The Chinese video surveillance products manufacturer Hikvision has introduced a range of 4K surveillance products.
The 4K Total System features the company’s H.264+ Smart Codec, which reduces bandwidth and storage requirements by half, it’s claimed, compared to standard H.264 codecs while maximising video resolution.
The new 4K family includes ultra-high definition network cameras and network video recorders, all with a variety of Smart functions. The makers say that the products are for applications requiring high-resolution images and surveillance of large areas such as stadiums and car parks.
The company points to concerns about the burden placed on the transmission system and storage when CCTV cameras and NVRs lacking dedicated 4K-compatible components are installed. This is not an issue with the 4K Total System, which incorporates H.264+ optimised compression to allow users to more efficiently manage high definition video. With features such as background-based predictive smart encoding, enhanced noise suppression, and optimized bitrate control, Hikvision says that its H.264+ compression saves bandwidth resources and decreases storage requirements.
Output
The 4K network recorders (NVRs) support the HDMI 2.0 output interface, allowing users to display 4K video for monitoring applications. The 4K IP dome, bullet and box cameras with a variety of 4K NVR models, delivers Ultra-High Definition (UHD) images, providing 4K resolution in real time. The images also improve video analytics performance, particularly in scenes covering large areas. Limited resolution has been hindering video analysis, the firm says, but now the additional pixels in 4K technology allow for better resolution and improved image enhancement, which in turn allow for more information to be extracted from the scene.
Features
As a part of the Hikvision Smart product family, the new 4K products are equipped with smart features such as face detection, intrusion detection, line crossing detection, and smart focus. Smart tracking capability enables the cameras to detect any progressively moving object and follow it within the camera’s area of coverage, while Smart video analytics includes region enter/exit, object left behind and object removed.
