I've been doing some research for a co-worker who wants a camera system with US-based support. I recently stumbled across the Lorex's LNB3143 and noticed it contains a Sony EXMOR sensor (not to be confused with Starvis). The fact that Lorex highlights this feature in their listing---will it provide better nighttime performance compared to the LNB3163BW? I've tried to encourage the co-worker to go with Starlight, but is not familiar with optics; it seems everyone is different
