Securty-cam app zoo example times out in headless mode

254 Views

I'm using the Movidius neural compute stick 1 with Raspberry Pi and running the security-cam.py demo script in headless mode. I've disabled the display:

    # If a display is available, show the image on which inference was performed
    # if 'DISPLAY' in os.environ:
    #    img.show()

.... Works perfectly when connected by SSH to master PC but seems to time out after 15 minutes when the network is disabled. I can see this by looking at the times on the images captured.

Does anybody know why this is happening or how to cure it?
