Hello. I have a question to the owners of this camera (
DS-2DE4A404IW-DE). The specs claim: "The 2.8-12mm varifocal lens delivers a 69.5 to 26.48° horizontal field of view. The camera features endless panning, a -5 to 90° tilt range, and 4x optical zoom. " So the 4MP version only supports 70 degree angle, whereas the almost identical 2MP version called
DS-2DE4A204IW-DE (both have a 1/1.9" sensor) has a 90 degree horizontal viewing angle. I always thought that 2.8mm deliver around 90-100° viewing angle. This 69.5° seem a bit strange and narrow to me. Can someone confirm this?
I ordered one on Aliexpress for around 340 $ but now I am confused and contemplate cancelling my order. But the price (considering it features Darkfighter) was very tempting and I couldn't resist, so I tought I give it a try. But 70° are less than my current bullet camera with fixed lens (2.8mm).
