Those with long memories and rose-tinted glasses will remember Indigovision as one of the great dotcom shares that promised much. Indigovision was a pioneer of CCTV security surveillance systems that used the internet rather than tapes.
Fears that the country was turning into Big Brother, with cameras on every street corner, made the shares very popular. The Edinburgh-based technology company was worth £217m when it floated on the stock market in 2000. Five years on, it is still loss-making and worth £42m.
However, the company looks to be finally delivering on its early promise. Turnover increased by 60pc last year to £3.6m, with some major contract wins including the security systems for the Athens Olympics and the G8 summit at Gleneagles.
The company is due to break even this year. The shares have started to recover and have doubled to 187p over the past five months. However, they are still worth a punt.
