If the device is accessible from the remote network you will see a playlist link with an external IP address in
the next configuration interface table as shown in figure 8. Make sure your router is set up properly to access the
playlist and video stream. If your router supports UPnP remote access can be managed as described in section
5.5.2.
NOTE: if you make changes in the playlist configuration window, you also must download the updated playlist
file and import it into the video player that you are using.
5.4 Recordings
Before using the device video recording feature you must configure the storage where video records will be
stored. Then create a record schedule.
5.4.1 Storage
Storage settings let you choose the type of storage between the USB and network drive. “Status” shows the
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 9.
Figure 9. Storage configuration.
If the storage type is a network drive, the “Network drive address” field must specify the full path to the drive.
The domain name is not supported in this field. The address must begin with // characters, followed by the IP
address. If the drive requires a 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 a “records” folder in the storage and all records will be stored there. Switching drives
between devices will automatically detect previously recorded TV programs.
5.4.2 Recording schedule
The schedule has two different options – one-time and weekly recording. Figure 10 shows both cases.

7
Figure 10. 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 10 on the “Friday movie” record. If
the “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 Figure 17 on the “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.
5.4.3 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 11. Recorded TV programs.
Figure 11 shows a 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.
5.5 IP parameters
Three submenu sections allow changing network-related settings.
5.5.1 LAN

8
Figure 12. LAN IP parameters.
IP parameters can be set in this section as shown in Figure 12.
Selecting the “Enable DHCP client” check box will use a home router’s DHCP server to automatically assign
the IP settings (IP address, subnet mask, gateway, DNS server). Leave the check box unchecked if you want to
set “IP address”, “Subnet mask”, “Gateway”, “DNS server” manually. The application will restart if the IP address
is changed.
“WEB port” is the port number of the control interface. The default value is 80. DO NOT change it unless you
really need to have a 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. A full system restart is required if this port is
changed.
The device supports the mDNS (Multicast DNS) protocol to access it at the domain name instead of the 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 access the device WEB control interface.
“Unique local network DNS entry” is the 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 a URL in figure 12.
“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.
5.5.2 Remote access
The device supports UPnP router management so that the router can be configured to allow remote
connections just with a single click.
Figure 13. UPnP router management.
“Local port“ is the device internally used port.
“External port“ is a port number used to access the device remotely or receive video streams.
“Streaming port” is a port number used for video streaming. The external streaming port value should be
equal to the 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 the “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 that 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 (a 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>

9
When you click the “Update”, the device will try to enable / disable the selected ports on the network router.
The status indicator icons will show the progress of the operation. Hovering over the status icon will display more
status information.
5.5.3 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);
The domain name created for each device contains the unique serial number. See “HTTPS URL” in Figure
14. Use this field’s value to access the device securely.
Figure 14. 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 the DHCP client is used. As soon as the 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.
The domain can also point to the public IP address as well (see DNS type parameter in Figure 14). Additional
router forwarding is required.
The “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, a 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/?
5.6 System menu
This menu provides additional system parameters related to system management. Depending on the user
access rights, some items in this menu may not be available.
5.6.1 Event logs
Various important events, errors, warnings will be displayed in the system log (see Figure 15). Each record
has its own type that can be used to filter only certain messages.
Figure 15. Logs filtering.
Just check the “Logs filtering” checkboxes. Messages will be filtered automatically. The “Erase logs” button
will delete all logs from the system.

10
The “Download” button creates a logs.json file that can be used for troubleshooting and receiving help from
Support. Messages will be exported in the English language regardless of the WEB interface language used.

settings will be restored to their default values, and all logs will be deleted.
5.6.10 Language, country
When you click the “Language, country” submenu, a pop-up window as shown in Figure 2 will appear,
prompting you to select the language, country, and region where your device is located. Incorrect country
selection can affect the time zone and other important settings. Make sure this setting is set correctly. DST
means that the time zone contains winter and summertime, which will be selected automatically according to the
country that you chose. In the future, governments may change the time-reversal rules, or the time zone of the
region. Inform the manufacturer of this device if the time zone information is incorrect.
5.6.11 Date, time
It’s important that the device has the correct time selected. Recording schedules is affected by the system
time. Figure 25 shows the two NTP servers as a date / time source.

13
Figure 25. Date and time settings.
”Local Time” shows the time of the device that it currently has, estimating possible DST offset. If the time in
this field is not correct, make sure you select the correct country (see section 5.6.10). Date and Time Source has
two options: NTP Server and Manual Input. In case of an NTP server, at least one server URL must be specified.
Make sure the IP settings (section 5.5.1) are correct and the device can access the NTP server. After clicking
“Update”, the device will try to connect to the server and update the local system time. The device will
synchronize the time automatically later on.
The “Manual input” option can be used for testing only, because it will never be synchronized to any external
time source and the time will be reset if the power supply will be disconnected.
5.6.12 Device information
Information about the device is shown in this submenu table (see Figure 26). You can check the software
version, time and other useful information about the system.
Figure 26. Device information.
6. Reset button
The reset button has different functions which mainly depend on the duration of the press.
• Device reset
A short press (less than 2 seconds) will restart the entire system. Red-green LED indicates acceptance of this
command. This corresponds to section 5.6.7 “Restart the device - Full restart“ function.
• IP reset
Pressing the button for 2-5 seconds will activate the IP reset function. A flashing red-green LED will indicate an
activated IP reset command. It will enable the DHCP option (device IP address will be assigned by the network
router) or set the address to 192.168.1.10 if the router does not exist. WEB interface port will reset to the default
value 80. A full reboot of the device will then be performed.
• Restore defaults
Pressing the button for longer than 7 seconds will activate the “Restore defaults“ function. Red blinking LED will
indicate an activated command. After releasing the button, all device parameters will be restored to their default
values, and the application will be restarted. IP settings will not be restored to defaults.
