SHARES in IndigoVision rocketed more than 16 percent yesterday after the Scottish video-networking specialist unveiled record profits and sales on the back of a global shift from analogue to digital surveillance systems.

The Edinburgh-based company, which is listed on the Alternative Investment Market and for several years has remained one of Scotland's technology hopefuls, posted a pre-tax profit of GBP2.04m for the year to the end of July, almost treble the GBP680,000 pre-tax profit it posted the previous year.

Marcus Kneen, Indigo's chief financial officer, yesterday enthused: "Our profits have been rising pretty fast over the past couple of years, but more than GBP2m is really something else. That's a real profit."

At the same time sales surged 37per cent to GBP18.4m, compared with GBP13.4m a year earlier.

Indigo, which employs 55 of its 118-strong global staff in Scotland, has reinvented itself since 2003, when its share price tumbled below 30p, changing its business model from licensing its technology to becoming a manufacturer and distributor.

Its shares peaked at more than 1000p last year - but they have been hit hard during the market volatility of the past 12 months.
