Firmware update on Zivid Two can in rare cases fail with timeout

Firmware update of Zivid Two camera can in very rare cases fail with the following error:

{quote}The firmware reported a timeout while updating the camera. Please power cycle the camera, restart the application, and try again.{quote}

Two Rev B2

The situation can be resolved by power-cycling the camera, restarting the application and doing FW upgrade again.

Zivid One+ camera can end up with a damaged projector if powered on for weeks before the first capture is triggered from the application

Failing to perform DLP projector mirror parking on a device can lead to the mirrors becoming stuck. The idle-state timer that parks the mirrors is started on every capture, but if the camera boots and sits idle for a long time this may never happen.

Capture time can be higher on Windows compared to Linux for identical hardware.

The difference is larger for low exposure times, and lower for higher exposure times. The relative difference between Windows and Linux on identical hardware is higher when using Zivid Two, compared to using Zivid One+.

Capture time on Windows can occasionally be longer (more than 1 second longer than normal)

Capture time on Windows can occasionally be longer (more than 1 second longer than normal) due to Ethernet packet loss leading to data re-transmits. We recommend to increase “Receive Buffers” and “Transmit Buffers” in the network driver settings in Windows to reduce the occurrence of packet loss.

Two Rev B2

Increase “Receive Buffers” and “Transmit Buffers” in the network driver settings in Windows to reduce the occurrence of packet loss.

“CameraImageTimeout” exception thrown during capture

On very rare occasions a “Command failed: CameraImageTimeout” exception may be thrown during capture.

This will resolve itself on the next capture.

Memory leak when creating Zivid::Application

When the Zivid::Application is created it allocates memory. All of this memory is not free’d when the object is destroyed. The leak can cause out of memory errors if you create many Zivid::Applications in the same process

Zivid Two may hang if the PC process is aborted mid-capture, leading to a reboot after 15 seconds.

Zivid Two may hang if the PC process is aborted mid-capture when there is also network congestion. Network congestion can typically occur when multiple cameras are connected on a 1G link.

Zivid Two will reboot after 15 seconds to recover from this state.

Two Rev B2

Avoid network congestion, and/or wait for the camera to reboot.
