The IP CCTV product manufacturer IndigoVision has launched the newly enhanced Standard Definition (SD) camera range, including the 9000 range of fixed and fixed dome cameras, complementing the company’s High Definition (HD) and Megapixel (MP) cameras.
Traditionally audio may not have been seen as a priority in the CCTV, the firm says, and as a result most IP cameras use outdated audio encoding, such as G.711 and G.728 compression. These technologies deliver poor quality audio, especially when picking up sounds other than the human voice, such as breaking glass.
Alex Swanson, IndigoVision’s Head of Engineering, said: “People often think of audio in the security industry as being a niche application. Before, most applications for audio were in a police custody type environment but we’re seeing rising CCTV markets, such as Australia and Brazil, using audio more creatively. We’ve had a number of cities in Latin America using the IndigoVision solution as part of “help points” around the city, where citizens can simply press a button to have instant two-way communication with the central monitoring location. Because the audio in our cameras use Advanced Audio Coding (AAC), it means that you can hear much more than the human voice – gunshots, breaking glass or even footsteps. By adding this functionality into more of our IP cameras, it means we’re now meeting the demands of these markets and making it even easier for remote viewing and communication.”
The SD camera range has had video performance improvements resulting in further enhanced video quality and storage cost reduction, the firm adds.
