AVT GigE Cameras Installation Manual V1.1.0

Troubleshooting

• Linux only: Run as root, allowing the OS to boost the priority of the Allied

Vision driver thread, and the driver to bind directly to the NIC adapter.

Users who feel running as root compromises their system security may

find the following implementation satisfactory:

– Set the executable owner as root

– Set the “setuid” permission bit on the executable

– In code, when application starts use capset() to release all but these

privileges: CAP_SYS_NICE, CAP_NET_ADMIN, CAP_NET_BROADCAST,

CAP_NET_RAW. The application will start with all root privileges, but it

will drop them immediately after startup

Troubleshooting for Bigeye G cameras only (IOD mode)

If the camera can be detected but no images can be grabbed:

Verify the camera operation mode: Make sure the camera operates in

continuous mode, and not in IOD mode.

General description:

• Continuous mode: The camera generates the images with a constant

exposure time autonomously.

• Image on Demand (IOD): the camera produces no image until a trigger

impulse is generated.

Trigger mode Description

Continuous Off/Manual Freerun Camera generates images with a con-

stant exposure time autonomously. The

exposure time cannot be adjusted.

Continuous Off/Manual LineX/SyncInX Camera waits for an impulse at the

selected trigger input pin to start a

continuous image output.

IOD Off/Manual Freerun Camera produces images autonomously.

The exposure time can be adjusted.

IOD Off/Manual LineX/SyncInX Camera produces a single image for

every impulse at the selected trigger

input pin. The exposure time is defined

by ExposureTimeAbs/ExposureValue.

IOD Other/External LineX/SyncInX Camera produces a single image for

every impulse at the selected trigger

input pin. The pulse width defines the

exposure time.
