I needed a camera to stream events at a hall. Standard webcams are not useful at a distance, and I didn't want to fork over > $1K for a quality PTZ. ELP seems to be the only game in town, and they offer a pretty wide array of housings, image sensors, and lenses. I ended up testing 5 ELP cameras, finally selecting this one (5-50mm lens, Sony IMX322) as my keeper.The good:- The camera housing is tiny, solid build, standard camera mount, and lenses are interchangeable (if you can find them).- The IMX322 image sensor can handle 1080p@30fps, 16:9 format, excellent color reproduction and low light sensitivity.- The 5-50mm lens allows total flexibility in placement of the camera. You can zoom in on the podium from 50 ft if you want.- USB is _way_ cheaper than IP/ethernet, though somewhat limitingThe not so good:- Manual focus/zoom/iris limits the use cases, but was fine for my needs. Once dialed in to a stage wide framing, the main podium (center stage) is crystal clear, and the field of view is sufficient to capture the entire stage...decently enough.- While the lenses are good for the price range, there is noticeable chromatic aberration, and some vignetting at full 50mm zoom. Chromatic aberration can be mitigated somewhat with software filters.- If you want to ceiling mount you'll need "active" USB cables. I'm not this far in my install yet, but from my research to date I think we should be ok up to 50- 60' active USB cable. And I'm really hoping we don't need to fit a repeater through our existing cable run in the wall (I rather doubt it would fit...)
