Product Overview
Long-range surveillance at a port, coastline, chemical plant or exposed industrial facility requires more than a conventional outdoor PTZ camera. The Hikvision DS-2DT8C842MXG-ELWT combines 8MP resolution, 42x optical zoom and advanced video analytics inside a purpose-built anti-corrosion polymer enclosure. It is designed for locations where salt, moisture and corrosive industrial atmospheres can significantly shorten the service life of standard metal camera housings.
The camera uses a 1/1.8-inch progressive scan CMOS sensor and DarkFighter 2.0 technology to produce detailed video in extremely low light. Its hybrid supplementary lighting system provides infrared coverage up to 500 metres and white-light coverage up to 100 metres. Human and vehicle perimeter protection, multi-target detection, compatible licence plate recognition and Auto-Tracking 2.0 help operators identify and follow relevant activity across large or critical sites.
Key Capabilities
8MP Ultra HD Imaging
Captures video at up to 3840 × 2160 resolution, providing substantially more detail than conventional 2MP or 4MP PTZ cameras. This assists with reviewing people, vehicles and activity across large outdoor areas.
42x Optical Zoom
The 6.0 to 252 mm motorised lens provides 42x optical zoom, allowing operators to investigate distant activity without relying on image-degrading digital enlargement. An additional 16x digital zoom is available when required.
DarkFighter 2.0 Technology
DarkFighter 2.0 supports colour imaging at illumination levels as low as 0.0005 lux under specified conditions. This helps retain useful detail in poorly illuminated industrial yards, transport facilities and coastal locations.
500m IR and 100m White Light
The hybrid supplementary lighting system delivers infrared coverage up to 500 metres and visible white-light coverage up to 100 metres. Smart supplementary-light control helps manage illumination according to scene conditions.
NEMA 4X and C5 Anti-Corrosion Protection
The polymer enclosure provides Hikvision’s top-level anti-corrosion protection and meets NEMA 4X and C5 requirements. It is intended for coastlines, docks, chemical plants and other locations where professional corrosion protection is required.
Deep-Learning Video Analytics
The camera supports simultaneous detection and capture of human bodies, faces and vehicles. Perimeter rules can classify human and vehicle targets, helping reduce alerts caused by unrelated movement.
Best For
- Ports and Wharves: Long-range zoom and a corrosion-resistant polymer enclosure suit environments exposed to salt air, moisture and marine contaminants.
- Chemical and Processing Plants: C5 and NEMA 4X protection make the camera suitable for sites where standard outdoor housings may deteriorate prematurely.
- Transport Infrastructure: The 42x optical zoom supports surveillance across airports, rail corridors, roads, stations and other expansive transport facilities.
- Critical Perimeters: Human and vehicle classification, intrusion detection and Auto-Tracking 2.0 help monitor large boundaries and restricted areas.
- Remote Outdoor Sites: IP67 protection, a working temperature range of -40°C to 70°C and integrated demist and wiper functions support demanding outdoor operation.
Why Choose the DS-2DT8C842MXG-ELWT
The DS-2DT8C842MXG-ELWT is intended for installations where both long-range identification and serious corrosion resistance are required. A standard IP67 camera may resist water and dust but does not necessarily provide protection against sustained salt or chemical exposure. This model combines an anti-corrosion polymer enclosure with 8MP imaging, 42x optical zoom, extended hybrid illumination and deep-learning analytics.
Its integrated analytics support perimeter protection, multi-target detection and intelligent tracking. Vehicle functions include vehicle attribute detection, vehicle counting and compatible licence plate recognition across supported countries and regions. These features make it a capable surveillance platform for high-value infrastructure and expansive sites requiring active monitoring rather than basic video recording.
Buyer Decision Tips
Buyer Tip 1 – Confirm the Corrosion Requirement: This is a specialised industrial PTZ designed for environments requiring top-level anti-corrosion protection. For an ordinary commercial property located away from salt spray or corrosive contaminants, a conventional IP67 PTZ will generally be more economical.
Buyer Tip 2 – Allow for High-Power PoE: The camera requires either 36 VDC or PoE 802.3bt Type 3 Class 6, with maximum power consumption of 60 W. A normal 802.3af PoE switch is not sufficient. Confirm the available PoE budget and individual port capability before installation.
Buyer Tip 3 – Match the Mounting Hardware: Hikvision lists dedicated corrosion-resistant wall, pendant and junction-box mounting accessories for this model. Using ordinary steel brackets in a corrosive environment can undermine the benefit of specifying an anti-corrosion camera.

Ideal Use Cases
Port and Wharf Surveillance
The anti-corrosion polymer enclosure withstands demanding marine conditions, while the 42x optical zoom allows operators to inspect vessels, loading areas and distant sections of the waterfront.
Chemical Plant Security
NEMA 4X and C5 anti-corrosion protection make the camera appropriate for chemically aggressive environments where standard metal camera housings may experience accelerated degradation.
Long-Range Perimeter Monitoring
Up to 500 metres of infrared illumination, human and vehicle classification and Auto-Tracking 2.0 support active monitoring of long fence lines, restricted areas and remote boundaries.
Road, Rail and Airport Applications
High-resolution imaging, powerful optical zoom and compatible vehicle analytics assist operators monitoring transport corridors, terminals and large vehicle movement areas.
Choosing the Right Model
- Choose this model if: The site has severe corrosion exposure and requires long-range 8MP surveillance, powerful optical zoom, extended night illumination and advanced human or vehicle analytics.
- Choose a different model if: The site is a conventional commercial property without salt or chemical exposure. A standard IP67 PTZ will usually provide a more economical solution. A fixed camera may also be more appropriate where active pan, tilt and zoom operation is unnecessary.
FAQs
- Is this an explosion-proof camera?
No. The DS-2DT8C842MXG-ELWT is an anti-corrosion PTZ camera. It should not be treated as explosion-proof or suitable for a classified hazardous area unless the complete proposed installation has the required independent hazardous-area certification.
- How far can the camera see at night?
Its infrared illuminator has a manufacturer-rated maximum range of 500 metres, while the white light reaches up to 100 metres. Actual usable identification distance will depend on zoom position, weather, atmospheric conditions, mounting stability and the amount of light reflected by the subject.
- Can the camera operate near the ocean?
Yes. Hikvision classifies this model as providing top-level anti-corrosion protection for locations such as coastlines and docks. Its polymer enclosure meets NEMA 4X and C5 requirements.
- Does it require a special PoE switch?
Yes. The camera requires PoE 802.3bt Type 3 Class 6 with a maximum power allowance of 60 W. Standard 802.3af PoE and many ordinary 802.3at PoE+ switches will not provide sufficient power.
- Does the camera recognise number plates?
The camera supports licence plate recognition for vehicles and motorcycles in compatible checkpoint applications. Availability depends on the selected country or region, installation angle, vehicle speed, lighting and camera configuration. This feature should be assessed against the intended lane and capture conditions before purchase.
- Can it distinguish people from vehicles?
Yes. Its perimeter protection functions can classify human and vehicle targets for line crossing, intrusion, region entrance and region exiting events, helping reduce alarms generated by irrelevant movement.
- Does it support local recording?
Yes. The built-in memory-card slot supports microSD, microSDHC and microSDXC cards with capacities up to 1 TB. Network storage, including NAS and ANR, is also supported.
- Which mounting brackets are compatible?
Hikvision lists the DS-4602ZJ-GSAC wall mount, DS-4611ZJ-GSAC pendant mount and DS-4680ZJ-GP junction box as optional accessories. The mounting arrangement and substrate must be checked for the approximately 6 kg camera weight and local wind-loading requirements.
