PTZ Controls
You can bring up the PTZ Setup window by pressing the PTZ button on the remote
control, or by right-clicking the mouse in the live view mode, and choosing PTZ.
Note: the features which will usable depend on the capabilities and
limitations of your PTZ system.
Here, you'll be able to aim the camera, as well as alter aspects of the lens and iris
confi guration. We'll explain a little more about what each of these does:
1. SPEED ADJUSTMENT
By selecting this with the mouse or the
arrow buttons, you are able to change
the speed at which your camera will tilt,
pan and zoom. The higher the number,
the faster the camera will move.
2. ARROW BUTTONS
Used to manually move the camera. The
arrow buttons will move the camera in
the selected direction, and the centre
button toggles Auto-Scan ON and OFF.
3. ZOOM
If you are using a variable zoom PTZ
camera, you can zoom in or out here.
Zooming in will increase the size of
objects in view, at the expense of
reducing the fi eld of view. You may
need to adjust focus when using the
ZOOM function.
Remember: After making changes to the settings press/click the APPLY button.

4. FOCUS
Adjusts the focal plane of the lens.
If an image is blurry, try adjusting the
focus. To best set the focus, move one
direction until things become clear, and
then blurry again. Move back and forth
until you fi nd sharp focus.
5. IRIS
Controls how much light gets into the
camera. If things look too bright (or
white) lower the IRIS value. If things are
too dark (or black) raise the IRIS value.
Many cameras do this automatically.
6. CRUISE SET
Open the CRUISE SETUP window, see
next page.
7.EXIT
Leaves the PTZ SETUP menu.
MEDIA PORT: This is the port that the DVR will use to send information through.
The most important things are that:
1. Nothing else share this port. The default port number is 9000, which is not
used by many other devices/programs. However, particularly if you have
another DVR or DVR-like device, something might be using this port already. If
3
this is the case, change this value to be unique.
4 2. That this port is forwarded from your router to the DVR (this process is
called Port Forwarding). Check out or website (www.swannsecurity.com) for
5 supporting information and an online guide which covers port forwarding
for various popular routers/gateways. Forwarding a port is something like
opening up a fast-lane for network traffi c to get to and from your DVR - it will
7
signifi cantly speed up the fl ow to and from the DVR stopping 'traffi c jams'
which can prevent the DVR operating correctly via the network.
WEB PORT: This is the port through which you will be able to communicate with
the DVR. Like the Media Port, it will need to be forwarded properly in order to
ensure smooth, latency-free communication.
IP ADDRESS: Just as houses and businesses need to have an address which
identifi es their location on the road network, so too do computers and other
devices need addresses (called IP ADDRESSES) to identify their position on the
electronic network. The DVR uses IPv4 addressing, which consists of four groups
of numbers between 0 and 255, separated by periods. For example, a typical IP
address might be "192.168.1.24" or something similar. The most important thing
when setting the IP address is that nothing else on your network shares that IP
address.
SUBNET MASK: If the IP address is like a street address, then a subnetwork is like
your neighborhood. This will be formatted in a similar way to the IP address (ie. four
numbers up to 255 separated by periods) but contain very different numbers. In the
above example, the Subnet Mask might be something like: "255.255.255.0".
GATEWAY: This is the address of the "way to the Internet" - to continue the road
analogy, this is like your local access point to the highway. This is an IP address
in the same format as the others, and is typically very similar to the IP address
of the DVR. To continue the above examples, it might be something such as:
"192.168.1.254".
DNS: A "Domain Name Server". Everything on the Internet is located via an
IP address - however, for ease of use, we associate domain names (such as
"www.exampledomainname.com") with those IP addresses. This index is stored in
many locations online, and we call those locations DNS servers.
Remember: After making changes to the settings press/click the APPLY button.
