Surveillance camera DAHUA IPC-HDW3849H-AS-PV-0280B-S5 — 4MP, IP67, PoE, night vision

The DAHUA IPC-HDW3849H-AS-PV-0280B-S5 is a 4MP network surveillance camera for ceiling or wall mounting, designed for both indoor and outdoor monitoring. Its weatherproof IP67 housing and PoE power support simplify installation and protect the device in demanding environments. The camera integrates a sensitive CMOS image sensor, advanced noise reduction and built-in illumination to maintain image clarity at very low light levels, while an onboard microphone and Ethernet connectivity enable audio-enabled remote monitoring and straightforward integration into IP surveillance systems.

Advantages

This camera provides reliable day/night performance with an optical sensor and built-in light that support very low minimum illumination conditions. The IP67-rated housing ensures resistance to dust and water for outdoor use. Power over Ethernet (PoE) reduces cabling complexity by carrying power and data over a single cable. Onboard noise reduction and white balance options improve image quality across varied lighting situations. Integrated audio capture extends monitoring capabilities beyond video.

Suitable for

• Retail stores and commercial premises requiring continuous indoor/outdoor monitoring
• Residential properties needing perimeter or entry-point surveillance
• Parking areas, loading bays and building exteriors exposed to weather
• Small and medium business offices with centralized IP video systems

Key specifications

• Effective resolution: 4 megapixel network video (sensor supports up to 8 MP total)
• Image sensor type: CMOS, 1/2.7" optical sensor size
• Low-light performance: minimum illumination 0.0004 lx with built-in light and night vision
• Video features: noise reduction and adjustable white balance (Auto/Manual/Natural/Outdoor/Regional custom/Street lamp)
• Audio: built-in microphone for audio capture
• Network: Ethernet LAN connectivity with Power over Ethernet (PoE) support
• Mounting: ceiling or wall installation; color: white
• Environmental protection: IP67 weatherproof rating
• Weight: approximately 750 g

How to use

Mount the camera on a suitable ceiling or wall surface, ensuring a secure and level installation that provides the required field of view. Connect the device to your network switch or NVR using an Ethernet cable; when connected to a PoE-capable port or injector the camera will receive both power and data over the same cable. Configure network settings, exposure and white balance through the camera's web interface or management software, enable audio if required, and set recording or event rules for motion detection and storage.

Recommendations

For best low-light results, position the camera to minimize direct light sources in the frame and use the built-in illumination as intended. Use a PoE switch or injector that meets the device power requirements and ensure the installation point is protected from extreme physical impacts. Regularly check firmware updates and perform periodic cleaning of the housing to maintain optimal image quality and reliable operation.
