Low Cost Camera Interface (J9)
The 15-pin input connector is ideal for using low cost MIPI CSI-2, Raspberry Pi* compatible
cameras. The input channel is limited to 8M pixel images and 1080p30 or 720p60 video. For
higher performance imaging, use cameras that connect to Tetra’s USB 2.0 or Ethernet input
channels.
