Hikvision DS‑2XC3646G0H‑LIZSU(PA) Anti-Corrosion Polymer Vari-focal Bullet Camera 2.7-13.5mm
The Hikvision DS-2XC3646G0H-LIZSU(PA) is a 4 MP anti-corrosion polymer bullet built for coastal and industrial sites. An IP68 polymer housing rated NEMA 4X and C5-M resists salt spray and condensation, while a motorised varifocal lens, AcuSense detection and dual-light night vision keep the picture clear and useful.

§ 01Overview
What the DS-2XC3646G0H-LIZS(PA) is
The Hikvision DS-2XC3646G0H-LIZSU(PA) is a 4 MP (2560 x 1440) anti-corrosion bullet camera, not a 4K camera, built for places that destroy ordinary metal cameras: coastal sites with salt air, water-treatment and chemical plants, and humid industrial buildings.
Its polymer housing carries an IP68 rating against dust and water, NEMA 4X and C5-M anti-corrosion ratings backed by 720 hours of neutral salt spray testing, and an IK10 impact rating, so it keeps working where a standard aluminium camera would corrode and fail.
Behind the tough shell is a capable camera.
A large 1/1.8" sensor with 130 dB Wide Dynamic Range holds detail in harsh, high-contrast light such as a bright loading dock against shaded plant.
AcuSense deep learning classifies people and vehicles and runs perimeter rules that alarm only on those targets, cutting false alerts.
At night a hybrid supplement light reaches up to 50 m, using infrared for a black-and-white image or white light for full-colour where it is wanted.
The motorised 2.7 to 13.5 mm lens sets zoom and focus remotely, so the angle can be framed without opening the housing in a corrosive area.
The camera has a built-in microphone to capture sound alongside the video, a microSD slot and a HEOP open platform for advanced analytics.
It runs on PoE (802.3af) over a single network cable or on 12 VDC.
Record it to a Hikvision AcuSense NVR so the AI events stay searchable.
For an exposed coastal or industrial position, this polymer build is the part that keeps the camera alive.

§ 04Why choose this
Built for the way you actually use the DS-2XC3646G0H-LIZS(PA)
Detection built in
AcuSense classifies people and vehicles and filters out spray, weather and animals to cut false alarms.
Frame it without opening up
A motorised lens sets zoom and focus remotely, so you avoid opening the housing in a corrosive area.
Clear in hard light
A 1/1.8 inch sensor and 130 dB WDR hold detail against backlight and in low light.
§ 05Where it fits
Right at home in these scenarios
Coastal and marine sites
Watch marinas, jetties and seafront buildings where salt air corrodes ordinary cameras.
Water and waste-water plants
Cover tanks, pumps and wash-down areas that stay wet and humid.
Chemical and food processing
Monitor plant where aggressive vapours and regular cleaning defeat standard housings.
Humid industrial buildings
Keep watch in stores and process areas with permanent condensation and pollution.
§ 06Setup
Installation & setup
What's in the box
One DS-2XC3646G0H-LIZSU(PA) bullet camera with an integrated bracket, mounting template, fixings and a quick guide. The PoE switch or NVR, network cable and microSD card are supplied separately.
Installation requirements
Mount it on a wall or post aimed along the area to cover, and run one network cable back to a PoE (802.3af) switch or NVR, or use 12 VDC. Set the zoom, focus and AcuSense rules in the software, and record it to a Hikvision AcuSense NVR. In corrosive areas, seal the cable entry well to protect the connection.

§ 09Bundles
Recommended packages
Record and review it
Feed it to a Hikvision AcuSense recorder such as the 8-channel DS-7608NI-M2/8P NVR, or the 16-channel DS-7616NI-M2/16P for larger sites. Add a surveillance-grade drive like the 8 TB for weeks of continuous footage.
Power it over one cable
Run a single network cable per camera from a PoE source. The HiLook 8-port PoE switch feeds several cameras and the recorder, keeping the cabling tidy on multi-camera sites.
Protect the cable run
In salt or chemical areas the camera survives, but the cabling needs care too. Use marine-grade glands and seal the entry point so moisture and salt cannot track back to the connection.
