Water safety device

A safety device, the device comprising:

• at least two video camera systems with lenses arranged at a horizontal level around a periphery of the safety device adapted to float on water such that a water level reaches approximately to the mid-point of the lenses, each camera having a field of view that extends both vertically and horizontally;
• an accelerometer arranged to generate a voltage signal in the event that the safety device experiences an accelerating force;
• a transceiver that enables two-way wireless communication between the device and a network;
• a processor in communication with the accelerometer, transceiver and camera systems and that includes an image analysis module;
• the processor being arranged such that:
• (a) on receipt of a first voltage signal from the accelerometer that exceeds a threshold value, the processor causes the safety device to enter an analysis mode in which:
• power is supplied to the camera systems such that each generates an image of its field of view;
• and
• the image analysis module is arranged to analyse image data generated by the camera systems to determine classification of an event recorded in the data and, in response to the classification determination, either:
• (b) to return the device to a standby mode in which power is no longer supplied to the camera systems;
• or
• (c) to cause the safety device to enter an alert mode in which an alert signal is transmitted via the transceiver to a remote device.
