VideoRay Pro 4 Overview
VideoRay is pleased to present the latest model in its top-of-the line professional series Micro-ROVs - the
VideoRay Pro 4. Like the Pro 3, the Pro 4 was designed for performance and maintainability, but has entirely new
internal electronics, including camera, LED lights, processor, and added sensors. With powerful brushless
motors, the Pro 4 further extends VideoRay's position as the fastest and most powerful tether pulling vehicle.
Additional improvements include deeper depth rating, hydrodynamic streamlining, and optimized ballast
adjustment. Topside control is based on industry standard rugged computers, with new software that integrates
several functions while dynamically reconfiguring for ease of use.
The Pro 4 submersible builds on VideoRay's strengths with more than twice the vertical thrust of the Pro 3, and
50% greater horizontal thrust. A depth rating of 300 meters (1000 feet) is standard. Improvements in the
electronics allow for both greater total tether length up to 600 meters (2000 feet) and much better power
transmission over longer tethers. Existing VideoRay tethers can be used with the Pro 4 - and different tether
types can still be combined to meet different operational requirements. New sensors, including 3 axes compass
and accelerometers and MEMS gyro improve navigational capabilities. The primary video camera features ultra
low light and Wide Dynamic Range imaging capability, with a wide range of user controllable parameters for
demanding imaging situations. Coupled with the very high intensity LED lighting, the images and video that can
be captured are far clearer, particularly in difficult lighting conditions. A second camera can be rotated 270
degrees to provide lateral views as needed.
The topside control configuration replaces inflexible and limited switches and knobs with context-sensitive
controls that go beyond simply controlling the submersible to controlling navigation, sonar, image and video
capture, and other sensors and accessories in addition to the submersible. This "systems approach" significantly
reduces operator workload and distraction caused by separate systems for sonar, navigation, video capture, and
vehicle control.
The Pro 4 is part of an industry-wide initiative led by VideoRay (the largest volume ROV manufacturer in the
world) to go beyond separate "point" technology solutions to a "systems" approach to solving underwater tasks.
The Pro 4 series ROVs are packaged in configurations such as the PS (Port Security Configuration) and CD
(Commercial Dive Configuration) designed to solve a specific or series of underwater tasks, with VideoRay
providing comprehensive solutions across the many technologies involved. Users will be able to concentrate on
their underwater missions, not which technology works together and how are the pieces fit together.
Additionally, VideoRay recognizes that technology is only as good as the people who use it. Successful
organizations focus on training and systematic procedures for operations and maintenance. The VideoRay Pro 4
package includes features that help owners and operators develop, implement and execute ROV operations and
maintenance programs more efficiently and effectively. These features include customizable documentation,
online interactive operating checklists and knowledge and skill assessment tools. Companies with one system or
an entire fleet can leverage these capabilities to ensure that their investment in VideoRay equipment continues to
return value throughout its life.
