• Motorised 2.8 6 mm varifocal lens (F1.6)for flexible field-of-view adjustment with remote control.
• DarkFighter low-light performancedelivering usable colour images down to 0.001 lux and smart IR up to 60 80 m depending on lens variant.
• IP67 and NEMA 4X corrosion resistancein a metal body for long-term outdoor exposure.
• Flexible power & storage: PoE (IEEE 802.3af) or 12 VDC; on-board microSD up to 512 GB plus NAS support and ANR.

Detailed specifications and benefits

• Sensor: 1/3" progressive-scan CMOS
• Resolution: 2688  1520 (4 MP)
• Frame rate: 25 fps (50 Hz) / 30 fps (60 Hz)
• Minimum illumination: Colour 0.001 lux (F1.6, AGC ON); BW with IR 0 lux

Benefit: The 4 MP sensor provides noticeably higher detail than 2 MP cameras, improving recognition of faces, license plates and small scene details. DarkFighters low-light performance means the camera can capture colour imagery in extremely dim conditions where other cameras would switch to monochrome or lose detail.

• Motorised varifocal 2.8 6 mm lens
• Aperture: F1.6
• Field of view (H): 2.8 mm  99.3; 4 mm  80.0

Benefit: The motorised varifocal lens enables installers to remotely adjust focal length and field of view without climbing ladders, saving time on commissioning and future adjustments. The wide F1.6 aperture helps gather more light for improved low-light performance.

• Smart supplement IR (850 nm)
• IR range: Up to 60 m (2.8 I) / up to 80 m (4 I)
• DarkFighter low-light technology

Benefit: Smart IR and DarkFighter provide extended night coverage and better contrast at long distances. This combination is especially useful for perimeter fences, parking areas and driveways where detail at night is essential.

• Compression: H.265 / H.264 / H.264+ / H.265+
• Streams: Main / sub / third
• WDR: 130 dB; Enhancements: BLC, HLC, 3D-DNR
• AcuSense: Deep-learning person & vehicle classification

Benefit: Efficient compression reduces bandwidth and storage costs while retaining image fidelity. Wide dynamic range and image enhancements help maintain usable footage in scenes with bright backlight or mixed lighting. AcuSense intelligently filters out common false positives, meaning fewer unnecessary alarms and faster review when events occur.

• On-board microSD up to 512 GB; NAS via NFS/SMB/CIFS; ANR supported
• Network: 1  RJ45 10/100/1000 Mbps; ONVIF Profile S/G/T
• Power: PoE (IEEE 802.3af, Class 3) or 12 VDC

Benefit: Local and network storage options add redundancy. PoE simplifies cabling by combining power and data over one Ethernet cable, lowering installation costs and enabling centralised power management.

• Rugged metal body and bracket
• Ingress rating: IP67; Corrosion resistance: NEMA 4X (moderate)
• Operating temperature: 30 C to 60 C

Benefit: Designed for outdoor exposure, the camera stands up to dust, rain and moderate corrosive environments. Its metal construction improves durability and heat dissipation compared with plastic housings.

Use cases and scenarios where the camera excels

The DS-2CD2T46G3-2IZY is versatile and well-suited to many outdoor surveillance needs. Typical scenarios where it performs strongly include:

• Residential perimeter protection:Monitor driveways, fences and entry points with improved detection and clearer night images for homeowner peace of mind.
• Commercial and retail frontages:Capture customer activity, deter theft and monitor after-hours access with clear 4 MP imagery.
• Parking lots and vehicle yards:Long IR range and AcuSense vehicle classification help capture license plates and reduce false-moving-object alerts.
• Construction sites and temporary installations:PoE and robust housing simplify setup and withstand harsh outdoor conditions.
• Small to medium enterprise perimeters:Use as part of a multi-camera network with centralised recording and managed alerts to focus security operator time on real events.

In each case, the combination of motorised varifocal adjustment, low-light imaging and intelligent classification delivers both operational flexibility and reduced ongoing review time.

Comparisons with similar products on the market

When considering alternatives, buyers typically weigh resolution, analytics, low-light performance, build quality and price. Heres how this model compares in common decision scenarios:

4 MP provides noticeably finer detail than 2 MP, improving recognition over longer distances and enabling more effective digital zoom. If your site needs identification-level detail rather than general motion detection, the 4 MP camera is a more future-proof choice.

Fixed-lens cameras are cheaper and simpler, but the motorised 2.8 6 mm varifocal lens on the DS-2CD2T46G3-2IZY allows remote framing adjustments during commissioning or after changes to the scene, reducing the need for physical access and rework.

Bullet cameras like this model offer longer IR throw and easier directional mounting for perimeter coverage. Domes are often chosen for vandal resistance and discreet aesthetics; choose the form factor that matches your mounting location and aesthetic requirements.

PTZs provide active tracking and wide-area coverage but at a higher cost and complexity. A fixed bullet with a wide field of view and analytics is a cost-effective choice for continuous monitoring of defined areas, while PTZs are better for active following or wide patrol routes.

AcuSense classification and DarkFighter low-light technology are competitive differentiators. When comparing to other manufacturers, consider the combined value of intelligent analytics, efficient compression and rugged build. Total cost of ownership includes installation time, bandwidth and storage—areas where features like PoE, H.265 and ANR matter.

Customer testimonials and feedback

No customer reviews were provided with the product brief. Below are representative, anonymised examples of the types of feedback installers and end users commonly report for cameras with this feature set:

• Installer comment:"The motorised lens saved us a lot of ladder time during setup. Adjustments from the NVR made commissioning quick and precise."
• Security manager:"AcuSense reduced our false alarm rate substantially; we now only get notified for people or vehicles instead of animals and lighting triggers."
• Property owner:"Night images are far clearer than our older cameras. We can see faces and vehicle details at distances where we used to have nothing but silhouettes."

These example responses reflect typical benefits customers seek: easier installation, fewer false alerts and improved night-time identification.
