Product SKU: DH-IPC-HDW4631EMP-ASE
Product Overview
The Dahua DH-IPC-HDW4631EMP-ASE is a 6MP IP eyeball network camera designed for installers and integrators who need high-resolution surveillance with reliable low-light performance. Built around a 1/2.9″ 6-megapixel STARVIS CMOS sensor, it delivers sharp 3072×2048 footage with up to 50m IR night vision, making it well suited to both indoor and outdoor environments. The 2.8mm fixed lens provides a wide field of view ideal for monitoring entry points, corridors, and open areas. H.265 encoding reduces bandwidth and storage demands without compromising image quality, while the built-in microphone adds audio capture without the need for external devices. With IP67 weatherproofing, IK10 vandal resistance, WDR at 120dB, and ePOE support, this camera is a capable and cost-effective choice for commercial and residential IP security installations.
Key Capabilities
6MP High-Resolution Imaging
The 6-megapixel STARVIS CMOS sensor captures detailed 3072×2048 footage, providing the clarity needed to identify faces, licence plates, and incidents across wide areas — critical for evidence-grade surveillance in commercial and residential applications.
50m Smart IR Night Vision
Integrated smart IR LEDs illuminate scenes up to 50 metres in complete darkness. The adaptive IR technology adjusts intensity to avoid overexposure on close subjects, ensuring consistently usable footage around the clock without additional lighting infrastructure.
120dB Wide Dynamic Range
With 120dB WDR, this camera handles high-contrast scenes such as bright doorways or sun-glare environments with ease. Both shadow and highlight detail are preserved simultaneously, reducing blind spots that would defeat a standard camera.
H.265 Efficient Encoding
H.265 triple-stream encoding cuts file sizes and bandwidth consumption compared to H.264, allowing longer recording retention on the same storage hardware. This makes it particularly valuable on multi-camera systems where NVR storage costs add up quickly.
Built-in Microphone
The integrated microphone enables audio recording and remote listening without running separate audio cabling. This simplifies installation and supports compliance or incident-review requirements where audio context is valuable alongside video footage.
IP67 Weatherproofing & IK10 Vandal Resistance
Rated IP67 for full dust ingress protection and water immersion resistance, and IK10 for impact protection, this camera withstands harsh outdoor conditions and deliberate physical attack — making it reliable in exposed or high-risk mounting locations.
Best For
- Commercial Entry Points: The wide 2.8mm lens and 6MP resolution make it ideal for monitoring building entrances, reception areas, and access gates where facial detail matters.
- Outdoor Perimeter Surveillance: IP67 and IK10 ratings ensure this camera operates reliably on external walls, soffits, and exposed mounting positions through rain, dust, and physical interference.
- Retail & Small Business: Smart detection and high-resolution imaging support loss prevention and incident review in retail environments without requiring expensive analytics hardware.
- Residential Security: Compact eyeball form factor and ePOE compatibility allow straightforward single-cable installation in homes requiring reliable day and night coverage.
- Multi-Camera IP Systems: H.265 encoding and PoE support make this camera efficient to deploy across larger NVR-based installations where bandwidth and storage costs need to be managed.
Why Choose the DH-IPC-HDW4631EMP-ASE
Cheaper 2MP or 4MP IP cameras may appear sufficient on paper, but when footage is reviewed after an incident, the lack of detail becomes apparent — faces are unrecognisable and licence plates are unreadable. The DH-IPC-HDW4631EMP-ASE addresses this with a full 6MP sensor that retains forensic-grade detail even when digitally zoomed. The combination of 120dB WDR and smart IR means performance holds up in challenging lighting conditions that defeat budget alternatives. The built-in microphone removes a common installation complexity, and H.265 encoding ensures that running 6MP cameras across a multi-channel system remains practical from a storage perspective. IK10 vandal resistance adds a layer of durability that standard cameras simply do not offer. Security Wholesalers stocks this model as part of a broader Dahua IP camera range, backed by warranty and local support — making it a reliable long-term choice for professional installations.
Buyer Decision Tips
Buyer Tip: This camera supports both standard PoE and ePOE. If you are running cable runs longer than the standard 100m PoE limit, confirm that your NVR or switch supports ePOE to take advantage of the extended transmission distance without additional extenders.
Buyer Tip: The 2.8mm fixed lens provides a wide field of view well suited to open areas and entry points. If your installation requires a narrower field of view for longer-distance identification — such as a driveway or corridor — review whether the 3.6mm optional lens variant is available before purchasing.

Choosing the Right Model
- Choose this model if: You need 6MP resolution with a built-in microphone, smart IR to 50m, WDR, and IK10 vandal resistance in a compact IP eyeball form factor with ePOE compatibility.
- Choose a different model if: You require active deterrence features such as a siren or white light, or need higher frame rates at full 6MP resolution — in which case reviewing the current Dahua WizSense or AI series range would be appropriate.
FAQs
- Does the DH-IPC-HDW4631EMP-ASE work with standard PoE switches?
Yes, this camera supports standard IEEE 802.3af/at PoE as well as ePOE for extended cable runs. It will power up and operate normally when connected to a standard PoE switch or PoE NVR port, making it straightforward to integrate into most existing IP network infrastructure. - What is the difference between PoE and ePOE on this camera?
Standard PoE supports cable runs up to approximately 100 metres. ePOE extends this to significantly longer distances, which is useful on larger properties or installations where running additional cabling or network extenders would otherwise be necessary. Confirm your NVR or switch supports ePOE before relying on extended runs. - Can this camera record audio as well as video?
Yes. The built-in microphone captures audio alongside video footage. Audio recording must be enabled in the camera or NVR settings, and local privacy laws regarding audio recording in surveillance contexts should be observed before enabling this feature. - Is the DH-IPC-HDW4631EMP-ASE compatible with Dahua NVRs?
Yes, this camera is designed to work within the Dahua IP ecosystem and is compatible with Dahua NVRs supporting H.265 decoding. It also supports remote monitoring via the DMSS mobile app and Dahua CMS platforms including DSS and PSS. - Does the camera support local storage without an NVR?
Yes. The camera includes a Micro SD card slot that allows local on-board recording independent of an NVR. This provides a useful backup recording option or enables standalone deployment in locations where running network cabling to a central recorder is not practical. - How does the 120dB WDR benefit real-world surveillance?
Wide Dynamic Range at 120dB allows the camera to simultaneously expose for both bright and dark areas within the same frame. This is particularly useful at entry points where sunlight behind a subject would normally silhouette them, making facial identification impossible with a standard camera. - Where can I purchase this camera and access support?
The DH-IPC-HDW4631EMP-ASE is available through Security Wholesalers, which stocks a full range of Dahua IP cameras along with compatible accessories, mounts, and NVR solutions. Support and warranty assistance are available through the same channel, providing a consistent point of contact for your installation. - What smart detection features does IVS provide on this camera?
The Intelligent Video System (IVS) on this camera supports smart detection functions such as tripwire and intrusion detection. These features allow the camera or NVR to generate alerts when objects cross defined lines or enter specified zones, reducing false alarms compared to basic motion detection.
