Axis 02578-001 TM3818 Black Dome Camera Casing 4-Pack
Overview
The Axis 02578-001 is a replacement dome casing kit containing four black aluminum covers designed specifically for Axis IP cameras in the M3085-V and M3086-V lines. This accessory addresses a straightforward deployment need: protecting your fixed dome cameras from environmental exposure and physical impact while maintaining a clean, professional appearance across your surveillance installation.
Key Features
- Material — Aluminum Construction: Each cover is machined from aluminum, which resists corrosion and UV degradation far better than plastic housings. This matters in outdoor or high-humidity environments where dome covers experience repeated thermal cycling and salt spray exposure. Aluminum also dissipates heat more effectively, reducing condensation buildup inside the dome.
- Weight — 0.5 lbs per Cover: At just half a pound each, the TM3818 casings don't add significant load to your camera mounting bracket or ceiling surface. This is relevant when deploying multiple cameras on shared conduit or thin-wall fixtures where cumulative weight becomes a structural concern.
- Color — Black Finish: The matte black coating provides visual consistency across installations. It blends into ceiling tiles, wall surfaces, and architectural elements better than chrome or white alternatives, reducing visual clutter in open office, retail, or warehouse environments.
- Compatibility — M3085-V and M3086-V: These casings fit only Axis M3085-V and M3086-V models. Before ordering, verify your installed camera model — using the wrong cover size can crack the dome or leave gaps that allow dust or insects to reach the lens.
- Package Quantity — Four Covers: The 02578-001 ships with exactly four casings, allowing you to refresh covers across a small cluster of cameras in one order or maintain spares for quick field replacement when a dome becomes abraded or cloudy.
- Protective Benefit — Vandalism and Impact Resistance: Aluminum dome covers reduce the risk of lens scratches, accidental strikes, or deliberate tampering compared to leaving the camera dome exposed. They do not guarantee protection against determined attack or significant impact, but they raise the barrier for casual damage.
Integration & Compatibility
The TM3818 cover (02578-001) mounts directly over the existing camera dome using the factory attachment mechanism on the M3085-V and M3086-V. No tools or modifications are required — simply slip the casing over the camera head and secure according to Axis installation guidance. If you are deploying dome IP cameras from other manufacturers or own different Axis models, confirm compatibility with the camera's OEM documentation before purchasing.
When to Choose a Different Accessory
If your M3085-V or M3086-V cameras are installed indoors in a climate-controlled environment with minimal dust or physical contact risk, a replacement casing may not be necessary. Conversely, if your cameras face direct sunlight, salt spray, or high-impact zones (e.g., near loading docks or industrial equipment), verify that the aluminum TM3818 cover meets your environmental rating requirements — it provides physical protection but is not rated for submersion or extreme pressure washdown scenarios.

Frequently Asked Questions
Q: Will the TM3818 cover fit my Axis M3044-WV or M3045-WV camera?
A: No. The 02578-001 covers are designed specifically for the M3085-V and M3086-V models. Using them on other camera models may result in a poor fit or optical interference. Always verify compatibility with your camera model number before ordering.
Q: Does the aluminum dome reduce the camera's field of view?
A: The TM3818 cover is engineered to mount over the existing dome lens assembly without blocking the optical path. However, any external cover will add a slight optical surface. If you require maximum light transmission or wide-angle coverage, consult Axis specifications to confirm any minor loss is acceptable for your deployment.
Q: Can I install the TM3818 cover on a camera that is already mounted and powered on?
A: Yes. The casing is a passive mechanical accessory with no electrical connections. You can install or swap covers without powering down the camera or disrupting video streams. However, exercise caution near the lens and mounting hardware to avoid accidental contact with active equipment.
Q: How often should I replace the dome cover?
A: Replacement frequency depends on environmental exposure. In high-dust or outdoor environments, inspect the cover every 6–12 months for cloudiness, scratches, or discoloration. If optical clarity is visibly compromised and cleaning does not restore it, replace the cover. Indoor installations may go several years without replacement.
Q: Are the TM3818 covers sold individually or only in 4-packs?
A: The 02578-001 is a 4-pack. If you need a single replacement cover or a different quantity, contact Axis or your specialty distributor to check for alternative SKUs.

The Axis 02578-001 is not a camera — it's a consumable protective accessory. If you're replacing dome covers on M3085-V or M3086-V systems, the aluminum TM3818 is a straightforward spec match. The 0.5 lb weight per cover is negligible on any standard ceiling or pendant mount, so installation labor is minimal.
Technical Highlights:
- Aluminum Material: Resists corrosion and UV better than ABS plastic. Matters most in outdoor, salty, or high-humidity settings where plastic becomes brittle within 18–24 months. Aluminum extends useful life to 3–5+ years in moderate conditions.
- Four-Pack Quantity: Enough to cover a small camera cluster or maintain spares for reactive field replacement. If you're rolling out covers to a larger installation, calculate packs needed upfront — stockouts delay refresh cycles.
- Black Finish: Reduces visual distraction in white-ceiling or finished-space deployments. Dust shows more readily on black, so budget for occasional cleaning if aesthetics matter to your end customer.
Deployment Considerations:
- Verify camera model before ordering. M3085-V and M3086-V only — using the wrong size wastes time and money. Axis does not publish cross-compatibility matrices for dome covers, so field confirmation is your responsibility.
- Optical impact is minimal but present. If your M3085-V or M3086-V is at the edge of its specified horizontal field of view and you need every degree, test the cover on a spare unit before rolling it across your fleet.
- Aluminum covers require periodic inspection in dusty or outdoor environments. A cloudy cover can degrade image quality as much as a scratched lens — plan for 6–12 month replacement cycles if the camera faces direct weathering.
Deploy the 02578-001 where dome protection is a preventive measure: retail stores with high foot traffic, warehouses prone to dust and forklift vibration, or outdoor installations facing salt spray or UV exposure. Skip the cover if your cameras are indoors on stable mounts in low-risk settings — you're paying for protection you don't need.
