Full Product Description

360° Dual-Lens Surveillance Without Blind Spots

The Dahua DH-H3D 3+3MP IP Camera utilizes a coordinated dual-lens system to provide comprehensive room coverage without any blind spots. The 2.8mm fixed lens captures a wide-angle overview of the entire space, while the 6mm Pan & Tilt (PT) lens can rotate 349° horizontally and 90° vertically to focus on specific details. By utilizing the "Tap and View" feature in the DMSS app, users can simply tap anywhere on the wide-angle view, and the PT lens will instantly rotate to that exact spot for effortless, high-definition tracking.

AI Human & Pet Detection with Active Deterrence

This advanced security camera features built-in AI algorithms that accurately distinguish between humans, pets, and everyday distractions to minimize false alarms. When the Dahua DH-H3D detects an unauthorized human figure, its linkage tracking system automatically follows the target's movement path across the room. Simultaneously, it triggers a proactive sound and light alarm—flashing its built-in warning lights and playing a siren or custom voice prompt—to actively deter intruders before a break-in occurs.

Dual-Band Wi-Fi 6 & One-Click Proactive Call

The Dahua DH-H3D ensures a stronger, more reliable network connection by utilizing the latest Dual-Band Wi-Fi 6 (2.4GHz/5GHz) technology. This prevents video lag and connection drops, even in environments with heavy wireless interference. Additionally, the camera features a unique "One-click Proactive Call" button on its body; family members or staff can press this button to instantly initiate a two-way audio call to the administrator's smartphone via the DMSS app, making it an excellent emergency communication tool.

Pro Tip from Our Technicians

Always connect your Dahua DH-H3D camera to the 5GHz Wi-Fi band if the router is in the same room, as it provides significantly faster video loading times and smoother PTZ control. Our Sham Shui Po CCTV configuration specialists highly recommend inserting a high-endurance Micro SD card (up to 256GB) before mounting the camera, ensuring you have reliable local storage with zero monthly cloud subscription fees.
