DAHUA DH-HAC-D1A21P 2MP Indoor Dome Camera

The DAHUA DH-HAC-D1A21P is a high-definition indoor dome camera designed to provide reliable security monitoring in homes, offices, retail shops, and other indoor environments. Offering sharp 2MP resolution, advanced night vision, and user-friendly features, this camera ensures dependable surveillance performance at an affordable price point.

High-Definition 2MP Video Quality

Equipped with a 1/2.7″ CMOS image sensor, the DH-HAC-D1A21P captures video at 1920 × 1080 pixels (Full HD) resolution. With its progressive scanning system, the camera delivers smooth, crisp, and clear images without motion blur or distortion. This makes it suitable for monitoring high-traffic indoor areas where detail is essential, such as entryways, hallways, lobbies, or retail counters.

Progressive Scanning for Smooth Video

Unlike interlaced scanning, which can create blurry lines during fast motion, progressive scanning captures every frame in full detail. This ensures more accurate and lifelike video, making it easier to identify people, objects, or suspicious activity in real time or during playback.

Wide Electronic Shutter Range

The DH-HAC-D1A21P supports a wide electronic shutter speed range:

• PAL: 1/25s ~ 1/100,000s
• NTSC: 1/30s ~ 1/100,000s

This allows the camera to adjust automatically to different lighting conditions, ensuring consistently balanced exposure whether in bright or dim indoor environments.

Superior Low-Light Performance

With a minimum illumination of 0.04 Lux at F1.85 (30 IRE), the camera performs impressively in low-light conditions. For complete darkness, the built-in infrared (IR) functionality activates automatically, enabling zero-lux performance when IR is on. This ensures continuous surveillance even when lights are switched off, offering peace of mind around the clock.

Enhanced IR Night Vision

The DH-HAC-D1A21P is equipped with powerful infrared LEDs that extend visibility up to 20 meters (66 feet). Its Auto/Manual IR On/Off control allows flexibility depending on your monitoring needs. In automatic mode, the camera intelligently switches between day and night modes to deliver the best possible image quality under changing light conditions.

Strong Signal-to-Noise Ratio

With an S/N ratio of more than 65dB, the camera minimizes noise and interference in the video feed. This results in clearer, more detailed images, even in challenging lighting environments, enhancing accuracy when identifying faces, objects, or movements.

Compact Dome Design for Indoor Use

The dome form factor makes the DH-HAC-D1A21P discreet, space-efficient, and tamper-resistant. Its sleek design blends seamlessly into modern interiors, making it ideal for indoor settings such as:

• Retail stores and shopping outlets
• Office spaces and meeting rooms
• Residential homes and apartments
