About the OSD

So - you’ve got one (or more!) of Swann’s range of PRO cameras, and you want

to use some of the advanced features. Good call! It may seem a little tricky at ﬁrst,

but it’s pretty easy once you’re up and running.

You can adjust almost any aspect of how the camera captures images. If you’ve got

experience in photography or video-making, then many of the camera’s functions

are things you’ll be familiar with.

If you don’t know much about cameras and optics, don’t worry - there’s nothing

you can do in the OSD which can actually damage the camera. If it does all go

wrong, you can use the Reset to Factory Default option to set everything back

to the default/automatic settings.

The RS485 Controller

Using the Quick Conﬁguration

The Quick Conﬁg button will give you instant access to the following settings:

1. DYNAMIC: Digital Wide Dynamic Range (DWDR) [page 10]

2. CONTRAST [page 14]

3. SHARPNESS [page 14]

4. BRIGHTNESS [page 9]

5. AUTO BW AT NIGHT: When disabled, the camera will attempt

to create color images at night. This can result in increased color

information at the cost of image quality.

• These settings are exactly the same as the ones in the Main Menu.

• Cycle through these settings by pressing the Quick Conﬁg button repeatedly.

• The Quick Adjust buttons will change the setting you’ve currently selected.

• To conﬁrm a change and exit the Quick Conﬁguration screen, click Save

Quick Conﬁg.

Connecting the OSD Controller

The two connections (RS485 and DC

12V) are located on the bottom of

the controller.

Use the supplied RS485 jack and

power splitter to connect the

controller. A complete connection

diagram is located on pages 4 - 5.

RS485 Port

Connection Guide

1. Connect the DC in plug on the

camera cable to the DC out pin

on the end of the extension cable.

2. Connect the BNC connector on

the camera cable to the BNC

connector on the extension cable.

3. Plug the green RS485 plug on

the end of the camera cable to

the RS485 port on the extension

cable. You may need to connect

the two wires to the RS485 plug.

(See insert, above right).

4. Plug the RS485 connector on the far end of the extension cable into the PTZ

controller. As with step 3, the plug may have to be connected to the wire

terminals.

5. Connect the BNC Output on the end of the extension cable to your video

monitoring/recording device (typically a DVR).

6. Connect one output from the power splitter to the DC in plug on the end of

the extension cable.

7. Connect the other output of the power splitter to the DC in plug on the OSD

controller.

8. Connect the power splitter’s DC in plug to the DC output jack on the power

adapter, and connect the power adapter to a wall socket.

Attaching the RS485 Plug

1. Using a small, ﬂat blade

screwdriver, loosen the two

screws.

2. Observing the adjacent diagram, insert the PURPLE/RED wire into the LEFT/

UPPER port, and tighten the screw so that it is held securely.

3. Repeat with the GREY/BLACK wire into the RIGHT/LOWER port.

Menu Structure

Setup (Main) Menu

Exposure: Controls how sensitive the camera will be to light. Press SELECT to

enter the Exposure sub-menu (page 9) to access the detailed exposure controls.

Note: As the cameras have ﬁxed iris lenses, control over exposure is determined

by the electronic shutter (that is, how long each frame is “exposed” for). Unlike

manually altering an iris, this setting will have no effect on your depth of ﬁeld (how

much of your image is in focus).

Special: Accesses the Special submenu, where many of the unique features of the

OSD can be found (such as options to set the camera’s on-screen Title, adjusting

the way the camera responds to Motion and allows you to access the detailed

Image Adjustment submenu). For more information, see the Special Menu section

on page 11.

White Balance: Controls how the camera interprets and displays colors. There are

a few settings, which are as follows:

AW1 (Automatic White Balance 1): The default setting, which will attempt to create

as neutral a white balance as possible. Colors tend to be slightly underexposed,

but represented quite accurately. The color of the light will have less of an effect

on how the camera perceives color.

AW2 (Automatic White Balance 2): The other automatic option for white balance

control. Rather than attempting to automatically correct for the hue of the light

(technically known as the “color temperature”) the camera attempts to accurately

represent what it can see as the human eye would perceive the same scenario. As

a result, images captured under daylight will seem slightly blue, whereas images

captured under artiﬁcial lighting will be tinted yellow (for tungsten ﬁlaments) or

green (for many ﬂuorescent tubes).

AWC --> SET: Allows you to create a custom white balance. You’ll need a sheet of

thick white card/paper. Hold the paper in front of the camera so that it covers just

over half the viewing area. If you are using a camera with a vari-focal lens (such as

the PRO-680/681) adjust the focus so that the piece of paper’s edge is sharp and

clear. Then, press SELECT. The camera will use the white card/paper to ascertain

the color of the light, and will adjust itself accordingly.

Manual: Click SELECT to open the Manual White Balance control menu. Here,

you’ll be able to have full control of how the camera determines color. For a

rundown of the Manual White Balance Control menu, see page 19.

Backlight: Controls what part of your images the camera will try and properly

represent, and how it responds to really bright lights.

OFF: The default setting. The camera will try and expose the whole scene evenly.

This may cause some areas to black out (under-expose) or white out (over-expose).

BLC (Backlight Compensation): The camera will try to expose things in the

foreground properly, even if this means that the background will over-expose/

white out. Press SELECT to open the BLC Menu, where you can ﬁne-tune how the

camera responds to backlighting.

HLC (Highlight Compensation): Places a black mask over extreme highlights in your

images. It can be useful to block out, for example, a bright window during the day

or car headlights at night. Press SELECT to open the HLC menu to control how and

when highlight masking will occur.

Reset: Possibly the most important menu item of them all! If you ﬁnd that the

camera is behaving strangely, then chances are something has been set amiss.

Setup Menu: Continued

From the EXPOSURE menu, you can control how the camera reacts to lighting

conditions.

SHUTTER: This setting controls the behaviour of the electronic shutter. In a

nutshell, it controls how long the camera will expose each frame. The longer that

the electronic shutter is “open”, the more light it will let in.

We recommend leaving this on AUTO (this will adjust the shutter speed

automatically). Only on rare occasions will AUTO not prove the best option -

however, these are so infrequent as to be almost unmentionable.

BRIGHTNESS: How light/dark the images coming from the camera will be. Unlike

the SHUTTER setting, this won’t affect how much light the camera needs to see to

create a high quality image. Rather, it affects how the camera processes the images

once they’ve been captured.

Increasing the BRIGHTNESS setting can be useful if you have an unusually dark

monitor/television, or are trying to view images in a very bright environment.

Typically, the default value is ﬁne unless you have speciﬁc problems you’re trying

to overcome.

AGC (Automatic Gain Control): Gain is a fancy term for amplifying a video

signal. It works in a similar way to amplifying music – the higher the gain, the

louder/brighter your images will be, but so will the background “noise” (in video

terms, “noise” refers to the random, grainy speckles that appear in images).

When should you decrease/increase the gain? Well, probably never. The MIDDLE

gain control is reliable and quite accurate. Only in the event of extremely unusual

lighting conditions or a very non-standard monitor/television should the automatic

gain control be adjusted.

Exposure Menu

DWDR (Digital Wide Dynamic Range) Menu

You can change and set the way that the camera captures and represents different

lighting conditions.

LEVEL: The higher you set the LEVEL, the more dynamic your images can be. It

works by changing how the camera interprets data from the CCD (the actual

image sensor). If this setting is low, then bright areas will have a tendency to

“white out” while shadows will do the opposite and “black out”. The higher you

set the DWDR, then the more the camera will attempt to compensate for this, and

you should get more detail in dynamic lighting scenarios.

In some cases, setting the DWDR Level too high can degrade the quality of your

images, as the camera may try overcompensating when it doesn’t need to.
