View Full Version : external trigger for cameras

March 6, 2006, 17:05:06
Hi everyone,

I am kind of new to this so please be gentle

We have just bought 5 x DFK 21BF04 cameras that we need to synchronise. I know they take an external trigger but dont know how to supply one. Do I need something like a DIO card?

I'm assuming I need this because when I grab from 5 cameras simultaneously the video streams are offset ie camera1 kicks in first, then 2 and so on. Is this the way to ensure that all 5 stream start (and end) at the same time.

Thanks in advance

You would need a pulse generator like a common frequency generator. Also keep in mind, that 5 cameras will create 92 MByte per second. Using a codec, the size is reduced approx. 50% or less. Please make sure, that your harddisk can handle this amount of data.
