Hikvision DS-2DY9188-AI2 2MP Ultra-Low Light PTZ Camera

Hikvision DS-2DY9188-AI2 2MP Ultra-Low Illumination Outdoor Positioning IP Camera

The Hikvision DS-2DY9188-AI2 is a professional-grade 2MP PTZ camera engineered for superior performance in ultra-low light environments. With color imaging capability at 0.002 Lux and monochrome sensitivity down to 0.0002 Lux, this camera delivers exceptional clarity in near-total darkness—a critical advantage for 24/7 surveillance in challenging lighting conditions. The 36x optical zoom (5.7–205.2mm focal length) combined with 16x digital zoom provides unprecedented flexibility for wide-area monitoring and detailed target acquisition across vast spaces.

Key Features

• Ultra-Low Illumination Imaging: 0.002 Lux color / 0.0002 Lux B/W with F1.5 aperture and AGC enabled
• 36x Optical Zoom: 5.7–205.2mm focal length with proportional zoom control
• 1000m IR Distance: Smart IR with intensity automatically adjusted based on zoom ratio for extended nighttime reach
• 2MP Full HD Resolution: 1920×1080 at up to 30fps (60Hz) main stream; multiple sub-streams for bandwidth optimization
• Advanced PTZ Control: 360° endless pan, -90° to 40° tilt; speeds up to 100°/s pan and 40°/s tilt; 300 presets with 8 patrol routines
• Intelligent Video Analytics: Face detection, intrusion detection, line crossing, audio exception, region entrance/exit detection
• True WDR and 3D DNR: Enhanced contrast and noise reduction for dynamic outdoor environments
• PoE Powered: 24 VAC, max 110W; edge recording via microSD up to 128GB
• IP66 Rated: Withstands harsh weather with 6000V lightning and surge protection

Technical Highlights

The camera features a 1/1.9" progressive scan CMOS sensor with variable aperture (F1.5–F3.4) and adaptive shutter control (1/1 to 1/30,000s). Multi-codec support includes H.264, MJPEG, and MPEG4 video compression alongside G.711, G.722.1, G.726, and PCM audio. Network connectivity includes full IPv4/IPv6 compliance, ONVIF/PSIA/CGI/Genetec API support, and simultaneous live view for up to 20 channels with 32-user access control. Dual audio channels, 7-input/2-output alarm integration, and RS-485 control enable seamless integration into complex security ecosystems.

Ideal Applications

Deploy the DS-2DY9188-AI2 for city surveillance, airport perimeter monitoring, critical infrastructure protection, traffic enforcement, and port/logistics facilities where round-the-clock visibility in low-light conditions is essential. Its robust construction and comprehensive feature set make it suitable for demanding outdoor environments requiring both wide coverage and pinpoint detail.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The DS-2DY9188-AI2 represents Hikvision's flagship approach to extreme low-light PTZ surveillance. The combination of ultra-sensitive imaging (0.0002 Lux B/W) with 1000m IR range and intelligent zoom-coupled IR adjustment delivers reliable performance across midnight conditions and heavy fog. The 36x zoom, true WDR, and 3D DNR work in concert to handle both backlit scenes and rapid illumination changes—critical for outdoor surveillance.

Multi-stream encoding, extensive analytics (face detection, intrusion, line crossing), and full ONVIF compliance ensure flexible deployment in enterprise and municipal networks. The IP66 rating and -40°C to 65°C operating range confirm durability in extreme climates. For large-scale monitoring requiring extended coverage with minimal blind spots, this PTZ excels; however, installations demanding true panoramic simultaneous multi-directional views may benefit from fixed multi-camera deployments.

The 300-preset limit supports most standard patrol patterns, though complex, continuously-varying routes may require cloud-based scheduling. Overall, this is a mature, battle-tested platform for mission-critical outdoor surveillance.
