Hello Winston,

1) Video streamer format does not allow Exif data, you need to acquire images from the imgsrv - there is a min ihelp  at 192.168.0.9:2323 (without any other parameters). Saving images from it preserve all Exif data. It is also preserved when using camogm to record video sequence to the SSD/HDD

2) By default camera sensors are running in free running mode and so they are not synchronized. To synchronize them you need to use either external sync or just trigger them from the internal FPGA generator. Set TRIG=4 (triggered mode) and TRIG_CONDITION=0 (internal FPGA generator). See details on the wiki page:  https://wiki.elphel.com/wiki/Trigger_393

    Hi, Oleg
       We tried the USB GPS and it worked. The system could detect the device. And 192.168.0.9:2323/meta had GPS related tags. That info was just showed on the web. I could see it but I could not get it. Do you know how to get it?
       Another question is the two camera timestamp are not the same no matter whether or not we connect the gps.
