Dublin Airport is looking to increase use of its 1,400 CCTV cameras to monitor passengers in real time and help improve security and safety.
The Dublin Airport Authority (DAA) has sought companies to provide information on CCTV Video Analytics technology to transform its network of cameras from an "image capture" system to an "intelligent and effective detection and alert" system.
Video Analytics uses IT systems to monitor video in real time, and could be used to identify suspicious behaviour, notify airport management of a passenger falling or to find lost passengers.
The DAA is inviting companies to suggest possible uses for 1,400 cameras in Dublin and 330 in Cork Airport, but there is no commitment to install the technology.
"It's an approach to market. We're asking the industry to come and talk to us," a spokesman said.
"We have significant systems, and if we decided to take the next step (and install the technology), we would go to the market. We're seeing what technologies are available, and are interested in talking to companies who might be operating in other airports."
There was no commitment to buy, and the DAA might decide not to go ahead, he said, adding: "We are on an information-gathering exercise."
Among the advantages is the ability to manage CCTV in real time, and some use facial recognition technology and computer algorithms to identify clothing being worn, which allows passengers to be tracked.
