Hikvision 4 MP DarkFighter Long-Range Varifocal Bullet Network Camera DS-2CD3B46G2T-IZHSY (8-32 mm)

The DS-2CD3B46G2T-IZHSY is a Hikvision 4 MP motorized varifocal bullet network camera with a 8-32 mm lens, built around AcuSense deep-learning detection that classifies people and vehicles, so alarms come from real targets rather than leaves, rain or animals. DarkFighter low-light performance keeps detail in dim scenes.

• High quality imaging with 4 MP resolution
• Excellent low-light performance with DarkFighter technology
• Focus on human and vehicle targets classification based on deep learning
• Efficient H.265+ compression technology
• Clear imaging against strong back light due to 140 dB WDR technology
• Motorized varifocal lens for easy installation

Where it fits

Positions where the target distance is not settled before installation — perimeters, gates, car parks, long corridors. The motorized lens is zoomed and focused from the recorder or browser after mounting, so the field of view can be tightened or widened without a ladder.

Where it is the wrong choice: simple indoor rooms where a fixed-lens camera does the same job for less.

Before you order — three things to confirm

• The angle you need. Per the datasheet: 2.8 to 12 mm: horizontal FOV 114° to 41.8°, vertical FOV 59.3° to 23.6°, diagonal FOV 141.3° to 48.1° 8 to 32 mm: horizontal FOV 42.5° to 15.2°, vertical FOV 23. Send us the mounting height, the distance to the far edge of the scene and the width to cover, and we check the lens before ordering.
• Recorder and resolution. Confirm the NVR accepts 4 MP network cameras with H.265+, and that its bandwidth and disk space still meet your retention period with this channel added.
• Power and mounting. Power per the datasheet: 12 VDC ± 25%, 1.20 A, max. 14 W,two-core terminal block, 24 VAC ± 20%, 1.03 A, max. 14 W, PoE: IEEE 802.3at, Class 4, ma. Protection: IP67: IEC 60529-2013,IK10: IEC 62262:2002. Plan a PoE switch or NVR port and the bracket for the mounting surface.

Common questions

Will it work with my existing recorder?
It works with Hikvision NVRs that support 4 MP network cameras. For an older Hikvision recorder or a third-party system, send us the model and firmware and we confirm compatibility before ordering.

How far does it see at night?
The datasheet gives a supplement light range of 2.8 to 12 mm: up to 60 m; 8 to 32 mm: up to 80 m. Real distance depends on the scene and on reflective surfaces.

Do I need an AcuSense recorder?
Detection runs inside the camera. To search and filter recordings by person or vehicle on the NVR, an AcuSense-capable Hikvision recorder gives the full benefit.
