Congratulations on your purchase of this PRO-CAM from Swann! You’ve chosen well: we think this is
one of the finest vari-focal CCTV video cameras available. The adjustable lens and on-screen menu
system make the PRO-CAM ideal for monitoring any kind of space in almost any lighting conditions...
even no light at all, as it can see up to 40m/130ft in complete darkness!
Our two cents: you’ve spent the money on a great camera. It’s worth spending a bit of time making
sure it’s set up right. This manual will take you through what you need to do to get the camera
delivering high quality images, and will let you know a little about how you can tweak it further.
The Process: An Overview
1. Choose a spot for your camera. This will be influenced by what you need to monitor, the places
nearby which could support a camera, the lighting conditions of the environment and so on.
2. Connect the camera to a monitor. We suggest connecting it directly to a monitor during setup,
and to your DVR (or other recording device) afterwards. Having a monitor on hand in the same
location as the camera is a real time saver during setup.
3. Set the zoom. This will set the viewing angle of the lens, which determines how much the camera
can see (page 3).
4. Set the focus. This will allow you to choose which parts of what the camera can see is in focus.
In actuality, you’ll probably go back and forth between steps 3 and 4 until you’re happy with the
image (page 3).
5. Connect the camera to your DVR (or other recording/monitoring device) - see page 4.
Choosing a Location
The PRO-CAM is very flexible, and can be installed practically anywhere. Some of the things you’ll
have to consider when choosing a location are:
• What you want to monitor, and where you’ll get the best view of it.
• How you’re going to connect the camera to your monitoring system.
• How to keep the camera out of harm’s way. Up high in protected corners is a good option.
Rules is Rules
Regardless of all the tweaking of the lens and image processing you do, there are a few immutable
things that are true for all cameras, CCTV or otherwise.
• The closer the camera is to what you want to see, the more detail you’re going to get. You can
make some alteration by tweaking the zoom, but there’s no substitute for proximity.
• Areas with varied lighting conditions are hard to view completely, with any camera. If the bright
bits are exposed correctly, then the shadows will “black out”. If the shadowy areas are exposed
correctly, then the bright bits will overexpose and “white out”. Aiming the camera at an evenly lit
area will always give the best results.
Adjusting Focus and Zoom
• To access the zoom and focus, remove the two protective caps from the rear of the camera by
unscrewing counter-clockwise.
• Use a flat-blade screwdriver to turn the exposed control rod. The zoom is located on the top left,
and focus on the lower right.
• Be sure to securely replace the protective caps after adjusting the zoom and focus, otherwise
the camera will no longer be weather-proof.

Adjusting the Lens
The zoom and focus controls are located on the
rear of the camera.
ZOOM: The left hand dial controls the level of
zoom. You can vary the viewing angle between
23° and 81°. This is an approximately 4x
(2.8mm-12mm) optical zoom, which operates
in a similar manner to the zoom on your digital
camera. Basically, zooming in makes everything
appear to be larger, at the expense of the
viewing area.
Check out the diagram to the left for a visual
representation of the zooming process.
The smaller viewing angle (marked 23°)
represents the camera’s view when “zoomed
in”, and the larger angle (81°) represents the
camera’s view when “zoomed out”.
You can set the zoom to either of these
extremities, or anywhere in between.
When you change the zoom, you’ll also
have to change the focus. Why? Lenses are
complicated, and all the bits are joined together.
Changing the zoom will also change the focus.
FOCUS: The right hand dial controls the focus.
Adjusting the focus control is kind of like trying
on a different pair of glasses - it can make sharp
things look blurry and blurry things look sharp.
It’s not quite magic, but it’s pretty close.
Basically, once you’ve set the zoom, twist the
focus knob until what you want to see doesn’t
look blurry anymore. If you can’t turn the knob
any more one way, go back the other.
You can only have so much in focus at once -
photographers refer to the size of the area in
focus as the “depth of field”.
The diagram to the right shows a couple of
different focusing options. The shaded areas
represent the depth of field. As you can see,
there is no hard edge, some things are “more”
in focus than others.
Note that this is for illustrative purposes only - there are many factors which contribute to depth of
field which vary from location to location.
A: The lens is at its widest, and focused on an
area relatively close to the camera. The depth of
field is quite large.
B: The lens at its widest with focus set to
“infinity”. Anything in the shaded section will
be in focus, and this focus extends to infinity
(that is, things in the far distance will also be in
focus). However, things in the distance might be
too small to see the detail you require.
C: The lens at its tightest, focused on an area
close to the camera. As you can see, the more
the lens is zoomed, the smaller the depth of
field becomes.
D: The lens at its tightest with focus further from
the camera. At this distance, the actual depth
of field is much larger, but it doesn’t extend to
infinity like it does when the lens is wide.
