The HD USB Camera is the bare board of the exploreHD Camera but without the waterproof housing. This
camera provides the same excellent image quality as the exploreHD but uses a specialized lens designed
to be more suited for above water applications. The camera can output H.264, MPEG, and YUY2 at
reduced frame-rates. Due to its low distortion and smooth frame-rate, this camera is ideal for computer
vision applications.

Operating Notes
DeepWater Exploration 4exploredeepwater.com
For long term operation, the camera may get hot (MAX Temp 70C). This is normal and not a cause for con-
cern. The processor has an auto thermal shut off if it does exceed normal operating temperatures. If you
are designing a custom mount, it can not be manufactured with Polylactic acid (PLA) plastic as the heat
from the camera will cause the plastic to weaken. Acrylonitrile butadiene styrene (ABS) is recommended
instead.
Temperature
The Sony IMX323 sensor used in this camera is chosen for its smaller footprint while still providing great
image quality. Typically, CMOS sensors contain a ceramic plate on the back to prevent incident light from
entering through the back of the sensor causing an X-ray effect. The IMX323 sensor does not have a
ceramic plate and is therefore susceptible to indent light from the back of the camera affecting image qual-
ity. This can easily be avoided by using our included camera holder or using black electrical tape to cover
the back of the camera PCB.
In order to ensure the sharpest image from your camera, the distance between the sensor and the lens
must be set correctly. Before the camera leaves our facility, the focus is set manually and a screw is placed
on the side of the lens holder to lock the distance. Sometimes, this screw can get loose over time and the
camera looses proper focus. You can adjust this manually by taking the screw off and twisting the lens
until the image is clear when viewing a far away distance on a computer.

Mount Installation
DeepWater Exploration 6exploredeepwater.com
In order to enable the mounting of this camera, two screw holes are located on the base of the
camera holder bracket. These 20mm apart M3 counter-bores should allow for the attaching of
the camera to any surface, provided two M3 threads or nuts 20mm apart may be made or placed
on the surface.
To begin the process of installing the HD USB Camera, ensure you have the
parts detailed in the contents section of this manual as well as a 2mm hex
Allen wrench or screwdriver(not included).
Tap or drill a hole for where you want to mount the camera, and attach the
camera holder bracket to the surface using the longer M3 screws.
After the securing of the camera holder bracket, place the square nuts within
the square indentation located on the bottom of the camera holder, and align
the holes of the camera holder with the lateral holes of the camera bracket
holder.
Begin screwing in both remaining screws on each side of the camera bracket
holder, and properly position the camera to the point of view you require for
your uses, and finish screwing in the screws.
Connect the provided USB cable to the camera using the USB connector
located at the top of the camera holder.

Connecting to a Windows OS
DeepWater Exploration 7exploredeepwater.com
This camera is plug and play for all operating systems. On Windows, simply plug the camera in
and you should see it under device manager.
For the best quality, make sure the camera
is set to 1080p 16:9 30fps. If you notice
flickering, you can change the frequency of
the flicker reduction
OBS allows you to finely adjust the camera
settings
You can use the camera with the built-in Windows app. The app provides a decent quality encoder and
will provide you a decent bit rate. The app automatically uses MPEG as the video format
If you plan on streaming with the camera or record with high bit rate, you can use Open Broadcaster

Please install gstreamer following this guide
https://gstreamer.freedesktop.org/documentation/installing/on-linux.html?gi-language=c
For Testing the Camera
To be able to use v4l2-ctl, run the command:
sudo apt-get install v4l-utils
List your video devices via the command:
Check which video device from the exploreHD USB Camera supports MJPG and YUYV
formats (In our case it was /dev/video0) with the following command:
To get more information about supported resolutions and fps, you can also run:
In our case the video device /dev/video0 is the one that supports MJPG and YUY2 so we will
be using that in the gstreamer commands that follow below.
MJPG Command
YUY2 Command
**NOTE: the width and height on the gstreamer commands can be changed as long as our camera
supports the resolution
v4l2-ctl --list-devices
v4l2-ctl -d /dev/video0 --list-formats
v4l2-ctl -d /dev/video0 --list-formats-ext

We recommend using a low resolution like 640 by 480 to test if the camera works on the raspberry pi
*The IP 127.0.0.1 is used if you are testing to send and receive on the same device. Change it to the IP of
the device that will be receiving it if you want to stream from one device to another.
*Note that the port number does not have 5000, it can be whatever works for you
