Usually, ancient shipwrecks have only preserved cargo, which is mainly amphorae. Amphorae are attractive to thieves because they are easy to steal and quick to sell. Therefore, a security system must be installed before these objects can be presented underwater to visitors. This has to be self-powered, remotely controllable and connected to the network around the clock.

NOUS or uNdersea visiOn sUrveillance System (“NOUS” means “mind” and “intelligence” in Greek) is an innovative prototype system that can continuously monitor a desired underwater area. It combines artificial intelligence for the marine and diving industries, and is eliminating the need for a human operator for tasks such as object recognition, image classification, monitoring and others.

NOUS provides continuous monitoring and protection of an underwater site. On land or on a buoy is a fully autonomous photovoltaic panel system that provides power to the system. Included is a RUT240 router, which provides Internet over the 4G network. Underwater in the form of fiber optic cables.

The underwater section consists of five cameras and a switch. All cameras send video streams to a station via Internet. The image recognition software immediately alerts those in charge if anything unusual occurs and/or poses a threat to the wreck. Any change on site triggers a message so that it can be investigated whether further action is needed.

BENEFITS

• Direct connection of photovoltaic to the router is possible.
• The small size makes it perfect for easy installation where space and weight are limited.
• Operating temperature range from -40 °C to 75 °C and humidity from 10% to 90% make it suitable for use on a buoy.
• Advanced VPN services, including OpenVPN, ZeroTier, Stunnel and many more, ensure data security.
• Compatible with RMS for convenient remote management, real-time data monitoring, analytics and event alerts.
