Introduction
Model 4012 is a compact di ital video recorder (DVR) desi ned for embedded OEM
applications. It records audio and video (A/V) to USB stora e media and can capture
JPEG ima es on-the-fly without interruptin recordin . Its outputs allow live video,
recorded A/V or JPEG snapshots to be displayed on an external monitor. Date and time
are maintained by a real-time clock with battery backup. To implement a complete DVR
simply connect power, your own custom keypad and a USB stora e device. Videos and
snapshots are saved to the DCIM directory, which is created if not present.
The board encodes standard NTSC/PAL composite video usin efficient H.264
compression. Audio from the on-board microphone is di itized and compressed usin
AAC encodin . The compressed A/V streams are multiplexed and recorded as MP4
files on a user-supplied USB stora e device, with file names automatically enerated by
the real-time clock. Bit rates can be tailored to match application requirements and
stora e capacity.
Two incremental encoder interfaces allow position information to be overlaid directly
onto the video. The 4012 provides power to the encoders, 5 or 12V, selectable with a
switch. Each encoder's power line is protected by a 0.2A resettable fuse.
Text overlays reflectin current date and time can be applied to appear in the recorded
video and preview.
An external USB stora e device is required for DVR operation. If desired, a second USB
stora e device may also be connected and the 4012 will simultaneously record to both
devices. A common application for this is recordin to a removable device while
creatin an archival copy on a non-removable device. USB connectors are located on
both sides of the board to facilitate connection to both removable and embedded
stora e devices.
The DVR user interface supports a user-supplied keypad workin in conjunction with
the board's flexible on-screen menu system. Each keypad connector pin can be routed
directly to any keypad switch and confi ured to match the control scheme of your
custom keypad. If preferred, a standard keyboard can be plu ed into any USB port
and used to control the DVR.

File management
Setup
Play video
Selectin “Play video” brin s the next menu level:
===Play video source===
Internal
External
Selections are displayed if internal and external stora e devices are present. If only one
is present, the files list is displayed. File selection is made usin arrow keys. Pressin
OK/Enter starts playback.
View snapshots
Behavior is similar to “Play video”.
File management
Selectin “File mana ement” brin s up the followin selections:
Copy video from internal
Copy video from external
Copy snapshots from internal
Copy snapshots from external
Delete files from internal
Delete files from external

Some of the choices may not be present dependin on the number of stora e devices
connected.
Setup
Selectin “Setup” brin s up the next menu level:
Set Date Time
Allows settin the battery backed-up real-time clock. The real-time clock is used to
automatically enerate file names for saved video files and snapshots. There is also an
option of havin the date/time text overlay present in recorded video and snapshots.
Record Storage Device
Allows selectin the recordin destination device(s): internal, external, both, or prompt
mode, in which the destination device has to be selected each time recordin is started.
Video
Brin s up Video setup menu:
==Setup Video==
Video Standard
Allows selectin between NTSC and PAL.
Interpolate
Turnin interpolation ON ets rid of motion artifacts at an expense of some
vertical resolution loss.
Video Bit Rate
Determines the compression level of recorded video. The hi her the bit rate, the
hi her is the quality, the more space is required on the stora e device.

devices with free space available. Allows savin system parameters to the flash drive,
restorin those from the flash drives, or resettin to default values. Parameters are
saved to confi .txt file to the root directory on the external flash drive. Loadin
parameters from file allows fast clonin of system settin s.
Update firmware
This selection is available only if a firmware file is detected in the root directory of one
of the connected stora e devices. Please obtain the firmware file s4011.fw from
Sensoray and copy it to a USB drive. Update process usually takes about 30 s, after
which the board restarts.
Update custom.zip
This selection is available if custom.zip file is detected in the root directory on one of
the connected stora e devices. Selectin it installs a custom splash screen. The splash
10

screen has to be created as a JPEG file with the name splash.jpg with one of the
followin resolutions: 720x480 for NTSC systems, or 720x576 for PAL systems. This file
has to be placed into the directory called images, and zipped to custom.zip. To
remove a custom splash screen place a zero byte custom.zip file into the root
directory of a stora e device and then select “Update custom.zip”. To create a zero
len th file in Windows open a command prompt window and type copy NUL /
custom.zip.
