There are Dead Pixels in the HC-EPTZ cameras

December 06, 2022​

Overview:

Perform a system fix on the HC-EPTZ-NDI/USB camera to remove or reduce pixels found in dark areas of an image when Dynamic Range Control DRC is set to 0 (Zero). Using Packet Sender or the IR remote the following steps will be performed to reset the camera's image sensor and help resolve the issue.

Goals:

  • Reduce or eliminate pixels in the camera's image when DRC is set to 0 (Zero).

  • HC-EPTZ-NDI

    • Using a Packet Sender '' to send a Visca over IP commands to reset the camera's image sensor.

  • HC-EPTZ-USB

    • Using the IR remote to send a button key command to reset the camera's image sensor.

HC-EPTZ-NDI:​

NOTE: The following procedures will be using Packet Sender to send Visca commands over IP, and a computer on the same subnet as the HC-EPTZ-NDI camera.

  1. Connect HC-EPTZ-NDI camera to your network.

  2. Establish a connection to the HC-EPTZ-NDI camera using a computer on the same network. Note the camera's IP address.

  3. Verify that the camera has the latest Firmware available from HuddleCamHD.com .

  4. Open a live feed of the camera.

  5. Using the included IR remote navigate the On Screen Display (OSD) to Exposure > Manual > DRC Strength. Set DRC to 0. Close the OSD

  6. Using a soft cloth, cover the lens of the camera to completely blacken out the image.

  7. Open 'Packet Sender' and send the following command to the camera's IP address.

    1. Enter Camera's IP address in Address field.

    2. Enter the HEX: 81 0A 01 02 10 FF

      1. Select port TCP or UDP

        1. TCP Port = 5678 (recommended)

        2. UDP Port = 1259

    3. Press Send

  8. Wait for response 90 5x FF (Note: x value can be a changeable numeric value).

  9. Power cycle camera.

  10. Open the OSD > Exposure > and change to desired Exposure settings.

    1. Cover Lens of camera and verify the pixel difference when DRC is set to 0.

HC-EPTZ-USB:​

  1. Connect the HC-EPTZ-USB to a computer using the included USB3.0 A-B cable.

  2. Verify that the camera has the latest Firmware available from HuddleCamHD.com .

  3. Open a live feed of the camera.

  4. Using the included IR remote navigate the On Screen Display (OSD) to Exposure > Manual > DRC Strength. Set DRC to 0. Close the OSD

  5. Using a soft cloth, cover the lens of the camera to completely blacken out the image, leaving the Blue power light exposed. .

  6. With the lens covered and Blue power light exposed, use the remove and enter the following commands: [#] + [*] + [1] .

  7. After the upper left corner of the image prompts Doing Bad Pixel OK power cycle the camera.

  8. Open the OSD > Exposure > and change to desired Exposure settings.

    1. Cover Lens of camera and verify the pixel difference when DRC is set to 0.
