Recently, Hikvision officially rolled out a range of products that adhere to the industry standard “Technical Requirements for the Construction and Networking of Video Surveillance Systems for Self - Monitoring by Pollution Discharge Units”. Encompassing a comprehensive suite of products including front - end cameras, Digital Video Recorders (DVRs), and video data aggregation systems, these offerings deliver dependable technical support to ecological environment departments. This support enables them to enhance their oversight of monitoring activities and crack down on data fraud.

With the thorough enforcement of laws and regulations like the “Ecological Environment Code” and the “Regulations on Ecological Environment Monitoring”, there's an urgent demand within the industry to standardize the construction of video surveillance systems for self - monitoring by pollution discharge units. The products launched by Hikvision are built around the core tenets of “intelligence, tamper - resistance, and transparent supervision”. They make use of cutting - edge technologies such as Guanlan encoding, true full - color imaging, large models, and dual - stream storage. These technologies aid in establishing a closed - loop off - site supervision system that features “process documentation—anomaly alerts—evidence fixation”.

When it comes to camera products, by harnessing Guanlan encoding technology and large model scene understanding with texture encoding, they guarantee high - quality imaging of important targets. At the same time, they achieve over 50% savings in storage space in real - world project applications. The true full - color 2.0 technology utilizes an F1.0 ultra - large aperture lens and a 1/1.8" back - illuminated sensor. Combined with 3D Look - Up Table (LUT) and 4x AI noise reduction, it significantly boosts the quality of nighttime images. Moreover, these products are equipped with intelligent detection algorithms for video loss, obstruction, intrusion, and tripwire events, enabling swift identification of anomalies.

For DVRs, a dual - stream storage architecture is employed. The main stream ensures 90 days of continuous recording, while the sub - stream meets the one - year storage requirement for personnel activities. A minute - level heartbeat mechanism actively transmits heartbeat packets every 60 seconds, effectively guaranteeing the availability and integrity of videos. The tamper - proof design follows the principles of “no deletion, minimum privileges, and least authorization”, preventing unauthorized users from accessing system files or making operational changes to the devices.

The video data aggregation system supports multi - level video cascading at the national, provincial, and municipal levels. It offers core functions such as front - end device access, historical video playback, log record queries, online rate queries, video quality diagnostics, and intelligent analysis. It also allows for the expansion of capabilities, including alarm event statistics, intelligent alarm rotation, and multi - dimensional retrieval.
