Product SKU: IPC-HFW5842E-ZE
Product Overview
Built for long-range directional coverage across perimeters, yards, and industrial approaches, the Dahua IPC-HFW5842E-ZE is an 8MP (4K) WizMind S-Series bullet camera that combines a motorized varifocal lens with deep learning analytics and a hardened outdoor body. Featuring a 2.7-12mm motorized lens and a 1/1.8-inch CMOS sensor, it captures full 3840 x 2160 resolution at up to 30 fps, giving installers genuine flexibility to frame coverage from a wide 113-degree angle down to a tighter 47-degree zoom without repositioning the camera. Equipped with 4 IR LEDs reaching 60 metres, it maintains usable nighttime imaging even across extended outdoor sightlines. It also integrates a WizMind analytics suite covering face detection, people and vehicle classification, SMD 3.0, heat mapping, people counting, loitering detection, sound detection, and IVS rules. Rated IP67 and IK10, with an operating range of -30°C to +60°C, it is well suited to demanding commercial and industrial installations where both intelligence and physical durability are non-negotiable.
Key Capabilities
8MP 4K Resolution at 30fps
The 1/1.8-inch CMOS sensor delivers 3840 x 2160 video at up to 30 fps. For perimeter and entry-point monitoring, this resolution allows meaningful post-event review of faces, vehicle types, and activity that lower-megapixel cameras would render ambiguous.
Motorized Varifocal Lens (2.7-12mm)
The F1.8 motorized varifocal lens spans 113 degrees at the wide end down to 47 degrees when zoomed, with a minimum close focus distance of 1.5 metres. Installers can set the precise coverage angle remotely, avoiding the need to physically reposition the camera after mounting.
60-Metre IR Night Vision
Four IR LEDs extend illumination to 60 metres, covering extended outdoor approaches such as loading dock entries, fence lines, and driveway corridors in complete darkness. With a minimum illumination of 0.0004 lux (B/W), useful imaging is retained even in near-zero ambient light conditions.
WizMind Deep Learning Analytics
The onboard WizMind suite includes face detection with attribute capture, people and vehicle classification, SMD 3.0, loitering detection, heat mapping, people counting by area and queue, sound detection, and IVS tripwire and intrusion rules. This significantly extends what the camera can report beyond simple motion events.
IP67, IK10 and Wide Temperature Range
Rated IP67 for dust and water ingress protection and IK10 for impact resistance, with an operating range from -30°C to +60°C. This combination suits exposed installations including coastal industrial sites, rooftop mounting, and environments where tampering is a practical risk.
120dB WDR, EIS, and Smart Codecs
120dB wide dynamic range handles high-contrast scenes such as gate entrances with direct sunlight and shadowed interiors simultaneously. Electronic image stabilisation reduces blur from wind or vibration. Smart H.264+/H.265+ and AI codecs help control storage and bandwidth without sacrificing image quality in monitored zones.
Best For
- Perimeter and Fence-Line Monitoring: The 60-metre IR range and varifocal lens make the IPC-HFW5842E-ZE well suited to long sightlines along fence lines, boundary walls, and property edges where consistent nighttime coverage is required.
- Commercial Loading Docks and Yard Entries: The bullet housing mounts directionally on walls or poles to cover specific approach paths, while vehicle classification and IVS tripwire rules allow event-based alerting rather than constant review.
- Industrial and Utility Site Surveillance: The IK10 vandal rating and -30°C to +60°C operating tolerance mean the camera can be deployed in exposed or harsh conditions including factories, substations, and outdoor plant areas.
- Car Parks and Open-Air Storage Areas: The 8MP resolution combined with people and vehicle classification enables both wide overview and usable detail at distance, supporting after-hours incident investigation across large unlit areas.
- Municipal and Government Outdoor Installations: Face detection with attributes, people counting, and heat mapping support sites requiring both visual documentation and quantifiable occupancy or movement data across public outdoor areas.
Why Choose the IPC-HFW5842E-ZE
Where a standard bullet camera records what happened, the IPC-HFW5842E-ZE actively analyses it. The combination of 8MP 4K output, a motorized 2.7-12mm varifocal lens adjustable from the NVR interface, and a WizMind analytics engine that classifies faces, people, vehicles, and non-motor vehicles in a single unit is not found in entry-level outdoor cameras at this form factor. The IK10-rated housing adds a physical durability layer that matters in yards, industrial zones, and any site where the camera is mounted at accessible height. The ePoE power option extends cabling distances beyond standard PoE limits, which is practical on large-footprint commercial sites where switching infrastructure cannot always be positioned close to the camera. SMD 3.0 reduces event noise from wind-blown foliage, moving shadows, and small animals, helping operators focus on genuine alerts. Available through Security Wholesalers, the IPC-HFW5842E-ZE suits installers and end users who need 4K image quality and onboard intelligence in a single ruggedised bullet unit.
Buyer Decision Tips
ePoE vs Standard PoE: The IPC-HFW5842E-ZE supports 12V DC, PoE, and ePoE. If the camera is mounting at significant distance from the NVR or PoE switch – such as on a fence post at the far end of a yard – ePoE allows cable runs well beyond the standard 100-metre PoE limit. Confirm your NVR or PoE switch supports ePoE before planning cabling on large-footprint sites.
Storage Planning at 8MP: Running the full 8MP stream at 30 fps with IR, WDR, and all analytics active draws between 10.2W and 12.8W and generates a significantly larger bitrate than a 4MP camera on the same NVR. Enabling Smart H.265+ and using ROI to prioritise bandwidth on high-interest areas of the frame will reduce storage consumption considerably. Size your NVR and HDD configuration with the full analytics load in mind, not just the base stream.

Ideal Use Cases
Perimeter Fence Lines
The 60-metre IR range and varifocal lens suit long boundary sightlines where coverage must extend well past the camera mount point. IVS tripwire rules can be configured to alert on crossings along the fence line without continuous operator attention.
Loading Docks and Delivery Entries
Vehicle classification and loitering detection work together at commercial loading areas, identifying which vehicle types are present and alerting when vehicles or people remain in a zone longer than expected, outside of scheduled delivery windows.
Car Parks and Open Storage Yards
8MP resolution across a wide varifocal angle allows a single mounted unit to cover a substantial area of a car park or outdoor storage yard while retaining enough detail at distance to distinguish individual vehicle types and people after hours.
Industrial and Utility Facilities
The IK10 housing and -30°C to +60°C operating range mean the camera can be wall- or pole-mounted in plant environments, substations, and manufacturing sites where temperature extremes and the risk of physical contact with the camera are ongoing concerns.
Retail and Commercial Building Exteriors
Storefronts, car park entries, and mall loading zones benefit from face detection with attribute capture and 120dB WDR, which handles the contrast between direct sun and shaded entry points that frequently defeats cameras with lower dynamic range.
Public Space and Municipal Monitoring
People counting by area and queue, combined with heat mapping, provides quantifiable occupancy and movement data over time. This suits council-managed public spaces, transit areas, and government facilities where footfall analysis is required alongside standard surveillance.
Choosing the Right Model
- Choose this model if: Your site requires 8MP 4K resolution with onboard WizMind deep learning analytics, a remotely adjustable motorized varifocal lens, 60-metre IR coverage, and a physically hardened IK10/IP67 bullet housing for an exposed outdoor installation. The ePoE power option also makes this suitable for camera positions at extended cable distances from the switch.
- Choose a different model if: Your installation does not require analytics depth beyond basic motion detection, in which case a fixed-lens IR bullet at a lower price point will deliver adequate nighttime perimeter coverage without the WizMind feature set. Alternatively, if full 360-degree or very wide-area overview is the priority at a single mounting point, a panoramic or multi-sensor camera would provide broader spatial coverage that a directional bullet cannot match regardless of lens width.
FAQs
- What does SMD 3.0 do on the IPC-HFW5842E-ZE and how does it differ from standard motion detection?
SMD 3.0 (Smart Motion Detection 3.0) uses deep learning to classify moving objects as people or vehicles before triggering an event, filtering out motion caused by animals, foliage, lighting changes, and shadows. On a perimeter or yard installation where wind and passing vehicles near the boundary would otherwise generate constant alerts, SMD 3.0 focuses event logs on human and vehicle activity only. - Can the motorized varifocal lens be adjusted after the camera is physically mounted?
Yes. The 2.7-12mm motorized varifocal lens can be adjusted remotely through a compatible Dahua NVR interface or the camera’s web interface, allowing installers to fine-tune the zoom and focus angle without accessing the camera physically after it has been secured to a wall, pole, or bracket. This is particularly useful for cameras mounted at height on industrial structures. - What is the difference between PoE and ePoE on this camera, and when does ePoE matter?
Standard PoE (802.3at) limits cable runs to approximately 100 metres from the switch to the camera. ePoE extends this distance significantly, which matters on large industrial sites, perimeter fence runs, or car parks where the NVR or PoE switch cannot be positioned near each camera. If your installation includes long cable runs, confirm that your NVR or PoE switch also supports ePoE before purchasing. - How does the 120dB WDR help at outdoor sites with mixed lighting?
Wide dynamic range at 120dB allows the camera to capture usable detail simultaneously in both bright areas (such as a sunlit car park surface) and dark areas (such as a shaded entry or undercover zone in the same frame). Without sufficient WDR, gate entries with direct sun behind a person and a shadowed foreground typically result in either a silhouetted subject or a washed-out background. - Does the IPC-HFW5842E-ZE support people counting, and how is this useful?
Yes. The WizMind analytics include people counting by defined area, queue, and tripwire crossing. This allows operators to set up zones and receive counts of how many people have entered, exited, or accumulated in an area over a defined period. For retail exteriors, transit hubs, or public spaces this provides occupancy data in addition to standard video recording. - How much storage will an 8MP stream from this camera consume?
Storage consumption depends on resolution, frame rate, scene complexity, and which features are active. At full 8MP with IR, WDR, and analytics running, the bitrate is substantially higher than a 4MP camera. Using Smart H.265+ compression and enabling ROI to allocate higher bitrate only to key areas of the frame – such as a gate or doorway – significantly reduces storage requirements without compromising detail in the monitored zone. - Is this camera in stock, and what is the current lead time?
The IPC-HFW5842E-ZE is not currently held in stock. The lead time is approximately 6-9 weeks. For project planning purposes, orders should be placed with sufficient lead time before the installation date. Contact Security Wholesalers directly to confirm current availability and estimated delivery timing for your order quantity.
