Product Overview
Built for perimeter monitoring in environments that standard cameras cannot withstand, the DS-2XC3646G0H-LIZ(S)(U)(PA) is a 4MP anti-corrosion motorised varifocal bullet camera designed for coastal installations, chemical plants, and high-moisture industrial facilities. The polymer anti-corrosion housing is rated to NEMA 4X and C5-M, surviving 720 hours of salt spray and 480 hours of condensation testing. Featuring a motorised varifocal lens in either the 2.7-13.5mm or 7-35mm variant, the field of view can be tuned from broad scene coverage down to long-distance focused monitoring without swapping optics. Equipped with hybrid IR and white light illumination reaching up to 50m, the camera delivers colour imaging in low-light conditions as well as full IR operation when needed. It also incorporates a 1/1.8-inch progressive scan CMOS sensor, HEOP 2.0 support with 1.5 TOPS processing, and a minimum illumination of 0.001 lux at F1.2. This model is well suited to exposed perimeter walls, jetties, processing facilities, and any outdoor site where corrosion is an active concern.
Key Capabilities
Anti-Corrosion Polymer Housing
The polymer enclosure is rated NEMA 4X and C5-M, passing 720 hours of salt spray and 480 hours of condensation testing. This protects camera internals in marine, coastal, chemical, and high-humidity environments where metal housings deteriorate.
Motorised Varifocal Lens
Choose between the 2.7-13.5mm variant (horizontal FOV approx. 107.4 down to 39.8 degrees) or the 7-35mm variant (approx. 40.3 down to 14.5 degrees). Motorised adjustment means the field of view is set remotely during commissioning, removing the need to physically access the camera housing after mounting.
Hybrid IR and White Light Illumination
The dual-mode illuminator combines IR and white light up to approximately 50m, supporting full-colour capture in conditions where white light is appropriate and switching to IR for discreet low-light coverage. The 0.001 lux minimum illumination at F1.2 supports effective imaging in near-darkness.
4MP 1/1.8-Inch CMOS Sensor
The 1/1.8-inch progressive scan CMOS sensor delivers 2560 x 1440 resolution with a maximum F1.2 aperture on the 2.7-13.5mm variant. The larger sensor format improves low-light sensitivity compared to smaller 1/2.7-inch or 1/3-inch sensors commonly found in standard-grade bullet cameras.
HEOP 2.0 with Edge Processing
The integrated HEOP 2.0 platform provides 1.5 TOPS of computing power, 60MB system memory, 371MB smart RAM, and 2GB eMMC storage. This allows third-party analytics applications to run directly on the camera via the Hikvision Embedded Open Platform and OpendevSDK.
Long-Range Directional Coverage
The bullet housing allows the camera to be aimed precisely at a specific approach, fence line, or entry point without wide-angle scatter. Combined with the 7-35mm lens option, it is suited to monitoring long driveways, access roads, jetty walkways, and perimeter corridors from a fixed elevated position.
Best For
- Coastal and Marine Installations: The NEMA 4X and C5-M polymer housing withstands the salt-laden air and moisture levels that corrode standard aluminium or mild-steel housings within months in waterfront environments.
- Chemical Plants and Processing Facilities: The anti-corrosion construction handles chemically aggressive atmospheres where airborne contaminants and fumes would degrade conventional camera enclosures over time.
- Industrial Perimeter Monitoring: The bullet form factor paired with the 7-35mm lens option enables focused coverage of long fence lines, loading dock entrances, and yard perimeters from a single mounted position.
- Sites Requiring Edge Analytics: The HEOP 2.0 platform with 1.5 TOPS of on-board computing supports custom or third-party analytics applications deployed directly on the camera, reducing dependence on centralised processing hardware.
Why Choose the DS-2XC3646G0H-LIZ(S)(U)(PA)
Standard outdoor bullet cameras are not engineered for environments where salt spray, condensation, or chemical exposure are ongoing. The DS-2XC3646G0H-LIZ(S)(U)(PA) addresses this directly with a polymer anti-corrosion enclosure rated to NEMA 4X and C5-M, validated against 720 hours of salt spray testing. A standard IP66 or IP67-rated aluminium housing provides water ingress protection but does not address material corrosion from saline or chemical atmospheres. Beyond the housing, the 1/1.8-inch sensor, F1.2 aperture on the 2.7-13.5mm variant, and hybrid IR plus white light illumination to 50m provide strong imaging capability in the difficult lighting conditions typical of industrial outdoor sites. The motorised varifocal lens allows scope adjustment without physical access to the camera after mounting, which is a practical advantage when cameras are installed at height or in restricted access areas. Available at Security Wholesalers, this camera suits specifiers and installers working on projects where long-term durability in corrosive conditions is a project requirement, not an optional upgrade.
Buyer Decision Tips
Lens Variant Selection: This camera is available in 2 lens variants. The 2.7-13.5mm option covers wider angles (up to approximately 107.4 degrees horizontal) and is better suited to entry points, gate areas, or broader scene capture. The 7-35mm option narrows the field to approximately 14.5 degrees at maximum zoom, making it the correct choice for long fence lines, access roads, or focused distance monitoring. Confirm the correct variant before ordering as this product carries a 6-9 week lead time.
Cable and Conduit Sealing in Corrosive Environments: The anti-corrosion rating of the camera housing is only effective if the cable entry and conduit connections are sealed correctly. In NEMA 4X or C5-M rated installations, use appropriately rated cable glands and corrosion-resistant conduit fittings. Any breach in cable entry sealing introduces moisture pathways that can undermine the camera’s environmental rating over time. Inspect sealing points during commissioning and factor in periodic inspection schedules for ongoing site maintenance.

Ideal Use Cases
Coastal and Port Facilities
Jetty structures, port entry points, and waterfront storage yards expose cameras to constant salt-laden air. The C5-M polymer housing survives 720 hours of salt spray testing, making this camera a practical fit for marine environments where standard housings corrode prematurely.
Chemical and Petrochemical Plants
Airborne chemical vapours and fumes in processing environments corrode standard enclosures quickly. The anti-corrosion polymer housing maintains structural integrity in chemically aggressive atmospheres, and the motorised varifocal lens allows remote zoom adjustment from the control room without accessing the camera.
Industrial Perimeter and Fence Line
The bullet housing directs coverage precisely along fence lines or perimeter approaches. With the 7-35mm lens option narrowing to approximately 14.5 degrees horizontal, the camera provides focused long-distance monitoring of a single corridor or access route from a fixed elevated mounting point.
Outdoor Loading Docks and Yard Entries
Loading areas in industrial sites typically have high moisture, vehicle exhaust, and dust exposure. The NEMA 4X enclosure and hybrid IR plus white light illumination to 50m support clear imaging of vehicle movements and access points through these conditions at night as well as during the day.
Sites Requiring On-Camera Analytics
The HEOP 2.0 platform with 1.5 TOPS of processing and OpendevSDK support allows third-party analytics to run at the edge on the camera itself. This suits remote industrial sites with limited network bandwidth or projects where processing should be distributed rather than centralised at the NVR or server.
Choosing the Right Model
- Choose this model if: The installation site involves salt spray, chemical exposure, or persistent high moisture that would corrode a standard aluminium housing, and you need a motorised varifocal bullet with hybrid illumination and edge processing capability on a single unit.
- Choose the 2.7-13.5mm variant if: The scene requires a wide starting field of view, such as gate areas, building entrances, or broader yard monitoring where initial coverage width is a priority.
- Choose the 7-35mm variant if: The primary monitoring task is long-distance coverage of a specific approach, access road, or fence line where a narrower, more focused field of view is needed from the mounting position.
- Choose a different model if: The installation is a standard indoor or sheltered outdoor environment with no corrosion risk. A conventional IP66-rated bullet or turret camera will meet requirements at a lower cost and without the 6-9 week lead time this anti-corrosion model carries.
FAQs
- What does the C5-M anti-corrosion rating mean for this camera?
C5-M is a corrosivity category defined under international standards for high-corrosion industrial environments, including coastal and offshore zones. For the DS-2XC3646G0H-LIZ(S)(U)(PA), this means the polymer housing has passed 720 hours of salt spray testing and 480 hours of condensation testing. This is a significantly higher durability standard than a standard IP66 or IP67 rating, which covers water ingress but does not address material corrosion.
- What is the difference between the 2.7-13.5mm and 7-35mm lens options?
The 2.7-13.5mm lens provides a horizontal field of view ranging from approximately 107.4 degrees at wide to 39.8 degrees when zoomed in, suited to broader scene coverage. The 7-35mm lens narrows this to approximately 40.3 degrees wide and 14.5 degrees at maximum zoom, providing focused long-distance monitoring. Both are motorised varifocal, so adjustment is done remotely. Select the variant based on the required working distance and coverage width at the specific mounting location before ordering.
- Can the varifocal lens be adjusted remotely after installation?
Yes. The motorised varifocal mechanism allows the zoom and focus to be adjusted via the camera’s configuration interface without physically accessing the housing. This is a practical advantage in industrial installations where the camera is mounted at height, inside a conduit run, or in a restricted access area where hands-on access after commissioning is difficult.
- What is HEOP 2.0 and how does it benefit this camera?
HEOP (Hikvision Embedded Open Platform) 2.0 is an embedded computing environment built into this camera. With 1.5 TOPS of processing power, 371MB of smart RAM, and 2GB of eMMC storage, it supports third-party analytics applications running directly on the camera. This is relevant for industrial sites where edge processing reduces network load or where custom detection logic needs to run without reliance on a central server.
- Does this camera produce colour video at night?
Yes. The hybrid illumination system includes a white light mode which produces colour video in low-light conditions, supplemented by the 0.001 lux minimum illumination rating at F1.2 on the 2.7-13.5mm variant. When the supplementary light is active the effective minimum illumination is 0 lux. The IR-cut filter allows the camera to switch between colour and monochrome IR modes depending on the active illumination mode.
- What cabling and sealing precautions are needed for a corrosive environment installation?
The camera housing is rated for corrosive environments, but the overall installation integrity depends on the cable entry points as well. Use corrosion-resistant cable glands rated to at least the same environmental standard as the installation location, and seal conduit entries properly. In NEMA 4X environments, any unsealed penetration can allow moisture ingress that bypasses the housing’s anti-corrosion properties. Firmware updates are recommended before commissioning, as noted in the installer guidance supplied by Security Wholesalers with this product.
- What is the lead time for this camera and how should I plan for it?
This camera carries a 6-9 week lead time. It is a specialist anti-corrosion product rather than a stocked standard item. For project work, confirm the order early in the procurement phase so the camera arrives in line with the installation schedule. Delaying the order until the installation stage risks holding up commissioning on time-sensitive projects.
