Hikvision DS-2CD23166G3-IS2UY/SL 2.8mm 16MP AcuSense DarkFighter Turret Camera

Hikvision DS-2CD23166G3-IS2UY/SL 2.8mm 16MP AcuSense DarkFighter Turret IP Camera with Strobe & Audio Alarm The Hikvision DS-2CD23166G3-IS2UY/SL 2.8mm is a premium 16 megapixel AcuSense fixed turret network camera designed for demanding residential, commercial and professional CCTV installations. Combining ultra-high-definition imaging with DarkFighter low-light technology, intelligent human and vehicle classification, active white strobe warning and built-in audible alarm, this camera provides advanced proactive security in a durable turret design. With a maximum resolution of 4608 × 3456, the DS-2CD23166G3-IS2UY/SL delivers exceptionally detailed surveillance footage. Its 1/1.8" Progressive Scan CMOS sensor, F1.6 aperture and Powered by DarkFighter technology provide excellent image performance in challenging lighting conditions. 2.8mm Wide-Angle Lens This version is fitted with a 2.8mm fixed lens, providing an approximately 94.5° horizontal field of view, 69.9° vertical field of view and 123.2° diagonal field of view. The wide-angle 2.8mm lens makes this model particularly suitable for locations where broad scene coverage is required, including driveways, entrances, front gardens, retail areas, offices, warehouses and car parks. 16MP Ultra High Definition CCTV The DS-2CD23166G3-IS2UY/SL records at resolutions up to 16 megapixels (4608 × 3456), delivering exceptional image detail across a wide surveillance area. The 4:3 high-resolution image format also provides additional vertical scene coverage compared with many conventional widescreen CCTV cameras, making it particularly useful where both horizontal and vertical detail are important. AcuSense Human & Vehicle Classification Hikvision AcuSense technology uses deep-learning algorithms to identify and classify human and vehicle targets. This helps reduce unnecessary alerts caused by irrelevant movement such as animals, vegetation or other environmental activity, allowing security operators to focus on events more likely to require attention. Active White Strobe Light & Audible Warning The /SL version features an integrated active white strobe light together with a built-in smart speaker for audible warnings. When linked to supported intelligent events, the camera can provide an immediate visual and audible deterrent when suspicious activity is detected, helping discourage intruders before an incident develops. Powered by DarkFighter Hikvision's Powered by DarkFighter technology provides excellent low-light imaging and helps retain useful scene detail when ambient lighting is limited. The camera can operate at illumination levels down to approximately 0.0008 Lux in colour at F1.6, while infrared illumination provides dependable monitoring in complete darkness. Up to 40m Smart Supplement Light Integrated supplementary lighting provides an illumination range of up to 40 metres, helping maintain useful surveillance coverage after dark. Smart supplement light control helps optimise illumination according to the scene and target distance, reducing the risk of overexposing nearby subjects. 130 dB True WDR The DS-2CD23166G3-IS2UY/SL incorporates 130 dB True Wide Dynamic Range, helping produce clearer images in difficult scenes containing strong contrasts between bright and dark areas. This is particularly useful for entrances, doorways, loading areas and other locations affected by strong backlighting or changing light conditions. Built-In Dual Microphones & Smart PA Speaker An integrated arrayed dual-microphone system captures audio alongside the camera's video stream, providing additional context for recorded security events. The built-in Smart PA speaker has a maximum output of 2W and can produce a sound pressure level of up to approximately 110 dB at 10cm, enabling powerful audible warnings and two-way audio functionality. Intelligent Perimeter Protection Advanced intelligent functions include line crossing detection, intrusion detection, region entrance detection and region exit detection. These analytics can distinguish human and vehicle targets, helping improve alarm accuracy and reduce unnecessary event notifications. Face Capture The DS-2CD23166G3-IS2UY/SL supports face capture, adding an additional layer of intelligent video analytics for compatible CCTV systems.

This is particularly important in ultra-high-resolution CCTV systems where efficient storage use can have a significant impact on recording retention times. Local microSD Recording up to 512GB A built-in memory card slot supports microSD, microSDHC and microSDXC cards up to 512GB, allowing local edge recording directly within the camera. Local storage can provide additional resilience alongside an NVR and can be useful in systems where edge recording or Automatic Network Replenishment is required. IP67, IK10 & NEMA 4X Protection The camera is designed for demanding indoor and outdoor CCTV installations with IP67 weather protection, helping protect the internal electronics from dust and water ingress. It also provides IK10 impact resistance and NEMA 4X anti-corrosion protection, making the DS-2CD23166G3-IS2UY/SL particularly suitable for exposed or higher-risk installation locations. PoE for Simple Installation Support for IEEE 802.3at Power over Ethernet allows both power and network data to be supplied through a single Ethernet cable when connected to a compatible PoE NVR or network switch. This simplifies installation and reduces the need for separate power cabling at the camera location.
