Hikvision's Anti-Corrosion series; DS-2DT6223-AELY smart PTZ Dome Cameras; is able to effectively avoid acidic and neutral salt fog corrosion. DS-2DT6223-AELY is also able to capture high quality coloured images in dim light environments with its cutting-edge low illumination level down to 0.002Lux (colour). It is embedded with 1/1.9’’ progressive scan CMOS chip, making true WDR (120dB) and 2MP real-time resolution possible. With the 23X optical zoom Day/Night lens, the camera offers more details over expansive areas. PTZ dome camera smart functions The Anti-Corrosion PTZ camera also features a wide range of smart functions, including face detection, intrusion detection, line crossing detection and audio exception, benefitting users with great improvements in security efficiency and more importantly, with key events / objects being recorded for further forensic needs. These features are combined with smart tracking, which enables the camera to detect any progressively moving object and follow it within the camera’s area of coverage without fault. Smart Defog and EIS (Electronic Image Stabilisation) are further supported to improve image quality in challenging conditions.
