Dome · 2 models
Domes: the widest field from the smallest housing
A dome hides its lens behind a curved window, so it can look down and outward from a ceiling or a mast head without a protruding barrel. The catalogue lists two, and they are not the same camera at two prices — one is a compact fixed dome, the other a zoom dome with a 23× optical range.
Two domes, two jobs
The IP68 unit is the general-purpose one: 2 or 4 MP, 2.8 / 4 / 6 mm lens options, 50 m IR, 4 kg. It is what you fit in a corner of a pump room, over an access hatch, or under a deck overhang where a barrel camera would be knocked.
The IP66 unit is a different animal: 4.8–110 mm with 23× optical zoom, 50 m IR, 12 kg. That is a surveillance camera with reach — it can cover a wide area at 4.8 mm and identify a person at 110 mm, from the same mounting point. The weight and the larger housing follow from the optics.
Why the ingress rating differs
The zoom dome is listed at IP66, the compact one at IP68. Both are jet-resistant; IP68 adds continuous immersion, which matters for a camera that can be washed down or submerged by green water on an exposed deck.
That difference is not a marketing detail — it decides where each unit may be mounted. Put the IP68 dome where the deck floods; the IP66 zoom dome belongs under a structure where spray reaches it but standing water does not.
Specifying a dome well
Domes are usually chosen for aesthetics and vandal resistance, but on a vessel the deciding factor is the window. A curved polycarbonate or glass dome picks up salt film faster than a flat window, and there is no wiper on either model here — so budget for the lens washer or a scheduled manual clean on any dome that faces weather.
Check the mounting too: the catalogue lists ceiling, wall or desk mounting for the compact unit and a cylindrical pendant mount for the zoom dome. On a vessel that means the bracket is part of the civil work, not an accessory.

Specify it against these four points
- IP68 compact dome for decks that flood; IP66 zoom dome under cover
- Zoom dome: 4.8–110 mm, 23× optical — wide area and identification from one point
- No wiper on either — plan the lens washer or a cleaning schedule
- Pendant versus ceiling mount decides the bracket and the cable route
Buyer questions
Dome cameras
Can the zoom dome replace a PTZ?+−
It zooms but does not pan or tilt. If the camera must follow activity across a deck, that is the PTZ family; if it must look at a fixed sector with variable zoom, the zoom dome is the cheaper way to get reach.
Why is the IP66 dome heavier than the IP68 one?+−
Optics. The 23× zoom mechanism and the larger housing account for 12 kg against 4 kg for the compact dome — which changes the bracket and the wind load, not the camera electronics.
Do domes fog up?+−
The catalogue does not specify a heater or blower. On a vessel moving between climate zones, ask the manufacturer about anti-condensation before fitting a dome in a humid space.
Which one for a hazardous cargo hold?+−
Both are published with the same Ex d IIC T6 Gb / Ex tD A21 marking, so the choice follows the environment — flooding, mounting height, zoom need — rather than the marking.
