Latin America. Lightning measures the distance between the camera and objects of interest to generate continuously focused images.
Axis Communications developed a technology that allows cameras to calculate the distance to people and objects in the scene, and from that information, accurately focus on points of interest – all in a matter of milliseconds.
Conventional cameras can take some time to adjust the focus automatically in difficult lighting scenarios, such as at dusk or dawn. The new technology already works by sending a transmitter beam and a receiver, generating a focal point reference.
That focus setting performs optimally even in the dark. By having a continuous focal reference, the camera increases its precision in focus and allows you to generate videos with greater detail in low-light scenes.
The laser focus is especially useful in situations that demand the rapid and accurate identification of people and objects, such as on highways and urban monitoring. The technology will be presented by Axis Communications at two major events this September: at the ASIS fair in Orlando, United States, and at the Security Essen fair, in Germany.
"Autofocus is today one of the great challenges for conventional PTZ cameras. Our new laser focus technology allows the camera to measure the distance to objects regardless of lighting," says Sergio Fukushima, technical manager at Axis Communications.
The first camera that has laser focus technology is AXIS Q6155-E, which in addition to having a Full HD resolution and 30x optical zoom, also has other technologies recently launched by Axis: Sharpdome to visualize 20 degrees above the horizon line, Lightfinder to generate images in colors in the dark, and the Speed Dry function to dry the camera simply at the push of a button after the rain.
As in the latest Axis models, the camera comes with Zipstream technology, which reduces the need for bandwidth and storage by 50% on average, while maintaining forensic details.
AXIS Q6155-E camera can be used with the broadest base of video surveillance software in the industry, and supports video analysis applications developed by third parties. ONVIF support allows integration with existing video surveillance systems. The new camera is expected to be available for the fourth quarter of 2016 through axis' dealer network.
