cNODE Mantis

An exciting new addition to the cNODE product range of acoustic modems which introduces the new capability to stream a live video feed for a variety of subsea installation tasks.

Having established itself over the years as an acoustic positioning system of unmatched reliability and robustness, the cNODE has set the standard for subsurface operational technology. The same principles of technical innovation and tough build quality have been brought to bear in the expanded functionality of the cNODE Mantis: the addition of a live video solution significantly increases the number of applications and services for which cNODE systems could be used.

An brief introduction to cNode Mantis

The full potential of the cNODE Mantis as ‘a second set of eyes’ in this respect is easily realised. The live video it streams is transmitted to a receiver installed either on the ROV’s TMS (Tether Management System) or on the vessel itself, at ranges of up to 500m. As the wireless video transfer works on a high-speed acoustics link it will function in both murky and clear water conditions and is unaffected by background light. With a bit-rate of up to 70 kbit/s, it allows for the transfer of live video with a typical quality of 420 x 380p at four frames per second.
