Hikvision has integrated seven advanced technologies that drive stability, precision, and efficiency in video monitoring with Pan-Tilt-Zoom (PTZ) cameras. In this blog, we’ll explore how these innovations—such as image stabilization, rapid focusing, and dual-view capabilities—enable Hikvision’s PTZ cameras to provide unmatched performance in various environments.
Numerous real-world challenges face security professionals who need to deliver reliable and efficient video monitoring solutions. Sometimes, it is finding a way to focus on critical issues that occur within a video stream. At other times, they need to be able to ‘see’ in very adverse weather conditions. To cope with these different challenging scenarios, security solutions must be able to adapt and respond with precision and intelligence. Hikvision’s PTZ cameras bring together dedicated technologies designed to address these needs, ensuring optimal performance in the most demanding conditions.
7 innovations that enable Hikvision’s PTZ cameras to be trusted in diverse real-world scenarios
1. Stabilizing images against vibrations
When PTZ cameras are installed on bridges or in areas with strong winds, they are prone to vibration. This can cause the image to show signs of shaking, especially when the lens is extended to its maximum focal length. To address this problem, Hikvision has developed unique Optical Image Stabilization (OIS) and Gyroscope Image Stabilization (GIS) technologies for its PTZ cameras. Both technologies use a gyroscope to detect and measure camera vibrations. The OIS technology compensates for the camera motion by moving the lens in the optical path, ensuring that the lens always stays focused on the sensor. The GIS technology, meanwhile, counterbalances the camera's motion digitally.
2. Seeing through fog
When monitoring long distances, fog can be a significant issue. Hikvision's defog technology measures fog density based on the level of grayness in the live video feed and automatically activates a proper defog mode. In light fog, the Algorithmic Defog mode enables the camera to digitally recover and enhance image details to produce colored video. In more challenging, thick fog conditions, the Optical Defog mode is activated. This mode uses infrared light, which can penetrate the fog to generate black-and-white video. Despite the absence of color, the video is of high quality thanks to advanced Image Signal Processing (ISP), which significantly reduces noise.
