Hi Leonardo, > Hi guys I would like to know how could I create an UDP server in Elphel > 353, in order to deliver images with 640x480 grayscale resolution. With fps > around 120.

You can setup the internal camera streamer to run in multicast mode, it then will use UDP.

It is possible, but will be very slow (far less than 120 fps) - that mode is only designed for test purposes, software debugging. If you need high quality images you may just use gamma=0.5 (matches sensor shot noise) and high JPEG quality settings. Even if the camera had high speed raw mode 640x480*120fps ~=37Mpix/sec. Even if you packed then so 3 pixels use 3 bytes (sensor output is 12 bit and the camera uses all the dynamic range when sending data in JPEG/JP4 mode), you will need some 55 MiB/sec bandwidth. The 100baseT that camera has is 5 times slower > Those images will be processed by some external computer…. > Yes, understood. For monochrome images the grayscale JPEG is fine, for color ones you may use JP4 to bypass color interpolation in the camera. Andrey
