1. Introduction
The NETmc Marine DVR is our latest one size fits all, modular, adaptable digital video recorder.
Bringing together over 20 years of experience and innovative digital video solutions to the offshore
survey and inspection sector, this product consolidates features to replace the DVRi, XOPs, 73fifty,
DVRiHD and Four264.
Supplied in its base configuration as a single channel, simple video recorder, the unit can be
upgraded in the field* to perform other functions as and when desired.
Functions such as – overlay, blackbox, multi video channel, clip recording, remote control, integrity
management control (Coabis etc), pipeline mode (EIVA control and compatibility) are available.
Understanding that some of these features may only be of use on certain projects, the features can
be rented for set durations and activated by a license code emailed out to the field.
*some features may require return to supplier upgrades depending when purchased

Green if more than 25% of the disk is free.
Orange if between 10% and 25% of the disk is free
Red if less than 10% of the disk is free.
To start the recording, simply click on the REC button.
When recording has started, the status indicator changes to “REC” instead of “IDLE”, the REC
button will become depressed and the minute counter will start to increment.
The image on the screen shows the video signal that is being input to the DVR.
Once the desired footage has been recorded, simply click on the STOP button to end recording.
At any point during the recording or preview, the image on the screen can be saved as a jpg file by
clicking the STILL button.
To resume logging, simply click the REC button again.
The system will automatically create a new file, automatically named as per the configuration in the
SETUP page.
If audio has been lost or disconnected from the system a warning will appear on screen.
After correcting the problem click on the red warning to re-enable audio and continue. If no audio is
required, no action needed.

In composite video input models, the system will auto detect PAL or NTSC. Due to the different
picture size and frame rates, a switch during recording will cause replay issues – so the system will
prompt the user to the format change with the a red warning message. Clicking on this message
gives the user to continue on and risk file replay issues – or stop/start the recorder so a new file is
started with the new format.
Pelicase units have push-button shortcuts to make the unit easier to operate while wearing gloves
or in a moving environment where using the trackerball / mouse is difficult.
These buttons control the base functions of record, stop, still image grab, clip start/stop
#
The overlay controls are also brought out to push-buttons, to clear screen, switch between saved
pages and bring up the text entry box (typrewriter)
All these push-buttons (overlay and control) are only active when the NETmc recording software is
the active software application.
The active application will have red shaded close (x) button in the top right corner. Clicking
anywhere on an application should bring it to being the active one.
These buttons
control the base
functions of
record, stop, still
image grab, clip
start/stop

If multi monitors are being used – it may be beneficial if one or more of the live video feeds be
detached from the main software app and moved around and resized.
If supported / enabled, the UnDock button will be visible on each live video frame
Clicking UnDock will pull the video out so it can be moved around independently

Hitting Esc key or closing the UnDocked window will put it back where it came from in the main app.
In the top left of the UnDocked video window is some information.
The Blue text tells you what channel and source its from and its aspect ratio
The linking icon is used to force the aspect ratio of the UnDocked video - - it might seem like a good
idea to stretch out the video to match your connected monitor – but it might be distorting the detail of
the image (making circles oval etc) – if it doubt – click the control in the corner and see the video
jump to its correct proportions

5. Software Settings
Click on the Setup icon to access the set-up page.
In the set-up page the user can select:
- ALWAYS ON TOP (if another window is opened it will always be behind, not covering, the
DVR software)
- ALLOW RESIZE (lets the user stretch or shrink the software to fit chosen monitor)
- ISSOLATE USER & REMOTE SETTINGS (keeps 2 sets of file names and paths in memory
– those get in the setup page by the user and those set remotely by 3rd party software e.g.
Coabis. Can be useful is switching between manual and remote control use)
- FULL-SCREEN MODE (makes the video image the full size of the monitor, with the record
controls floating on top – the option appears to have these floating controls disappear after a
time and come back when the mouse is moved. Can be useful when duplicating the screen
for distribution
- Operating mode (when licensed for multi channel – switches between single, quad and all
sources on screen)
- Selected source (there may be more channels available then the unit is licensed for – this
allows the selection of which sources to use)
- video quality (by experiment / customer specification)
- REC Duration (files are automatically cut into segments – this selects the size of segment)
- UNLIMITED (over rides the auto segment and creates one file – use with caution as big files
may not be playable !)
