Product SKU: DH-IPC-HDBW3541F-AS-S2
Product Overview
The Dahua DH-IPC-HDBW3541F-AS-S2 is a 5MP WizSense fixed-lens dome camera designed for entrances, retail areas, offices, building perimeters and other locations where accurate event detection and a tamper-resistant housing are important. Buyers can select a 2.8mm, 3.6mm or 6mm lens to match the required balance between broad coverage and more concentrated detail. The camera supports tripwire and intrusion detection with human and vehicle classification, along with SMD 4.0 for more relevant motion alerts. Built-in infrared illumination provides night vision up to 30 metres, while 120dB WDR assists in scenes containing bright and shaded areas. A built-in microphone, alarm and audio connections, microSD recording up to 256GB, PoE power and IP67/IK10 protection make it suitable for varied indoor and outdoor installations. This model is listed within Dahua’s discontinued range, so current availability and replacement planning should be confirmed before purchase.
Key Capabilities
Detailed 5MP Imaging
The camera outputs up to 2960 × 1668 resolution at 20 frames per second, providing more recorded detail than standard 4MP models. It can also operate at 4MP resolution at up to 25 or 30 frames per second when smoother motion is preferred.
Human and Vehicle Classification
Tripwire and intrusion rules can classify people and vehicles, helping the system focus on relevant perimeter events instead of treating every movement the same. SMD 4.0 provides additional human and vehicle filtering for motion-based event searches and notifications.
Three Fixed-Lens Choices
The 2.8mm option provides broad scene coverage, the 3.6mm lens offers a balanced general-purpose view, and the 6mm version concentrates detail on a narrower area. Selecting the correct lens before purchase is important because the focal length is fixed rather than motorised.
Low-Light and IR Monitoring
Low-light sensitivity and two built-in infrared LEDs support surveillance after dark, with a stated IR distance of up to 30 metres. The camera uses monochrome infrared imaging in very dark conditions rather than a white-light system that maintains continuous full-colour video.
Audio and Alarm Integration
A built-in microphone records sound directly at the camera, while separate RCA audio input and output connections support compatible external equipment. One alarm input and one alarm output allow the camera to participate in a broader event-driven security installation.
Flexible Recording and Installation
Recordings can be stored on a microSD card up to 256GB or sent to compatible network storage and recorders. IEEE 802.3af PoE simplifies cabling, while the metal IP67 and IK10 housing suits exposed or tamper-prone mounting positions.
Best For
- Shop Entrances and Retail Areas: Human and vehicle classification helps create more relevant alerts around customer entrances, loading zones and after-hours access points.
- Offices and Reception Areas: The compact dome shape, built-in microphone and selectable lens options suit internal public-facing spaces.
- Outdoor Building Perimeters: IP67 weather protection, IK10 impact resistance and 30-metre infrared illumination suit exposed walls, walkways and side access areas.
- Schools and Strata Properties: The vandal-resistant enclosure is useful in shared or publicly accessible locations where a standard plastic camera may be more vulnerable.
- Edge-Recording Installations: The microSD slot provides local recording for standalone use, recording redundancy or event backup when correctly configured.
Why Choose the DH-IPC-HDBW3541F-AS-S2
The DH-IPC-HDBW3541F-AS-S2 combines useful security analytics with a compact, impact-resistant dome design. Compared with a basic motion-detection camera, its WizSense functions can classify people and vehicles within intrusion and tripwire rules, reducing the time spent reviewing movement caused by less relevant activity. The selectable fixed-lens versions also allow the camera to be matched to either wide room coverage or a more focused target area. Built-in audio, alarm connections and local microSD storage provide more integration options than a basic camera with video output alone. Supplied by Security Wholesalers, this model is best considered for compatible existing systems, replacement requirements or installations where remaining stock is available, as it is part of Dahua’s discontinued product range.
Buyer Decision Tips
Lens Selection Tip: Choose the lens before ordering. The 2.8mm model provides the widest view, while the 6mm version shows a smaller area with greater pixel concentration. These are fixed lenses and cannot be remotely zoomed or adjusted after installation.
Product Lifecycle Tip: This camera is listed as discontinued. For a new multi-camera installation, compare remaining stock, firmware support and replacement availability with a current Dahua model before standardising the entire site on this series.

Choosing the Right Model
- Choose the 2.8mm version if: Broad coverage of an entrance, room, reception area or short-distance outdoor scene is the priority.
- Choose the 3.6mm version if: You need a balanced view that is narrower than 2.8mm without concentrating as tightly as the 6mm option.
- Choose the 6mm version if: A smaller target area or more distant access point requires greater pixel concentration and wide coverage is less important.
- Choose a motorised-lens camera if: The field of view must be adjusted remotely or fine-tuned after installation.
- Choose a current-generation model if: Long-term availability, standardisation and ongoing firmware support are priorities for a new installation.
FAQs
- Which lens option should I choose for the DH-IPC-HDBW3541F-AS-S2?
The 2.8mm version provides the widest view at approximately 111 degrees horizontally, making it suitable for entrances, reception areas and broad room coverage. The 3.6mm option narrows the view to around 92 degrees for more balanced general surveillance. Choose the 6mm version when a tighter 57-degree view and more detail on a smaller, more distant area are more useful than wide coverage.
- Can the DH-IPC-HDBW3541F-AS-S2 distinguish people and vehicles?
Yes. The camera supports tripwire and intrusion detection with human and vehicle classification, along with SMD 4.0 for more targeted motion events. This helps reduce alerts caused by less relevant movement compared with basic pixel-based motion detection. Performance still depends on correct camera positioning, detection-zone setup, target size and scene conditions, so the rules should be tested during commissioning.
- How does this 5MP WizSense camera perform at night?
The DH-IPC-HDBW3541F-AS-S2 includes infrared illumination rated to a maximum of 30 metres and has low-light sensitivity down to 0.005 lux in colour and 0.0005 lux in black and white under the stated test conditions. It is an infrared night-vision camera rather than a full-colour white-light model, so very dark scenes will normally switch to monochrome IR imaging.
- Does the DH-IPC-HDBW3541F-AS-S2 support audio recording?
Yes. A built-in microphone allows the camera to capture audio when recording and privacy settings are configured appropriately. It also provides one RCA audio input and one RCA audio output for compatible external equipment. The camera does not include a built-in speaker, so it should not be treated as a complete standalone two-way-audio camera without the required external audio hardware and system configuration.
- Is the DH-IPC-HDBW3541F-AS-S2 suitable for exposed outdoor locations?
Yes. The metal dome housing carries IP67 weather protection and an IK10 impact-resistance rating, making it suitable for many exposed and vandal-prone locations when installed correctly. The stated operating range is -40°C to +60°C at less than 95% relative humidity. Cable entries, junction points and mounting surfaces still need appropriate sealing to maintain reliable outdoor protection.
- Can this Dahua camera record without an NVR?
Yes. The camera supports a microSD card with a stated maximum capacity of 256GB, allowing local edge recording when a suitable card is installed and configured. It can also send recordings to FTP, SFTP or NAS storage. An NVR remains useful for centralised recording, longer retention, multi-camera playback and features such as refined smart search or Quick Pick when paired with compatible Dahua equipment.
- Does the DH-IPC-HDBW3541F-AS-S2 support PoE?
Yes. The camera supports IEEE 802.3af PoE through its 10/100Mbps RJ-45 network connection, allowing power and data to share one Ethernet cable from a compatible PoE switch or NVR. It can also be powered from a separate 12V DC supply. Maximum consumption is stated at 7.2W with PoE when WDR, infrared and intelligent functions are operating.
- Is the DH-IPC-HDBW3541F-AS-S2 a discontinued camera?
Yes. The DH-IPC-HDBW3541F-AS-S2 is listed in Dahua’s discontinued product range, so availability may be limited and future firmware or service arrangements should be checked before purchase. Buyers sourcing remaining stock through Security Wholesalers should confirm the selected lens, current availability and whether a newer replacement would be a better choice for a new installation or long-term standardisation.
