How can the SD6AL830V-HNI have a further DORI Distance at 30x than the SD6AL245U-HNI at 45x? I get the SD6AL830V-HNI is 4K but almost double! Is this possible? Also, the SD6AL830V-HNI is listed as a Laser PTZ Network Camera but in the the specs it lists a 1/1.7” 12Megapixel STARVIS™ CMOS so wouldn't it be a Starlight Laser PTZ Network Camera?
