View Full Version : Image missing while multiple camera connection

June 9, 2016, 09:03:10

I am using 5 cameras (DMK 23G618) in single CPU. When saving images with sequence timer in IC Capture, some of the camera skips to save image. I am using these all with single sensor trigger and machine speed is 200 parts per minute.

rest technical inputs are as follows:
Camera Model : DMK23G618
Sr. No.: 40510752, 40510754, 40510755, 40510756
Version of camera Driver:

Computer :
Processor: Intel(R) Core(TM) i5-4440 CPU@ 3.10GHz, RAM : 4GB, OS: Windows 7 - Professional, 32 Bit,
******bord: Gigabyte 81 series

Connectivity: INTEL PRO/1000 MT Desktop Adapter with D link Switch (Model No. : DGS-1008C)

Software: IC Capture 2.4

Procedure followed: We have conveyor machine all 5 cameras are at single point installed(4 from 4 sides, and 1 from top). Single trigger sensor is used to trigger all 5 cameras. Made individual folder for each camera to save images. When 500 parts passed through the station, 2 of the cameras having total saved images were 482 & 454.

we made trial for 10-12 times and every time any of 2-3 cameras facing this kind of problem.

Fps tried: all cameras with 120 fps / 60fps / 30 fps.


Please let me know any other detail required.
Kindly support to resolve this issue as two of our project with multiple cameras are on hold due to this.

Hello Sanjay

please always consider the GigE bandwidth, if you run multiple cameras. I am sure, you know that transporting more than 1 GBit/s is not possible through one network controller. Thus lower frame rates to at least 30 fps per camera. Another approach is to use a second network controller and switch.

The 23G camera model has no memory for image on board and therefore does not support packet resent. The successor DFK 33G618 has memory on board and supports packet resend. This reduces the frame drops extremely. Especially when triggered you can expect images. Over a certain time period this can be done, even if there is *not* enough bandwidth, until the memory of the camera is full.
