Aperçu de conformité

Cet aperçu n’est actuellement disponible qu’en anglais.

Champ d’application

This standard applies to the production and inspection of digital video recording equipment (DVR) used specifically for security and protection purposes. It covers devices designed for video surveillance, including basic, professional, and comprehensive types of DVRs. It is mandatory for manufacturers producing surveillance digital recorders for the Chinese market. Digital audio/video recording equipment used in other application fields may refer to this standard.

Exigences techniques

The standard classifies DVRs into three categories (Basic, Professional, Comprehensive) and two grades (A and B) based on image quality and resolution. It mandates specific requirements for software and hardware design, ensuring systems possess Chinese language processing capabilities, self-diagnostic functions, and modular hardware designs. Manufacturers must clearly declare the product's classification, grade, and total resources in their technical documentation. Regarding electromechanical performance, the standard sets strict environmental adaptability and electromagnetic compatibility (EMC) requirements. Devices must withstand specific temperature, humidity, vibration, and shock levels, alongside EMC immunity and emission tests. Devices must demonstrate robust safety features, including specific limits for insulation resistance, dielectric strength, and leakage current. For functional performance, the standard specifies critical operational features such as full-duplex recording, video intrusion detection, alarm linkage, and pre-recording before an alarm event. It also dictates strict parameters for video image quality, requiring both objective testing (resolution, frame rate, signal-to-noise ratio) and subjective evaluation. Devices must ensure data security through operation authorization, encryption, and tamper-proof measures.

Méthodes d’essai

Testing involves a comprehensive evaluation of both electromechanical performance and functional capabilities. Environmental adaptability tests include high/low temperature operation, constant heat and humidity, shock, and vibration. EMC tests evaluate immunity against electrostatic discharge, radio-frequency fields, and surges, alongside radiation and conduction emission measurements. Functional tests rigorously evaluate image quality using both objective metrics and subjective 5-level scoring systems tailored to security scenarios.

Questions fréquentes

What products are regulated under GB 20815-2006?

It regulates digital video recording equipment (DVR) used specifically in security and protection systems, including basic, professional, and comprehensive types. It is mandatory for DVRs intended for the Chinese security market.

How does GB 20815-2006 classify and grade DVR products?

It classifies DVRs into B and A levels based on image quality. Level A requires higher resolution (≥704x576 pixels), a signal-to-noise ratio of ≥35dB, and higher horizontal definition for both monitoring and playback. Manufacturers must declare their product's classification in technical documentation.

How does GB 20815-2006 differ from international ISO or IEC standards?

It incorporates relevant IEC standards for electromagnetic compatibility (e.g., IEC 61000-4 series) and ISO standards for packaging. However, it establishes unique, stringent subjective evaluation metrics tailored to security scenarios, such as recognizing banknote counting and vehicle license plates under various conditions. Compliance requires meeting these specific Chinese evaluation criteria.

The summary above provides a high-level overview of GB 20815-2006.
