wire or wireless Remote Switch?

[polygon]

Hi all,
     I use wireless trigger but the shutter speed must under 1\10's to avoid black frames. does any one doubt on the wireless trigger?  if it delays, the cameras would delay.
   Any one use the wire trigger instead of wireless ? do you have black frames too?

    I tested the wireless trigger , it seems  no delay when I triggered among the  cameras,  but some cameras delayed when I triggered from far away,  so I doubt it still has very small delay even very near the cameras.

hi polygon
i have developed both solutions to trigger 16 cams and the wire if more reliable so far.
my wireless system was based on radio triggers from adafruit, and depending on the remote control location i have delays and black frames
maybe with expensive triggering systems from the market, you can sync with more reliability
feedbacks would be appreciated
