Introduction
General Description
The Discover Video Mantis is a live video encoder that provides live
streaming and recording from a variety of video input types. It is an
economical appliance that is ideal for IPTV, executive broadcasts,
morning announcements, enterprise and web streaming.
The Mantis appliance is compact and is used stand-alone on a desktop
or other surface, and a 6-channel rack shelf is available for high density
applications.

Configuration
Installation
Connect desired Audio/Video input, 10/100 Ethernet, and Power.
Power is supplied by an external AC power supply and connects to the
Mantis via a locking DC connector.
Video Input may be:
HDMI – Via HDMI connector (female)
SDI – Via BNC connector (female)
Component – Via Pr/Y/Pb BNC connectors (female)
Composite/CVBS – Via BNC connector (female)
DVI/VGA – via DVI connector, VGA via adaptor (female)
Audio Input may be digital (included with HDMI or SDI), or may be
analog via Left and Right RCA connectors (female).
Ethernet is standard 10/100 supporting IP V4.
RS-458 connecter is not currently used.

Find IP Address
Apply power and turn the front panel switch to the on position. Allow a
few minutes for the unit to boot up.
The Mantis is configured for DHCP and will obtain an IP address
automatically. To find the IP address used, insert a USB Flash Drive
into the USB connector and wait a few moments. Mantis will write a
file “IP.txt” which you may then open on a computer to read the IP
address. The USB must be formatted FAT16 or else the file may not
write properly.
You may also use the finder application to discover the IP address over
the network, or you may search your router’s DHCP table to find the IP
address used.
Configuration
Enter the IP address in a browser. When prompted, enter default
username and password:
Username: admin
Password: 000000
Setting
Set up the live streaming using the settings page:

Record
Mantis can record to a USB
device (including a high capacity
drive). To use recording, insert a
USB drive and check that it is
accepted and available on the
Record screen.
Enter a record name prefix. The
recorded file will begin with this
and will append a number plus
“.mp4”.
Click on the USB icon to view the
contents of the USB drive.
Click on the Network Drive icon to view the contents on the FTP server,
if FTP has been configured.
Configure FTP by entering the server, username, and password, then
select “Connect” to allow the Mantis to connect.
Check “File Upload After Record” to automatically upload the just-
recorded file after recording.
Check “Delete USB Files After Upload” to remove the just-uploaded file
after upload is complete (use this to preserve disk space on the USB
drive).
Record – Starts Recording. Changes to “Loading” as recording starts,
then changes to “Stop Record”. Select “Stop Record” to end the
recording. Copy progress will show “Finished” when upload is
complete if “Upload After Record” has been selected.

Operation & Notes
The Mantis does not deinterlace composite (CVBS) video. Some
devices, including iPhone6 (but not iPhone 5 or iPad) may not
display interlaced video. One work-around to this is to use
HDMI input with an external composite-to-HDMI converter.
When Mantis is set to HLS, the viewing URL is:
http://[username]:[password]@[IP]/hls/live.m3u8. You can view
this directly on most SmartPhones and Tablets.
When Mantis is set to RTMP, the viewing URL is:
rtmp://[IP]/live/Mantis (case sensitive). This can be viewed in the
Discover Video player, 3rd party players, and can be pulled in to
DEVOS via Advanced/Pull function.
When Mantis is set to RTSP, the viewing URL is:
rtsp://[IP:8000]/live (case sensitive). The port cannot be changed.
Mantis Encoder
When Mantis is set to RAW UDP, the stream can be viewed
using VLC player using udp://@[IP]:[Port].
If viewing directly from Mantis via HLS or RTMP, only one
simultaneous viewer is recommended (although several
simultaneous viewers may be possible).
To conduct Upload After Record, you must first connect to FTP
server by selecting the “connect” button.
After recording, you may select the USB icon to show all files on
the recording media. Right-click on a file to download it to your
computer. You can then edit the video, upload it DEVOS, Arcus,
etc.
Be sure to use a high capacity USB storage device, such as a
“Passport”, “Verbatum” or similar flash/disk device. Small
“Thumb Drives” will work, but recording video at high bit rate
creates large files and you will want to be sure you have enough
space! Storage device must be formatted for FAT32.
If Mantis becomes unresponsive, you can restore the product to
factory configuration by inserting USB with the reset code on it
and cycling the power. This software can be downloaded from
http://discovervideo.com/mantis

Mantis Shelf
The Mantis Shelf can mount up to six
Mantis encoders and provides power
supply and power distribution to the
encoders.
Install the encoders by securing them
with the included screws (two on top, two on the bottom).
Connect power using the included cables from the power distribution
box to each encoder.
Connect each Mantis to your network via Ethernet (you may find it
convenient to use an inexpensive Ethernet switch associated with each
shelf).
Note that it may be difficult to see the MAC address label once the
Mantis is mounted in the shelf. You should copy the MAC
addresses, or mark them on your own visible labels. The MAC
address help you identify each Mantis when using the Mantis IP
finder program.
Mantis Finder
Use the Mantis IP Finder to locate the Mantis encoders on your
network. The finder must be used on the same network as the
encoders. The discovered encoders will show their MAC addresses to
help you identify the Mantis.
