With the rapid evolution of video surveillance systems—from HD IP cameras to 4K/8K smart surveillance and AI-powered video analytics—the demand for efficient video compression has never been higher. Bandwidth limitations, storage costs, and remote access performance are now critical factors in system design.
AV1, developed by the Alliance for Open Media (AOMedia), introduces a next-generation, royalty-free video codec designed to significantly improve compression efficiency while reducing overall system cost and bandwidth consumption.
What is AV1?
AV1 (AOMedia Video 1) is an open and royalty-free video codec finalized in 2018. It is supported by a broad industry alliance including Amazon, Apple, Google, Meta, Microsoft, Mozilla, Netflix, NVIDIA, and Tencent.
Unlike traditional codecs such as H.264 (AVC) and H.265 (HEVC), AV1 is designed for modern high-resolution video applications and large-scale streaming systems, including video surveillance platforms, cloud VMS, and remote monitoring systems.
Compared to H.264 and H.265, AV1 provides:
Up to 50% bitrate reduction compared to H.264
Around 20–30% better compression efficiency compared to H.265
This makes AV1 highly suitable for multi-camera surveillance deployments, cloud recording systems, and bandwidth-constrained environments.
Key Advantages of AV1 in Video Surveillance

AV1 vs H.264 / H.265 in Surveillance Systems
While H.264 remains widely used due to its compatibility, it requires higher bitrates to maintain image quality.
H.265 improves compression efficiency but still relies on complex licensing structures and does not fully optimize low-bandwidth environments.
AV1 addresses these limitations:
Higher Compression Efficiency → More cameras per network & longer storage retention
Lower Bandwidth Usage → Smoother remote monitoring and multi-channel streaming
Reduced Total Cost of Ownership → Lower storage, transmission, and infrastructure costs
Improved Performance in Weak Networks → Better stability for remote surveillance access
