Introduction
As video surveillance systems continue to evolve toward higher resolutions, AI-driven analytics, and cloud-based architectures, video compression efficiency has become a critical factor in system performance.
Traditional codecs such as H.264 and H.265 (HEVC) remain widely used in the security industry. However, increasing demands for 4K/8K video, multi-stream transmission, and long-term storage are driving the need for more efficient and scalable compression technologies.
AV1 (AOMedia Video 1) is a next-generation, royalty-free video codec designed to significantly improve compression efficiency while maintaining high visual quality.
Why Video Compression Matters in Surveillance
Video compression directly affects the performance and cost efficiency of surveillance systems:
Network bandwidth usage in multi-camera deployments
Cloud transmission efficiency for remote monitoring
Storage requirements in NVR/VMS systems
Video quality under limited bitrate conditions
Scalability of large-scale surveillance infrastructures
As resolution and AI workloads increase, efficient compression becomes essential for system scalability.
What is AV1
AV1 is a modern video codec developed by the Alliance for Open Media (AOMedia), a consortium founded in 2015 by leading technology companies including Google, Amazon, Microsoft, Apple, Mozilla, Netflix, NVIDIA, Intel, and Cisco.
Officially released in 2018, AV1 is an open-source and royalty-free video compression standard designed for efficient video delivery across internet and cloud-based platforms.
It is widely adopted in major streaming services such as YouTube, Netflix, and Amazon, demonstrating its maturity in large-scale real-world applications.
Why AV1
AV1 introduces a new generation of compression efficiency designed for modern video workloads.
Higher Compression Efficiency
AV1 delivers better compression than H.265, reducing bitrate while maintaining high video quality. This improves bandwidth efficiency in multi-camera and remote surveillance scenarios.
Lower Storage and Operational Cost
Reduced bitrate translates into lower storage consumption and extended recording retention, helping reduce overall system cost.
Cloud-Optimized Architecture
AV1 is designed for modern cloud and streaming environments, enabling more efficient video transmission and improved performance in remote monitoring applications.
Open and Royalty-Free Standard
As a fully open codec supported by AOMedia, AV1 provides a long-term, license-free ecosystem for scalable video deployment.
Future-Ready Technology
AV1 supports advanced encoding techniques, improved rate control, 10-bit color depth, and enhanced decoding robustness, making it suitable for AI-driven and next-generation surveillance systems.
AV1 vs H.264 vs H.265
H.264 (AVC)
Widely used due to compatibility and low processing requirements, but limited in handling modern high-resolution video.
H.265 (HEVC)
Improves compression efficiency by approximately 40–50% compared to H.264 and is currently the mainstream codec in IP surveillance systems.
AV1
Further improves compression efficiency beyond H.265, making it suitable for cloud-based, AI-driven, and large-scale surveillance infrastructures.
AV1 in Surveillance Applications
AV1 is particularly suitable for:
Multi-camera deployments with limited bandwidth
Cloud-based video storage and access
AI-powered video analytics pipelines
Long-term video retention with reduced storage cost
Its efficiency enables scalable deployment of high-resolution surveillance systems.
Challenges of AV1 Adoption
Despite its advantages, AV1 adoption in surveillance is still in the early stage due to:
Limited native support in existing cameras and recorders
Higher encoding complexity compared to H.265
Gradual adoption of hardware acceleration
Compatibility requirements with legacy systems
As a result, AV1 is currently more widely used in streaming platforms than in traditional CCTV deployments.
Sunell Perspective
For manufacturers like Sunell, AV1 represents a forward-looking direction in video technology evolution.
It supports the development of more efficient and scalable surveillance systems by enabling:
Reduced bandwidth consumption in multi-channel video systems
Improved cloud integration capabilities
Future-ready camera architecture design
Better alignment with AI-based video processing workflows
While H.265 remains the industry standard today, AV1 provides a clear roadmap toward next-generation intelligent video infrastructure.
Conclusion
AV1 is not an immediate replacement for H.264 or H.265, but it represents a significant advancement in video compression technology.
With strong industry backing, royalty-free licensing, and proven adoption in global streaming platforms, AV1 is positioned to become a key enabler of future cloud-based and AI-driven surveillance systems.
As the industry continues to evolve, AV1 will play an increasingly important role in building scalable and efficient video infrastructure.
