AHD 1080P Nitrogen-Filled Anti-Fog Vehicle Camera

Hermetically sealed with positive-pressure dry nitrogen (N₂) to prevent internal lens condensation across extreme temperature drops. Engineered for cold storage shuttle vehicles, IP69K high-pressure washdowns, and heavy industrial fleets—requiring no internal heating element.

Condensation-Free Optics • No Heater Required • Dew Point ≤ -40°C • IP69K

Product Description

The AHD 1080P Nitrogen-Filled Anti-Fog Vehicle Camera is engineered specifically for severe industrial environments where sudden temperature transitions and high-pressure cleaning cause chronic internal lens condensation. Manufactured with a vacuum nitrogen-purged hermetic enclosure, the internal atmospheric dew point is driven below -40°C to permanently eliminate internal fogging at zero operational electrical load.

Key Features

• Hermetic Nitrogen-Purged Sealing (Zero Condensation)：The camera housing is vacuum-evacuated and injected with ultra-dry industrial nitrogen. Maintaining an internal dew point below -40°C, it completely eliminates internal moisture, preventing fogging and lens condensation during abrupt temperature shifts—such as cold storage forklift cycles or steam washdown.

• Split-Optic Isolated Dual Windows (Anti-Glare & Halo Suppression):Unlike conventional single-glass cameras, this model separates the optical lens from the 4-LED illumination array into two sealed circular chambers. This physical barrier prevents internal light bleed, lens flare, and glare reflection during night operation and rain/spray conditions.

• Heavy-Duty Bracket with Calibrated Angle Scale: Engineered with laser-etched degree markings (0° to 90°) and dual stainless-steel hex locking screws on each side. Allows fleet installers to preset and record precise camera tilt angles for uniform field-of-view across identical machinery.

• IP69K High-Pressure Washdown Protection: Precision die-cast alloy body designed to withstand high-pressure steam jets (100 bar, 80°C) and corrosive wash detergents on sanitation trucks, concrete mixers, and heavy machinery.

1080P Low-Light Vision + 4x Matrix IR: 1/2.9" CMOS sensor paired with 4 high-output matrix IR LEDs. Provides clean, noise-free night vision up to 15 meters in pitch-black cold storage.

Technical Specifications

Target Applications

Cold Storage Logistics & Electric Forklifts

Reach trucks frequently cross loading docks into sub-zero freezers. With an internal dew point below -40°C, the lens will not fog from the inside. Zero heater power draw leaves battery runtime unaffected.

Municipal & High-Pressure Washdown Trucks

Waste collection and concrete mixer trucks face daily 80°C hot-water jet washing. Internal micro-positive pressure stops the cooling housing from sucking water past the gaskets.

Agricultural & Heavy Construction Machinery

Dust-sealed, vibration-resistant, and easily adjusted to exact hitch, boom, or chassis sightlines via the calibrated bracket.

Technical FAQ

Q1: Why choose a split-optic camera over a single-glass enclosure?

In single-window enclosures, high-power LEDs can cause internal back-reflection through the glass faceplate, creating a milky haze or white-out glare at night. Split optics physically isolate the lighting chamber from the image sensor, ensuring crisp contrast and zero internal reflection

Q2: Does this nitrogen-filled camera require internal heating elements?

Because dry nitrogen removes all moisture molecules during assembly, the internal air cannot form dew or frost. This eliminates the need for high-draw PTC heaters, saving vehicle battery power while preventing lens fogging completely.

Q3: How does the angle-scale bracket benefit fleet installation?

The laser-engraved degree markings allow installation teams to specify exact mounting angles (e.g., 45° for rear hitch monitoring) across multiple vehicles without trial-and-error alignment.
