The CCTV industry in the UK has a turnover of £600m a year
Surveillance experts from all over the country are in Newcastle looking at ways of using the technology to fight crime and anti-social behaviour.
It is thought there are over 1.5m public space CCTV cameras in operation in Britain.
Safe Newcastle, which is co-hosting the conference on Tuesday, has championed the use of CCTV to help cut crime.
A spokesman from the group said it had introduced 30 mobile cameras to augment fixed CCTV across the city.
The event will look at the greater co-ordination of CCTV systems between various operators, better use of cameras and the long-term development and strategic use of surveillance equipment.
Over 50 exhibitors are showcasing the latest technology and equipment used in surveillance operations at the Gosforth Park Marriott Hotel in Newcastle.
