Forum Energy Technologies (FET) has released its latest generation of video recording solutions for the survey and inspection of subsea assets.

Version 11 (V11) of VisualDVR, a digital video recorder produced by FET’s VisualSoft product line, marks a major step forward for the technology’s capability and user experience.

VisualSoft was originally launched in the early 2000s and has continued to be at the cutting-edge of developments in the technology.

Similar to its predecessors, VisualDVR (V11) is a multi-channel, rack mountable digital video system designed for use on remote operating vehicles (ROVs), supporting activities in the energy, defence and ocean science sectors.

The system can record up to four channels of HD video at 1080p/60fps from HD-SDI sources and is equipped with a host of tools and complementary applications to support real time documentation of the video images with data from subsea sensors and inspection personnel.

As with the legacy VisualDVR system, files are encoded using H.264 format. A new higher compression option, H.265, is now included.

As part of the update, V11’s user interface which has been completely modernised. Configuration of recording quality, data paths, input and output profiles can be accessed easily, and channels can be developed in a simple step-by-step process.

There are new tools to flag potential setting conflicts while improvements have been made to allow video overlay set up to be simpler.

The new system is supported by new hardware architecture. A proficient motherboard and high-end graphics card have been chosen alongside a leading-edge multi-channel video encoder card that has been selected for optimum performance and reliability.

In addition to this, VisualDVR can now stream each channel of overlayed video over a network using UDP. A free network player will be available to allow these video streams to be easily viewed.

According to VisualSoft, it is expected that subsequent releases in the coming months will include a capability to stream video using an alternative protocol and also to output an HD-SDI signal using H.265. Testing of these options is currently ongoing while the ability to accept video from IP camera sources is in the test pipeline.

Andy McAra, FET’s product director, said: "Our technology takes into consideration the challenges we may face in supply chain, and we believe any necessary changes to our hardware architecture will be more easily implemented than with our legacy system."
