View Full Version : video recording with external trigger

May 21, 2014, 15:24:01

I am using a DMK 21BU04 camera with Matlab+Image Acquisition toolbox and I would like to record movies using the external trigger to start the recording.

I tried using the TISIMAQ plugin but it only allows me to acquire 1 single frame with the external trigger.

What should I do to acquire images continuously using the external trigger ?

Thank you in advance.

The external trigger is intended to be used for single images only. However, the camera as a digital input. You check this input and start and stop recording to its setting.

For using the digital input of the camera, you need some extra electronics, because it is an Open Drain / Open Collection connection.

Alternatively: You generate trigger pulses as long as you want to capture an AVI file.
