Hikvision 4 MP AcuSense Motorised Varifocal Bullet Camera 2.8-4 mm PoE IP67 DS-2CD2046G3-IZ2UY/SL

Introduction: What the Hikvision 4 MP AcuSense Motorised Varifocal Bullet Camera Offers

The Hikvision DS-2CD2046G3-IZ2UY/SL is a purpose-built outdoor IP network camera that combines a 4 MP sensor, Hikvision’s AcuSense deep-learning analytics and DarkFighter low-light imaging in a weatherproof bullet housing. Designed for perimeter, entry and parking-area surveillance, the camera pairs a motorised 2.8 6 mm varifocal lens with selectable smart supplement lighting, two-way audio and an active strobe/audio alarm. In short, it’s a feature-rich option for installers and end users who want improved detection accuracy and reliable night-time performance without complex add-ons.

Key Features at a Glance

• 4 MP resolution(2688 7520) at up to 30 fps for clear identification and evidence-grade footage.
• Motorised 2.8 6 mm varifocal lensfor on-camera field-of-view adjustment during commissioning.
• AcuSense analyticsusing deep-learning person and vehicle classification to reduce false alarms.
• DarkFighter technologyfor colour imaging in very low light and IR support up to ~40 m.
• Selectable supplement light(white or red/blue) and an active strobe + audio alarm for deterrence.
• Two-way audiowith dual built-in microphones and speaker for live interaction and recorded audio.
• PoE (IEEE 802.3at) or 12 VDC powerand IP67 metal housing for outdoor deployment.

Detailed Specifications and Benefits

The camera uses a 1/3" progressive-scan CMOS sensor to deliver 4 MP (2688 7520) images. With a maximum frame rate of 30 fps and 130 dB WDR, it handles scenes with both bright and dark areas effectively. The motorised varifocal 2.8 6 mm lens (F1.6) gives installers the flexibility to fine-tune the horizontal field of view from approximately 99.3° at 2.8 mm to 80.0° at 4 mm without physically swapping lenses—saving time on-site and allowing remote adjustment during setup.

DarkFighter technology improves colour reproduction at very low lux levels, enabling colour images in lighting conditions that would normally produce monochrome IR-only footage. Where IR is required, Smart IR extends reach to roughly 40 metres. The camera also offers a selectable smart supplement light (white or red/blue variants) that can be used as part of a deterrence strategy or to enhance forensic detail at night.

AcuSense deep-learning analytics classifies motion into people and vehicles, significantly reducing false positives triggered by foliage, small animals or weather. Built-in dual microphones and an integrated speaker support two-way audio and alarm playback; combined with the configurable active strobe and audio alarm this enables both remote monitoring and active deterrence from a single device.

Video compression options include H.265/H.264 and MJPEG with support for H.264+/H.265+ enhancements to save bandwidth and storage. The camera offers multiple streams (main, sub and third) so you can feed high-resolution recording while providing lower-bandwidth streams for mobile viewing. Local storage is supported via microSD (up to 512 GB) and network storage via NAS (NFS/SMB) with ANR to protect recordings during network interruptions. Broad platform compatibility is provided through ONVIF and Hikvision’s Hik-Connect and iVMS clients.

Power options include PoE (IEEE 802.3at, Class 4) or 12 VDC, making cabling flexible for different installation scenarios. Power consumption is around 16 W on PoE and slightly lower on 12 VDC. A robust metal housing rated at IP67 protects the camera from dust and heavy rain, and it operates across a wide temperature range (−30 °C to 60 °C), suitable for most outdoor conditions.

Use Cases: Where This Camera Excels

• Perimeter and site surveillance:AcuSense classification helps security teams focus on meaningful alerts (people and vehicles) rather than environmental noise, making it ideal for fencing, yards and industrial perimeters.
• Entry/exit points and gates:Motorised varifocal capability allows installers to frame license plates, faces or wide-area approaches with a single camera model.
• Car parks and loading bays:DarkFighter and Smart Supplement Light keep recording usable at night; two-way audio and strobe/alarm features assist in deterrence and remote management.
• Retail and small commercial sites:Clear 4 MP imaging combined with on-device analytics provides operational insights and reduces time wasted on false alarms.

Comparison with Similar Products

Within Hikvision’s portfolio, the DS-2CD2046G3-IZ2UY/SL positions itself as a mid-tier, feature-dense outdoor bullet camera—providing higher low-light capability and AcuSense analytics compared with basic 4 MP models that lack deep-learning classification. Compared with a fixed-lens 4 MP bullet, the motorised varifocal lens is a clear advantage for installers who want flexibility without extra on-site lens changes.

Against competitor offerings from other manufacturers (for example, mainstream Dahua or other value-brand IP cameras), this Hikvision model stands out for three reasons: (1) integrated AcuSense analytics for fewer false alarms, (2) DarkFighter low-light colour imaging, and (3) the combination of active lighting/strobe and two-way audio in a single IP67-rated unit. Higher-end cameras from premium brands may offer larger sensors, higher frame rates or built-in analytics with more configurable metadata, but those often come at a significantly higher price point.

Conclusion: Why Choose the DS-2CD2046G3-IZ2UY/SL?

The Hikvision 4 MP AcuSense motorised varifocal bullet camera is a compelling option when you need a balanced mix of daytime clarity, low-light colour performance and intelligent on-camera analytics. Its motorised lens simplifies deployment, PoE support reduces cabling complexity, and the integrated audio/strobe alarm features make it suitable for active deterrence strategies. With IP67 protection and a wide operating temperature range, it’s built for real-world outdoor use.

If your priorities include accurate event detection (people and vehicles), reliable night-time imaging and an installation process that minimises field work, this camera is well worth considering. Always check the official datasheet and user manual for precise installation, wiring and compliance details, and verify warranty and certification information with your authorised supplier before purchase.
