The NewTek TriCaster 40 is an all-in-one live production switcher, streaming system, and recorder that costs much less than its higher-model TriCaster relatives.
Like most of its relatives, TriCaster 40 streams to the Web, records program out as MPEG2, and features 4 camera inputs and 14 channels to switch between. So how is it available at a lower price-point? The outstanding reasons are that its connections are analog only and that it doesn't come with a control surface nor a character generator software. Switcher software is included though and comes installed.
So if component and composite inputs/outputs are enough for your productions, and so are a mouse and keyboard in place of a control surface, then the TriCaster 40 will do everything you need it to. Moreover, it's easy to set up, to use, and to carry, and you can at any future time separately purchase and add a control surface and CG software to it.
