PVX16W Connections

The DWC-PVX16W multi-sensor panoramic camera houses four individual lenses that can be repositioned or replaced according to the user’s needs.

When encountering video loss or network discovery issues for this model, in addition to traditional IP camera troubleshooting, it is recommended to inspect the lens sensor modules when encountering such problems.

This article will outline troubleshooting in regard to lens sensor module installation for the DWC-PVX16W camera.

WARNING:  It is highly recommended that the MEGApix® Flex™ (DWC-PVX16W) be installed with four (4) lens modules.  Installing with only three (3) lens modules may compromise the camera’s operation overall.  For example, when upgrading a camera with only three (3) or fewer lens modules installed, the camera firmware will fail to install correctly.

**NOTE:  The Channel-1 Sensor Module Base Guide must have a Sensor Module installed for the camera to boot.

Supported/Affected Devices

  • DWC-PVX16W MEGApix® Flex™ 16MP Multi-Sensor IP Camera

Recommended Testing Materials

When bench testing the DWC-PVX16W, it is recommended to use the following:

  • The camera’s original PoE injector (DC12V, PoE+ IEEE 802.3at class 4)
  • Two (2) lengths of short patch cable
  • A laptop or computer for testing network communication
  • Star wrench for disassembling camera cover (provided with camera)

Troubleshooting Process

To bench test the DWC-PVX16W:

  1. Completely powered OFF the camera.

Using a patch cable, connect the camera to the PoE injector (PoE port).

Next, connect the PoE injector to your computer with another patch cable (LAN port).

  1. Using a star wrench (provided), remove the four (4) screws along the side of the dome then remove the cover to open the camera housing.

Disconnect all four (4) individual lens Sensor Module Blocks from their respective Base Guides.

**NOTE:  It is unnecessary to completely disassemble the Base Guide from the camera.  Unplugging the lens alone will be sufficient.

  1. Power ON the camera on through the PoE injector.

Connect first lens (Sensor Module Block-1) to the camera’s Channel-1 Base Guide.

    1. Use a computer to connect with the camera or locate it through its web client, ONVIF Device Manager, or with DW IP Finder™.

    1. Connect and test each lens separately by connecting each Sensor Module Block to the Channel-1 Base Guide to see if all lenses will individually capture video or if there is a hardware issue.

  1. If you are able to locate and stream video using each lens, proceed to the next step in this guide.

If you were unable to discover the camera on the network with any of the lenses, there may be an issue with the Channel-1 Base Guide of the camera.

If the discovery or display issue only occurred with a specific lens Sensor Module Block, there may be an issue with that particular part.

**NOTE:  If the DWC-PVX16W camera does not detect a Sensor Module Block connected to the Channel-1 Base Guide, it may not display video properly or may fail to boot. 

See the table in Step 5 to see how each Sensor Module Block is reliant on the Channel-1 Base Guide connection to operate.

  1. If all lenses displayed successfully when testing each separately, reconnect the lenses back to the camera.

If the camera ceases communication with your testing computer after reconnecting one of the lenses, see if the issue repeats by connecting a different lens to that same channel to confirm if the issue is lens related.

  1. If all lenses display without issue after reconnection, the issue may have been caused by an improperly connected lens.
