Table 1 Camera behavior can vary radically across vendors and models. Under congested network conditions for example, cameras may permanently drop frames or attempt to resend missed frames at the expense of live data. The Panasonic camera in this case output "smoother" video (fewer frame drops between two successive frames) under heavy network congestion (until its on board cache is exhausted) at the cost of delays in upwards of 6 seconds.
