MD-Series Overview

System Description

MD-Series is a maritime thermal imaging system for use on most types of
vessels. The infrared (IR) thermal camera provides night-time imagery, even in
total darkness, based on temperature differences. It provides a clear video image
even under completely dark conditions because it is sensitive to thermal infrared
energy.
The system has a single thermal imaging camera that is available in two models:
• Model MD-324 has a standard resolution camera that supports 2X zoom.
• Model MD-625 has a higher resolution camera that supports either 2X or 4X
Thermal Image at Night
zoom.
Details for each model are listed in "Feature Comparison of MD-Series Models"
on page 55.
The MD-Series consists of a fixed dome assembly, also known as the camera
unit. The camera supplies an analog video output through a standard F-type
coupling, and receives power from its PoE interface.
The MD-Series dome camera is an Internet Protocol (IP) network device. In some
installations, additional cameras, joystick control units (JCU), video equipment,
personal computers, or wireless devices can optionally be used. Networking
equipment such as Power over Ethernet (PoE) switches and routers can be used
to interconnect these components.

MD-Series Dome Assembly

The MD-Series thermal camera is contained in the ball of the dome assembly,
which has a removable cover that protects the camera assembly inside. The outer
dome is not intended to provide camera sealing.
When the cover is removed at the time of installation, the camera assembly can
be mechanically positioned to allow the camera to point in the optimal direction.
The assembly can be rotated up to 30° to either side, and can be tilted -27° to
+34°. The entire camera can also be mounted upside down, known as ball-down
Dome Assembly
installation. See the MD-Series Installation Guide for details about modifying pan/
tilt and installation options.
The thermal infrared camera uses an uncooled vanadium oxide (VOx) detector
sensitive to long-wave infrared (LWIR) thermal energy. The camera detects the
thermal energy that comes from the movement of atoms and molecules that make
up whatever the camera is pointed toward. All objects emit (or radiate) thermal
energy, even cold objects like icebergs.
Ball-Up and Ball-Down Installation
Upside Down
In most installations, the MD-Series is mounted upright on top of a mounting
(Ball Down)
surface, with the base below the camera; this is known as the ball-up orientation.
