Security cameras are more often than not placed in environments where they’re subjected to extreme wind, rain and vandalism. At the same time, it’s critical that the cameras keep working – lives could depend on them.
The cameras need to be robust, and we are proud that customers testify that the cameras we offer are very tough.
4K Ultra HD
A camera that complies with the SMPTE standards indicates adherence to 4K Ultra HD quality and should provide all the benefits of 4K Ultra HD in resolution, color fidelity and frame rate.
4K Ultra HD is based on square pixels—similar to computer screens, so 4K Ultra HD video from network video products can be shown on either HDTV screens or standard computer monitors. With progressive scan 4K Ultra HD video, no conversion or deinterlacing technique needs to be applied when the video is to be processed by a computer or displayed on a computer screen.
Lightfinder technology is a combination of Axis’ expertise in image processing, in-house system-on-chip development and selection of the best optical components.
Cameras with Axis’ Lightfinder technology have extreme light sensitivity. Such cameras can deliver color images in as little light as 0.18 lux or lower.
WDR – Forensic Capture
Axis’ WDR – Forensic Capture optimizes video for forensic purposes by enabling an extremely high level of detail to be visible in both dark and bright areas of a scene. It is the result of years of development at Axis combined with the best imaging components on the market.
An Axis camera with WDR – Forensic Capture applies advanced algorithms to optimize image quality and includes the ability to seamlessly transition between WDR and low-light mode.
Adaptive IR analyzes camera’s captured images and adjusts the intensity of brightness of the camera’s built-in IR LEDs to prevent overexposure of close object images. The SNC-VM772R 4K camera adopts a new version of Advanced IR, which is equipped with two types of IR LED, each for short and long distances, and adjusts them independently to match the zoom setting providing the best IR images with the appropriate exposure even for near and far objects.
View-DR is Sony’s innovative technology to produce images with an extremely wide dynamic range. View-DR is a combination of Sony’s full-capture Wide-D technology, the high-speed Exmor® CMOS sensor, and Visibility Enhancer (VE) technology. The full-capture Wide-D technology in View-DR uses an electronic shutter to capture multiple images and reproduce each frame. One image is taken using a standard exposure time and either one or three images are taken using very short exposure times, depending on the camera type. With the newly developed View-DR algorithm, all of the electrons converted from the captured light are fully used by the imager, which is quite different to some other Wide-D technologies in the industry that discard approximately half of these electrons. As a result, View-DR nearly doubles sensitivity compared to conventional Wide-D technologies. To capture multiple HD resolution images at a very high speed, the Exmor® CMOS sensor is used because of its high-speed readout characteristics. During the process of combining multiple images, the Visibility Enhancer (VE) is employed to provide a high level of chrominance and luminance. With View -DR technology, the monitored image become very visible – sometimes it is even more visible than when viewed with the naked eye.
