Congratulations on your purchase of this PRO-780 from ! You’ve chosen well: we think this is Swann

one of the ﬁnest vari-focal CCTV video cameras available. The adjustable lens and on-screen menu

system make the PRO-780 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-780 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.

• That “image enhancement” stuff that they do on CSI 24 or is all lies. You can’t zoom in

indeﬁnitely on a video image. Licence plates are only readable from a few meters (a dozen or so

feet) away. If someone’s head is represented by three pixels, that’s it. Sorry. This is technology, not

magic. This is a CCTV camera, but it’s still just a video camera - it can’t see much better great that

than you can! Still, it does make for good television.

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.

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 3x 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. Lenses are complicated, Why?

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.
