Introduction
Sensoray's 4000 series of compact digital video recorders (DVRs) is targeted for
embedded OEM applications. The family currently includes models 4011, 4012 and 4013.
All of those record audio and video (A/V) to USB storage media and can capture JPEG
images on-the-fly without interrupting the recording. The units output live or recorded
video, or JPEG snapshots to an external composite monitor. Date and time are
maintained by a real-time clock with battery backup. Implementing a complete DVR
requires connecting power, a custom keypad or a keyboard, and a USB storage
device(s).
The DVRs encode standard NTSC/PAL composite video using efficient H.264
compression. Audio is digitized and compressed using AAC encoding. The compressed
A/V streams are multiplexed and recorded as MP4 or transport stream (.ts) files on a
user-supplied USB storage device, with file names automatically generated by the realtime clock. Videos and snapshots are saved to the /DCIM directory on the storage
device(s). Bit rates can be tailored to match application requirements and storage
capacity.
Models 4012 and 4013 include two incremental encoder interfaces, which allow position
information to be captured in real time and overlaid directly onto the video. The DVR
provides power to the encoders, 5 or 12V, selectable with a switch (model 4013) or a
jumper (model 4012). Each encoder's power line is protected by a 0.2A resettable fuse.
Various text overlays 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 DVR 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. Keypad switches functionality is
configured to match the control scheme of your custom keypad. If preferred, a standard
keyboard can be plugged into any of 3 available USB ports and used to control the DVR.
All members of the 4000 series use the same firmware. Some features are available on
particular models only. Connector pinouts are listed for each model in respective
chapters below. Differences between the models are summarized in Table 1.

Overlays
DVRs support a wide choice of text overlay information displayed on the preview,
recorded video, and screen shots. Overlay's position on the screen, font size and
background transparency can be adjusted.
The overlays are divided into primary and secondary overlay groups. One selection
from each group can be displayed on the screen at any time. Overlay transparency and
screen position can be set separately for each group.
Primary overlay
Primary overlay allows display of one selection of the following data:
1. Date/time
2. Encoder reading
3. Arbitrary text
Date and time display supports various formats. Encoder readings are converted into
length units (feet or meters). Up to five arbitrary text messages (up to 40 characters long)
can be stored and later selected for display, one at a time.
Secondary overlay
Secondary overlay allows display of one selection of the following data:
1. Title overlay
2. Coded overlay
3. Extra overlay
4. Additional overlay
Title overlay is an arbitrary text (32x14 characters) that could be entered and saved
to/loaded from a file on the internal or external storage device (parameters.txt).
Coded overlay allows assigning a 2-letter code to text messages and retrieving those for
display by typing in the code (a USB keyboard is required). Coded overlays are stored
in a file on the internal or external storage device (codes.txt). Codes and
corresponding messages could be entered using a standard USB keyboard connected to
the unit, or codes.txt file could be created on a computer and transferred to the USB
storage device. Codes are separated from messages with one or more spaces.
Page 16

Extra overlay is similar to Title overlay. It is an arbitrary text (32x14 characters) that
could be entered and saved to/loaded from a file on the internal or external storage
device (extra.txt). Additional overlay is similar to Extra overlay and is loaded from
addl.txt.

Page 24
24
Load system parameters
Loads system parameters from config.txt file.
Update firmware
This selection is available only 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 root directory of a USB drive. Update process usually
takes about 30 s, after which the board restarts. Please refer to "Firmware updates"
chapter for the details.
Update custom.zip
This selection is available if custom.zip file is detected in the root directory on one
of the connected storage devices. This file contains custom settings, such as a splash
screen and default system parameters.
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.
Custom default parameters
Custom default parameters (activated by selecting "Reset system parameters" from
"System information" menu) must be first saved to config.txt (using "Save
system parameters" from "System information" menu). The resulting config.txt
must be zipped into the root directory of custom.zip, and loaded using "Update
custom.zip" from "Setup" menu.
Turn WiFi On/Off
This selection is available only if the unit is programmed with WiFi-enabled
firmware and a WiFi adapter is detected in one of the USB ports. Please note that in
order to be detected by the DVR a WiFi adapter needs to be present at the power up.
Page 25
25
Turn WiFi ping on (available only when WiFi is turned on)
Enabling WiFi pings may help with some wireless clients (receiving devices) that
keep dropping the connection. Should be turned off normally.
Page 26
26
Firmware updates
Except for a few special cases updating the firmware is a straightforward procedure.
First, the firmware file is copied to the root directory of a storage device, the storage
device is then connected to the DVR. After that "Update firmware" selection appears in
the Setup menu. Selecting this option starts the process which takes about 30 seconds.
After that the unit automatically reboots.
The process maybe a bit more complicated when updating from a relatively old
firmware version to the new, WiFi-enabled firmware. Adding WiFi support to the
Sensoray’s family of DVRs resulted in a significantly different layout of the firmware.
Therefore the process of firmware update may be different when updating from an
older version without WiFi support to the version with WiFi support.
Update procedure:
1. Find out the current version of the firmware installed on your unit by going to Set-
up/System Information in the Menu.
2. Obtain the WiFi-enabled firmware file from Sensoray (s4011.fw, approximately 11 MB
in size). Please contact support at [email protected].
3. If the version of the firmware installed on your unit is 1660 or newer (version number is
greater or equal), skip to step 6.
4. Obtain a non-WiFi firmware file version 1660 or newer from Sensoray (s4011.fw,
approximately 6.5 MB in size) .
5. Copy non-WiFi firmware v.1660 or newer to the root directory of a USB drive, plug it
into your unit, and perform the firmware update procedure (Setup/Update firmware).
If the unit does not reboot for longer than 1 minute, cycle the power. If the pass-through
video is black, reset system parameters (Setup/System Information/Reset System Parameters). Make sure the firmware version now matches that of the firmware obtained
from Sensoray.
6. Copy WiFi-enabled firmware to the root directory of a USB drive replacing the previous
file, plug it into your unit, and perform the firmware update procedure (Setup/Update
firmware). If the unit does not reboot for longer than 1 minute, cycle the power. If the
pass-through video is black, reset system parameters (Setup/System Information/Reset
Page 27
27
System Parameters). Make sure the firmware version now matches that of the firmware
obtained from Sensoray.
7. The option “Turn WiFi on” should be now available in Setup menu section (if the WiFi
adapter is present).

Customizations
Keypad functions
The 4000 series DVRs allow creating custom keypad functions and layout. The process
is simple and takes 2 steps: assigning custom keypad functions and saving the custom
layout to the flash drive. After that the units are customized by loading the custom
mapping file. Once loaded the file does not have to be present on the flash drive.
Assigning custom keypad functions requires a USB keyboard to be connected to the
DVR. Press "K" key to start the process. For each pin of the keypad connector select the
corresponding signal name (DIO33V0, etc.), press Enter, and pick a desired function or
combination of functions from the list. Once the process is complete, save the custom
configuration to the file by going to Menu/Setup/System information/Save system
parameters. The configuration is save to custom.txt file in the root directory of the
flash drive. Note that all other settings are saved as well.
To load custom settings on another system connect the flash drive with custom.txt
file present on it, and select Menu/Setup/System information/Load system parameters.
Once the parameters are loaded the system no longer needs custom.txt file to be
present on the flash drive.
Splash screen
A custom splash screen can be created as described in "Update custom.zip" section of
"Menu system" chapter.
Maintaining custom settings
There are several ways of saving and restoring custom settings. Whenever any changes
have been made to the system settings, those could be saved by using "Save system
parameters" selection from "System information" submenu. The settings are saved to
config.txt file in the root directory of either internal or external drive (selected by
the user in case both drives are present). Those saved settings can be restored later by
using "Load system parameters" selection from "System information" submenu. It is
also possible to reset parameters to factory defaults by using "Reset system parameters"
selection from "System information" submenu.
Sometimes it may be preferable for "Reset system parameters" command to reset
parameters to custom defaults instead of factory defaults. That can be done using the

following procedure.
1. System parameters need to be changed, as desired.
2. Parameters need to be saved to config.txt using "Save system parameters".
3. config.txt needs to be placed into custom.zip file.
4. custom.zip must be loaded using "Update custom.zip" from "Setup" menu.
After that custom.zip no longer needs to be present on the flash drive, all the
settings are stored in the onboard non-volatile memory.

Wireless
All members of the 4000 DVR series support streaming video over the wireless network. This feature requires special WiFi enabled firmware to be programmed. Please
refer to "Firmware updates" chapter for the details.
To implement a network, plug in an approved USB WiFi adapter into one of the USB
ports and power up the unit. Once the DVR boots a WiFi network named “s4011” becomes available. Please note that the WiFi adapter has to be already plugged in when
the unit is powered up.
As with any wireless network, connection is handled by the operating system of the
connecting device. The “s4011” network is unsecured. Any device can connect to it
without a password and can connect either to the video stream directly, via RTSP, or
access the browser based interface.
WiFi adapters
Only devices qualified by Sensoray are guaranteed to work. Currently the following
products are recommended:
1. Anewish Mini WiFi adapter, available from https://www.amazon.com/ANEWISH-
Mini-Wifi-150Mbps-Raspberry/dp/B017N6KI8W, or similar
2. Similar adapters based on Ralink RT5730 chipset.
3. The Edimax EW-7811Un adapter. Available from
https://www.amazon.com/Edimax-EW-7811Un-150Mbps-RaspberrySupports/dp/B003MTTJOY.
4. The Lib-Link adapter with a large antenna for extended range up to 100 feet. Avail-
able from https://www.adafruit.com/product/1030.
Please note that availability may change.
Streaming video from a DVR
By using an RTSP client a video stream can be viewed on a mobile device or a computer. There are various free programs available from Google Play or iTunes to directly
view RTSP streams. Sensoray tested two of those: VLC
Page 31

(http://www.videolan.org/vlc/index.html) and RTSP Player (http://rtsp-
player.soft112.com).
Boot the 40xx with an approved WiFi adapter plugged in. Select "Turn WiFi on" in the
Settings menu. Wait for the adapter to turn on ("Turn WiFi off" menu selection will replace "Turn WiFi on").
Connect your mobile device or computer to the 40xx server wireless network ("s4011").
Select "Open network stream" option in your RTSP viewing application. Type the URI
rtsp://192.168.0.100:554/streamA.h264 into the location field of the applica-
tion. Please note that the URI is case sensitive.
The default stream is video only with no sound. Other streams are available: a list
streams can be found by connecting to the 40xx device with a browser using address
http://192.168.0.100/rtsp_streams.htm. A link you want can be copied and
pasted into your RTSP stream player.
