Whether you need to secure homes, offices, shops, or public areas, this compact dome camera offers professional-grade performance at an affordable price.

Crystal-Clear 2MP Full HD Resolution

At the heart of this camera is a 2MP CMOS image sensor that delivers maximum resolution of 1920 (H) × 1080 (V). With progressive scanning, the DH-HAC-T1A21P-U-IL ensures smooth, sharp images without motion blur, making it ideal for monitoring moving subjects.

Exceptional Low-Light Performance

The camera excels in low-light scenarios with a minimum illumination of 0.02 lux @F2.0 (Color), 0.002 lux @F2.0 (B/W), and 0 lux with IR on. Its dual light technology combines IR illumination (25m range) and warm light (20m range) to ensure vivid color imaging or clear black-and-white video at night. The camera automatically switches illumination modes based on conditions, ensuring visibility in complete darkness while preventing overexposure or underexposure.

Intelligent Illumination Control

Featuring Smart IR & Warm Light (WL) modes, the camera intelligently adjusts brightness to deliver balanced images in varying lighting conditions. With two warm light and two IR LEDs, the DH-HAC-T1A21P-U-IL adapts to diverse surveillance environments, reducing hotspots and ensuring even lighting across the field of view.

Flexible Lens Options for Wider Coverage

The camera is equipped with fixed focal lenses of 2.8mm or 3.6mm, providing options to suit different surveillance needs.

• 2.8mm lens delivers a wide 100° horizontal field of view, suitable for monitoring open areas like retail shops, entrances, and small offices.
• 3.6mm lens offers a narrower 80° field of view, ideal for focusing on specific zones such as corridors, parking areas, or access points.

Both lens options provide excellent coverage, while the DORI (Detect, Observe, Recognize, Identify) distances ensure accurate monitoring ranges.

Advanced Video Features

The DH-HAC-T1A21P-U-IL supports multiple video formats including CVI, TVI, AHD, and CVBS, all selectable via a single BNC port, making it highly versatile and compatible with different DVR systems.

Key video features include:

• 1080p Full HD at 25/30 fps (CVI/AHD/TVI) for smooth live video.
• 960H analog support for legacy systems.
• Day/Night ICR for automatic color-to-B/W switching.
• 2D Digital Noise Reduction (2D NR) for clearer images in low-light.
• DWDR (Digital Wide Dynamic Range) to balance bright and dark areas in high-contrast scenes.
• BLC/HLC for improved clarity in backlit or overexposed environments.

With mirror and privacy masking (up to 8 zones) functions, the camera can be tailored to meet specific monitoring needs while protecting privacy.

Built-In Audio for Enhanced Security

Equipped with a built-in microphone, the camera provides synchronized audio recording along with video footage. This feature adds valuable context to recordings, making it easier to interpret incidents and improve situational awareness.

Robust Build and Installation Flexibility
