<p>An image recording system is installed in a vehicle to enable the driver to have a greater awareness of surrounding events, whilst driving. A number of digital cameras 10 are disposed about the vehicle to capture images in the vicinity of the vehicle. A memory is provided such that these images may be recorded and accessible thereafter for a predetermined period. A monitor (20, figure 7) is located on the vehicle dashboard to enable the driver to observe images captured by the cameras. These are displayed in a split screen format. Furthermore the system comprises a voice monitoring means which compares detected audio signals with stored voice signals to determine whether the vehicle is under threat of break-in etc. If a threat is detected an audible alarm is sounded.</p> |
