Fires are common in South Africa\\u2019s informal settlements - it\\u2019s estimated that there are about 5,000 every year. They\\u2019re often caused by faulty wiring or open flames used for cooking or heating. Because the shacks are crammed in so tightly the flames can spread with frightening speed and destroy hundreds of homes. \\nSo a group of entrepreneurs invented a smart fire alarm for just these sorts of places. It has a sensor that spots fast increases in heat and then sends alerts to all the neighbours so they can quickly take action. They also designed insurance to help people who are affected by these fires rebuild and replace what they\\u2019ve lost. We go to one of these settlements in Cape Town and find out what difference it has made to the lives of the people living there.\\nReporter: Richard Kenny
