4. Choose Video Quality
Select Standard Quality or High Quality video recording. Standard quality video adds stronger
video compression hence optimizing recording capacity at the cost of video quality. When
selecting High Quality video the recorder will optimize video quality. When High Quality video is
selected, High Quality video shifts to Excellent Quality video when the frame rate is below 25/20
fps depending on the camera type. Thus ERT is reduced when shifting from 25/20 fps to 20/15
fps due to the higher video quality.
To expand the recording capacity it is possible to reduce the cameras native picture size.
Depending on the camera type, select HD1080, HD720, VGA or QVGA resolution from the dropdown box Picture Size.
Note: In Dual-Cam recordings, the maximum allowed resolution for the cameras are VGA. If
a HD camera is used in a Dual-Cam recording, the resolution is automatically reduced

4.6 Network Settings
Getting Oculus to work on a network requires two steps. The first step is to set up Oculus’
network configuration and the second step is to configure the PC and establish a remote
connection to Oculus. Before using Oculus® on a public network, i.e. the Internet, please
consider the network security.
31
Oculus® User Guide
Network Security
If Oculus® is connected to a public network the only thing that protects against unauthorized
access is when Secure Recorder is enabled. Please see section 4.1 on how to secure Oculus®.
Basically, anyone with access to the Oculus® Utility software can access an Oculus® if they know
the IP address, port number and server/client settings.
Note: To protect against unauthorized access when Oculus® is connected to a public
network, e.g. the Internet, it is strongly recommended that Secure Recorder is
enabled.
Note: When using the Network Adaptor to connect remotely to Oculus®, it is strongly
recommended that Oculus® is switched to Armed Mode. Please see section 4.5
about Armed Mode.
32
Oculus® User Guide
Network Configuration
To set the Oculus® network configuration click Change Settings…
Two types of configuration modes exist; DHCP and Static. In DHCP mode, Oculus®
automatically obtains the network configuration. In Static mode, the following settings must be
set up manually.
IP Address:
Oculus’ IP address on the network
Submask:
Submask of the network
Gateway:
Gateway of the network
Note: When DHCP mode is selected, it must be supported by the network for Oculus® to
obtain the network configuration automatically.
Server/Client Settings
The server/client settings determine who should try to connect to whom on the network.
Client:
Oculus® tries to connect to a remote host server
Server:
Oculus® is waiting for a remote client to connect
In Client mode, Oculus® will try to establish a connection on Port no to a remote host with the
IP address set in Server IP.
In Server mode, Oculus® will listen for incoming connections on the port set by Port no; no
Server IP address needs to be set.
Note: It is recommended to use a port number above 1023 as port numbers in the range 0
– 1023 are often used by other communication protocols.
33
Oculus® User Guide
Encryption
Choose between Disabled, AES-128 bit or AES-256 bit encryption.
Note: It is not possible to set your own encryption key but Oculus® will automatically
generate a random encryption key each time a new connection is established.
Connect to Remote Oculus
To establish a connection to Oculus from the PC, you must choose between Connect to Server
or Wait for Client. The setting on the PC must match the Oculus settings for the two to be able
to make a network connection. If Oculus® is Server, the PC must Connect to Server and vise
versa.
Connect to Server:
PC tries to connect to Oculus®
Wait for Client:
PC is waiting for a remote client to connect
When Connect to Server is chosen, the PC will try to establish a connection on Port no to
Oculus® with the IP address set in IP Address. The port no and IP address must match the
settings in Oculus® for the two to be able to make a network connection.
If the PC is Waiting for Client, only the port no needs to be set.
Click Connect to connect to remote Oculus and Disconnect to disconnect from Oculus®. The
current state of the connection is shown after Status.
Note: If the connection to Oculus® is done over the Internet, you most likely need to setup
port forwarding in router to which Oculus® is connected. The port no used for the
connection must be forwarded to the IP address of Oculus®. Please refer to the
user guide of your router.
Note: If the Oculus® is connected to the Internet via the mobile network using a 3G
router/modem, the Internet Service Provider (ISP) often assigns a private IP
address to the router. If that is the case, it is not possible to make a connection to
Oculus® when configured as server. Please configure Oculus® as a client or contact
your ISP to get a public IP address.
