Description

Hikvision DS-2CD3346SWDA4-L 4MP Dual-Light Full-Color Turret Camera — Clear imaging day and night with intelligent audio and two-way talk.

The DS-2CD3346SWDA4-L is a 400万像素（4MP）turret camera designed for round-the-clock surveillance. Its dual-light system automatically switches between white light and infrared illumination, delivering full-color images in low-light conditions and clear black-and-white footage in complete darkness. The built-in microphone and speaker enable full-duplex two-way audio, allowing you to communicate remotely via the mobile app. Intelligent detection functions (line crossing, intrusion) trigger accurate alerts.

Key Features:
✅ 4MP 2560×1440 Resolution: 1/1.8″ Progressive Scan CMOS for high-definition clarity.
✅ Dual-Light Illumination: White light up to 30m + IR up to 30m, auto-switching.
✅ Built-in Mic & Speaker: Supports full-duplex two-way audio and mobile app communication.
✅ Intelligent Detection: Line crossing and intrusion detection.
✅ H.265/H.264/MJPEG Compression: Efficient encoding saves bandwidth and storage.
✅ 120dB WDR & 3D DNR: Clear images in challenging lighting conditions.
✅ IP67 Weatherproof: Dust-tight and water-resistant for outdoor use.
✅ PoE or DC12V Power: Flexible installation options.
