Sony debuts HD security cameras

Face recognition and motion detection applications possible

Sony has unveiled a new range of high definition pan tilt zoom (PTZ) security cameras designed for surveillance and applications such as identification and motion detection.

The SNC-RH series are internet protocol (IP) network security cameras that offer HD surveillance and the ability to pan 360 degrees.

HD images can then be distributed using H.264 video technology at up to 30 frames per second.

Sony Australia’s video security product manager, Tony Lagan, said HD technology suits the security industry well because, although existing cameras give a lot of “floor and ceiling” pictures, HD provides a “nice wide angle”.

“We are increasing the resolution three to four times to gain clearer images and HD provides better facial recognition,” Lagan said.

Lagan said non-HD zoom functions don't provide good picture resolution and digital zoom with HD makes facial recognition possible at the same time as having a wide view.

“There are a lot more applications outside of security,” he said. “We’ve sold large number of cameras for retail applications using analytics technology. The cameras can pick out person loitering in an area, who can then receive a special announcement that the product is on special.”

“Also, analytics can conduct people counting so the retailer can charge suppliers for better positioning. All that is only possible with IP.”

An example of a security application using analytics is capturing people walking in a certain direction or using motion detection to alert a guard who might be responsible for many cameras at once.

According to Sony, the cameras were demonstrated for the first time in the world at the Security 2009 conference in Sydney this week.

The new range includes a power-over-Ethernet model designed for indoor use.
