Dahua DH-HAC-HDW1209CLQP-A-LED 2MP Full Color HDCVI Dome Camera with Audio

Dahua HAC-HDW1209CLQP-A-LED — Full-Color Dome with Audio. The Complete Indoor/Outdoor Solution.

The Dahua HAC-HDW1209CLQP-A-LED combines the full-color 24/7 imaging capability of the HDW1209 series with a built-in microphone — making it the go-to choice for locations where both color image quality and audio surveillance are required. Lobby counters, retail floors, school corridors, office reception areas, and building entrances all benefit from the combination of dome discretion, color night vision, and audio capture.

🌈 Full-Color 24/7 Imaging — Color in Complete Darkness

Unlike standard IR cameras that switch to grainy black-and-white at night, this full-color camera uses warm white LED illuminators to flood the scene with visible light — capturing vivid, color-accurate footage even in total darkness. Color detail matters for security: identifying clothing colors, vehicle colors, and facial features is significantly easier from color footage than monochrome IR images.

🎙️ Audio-Equipped Dome — The -A Advantage

The -A suffix designates the built-in microphone model. Audio is transmitted over the coaxial cable via HDCVI’s 4-in-1 signal technology — no additional audio cable required. The dome form factor combined with audio makes this camera particularly suitable for retail environments (where customer-staff interaction monitoring is valuable), reception areas, and anywhere audio evidence adds contextual value to video footage.

📐 DWDR + BLC — Handling Difficult Lighting

Digital Wide Dynamic Range (DWDR) balances exposure between bright and dark areas in the same frame — essential for monitoring entrances, doorways, and any scene where bright outdoor light behind a subject would otherwise create a silhouette. Back Light Compensation (BLC) ensures subjects in front of bright windows or lights are properly exposed and identifiable.

📡 HDCVI Technology — Long-Distance Transmission Without Quality Loss

Dahua’s proprietary High Definition Composite Video Interface (HDCVI) transmits full-HD video, audio, data, and power over a single coaxial cable — up to 700 meters for HD video and 300 meters via UTP cable. Unlike IP cameras that require Cat5/6 cabling and network infrastructure, HDCVI cameras work directly with existing coaxial cable runs — making them the ideal upgrade path for existing analog systems or new installations where network infrastructure is unavailable.

🔌 Multi-Format Compatibility — CVI / CVBS / AHD / TVI

The camera supports four video output formats — HDCVI, CVBS (analog), AHD, and TVI — switchable via the OSD menu or a UTC controller. This makes it compatible with virtually every DVR and XVR system in the market: Dahua, Hikvision, and third-party recorders. No proprietary lock-in. No compatibility guesswork.

🛡️ IP67 Weather Protection — Built for Bangladesh’s Climate

IP67 rated — fully dustproof and waterproof up to 1 metre submersion for 30 minutes. Survives monsoon rains, humidity, construction dust, and extreme heat without degradation. Operating temperature range: -40°C to +60°C. Built to run continuously in outdoor installations year-round.

⚡ Advanced Signal Quality

Signal-to-noise ratio greater than 65dB — ensuring clean, clear video with minimal interference even over long cable runs. 2D/3D Digital Noise Reduction (DNR) reduces image grain in low-light without sacrificing detail or sharpness. BLC (Back Light Compensation) and WDR (Wide Dynamic Range) ensure balanced exposure in high-contrast scenes.
