View-DR

View-DR is Sony’s latest Wide-D technology that is used in security cameras to produce images with an extremely wide dynamic range. With View-DR, the camera uses an electronic shutter to capture multiple images, to 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 incident light is captured and converted to electrons by the imager, which is quite different from DynaView™ and some other Wide-D technologies in the industry that discard approximately 1/2 of the electrons. As a result, View-DR nearly doubles the sensitivity compared to conventional Wide-D technologies. To capture multiple HD resolution images at a very high speed, the Exmor™ CMOS sensor was adopted because of its high-speed readout characteristics. During the process of combining multiple images, the Visibility Enhancer is employed to provide a high level of chrominance and luminance. With View-DR, the monitored images become very visible – sometimes even more than when viewed with our naked eyes.

XDNR

XDNR is Sony’s latest technology for noise reduction in IP security cameras. XDNR utilizes 2D and 3D noise reduction methods adaptively to scenes. Under low-light conditions, XDNR provides clear images for both moving objects and still portions of the image, using 2DNR and 3DNR, respectively. This method provides clear images while minimizing motion blur which is a challenge in any outdoor surveillance monitoring applications, such as in parking lots.

DEPA Advanced

The edge devices like network cameras or network encoders with DEPA Advanced technology can trigger an alarm based on user-defined rules, such as “Intelligent Motion Detection” that can detect irregular motion and trigger an alarm, “Tamper Alarm” that detects tampering and triggers an alarm, and “Advanced Audio Detection” that alarms based on ambient sound conditions. This allows users to further refine the criteria for triggering an alarm, making the overall system more efficient.

Ambient Audio Detection

Unlike conventional audio detection where an alarm is triggered based on a preset audio level, the cameras and encoders with this technology trigger their alarms based on ambient sound conditions as the threshold. The cameras and encoders store and update ambient audio levels and frequencies, and when the threshold level based on this data is surpassed, an alarm is triggered.
