I want to connect an external flash to the 333 camera when using the command http://camera_ip/admin-bin/ccam.cgi?opt=vhxcsym to retrieve an image. Looking at the hardware the J2 connector has a EXT_EXPOS line, which could be connected to an opto coupler and could trigger an external flash. As the image retrieval is single frames and exposure is set to a low value, is this a feasible option? If not are there other options available?
Any suggestions would be appreciated.
