A recession-driven surge in shoplifting and fraud at casinos helped fuel a 43 per cent increase in sales to £26.4m at IndigoVision, which provides internet-based digital camera security systems.

Shares in the Edinburgh-based company were unchanged at 715p after it reported a 60 per cent jump in pre-tax profits to £3.26m (£2m) for the year to July 31 and said it would pay a maiden 5p dividend.
