Hikvision DS-2CD2046G3-IZ2UY 4 MP AcuSense Motorised Varifocal Bullet Camera

Introduction: Hikvision DS-2CD2046G3-IZ2UY at a glance

The Hikvision DS-2CD2046G3-IZ2UY is a 4 MP outdoor bullet network camera engineered for perimeter and general outdoor surveillance. It combines Hikvisions AcuSense deep-learning person and vehicle classification, DarkFighter low-light imaging, and a motorised 2.8/4 mm point varifocal lens to deliver clear, actionable video in a wide range of conditions. With Power over Ethernet (PoE) support, H.265 compression and an IP67/NEMA 4X rated metal housing, this camera is built for straightforward installation and reliable outdoor operation.

Key features

• 4 MP resolution (2688 '),
• AcuSense person & vehicle classificationfor fewer false alarms and smarter event filtering.
• DarkFighter low-light technologyplus smart IR (up to ~40 m) for improved night performance.
• Motorised 2.8/4 mm point varifocal lens(F1.6) for flexible field-of-view adjustment without manual lens swapping.
• Robust outdoor housingwith IP67 ingress protection and NEMA 4X anti-corrosion design.
• Network-friendly: PoE (IEEE 802.3af), H.265/H.264 compression, ONVIF compatibility and multiple streams.

Detailed specifications and benefits

The DS-2CD2046G3-IZ2UY packs several performance-focused specifications that translate into practical benefits for installers and end users. Key technical points include a 1/3" progressive-scan CMOS sensor producing a 2688 x 1520 pixel image, and frame rates up to 25/30 fps depending on mains frequency. Efficient encoding (H.265/H.264, including H.265+) reduces storage and bandwidth requirements without sacrificing image quality.

• Lens: Motorised varifocal 2.8/4 mm (F1.6). The motorised function lets you remotely adjust focal length and fine-tune framing during setup, saving time on-site and enabling flexible coverage when the camera location or scene changes.
• Field of view: wide coverage at 2.8 mm (H 99.3') (wide) to 4 mm (H 80.0') (narrower) for scene flexibility.

DarkFighter technology improves sensitivity in low-light environments, providing clearer color and detail at dusk and in poorly lit scenes. Combined with smart IR up to roughly 40 metres, the camera maintains usable images at night—important for identifying subjects and recording meaningful evidence after dark.

AcuSense uses deep-learning models to classify targets as people or vehicles and supports perimeter protection functions such as line crossing, intrusion detection and region-based rules. The result is fewer nuisance alarms from animals, weather or foliage movement, and more targeted alerts for security operators.

• PoE (IEEE 802.3af) simplifies cabling by delivering data and power over a single Ethernet cable; typical power draw is low (around 7.5 W max).
• Storage options include microSD card support up to 512 GB and NAS (NFS/SMB) with ANR (Automatic Network Replenishment) for resilience during network outages.
• Standard network protocols and ONVIF Profile S/G ensure compatibility with many VMS and NVR platforms, making this camera suitable for integrator deployments.

Use cases and scenarios where the camera excels

The DS-2CD2046G3-IZ2UY is well-suited to a variety of outdoor surveillance needs thanks to its mix of analytics, low-light capability and robust housing. Typical use cases include:

• Perimeter security for commercial or industrial sites:AcuSense reduces false alarms while high-resolution imaging provides detail for event review and evidence collection.
• Residential perimeter and driveway monitoring:The wide field of view and nighttime performance are useful for spotting people or vehicles approaching property boundaries.
• Retail exteriors and car parks:Person/vehicle classification helps operators focus on suspicious activity, while PoE makes installation across parking lots simpler.
• Transport and access control points:Useful for monitoring entry lanes, gates and vehicle approaches where identification and event filtering are important.
• Integrator and installer projects:ONVIF compatibility, motorised lens adjustment and PoE speed deployment and reduce time on ladders or repeat site visits.

Comparisons with similar products

When comparing the DS-2CD2046G3-IZ2UY to other cameras in its class, consider three primary axes: analytics, low-light imaging and installation flexibility.

Many entry-level cameras rely on simple motion detection and sensitivity settings that generate high false-alarm rates. AcuSenses person/vehicle classification is a clear advantage for sites where alarm quality matters: it reduces operator workload and improves the signal-to-noise ratio for recorded events.

DarkFighter-equipped models offer better color and detail in low light than conventional cameras that switch to monochrome IR-only modes. For locations where identification at dawn/dusk or in low ambient light is important, DarkFighter provides more usable footage without needing additional lighting.

Motorised varifocal lenses allow remote adjustment of the view angle and focal length, saving installers time and reducing the need for precise mounting positions. Fixed-lens cameras can be cheaper, but they require a closer match between lens and mounting location or physical lens changes on-site.

Alternatives from other vendors may offer similar resolution and PoE capability, but differences usually appear in analytics sophistication, low-light performance and housing durability. When comparing models, weigh whether advanced analytics (person/vehicle classification), robust environmental resistance (NEMA 4X) and remote lens control are priorities for your deployment.

Customer testimonials and reviews

In general, feedback for Hikvisions AcuSense cameras from integrators and end users often highlights reliability of PoE installations, the convenience of motorised lens configuration, and noticeable reductions in nuisance alarms thanks to person/vehicle classification. As with any security purchase, prospective buyers should request sample footage, product demos or trial installations from suppliers when possible to confirm performance in their specific environment.

Conclusion: Why this camera is a strong choice

The Hikvision DS-2CD2046G3-IZ2UY delivers a balanced feature set for outdoor perimeter surveillance: a 4 MP sensor for clear detail, DarkFighter for low-light clarity, AcuSense analytics to reduce false alarms, and a motorised varifocal lens to simplify commissioning. Combined with PoE, efficient H.265 encoding and rugged IP67/NEMA 4X construction, its a practical choice for commercial, residential and integrator-led deployments where reliability and actionable alerts matter. Priced competitively against similar models, it represents a capable option for anyone seeking to upgrade outdoor camera coverage with smarter analytics and better night-time imaging.
