Introduction
Model 4011 is a compact digital video recorder (DVR) designed for embedded OEM
applications. It records audio and video (A/V) to USB storage media and can capture
JPEG images on-the-fly without interrupting recording. 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 storage device. Videos and
snapshots are saved to the DCIM directory, which is created if not present.
The board encodes standard NTSC/PAL composite video using efficient H.264
compression. Audio from the onboard microphone is digitized and compressed using
AAC encoding. The compressed A/V streams are multiplexed and recorded as MP4
files on a user-supplied USB storage device, with file names automatically generated by
the real-time clock. Bit rates can be tailored to match application requirements and
storage capacity.
Text overlays reflecting current date and time can be applied to appear in the recorded
video and preview.
An external USB storage device is required for DVR operation. If desired, a second USB
storage device may also be connected and the 4011 will simultaneously record to both
devices. A common application for this is recording to a removable device while
creating 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
storage devices.
The DVR user interface supports a user-supplied keypad working in conjunction with
the board's flexible on-screen menu system. Each keypad connector pin can be routed
directly to any keypad switch and configured to match the control scheme of your
custom keypad. If preferred, a standard keyboard can be plugged into any USB port
and used to control the DVR.

File management
Setup
Play video
Selecting “Play video” brings the next menu level:
Play from internal
Play from external
in case both internal and external storage devices are present. If only one is present the
files list is displayed. File selection is made using arrow keys. Pressing OK/Enter starts
playback.
View snapshots
Behavior is similar to “Play video”.
File management
Selecting “File management” brings up the following selections:

Setup
Selecting “Setup” brings up the next menu level:
Set Date/Time
Allows setting the battery backed-up real-time clock. The real-time clock is used to
automatically generate file names for saved video files and snapshots. There is also an
option of having the date/time text overlay present in recorded video and snapshots.
Record Storage Device
Allows selecting the recording destination device(s): internal, external or both.
Video Standard
Allows selecting between NTSC and PAL.
Interpolate
Turning interpolation ON gets rid of motion artifacts at an expense of some vertical
resolution loss.
Video Bit Rate
Determines the compression level of recorded video. The higher the bit rate, the higher
is the quality, the more space is required on the storage device.
Audio Volume
Adjusts microphone sensitivity. The higher the value the louder recorded audio is.
Playback Seek
Adjusts the amount of time skipped when using Rewind and Fast Forward functions.
Overlays
Brings up an Overlay menu, see details below.
System Information
Displays various system information, including firmware version, detected storage
devices with free space available. Allows saving system parameters to the flash drive,
restoring those from the flash drives, or resetting to default values.
Update firmware (*)
This selection is available if a firmware file is detected in the root directory of one of the
connected storage 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 storage devices. Selecting it installs a custom splash screen. The splash
screen has to be created as a JPEG file with the name splash.jpg with one of the
following 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 storage device and then select “Update custom.zip”. To create a zero
length file in Windows open a command prompt window and type copy NUL /b
custom.zip.
