Over the past 10 years, surveillance manufacturers developed various encoders from MJPEG to H.265. The main objective is to achive higher resolution with lower bandwidth. While other companies are still struggling for upgrade to H.265, Hikvision has once again proven their ability to excel in the surveillance industy by raising the bar with their new H.265+ encoder.
What is the difference between H.265 and H.265+?
H.265 and H.265+ are both video compression standards, but H.265+ is an improved version that offers some additional features.
H.265+ is an optimized version of H.265, with specific improvements tailored for certain applications, particularly in the field of surveillance and security. If you’re working with video content in a surveillance context, H.265+ may be a more suitable choice due to its enhanced compression capabilities. However, it’s important to note that support for these standards may vary across devices and software, so compatibility should be considered when choosing between them. Here’s a brief overview of both:
H.265 (HEVC - High-Efficiency Video Coding)
- Developed as the successor to H.264 (AVC), H.265 aims to provide better compression efficiency while maintaining high video quality.
- It reduces the file size of video content, making it more efficient for streaming and storage.
- H.265 achieves higher compression ratios compared to H.264, resulting in smaller file sizes for the same level of video quality.
H.265+
- H.265+ is an extension or enhancement of the H.265 standard, designed to further improve compression efficiency and address certain limitations.
- One key feature of H.265+ is its ability to reduce the bitrate further by optimizing the encoding process, especially for surveillance video applications.
- It is particularly popular in the security and surveillance industry, where efficient video compression is crucial for storing and transmitting large amounts of surveillance footage.
- H.265+ achieves better compression ratios than H.265, meaning that it can reduce file sizes even more without sacrificing video quality.
H.264 vs H.265 vs H.265+
The information provided here is a general overview, and the performance of each codec can vary depending on specific implementations, configurations, and use cases.
