IP security camera Hikvision Pro Series DS-2CD2346G2H-IU (4mm) Turret Outdoor 2688×1520, 30 fps, 81.1° H

The Hikvision Pro Series with AcuSense DS-2CD2346G2H-IU (4mm) is an outdoor turret IP security camera designed for ceiling or wall mounting. It captures 4 MP (2688 x 1520) resolution video with a 4 mm lens and a horizontal field of view of about 81.1° and vertical 44.7°. The camera uses a CMOS sensor and Hikvision’s AcuSense deep-learning algorithm to classify human and vehicle targets, reducing false alarms. It supports wired Ethernet connectivity and is built for outdoor use with IP67 dust and water resistance and a white turret form factor weighing approximately 0.55 kg.

Advantages

The camera provides high-quality imaging at 4 MP resolution and improved low-light sensitivity with DarkFighter technology. Wide Dynamic Range (120 dB WDR) helps maintain clear images in scenes with strong backlight, while H.265+ compression reduces bandwidth and storage usage. AcuSense target classification focuses alarms on people and vehicles to increase detection efficiency. Additional features include up to 30 m IR night vision, built-in microphone on the -IU model for audio monitoring, and robust outdoor protection (IP67).

Suitable for

• Perimeter and exterior building surveillance
• Parking lots and driveways monitoring
• Business entrances and outdoor walkways
• Sites where human/vehicle alarm classification is required to reduce false alarms

When it may not be suitable

This turret camera is intended for outdoor fixed installations on ceilings or walls; it is not designed as a pan-tilt-zoom (PTZ) unit and therefore cannot actively track moving targets. Environments without wired Ethernet infrastructure will require additional cabling or PoE switches because the camera does not provide Wi‑Fi connectivity.

Key specifications

• Image sensor: CMOS, optical size 1/3" (25.4 / 3 mm)
• Resolution: 4 MP (2688 x 1520)
• Lens: 4 mm, horizontal view ~81.1°, vertical ~44.7°
• Frame rate: up to 30 fps
• Night vision: IR up to 30 m
• Video compression: H.265+
• Low-light tech: DarkFighter
• Wide Dynamic Range: 120 dB WDR
• Target classification: Human and vehicle (AcuSense)
• Ingress protection: IP67 (dust and water resistant)
• Mounting: ceiling or wall turret
• Connectivity: wired Ethernet (PoE compatible)
• Weight: approx. 0.55 kg

How to use

Mount the turret camera on a suitable ceiling or wall surface using the supplied hardware. Connect the camera to a PoE-capable Ethernet switch or injector for power and network connectivity, then configure network settings and recording parameters using Hikvision’s software or a compatible VMS. Enable AcuSense classification and adjust sensitivity and detection zones to match the monitored area. Test night performance and IR range after installation to ensure adequate coverage.

What to consider before purchase

• Availability of wired Ethernet and PoE at the installation site
• Required field of view and whether 4 mm lens meets coverage needs
• Need for human/vehicle classification to reduce false alarms
• Whether ceiling/wall fixed mounting suits the surveillance plan (no PTZ)
• Environmental exposure (IP67 rated for outdoor use)

Recommendations

For reliable detection, mount the camera at a height and angle that keeps people or vehicles within the recommended observe/recognize distances (observe ~31 m, recognize ~15 m). Use PoE for simplified installation, configure AcuSense zones to avoid non-relevant motion sources, and schedule regular firmware updates and maintenance checks to ensure continuous performance.
