the playlist and video stream. If your router supports UPnP, remote access can be managed as described in the
section 5.6.2.
NOTE: if you make changes in the playlist configuration window, you also must download the updated playlist
file and import into the video player that you are using.
5.5 Recordings
Before using device video recording feature you must configure the storage where video records will be
stored. Then create a recording schedule.
5.5.1 Storage
Storage settings let you choose the type of storage between the USB and network drive. “Status” shows
mounting status of the drive. If the disk is mounted, the free disk space that will be used for recordings will be
displayed. If the USB option is selected, a list of available USB partitions will be displayed. See Figure 14.

Figure 14. Storage configuration.
If the storage type is a network drive, the “Network drive address” field must specify the full path to the drive.
Domain name is not supported in this field. The address must begin with // characters, followed by the IP
address. If the drive requires username and password add them to the appropriate fields. Otherwise, leave these
fields blank. Make sure the connection to the network drive is stable throughout the connection. Otherwise, the
recording process of the unit may deteriorate.
The “Keep records for” option specifies how long the records will be stored. They will be deleted automatically
after the specified time.
The device will create “records” folder in the storage and all records will be stored there. Switching the drives
between devices will automatically detect previously recorded TV programs.
5.5.2 Recording schedule
The schedule has two different options – one-time and weekly recording. Figure 15 shows both cases.
Figure 15. Recording schedule.
“One time recording” - means a single recording at the exact time and specified duration. The start time can
be selected up to 6 days in advance. Such schedule entry is shown in Figure 15 - “Polsat” record. If “One time
recording” checkbox is selected, the checkboxes indicating the days of the week will be ignored.
“Weekly recording” means that the TV channel will be recorded on each selected day of the week at the
selected start time. Such schedule entry is shown in the Figure 15 - “BBC World News” record.
To delete a scheduled record entry, just click the icon and confirm. If a video is being recorded at that
time, the current recording will end and be saved to a file.
5.5.3 Recorded TV programs
This section displays a list of recorded files. After the video has been recorded, it will be automatically added
to this list. M3U, DLNA playlist files in the streamer will be updated automatically.
Figure 16. Recorded TV programs.
Figure 16 shows two recorded video in the recorded video files list. Clicking the icon will download the
recorded file to the computer. Clicking the icon will erase the record from the storage.
5.6 IP parameters
Three submenu sections allow changing network related settings.

10
5.6.1 LAN
Figure 17. LAN IP parameters.
IP parameters can be set in this section as shown in Figure 17.
Selecting the “Enable DHCP client” checkbox will use a home router’s DHCP server to automatically assign
the IP settings (IP address, subnet mask, gateway, DNS server). Leave check box unchecked if you want to set
“IP address”, “Subnet mask”, “Gateway”, “DNS server” manually. Application will restart if IP address is changed.
“WEB port” is the port number of the control interface. Default value is 80. DO NOT change it unless you
really need having different WEB port number other than 80. If you accidentally change it and can no longer
access the control interface, use the “IP reset” feature by pressing and holding the Reset button on the device
back panel. Read section 6 for more information.
“Streaming port” is the port number of the streaming port. Full system restart is required if this port is
changed.
Device supports mDNS (Multicast DNS) protocol to access it at domain name instead of IP address. The
.local domain name extension is used for such domain names and is only available on the local network.
There are two domain names used to help you accessing the device WEB control interface.
“Unique local network DNS entry” is unique device domain name in the local network. You can access the
device using this unique address entry even if there are multiple steamers in the same network. Use the following
domain name:
http://<serial>.local
Where <serial> is the unit’s 16 symbols length serial number located on the label of the bottom device side.
You can see the example of such URL in the figure 17.
“User-specified local network DNS entry” – user assigned domain name for accessing the device WEB
control interface. Ensure that only one device exists in the same network with the same user specified local
network DNS entry. Otherwise accessing the WEB control interface by address http://iptv.local (or other user
assigned name) will not work.
Be sure to prefix the domain name with http:// as some browsers may simply redirect you to a search engine.
This protocol is supported by Windows and macOS, iOS. It is NOT supported on Android and Linux.
5.6.2 Remote access
Device supports UPnP router management so that the router can be configured to allow remote connections
just with a single click.

11
Figure 18. UPnP router management.
„Local port“ is the device internally used port.
„External port“ is a port number used to access the device remotely or receiving video streams.
“Streaming port” is a port number used for video streaming. External streaming port value should be equal to
local streaming port value. Otherwise “Terra TV” app or third-party video players may not work correctly.
„WEB port“ is the device control port number. Enable this port to access the device WEB interface remotely.
Also enable this port to use “Terra TV“ Android app remotely.
The “Debug port” can only be used if you have a problem and ask the Support for help to resolve it.
Otherwise, keep it off.
An “External IP address” is an IP address which can be used to access the device remotely. When you start
your device for the first time, it will try to set this address automatically (connection to the internet is required).
Also, after successful UPnP configuration, this IP address is read from the router. You can change this IP
address manually if you think the value displayed here is incorrect.
NOTE: use the following IP address template to access the device remotely:
http://<external_IP_adress>:<external_WEB_port>
When you click the “Update”, the device will try to enable / disable the selected ports on network router. The
status indicator icons will show the progress of the operation. Hovering over the status icon will display more
status information.
5.6.3 HTTPS
The user interface of the device can be accessed via the secure HTTPS protocol. Requirement for HTTPS:
• Device must have internet access to automatically renew the certificate;
• Device must be accessed using a domain URL (not IP address);
Domain name created for each device contains the unique serial number. See “HTTPS URL” in Figure 19.
Use this field’s value to access the device securely.
Figure 19. HTTPS configuration.
The domain name points to the local IP address of the device (it is not necessary to have a public IP
address). This secure access feature works even if DHCP client is used. As soon as device IP address is
changed, the DNS records of the domain name are changed automatically. An hour or more may be required for
updates of these records for your internet provider.
The SSL certificate is valid for 3 months and is automatically issued for the device domain and will be
renewed automatically. Default HTTPS port 443 is used for a secure connection, but can be changed by the user.

12
Domain can also point to the public IP address as well (see DNS type parameter in the Figure 19). Additional
router forwarding is required.
“Force redirection” flag will automatically redirect your WEB browser to a secure connection, even if you try to
access it using an IP address. Otherwise, secure connection link will be displayed on the login page for simpler
access.
NOTE: If the redirection fails for any reason (certificate expired, incorrect router forwarding, etc), forced
redirection can be disabled by adding a question mark after the URL. For example: http://192.168.1.10/?
5.7 System menu
This menu provides additional system parameters related to the system management. Depending on the user
access rights, some items in this menu may not be available.
5.7.1 Event logs
Various important events, errors, warnings will be displayed the system log (see Figure 20). Each record has
its own type that can be used to filter only certain messages.
Figure 20. Logs filtering.
Just check the “Logs filtering” checkboxes. Messages will be filtered automatically. The “Erase logs” button
will delete all logs from the system.
The “Download” button creates a logs.json file that can be used for troubleshooting and receiving help from
Support. Messages will be exported in English language regardless of the WEB interface language used.
