Wireless video / com system

In 2014, LH Camera was contacted by a Norwegian company that wanted to develop a wireless video / communication system for their divers. The task was to provide a system that could provide video and communication between a number of divers in the water and a surface boat so that everyone could communicate with each other. Each diver had to have a video camera mounted so that the surface boat could see live footage from each diver. At the same time, the system had to meet the safety requirements for commercial diving.

Based on the project, we are now pleased to be able to unveil a world first: A system with a surface station with built-in cordless diving telephone, which can send to and receive from each diver at a distance of up to approx. 500 meters, as well as wireless video signal receivers with a range of approx. 100 meters from each diver, which can be displayed on a monitor with split screen function. All parts are mounted in a portable video / com case with control panel for video and communication.

Each diver is equipped with a full-face mask with voice / listening module plus holder for underwater camcorder. Video and communication are transmitted via a lifeline with cable and floating inserts mounted in the diver’s harness and connected to a floating waterproof surface buoy in which transmitting equipment for video and communication is mounted.

The system is intended for commercial diving, where you need to perform a safe underwater task without surface supply and at the same time maintain communication and transfer of live images to the surface.

Technical data on wireless video / com system

  • Surface station case with built-in 15 ″ sun-readable monitor with split-image function of 4 divers. Built-in speaker push to talk and speaker. Built-in wireless com unit and wireless video receiver with the option of connecting an external antenna. Option for built-in video recorder.
  • Robust surface buoy with weight pendulum in stainless steel that provides good stability, as well as an eye with carabiner for connecting a diving lifeline. Built-in waterproof container with wireless transmitters for video and diver communication. Rechargeable battery with an operating time of approx. 2 hours for camcorder and 10 hours on the diver communication.
  • Diving lifeline, in which there is a cable for video and data (for eg depth sensor) as well as a separate communication cable. Both cables are fitted with connectors for camera and voice / listening module as well as subconnector connection for surface buoy. The cables are braided in a polypropylene sock, which has a breaking strength of 380 kg. The sock has floating inserts so the line is positive in water.
