DW 072321 HD USB Camera

Introduction

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

Temperature
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.

Sensor Affected by Incident Light
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.

Lens Focusing
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

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

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.

Streaming Via Linux

Please install gstreamer following this guide
https://gstreamer.freedesktop.org/documentation/installing/on-linux.html?gi- language=c

• STEP 1
  To be able to use v4l2-ctl, run the command:
  sudo apt-get install v4l-utils

• STEP 2
  List your video devices via the command:
  v4l2-ctl –list-devices

• STEP 3
  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:
  v4l2-ctl -d /dev/video0 –list-formats
  To get more information about supported resolutions and fps, you can also run:
  v4l2-ctl -d /dev/video0 –list-formats-ext

• For Testing the Camera
  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.
  **NOTE: the width and height on the gstreamer commands can be changed as long as our camera supports the resolution

  • MJPG Command
    gst-launch-1.0 -v v4l2src device=/dev/video0 ! image/jpeg,width=1920,height=1080 ! jpegdec ! xvimagesink

  • YUY2 Command
    gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-raw,width=640,height=480 ! videoconvert ! autovideosink

• For Testing the Camera on a Pi
  We recommend using a low resolution like 640 by 480 to test if the camera works on the raspberry pi
  gst-launch-1.0 -v v4l2src device=/dev/video0 ! image/jpeg,width=640,height=480 ! jpegdec ! videoconvert ! ximagesink gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-raw,width=640,height=480 ! videoconvert ! ximagesink

• Testing Streaming Camera (use two different terminal tabs/windows)

• 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

  • To Send the Stream (same on Raspberry Pi):
    gst-launch-1.0 -v v4l2src device=/dev/video0 ! image/jpeg,width=1920,height=1080 ! rtpjpegpay ! udpsink host=127.0.0.1 port=5000

  • To Receive the Stream (run this command first):
    gst-launch-1.0 -v udpsrc port=5000 ! application/x-rtp, media=video, clock- rate=90000, encoding-name= JPEG, payload=26 ! rtpjpegdepay ! jpegdec ! xvimagesink sync=0

  • For Raspberry Pi:
    gst-launch-1.0 -v udpsrc port=5000 ! application/x-rtp, media=video, clock- rate=90000, encoding-name= JPEG, payload=26 ! rtpjpegdepay ! jpegdec ! videoconvert ! ximagesink sync=0
