The Dahua HFW1431S-0280B-S4 IP camera is equipped with a 4MP 1 / 3 CMOS image sensor that provides high resolution in low light. It has a 2.8mm focal length lens and uses Smart IR (IR range up to 30m). With an advanced rate control algorithm that adapts to the scene, Dahua smart encoding technology provides higher encoding performance than H.265 and H.264, provides high quality video and reduces storage and transmission costs. The device uses motion detection. The camera has an IP67 rating, which makes it weatherproof and can operate normally in water at a depth of 1m for 30 minutes.
