is the best solution.
For optimal results, use a single, unbroken coaxial cable with a solid
copper core and copper braid shielding.
Exposure to Weather
The Pro-690 PTZ Dome is weather and water resistant (rated IP66). However, be
aware that long term exposure to adverse weather conditions (extreme temperature
fl uctuation, excessive moisture or direct sunlight) may eventually interfere with the
correct operation of the unit.
IMPORTANT: If mounting the camera outside, be sure to properly seal all
joints in the mounting arm/bracket using a silicon sealant. If this is not
fully sealed, water can enter the dome causing malfunction or failure.
