Understanding Storage Efficiency: A Comparison of H.264, H.265, and H.265+

Before engaging the services of a video surveillance company for your business, it's crucial to ensure that the available options include H.264 and H.265 compression storage. Opting for a storage solution lacking H.264 or H.265 technology may result in significant space limitations and additional expenses for storage.

Within the domain of each CCTV system, the focal point revolves around the intriguing aspects of video compression and storage. These technological advancements play a vital role in ensuring the effective acquisition, storage, and transmission of surveillance footage.

What is Video Compression?

Video compression is a process that reduces the size of video files by removing redundant or irrelevant data. Video compression is essential for CCTV systems because it can help save storage space and bandwidth.

  • Storage Space: It refers to the quantity of memory or disk space utilized for storing video files.
  • Bandwidth: It denotes the volume of data that can be sent or received through a network within a specific time frame.

Common video compression standards include H.264, H.265, H.265+, and others.

H.264 Video Compression: What Is It?

The H.264 codec is the world’s most popular compression system and the industry standard. This codec is also known as Advanced Video Coding or AVC. Many video industry creators rely on the H.264 codec because of its general compatibility with lots of devices and IP cameras.

The Advantages of Choosing an H.264 Storage System

  • Versatile and Personalized Solutions: Companies providing H.264 codec storage solutions tailor their offerings to meet the specific needs of your home or business. These customized options provide a clear understanding of the service costs. Moreover, they enable users to save money without sacrificing service quality or speed.
  • Extensive Device Compatibility: H.264 storage seamlessly integrates with a variety of devices, recorders, and streaming equipment. It efficiently operates with even low-end equipment, requiring only minimal quality adjustments.
  • Rapid Compression Speed and Swift Video Delivery: Video surveillance providers prefer H.264 technology for its speedy compression rate. The compression speed is further enhanced with high-end or moderately capable equipment, allowing efficient handling of large batches of video files within a reasonable timeframe.

H.265 Video Compression: What Is It?

H.265, also known as High-Efficiency Video Coding (HEVC), is a video codec that was released in 2013. It is the successor to H.264 and was designed to provide better video compression while maintaining the same level of video quality. H.265 can achieve up to 50% more compression than H.264.

The Advantages of Choosing an H.265 Storage System

  • Better Storage Savings: For efficient storage of high-quality videos without excessive space usage, choosing a dedicated H.265 storage option is superior to H.264. This HEVC storage solution allows simultaneous saving and compression of multiple videos.
  • Minimal Video Quality Degradation: HEVC technology employs an advanced 'lossy' compression method, unlike H.264's lossless standard. Despite H.265 adjusting frame quality during compression, the loss is minimal.
  • Adaptive 4K Resolution Compatibility: H.265 compression technology supports 4K resolution files, allowing seamless viewing and editing without software restrictions. Certain H.265 storage systems can even handle 8K UHD resolutions.

H.265+ Video Compression: What Is It?

H.265+ encoding technology, developed by HikVision, enhances HEVC capabilities and reduces the overall bitrate of the H.265 codec. Through H.265+, end-users gain high-quality compression, increased storage efficiency, and accurate video analysis.

The Advantages of Choosing an H.265+ Storage System

  • Extensive Storage and Bandwidth Efficiency: H.265+ technology enables a remarkable 60% reduction in file size. If the video cycle doesn't span 24 hours, the file size can be substantially smaller. Over time, H.265+ ensures impressive storage savings, surpassing those offered by H.265 providers.
  • Enhanced Outcomes from Motion Sensing Devices: HD surveillance cameras and DVRs demand sophisticated hardware. Effective, high-quality H.265+ storage enhances analytics, leading to better interpretation and documentation of recorded footage.
  • Upgradable Features: Most of the features offered by an H.265+ provider are adaptive and upgradeable. H.265+ storage is compatible with a wide range of devices and also offers cloud support.

Technical Comparison Between H.264, H.265, and H.265+

Understanding the technical comparison points between the most popular video compression systems is a great way to maximize your purchase.

  • H.264/AVC: 45%, Up to 4K, 160 TB
  • H.265: 60%, Up to 8K, 250 TB
  • H.265+: 80%, Up to 8K, 250 TB

Choosing the right system depends on resolution, bandwidth, and storage needs, ensuring an informed decision tailored to specific priorities.

Conclusion:

Whether you’re planning to opt for H.264 or H.265 storage options, it's crucial to consider your long-term priorities. H.265 compression technology can lead to cost savings over the next three to five years, but it requires high-end (or midrange) equipment and a substantial financial investment.

In contrast, H.264 technology has a lower barrier of entry, but it demands higher storage due to lossless compression.
