Just checking on my existing cameras, I see I have several DS-2CD2386G2-I which have identical specs as the PCI-T18f2s in term of image hardware: 1/1.8" 4k sensor, f/1.6 2,8mm lens. So I guess I know already what to expect. To bad about DS-2CD2387G2-LSU/SL with it's 1/1.2" sensor and f/1.0 lens. That is a LOT more light. HOWEVER - looking more closely at the specs for the DS-2CD2387G2-LSU/SL, I'm suspicious of the claimed sensor size. The field of view is stated as 102 degrees which better matches with a 1/1.8" sensor - NOT a 1/1.2" sensor. Either the sensor size is misstated, the field of view is misstated or the lens focal length is misstated.
