Bullets: a fixed view that survives the weather
A bullet is a fixed camera in a barrel housing, and the two models here add the one thing a plain fixed unit lacks on a ship: a wiper. That combination — fixed aim, cleaned window, IP68 — is what you fit where the view is constant but the weather is not.
Fixed aim, cleaned glass
Both models are specified with a 4.7–94 mm lens and 20× optical zoom, which is unusual for a bullet: the zoom is set once at installation and then left. That gives the installer the ability to frame the view precisely from the mounting point without choosing a fixed focal length in advance.
The wiper is the operational point. Salt film and funnel soot build up on a window within days on some routes, and a fixed camera without a wiper slowly goes blind. Adding the lens washer tank turns that into a self-cleaning unit.
IP68 and what it buys
Both bullets are listed at IP68 — continuous immersion — with 2 or 4 MP sensors and the same Ex d IIC T6 Gb / Ex tD A21 marking as the rest of the range. On a deck that ships green water, that rating is the difference between a camera that survives a passage and one that is replaced after it.
Weight is 6 kg, so the bracket is a standard item. The two models differ in whether IR is fitted: 6 kg either way, but the IR head is longer and needs a clear line to the target.
Where a bullet beats a PTZ
Cost and reliability. A bullet has no pan mechanism to seize, no preset to lose, and it can be aimed exactly where the operator wants it during installation. On a mooring station or a gangway, where the view never needs to move, spending the PTZ budget on two bullets usually buys better coverage.
The limit is that it cannot follow anything. If the activity moves — a crane, a boat alongside, a person walking a long deck — that is the PTZ family, and no amount of wiper makes a fixed camera follow.

Specify it against these four points
- Wiper on both models — the reason to choose a bullet over a fixed camera
- IP68: rated for green water on an exposed deck
- 4.7–94 mm zoom set once at installation for exact framing
- Add the lens washer tank where salt or soot fouling is heavy
Buyer questions
Bullet cameras
Bullet or fixed camera?+−
If the window will foul — exposed deck, funnel area, fishing vessel — the bullet's wiper is worth the difference. In a sheltered position a fixed camera does the same job for less.
Why does a bullet have 20× zoom if it never pans?+−
So the installer can frame the view precisely at commissioning from one mounting point, instead of choosing a fixed focal length and hoping the geometry works out.
Do I need the lens washer as well as the wiper?+−
Where fouling is heavy, yes: a wiper clears water, the washer clears dried salt and soot before the wipe. They are specified as a pair on fishing vessels and near funnel uptakes.
Are the two models different in resolution?+−
Both are listed as 2 or 4 MP; the difference is the IR illuminator. Choose IR where the deck is unlit at night.
