Hikvision DS-2CD3148G2-LISU 4MP AcuSense AI IR Dome Camera

Hikvision DS-2CD3148G2-LISU 4MP AcuSense AI IR Dome Camera

The Hikvision DS-2CD3148G2-LISU is a professional-grade 4MP outdoor dome camera engineered for intelligent surveillance in challenging environments. Built on AcuSense AI technology, this camera delivers advanced target classification, distinguishing humans and vehicles from other moving objects to minimize false alarms. With its IP67-rated weatherproof construction, infrared illumination up to 40 meters, and flexible lens options, it provides reliable round-the-clock monitoring for perimeter security, parking areas, and large outdoor spaces.

Key Features

• 4MP 1/3" progressive scan CMOS sensor with 2688 × 1520 native resolution
• AcuSense deep learning engine with human/vehicle classification and 1.5 TOPS computing power
• Dual supplemental lighting: IR (850 nm, up to 40 m) and white light with smart control
• Switchable fixed focal lenses (2.8mm or 4mm) with F1.0 aperture and wide field of view
• 120 dB wide dynamic range and advanced image enhancement (BLC, HLC, 3D DNR)
• IP67 weatherproof and IK10 vandal-resistant construction
• PoE power with optional 12VDC input; supports up to 30 fps at full resolution
• Face capture and people counting functionality
• Multiple codec support: H.265+, H.264+, H.264, H.265 with 4-stream architecture

Technical Highlights

The DS-2CD3148G2-LISU excels in extreme low-light conditions, achieving 0.001 Lux color sensitivity with AGC enabled and 0 Lux with supplemental lighting. The 2.8mm lens delivers a 100.2° horizontal field of view with 63-meter detection range, while the 4mm option provides 81.1° coverage and 78-meter detection capability. The camera supports simultaneous multi-stream output with flexible bitrate control (32 Kbps–8 Mbps), enabling bandwidth optimization across different network conditions.

Smart event detection includes line crossing, intrusion detection, region entrance/exit, scene change, audio exception, and defocus alerts—all with human/vehicle filtering. The integrated 1.5 TOPS AI accelerator supports multiple deep learning frameworks (Caffe, PyTorch, TensorFlow, PaddlePaddle, ONNX) and HEOP 2.0 OpendevSDK for custom application development. On-board eMMC storage (2 GB) and microSD card support (up to 512 GB) provide local recording redundancy, while network storage options include NAS with ANR (Auto Network Replenishment).

The camera provides comprehensive security features including IP address filtering, HTTPS encryption, 802.1X authentication, and watermarking. It supports 32 concurrent user accounts across three privilege levels and integrates with Hikvision's ecosystem via iVMS-4200, Hik-Connect, and Hik-Central platforms.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The DS-2CD3148G2-LISU represents Hikvision's mature approach to edge AI in fixed outdoor surveillance. The combination of switchable optics and dual-lighting capability (IR + white light) makes it versatile for diverse outdoor scenarios—from low-illumination perimeters to complex scenes requiring color detail. The AcuSense filtering and 1.5 TOPS compute capacity enable real-time analytics without server dependency, critical for security operations managing alert fatigue.

The 120 dB WDR and F1.0 aperture handle backlit and high-contrast scenes effectively. For integrators, the support for HEOP 2.0 SDK and standard deep learning frameworks simplifies custom model deployment. The PoE option with optional DC input provides installation flexibility in areas with inconsistent power infrastructure. The four-stream encoding model, including dedicated 10 fps third/fourth streams, optimizes bandwidth for mixed bitrate clients (mobile, web, NVR). Native H.265+ coding reduces storage by 50% versus H.264, a significant consideration for long-term retention. The camera's SNR rating (≥52 dB) and environmental noise filtering support integrated audio triggering for security events.
