Product SKU: IPC-B261H-MU
Product Overview
Built for directional outdoor coverage across driveways, perimeters and commercial approaches, the HiLook IPC-B261H-MU is a 6MP AcuSense fixed bullet camera designed to deliver accurate event detection with on-board audio capture. Featuring deep learning-based human and vehicle classification, it filters out motion from animals, foliage and other irrelevant sources, ensuring alerts are triggered by the targets that matter. Equipped with 40m infrared night vision, 120 dB True WDR and a 2.8mm fixed lens offering a horizontal field of view of approximately 98 degrees, it handles wide-angle coverage of entry points and open outdoor areas. It also includes a built-in microphone for audio recording alongside video, H.265+ compression to reduce bandwidth and storage demands, and IP67 weatherproof housing for year-round outdoor durability. PoE support simplifies installation by delivering both power and data over a single cable run.
Key Capabilities
AcuSense Human and Vehicle Classification
Deep learning algorithms distinguish between human and vehicle targets, filtering out irrelevant motion sources such as animals and debris. This reduces nuisance alerts and allows security staff to focus on genuine intrusion events at perimeters and entry points.
6MP Wide-Angle Coverage
The 3072 x 2048 resolution paired with a 2.8mm fixed lens delivers approximately 98 degrees of horizontal coverage, making this bullet well suited to monitoring wide outdoor approaches, loading areas and car park lanes from a single fixed mounting position.
40m Infrared Night Vision
Infrared LEDs extend visibility up to 40 metres in low-light or completely dark conditions. This makes the IPC-B261H-MU effective for monitoring outdoor access points, driveways and yard areas throughout the night without relying on external lighting.
120 dB True WDR
Wide Dynamic Range at 120 dB handles scenes with extreme contrast, such as a gate entrance with bright daylight behind a subject or a loading dock lit from one side. Detail is preserved in both bright and shadowed areas of the same frame.
Built-In Microphone with H.265+ Compression
The integrated microphone records environmental audio alongside video, adding sound context to recorded events. H.265+ compression reduces file sizes and lowers bandwidth consumption across the network, which matters in multi-camera installations with limited storage headroom.
Best For
- Perimeter and Fence Line Monitoring: The bullet housing and directional 40m IR range suit wall or pole mounting along outdoor perimeters where consistent coverage of a fixed approach is needed.
- Commercial Entry Points and Driveways: AcuSense human and vehicle detection triggers accurate alerts at gate entries and driveways, reducing nuisance notifications from wind-blown foliage or passing animals.
- Warehouses and Loading Docks: The IP67 housing and 6MP wide-angle lens handle dusty, wet or exposed industrial environments while capturing enough detail to identify people and vehicles across loading areas.
- PoE-Based IP Installations: Single-cable PoE deployment makes the IPC-B261H-MU straightforward to install in new builds or when upgrading from analogue systems using structured cabling.
Why Choose the IPC-B261H-MU
Where a standard bullet camera would record motion from any source, the IPC-B261H-MU uses AcuSense deep learning to confirm whether that motion is a human or a vehicle before generating an alert. Combined with 6MP resolution at 3072 x 2048, the camera captures enough image detail to review footage meaningfully across a wide outdoor scene, without the overhead of an 8MP system. The built-in microphone adds an audio layer to recordings that a camera without integrated audio simply cannot provide. The 120 dB True WDR handles the kind of backlit entrance conditions that cause lower-spec cameras to clip highlights entirely. At a mid-range price point in the HiLook by Hikvision line, the IPC-B261H-MU available through Security Wholesalers sits at a practical intersection of AI detection accuracy, image resolution, and weatherproof construction for commercial outdoor use.
Buyer Decision Tips
Lens and DORI Range: The 2.8mm fixed lens provides wide coverage at approximately 98 degrees horizontal, but the DORI distances confirm identification at 11m and recognition at 22m. If your primary goal is identifying faces or licence plates beyond 15-20m, consider a narrower fixed focal length or a varifocal model. For general perimeter detection and vehicle classification, the 2.8mm lens and 55m detect range perform well at typical mounting heights of 3-4 metres.

Ideal Use Cases
Industrial Yard and Perimeter Fencing
The IP67 housing and 40m IR range make the IPC-B261H-MU well suited to wall or pole mounting along industrial yard perimeters, where exposure to rain, dust and variable lighting is common.
Car Park Entrances and Exit Lanes
AcuSense vehicle classification and 6MP resolution allow the camera to log vehicle activity at car park entry and exit lanes, with enough image detail to review footage for incidents or disputes.
Warehouse Loading Docks
The wide 98-degree field of view from the 2.8mm lens covers the full width of a loading bay from a single mounting point, while AcuSense detection flags human presence in restricted dock areas after hours.
Commercial Driveways and Gate Entry Points
Mounted above a driveway gate or entry boom, the IPC-B261H-MU captures approaching vehicles and pedestrians with 120 dB WDR handling backlit conditions during morning and afternoon sun angles.
Construction Sites
PoE simplifies temporary or semi-permanent installation on construction sites, and the IP67 rating handles exposure to the dust, mud splash and weather typical of active sites throughout the build phase.
Choosing the Right Model
- Choose this model if: You need AcuSense human and vehicle detection in an IP67-rated outdoor bullet camera with a built-in microphone, 40m IR range and 6MP resolution for wide outdoor scene coverage via a 2.8mm fixed lens.
- Choose a different model if: Your installation requires identification of subjects at distances beyond 20m, where a narrower fixed focal length or motorised varifocal bullet would provide tighter framing and higher identification accuracy at range. If you also need active deterrence such as a strobe light or audible siren, a TiOC or active deterrence bullet variant would be more appropriate.
FAQs
- What does AcuSense detection actually do on the IPC-B261H-MU?
AcuSense uses a deep learning algorithm embedded in the camera to analyse motion and classify whether the moving object is a human or a vehicle. When a match is confirmed, an alert is generated. Motion from animals, wind-blown objects or insects near the lens does not trigger the same alert, which keeps notifications relevant to genuine security events.
- Can the IPC-B261H-MU record audio as well as video?
Yes. The camera includes a built-in microphone that captures environmental audio alongside the video stream. This audio is recorded when connected to a compatible NVR that supports audio recording. Note that only a microphone is built in, so this is a one-directional audio capture only.
- What is the effective IR range and how does it perform at night?
The infrared LEDs provide visibility up to 40 metres in low-light or zero-light conditions. At the confirmed minimum illumination of 0.01 Lux with AGC on, the camera transitions to IR mode via the IR cut filter, producing monochrome footage in darkness across the monitored area.
- What field of view does the 2.8mm lens provide?
The 2.8mm fixed lens delivers a horizontal field of view of approximately 98 degrees, which is suitable for wide outdoor scenes such as driveways, loading areas and yard entries. DORI distances are Detect at 55m, Recognise at 22m and Identify at 11m, so identification tasks are most accurate within the 11m zone.
- Does the IPC-B261H-MU support PoE and how does installation work?
The camera is powered via PoE, meaning a single Cat5e or Cat6 cable carries both data and power from a PoE switch or PoE NVR to the camera. This simplifies installation by eliminating the need for a separate power cable at each camera position, which is particularly useful on perimeter runs with multiple mounting points.
- Is the IPC-B261H-MU suitable for mounting in exposed outdoor locations?
The IP67 ingress protection rating confirms the camera is sealed against dust ingress and capable of withstanding water jets from any direction, making it suitable for outdoor mounting in exposed positions including under eaves, on external walls and on posts in open yards. The bullet housing also directs the lens forward, reducing the effect of rain streaking across the lens face compared to an upward-facing dome. The IPC-B261H-MU is part of the Security Wholesalers range of HiLook by Hikvision outdoor cameras.
