PROS: While I have not used the RTSP features the SDI - SDI performance has been amazing low latency. Truly a frame or two. The build quality is excellent. By and large the device just works. CONS: The user interface is limited and awkward if you want to go play with settings. Boot up times are long (I am guessing there is a full linux based OS hiding in there somewhere.) If left on for a long time (weeks) strange behavior creeps in that a reset fixes.
