PTZ: the camera that follows the work
A pan-tilt unit is what you fit when the activity moves — a crane working a hold, a gangway in use, a boat coming alongside. The four models here share the same 360° continuous pan, the same 20× optical zoom and the same wiper; what differs is the arm and whether IR is fitted.
The shared platform
All four units are specified with a 360° continuous horizontal rotation and a vertical range from +90° down to −90°, at 8°/s with medium speed selectable between 0.1–20°/s and high speed 0.1–35°/s. The lens is 4.7–94 mm with 20× optical zoom, and 25× or 30× variants are listed as custom options.
Every one of them carries a wiper, which is the reason this family exists on a ship: a PTZ left pointing into weather collects salt on the window, and a wiper is what turns a useless picture back into a usable one. Power is AC 220 V at 75 W maximum, and the housing is IP66 in SUS 304 or 316L.
Single arm, dual arm, with or without IR
The four models differ in the mounting arm and the IR illuminator. The single-arm versions mount on a vertical post or a wall bracket with the camera hanging from one side; the dual-arm version supports the housing from both sides, which is the choice for a heavy unit on an exposed mast where vibration would fatigue a single joint.
The IR variants add illumination for night work. If the deck has floodlights the non-IR unit is lighter and cheaper; if the camera has to see into an unlit hold or over the side at night, fit IR and accept the extra head.
What a PTZ demands that a fixed camera does not
Presets and a control path. A PTZ that nobody can drive is an expensive fixed camera, so the recorder and the operator station are part of the specification: who sets the presets, how the joystick reaches the camera, and what happens when the link drops. On a vessel the practical answer is usually a small NVR on the bridge with local control.
Maintenance is the other half. A wiper blade and its motor are the parts that fail first, and they sit on the outside of a housing in the worst weather on the ship. Ask about the wiper as a service item before you buy four of them.

Specify it against these four points
- 20× optical zoom (4.7–94 mm); 25× and 30× listed as custom
- Wiper on every model — budget the blade as a service part
- Single arm for posts and walls, dual arm for exposed masts
- IR variant only where the deck lighting is not enough
Buyer questions
PTZ cameras
Do all PTZ models have a wiper?+−
In this family, yes — the wiper is on all four units, which is why the model names all read "wiper". The difference between them is the arm and the IR illuminator.
Is 20× zoom enough on a large deck?+−
At 4.7 mm the unit covers a wide area; at 94 mm it identifies detail across a deck. Where more reach is needed the catalogue lists 25× and 30× as custom options — ask for the field-of-view table at those focal lengths before deciding.
Can the PTZ be driven from the bridge?+−
That is a control-path question, not a camera one: the unit accepts serial control and the recorder or joystick has to reach it. Specify the control protocol with the NVR rather than after the cable is pulled.
Single or dual arm?+−
Dual arm where the housing is on an exposed mast and vibration is continuous; single arm on a wall or post where the load is carried from below. The dual arm costs more and solves a fatigue problem, not a functional one.
