Overview
IEC 62676-5:2018 is an international standard developed by the International Electrotechnical Commission (IEC) focusing on video surveillance systems used in security applications. This part 5 document specifically addresses data specifications and image quality performance for video surveillance camera devices. It provides a comprehensive framework for describing camera specifications and sets out standardized methods for measuring key performance values. These guidelines are intended to ensure consistency, transparency, and reliability in the technical documentation of surveillance cameras, benefiting manufacturers, integrators, and end-users by establishing clear, objective parameters.
Key Topics
The standard is divided into two main sections:
-
Specification Items for Video Surveillance Cameras
This section defines how performance aspects of camera devices should be described in manuals, brochures, and technical specifications. Key specification items include:
- Image sensor characteristics and maximum resolution
- Minimum illumination and signal-to-noise ratio (SNR)
- White balance, electronic shutter, and slow shutter sensitivity
- Dynamic range (DR) and visible dynamic range (VDR)
- Infrared illumination and day/night mode functionality
- Lens parameters such as focal length, aperture, field of view, and image distortion
- Video output formats and specifications
- Pan and tilt mechanics including rotation angles, speed, and preset accuracy
- Network features encompassing interface types, compression standards, bit rate, frame rate, encoding streams, latency, and security protocols
- Additional features like local camera storage, audio capabilities, and time synchronization
-
Measurement Methods for Performance Evaluation
This section provides standardized methodologies for assessing camera specifications under controlled conditions, ensuring objective comparisons. Measurement topics include:
- Setting up standard shooting conditions for testing
- Video signal quantization levels and environment setup
- Resolution measurement techniques
- Minimum illumination tests and dynamic range assessment
- Visible dynamic range and infrared illumination operating distance tests
- Evaluation of image distortion and flare
- Capture frame rate measurement procedures
The standard also includes normative test charts and informative annexes detailing specialized testing methods, such as low-light performance evaluation, and safety requirements for infrared illuminators.
