Over the past few years, CCTV manufacturers have developed various video encoders from MPEG to H.265. From MPEG to H.264 and now H.265 and H.265+, the main objective of this has been to achieve a higher resolution with smaller file size. With advancements in technologies, these CODECs have changed as well. Read below, about the difference between H.264 and H.265.


What is a CODEC?

CODEC is a COmpressor DECompressor algorithm used to reduce the size of the recorded video.
There are different types of CODECs available for recording video footage of a CCTV.



H.264 was developed in 2003. Also known as Advanced Video Coding (AVC), it is the most used format for video recording, compression and distribution. It has been the most common compression standard for various internet streaming sources and for CCTV Surveillance System.



H.265 or High-Efficiency Video Coding is the new standard of video compression which gives even better performance than H.264. As 4K CCTV Cameras are becoming more popular, more bandwidth and storage capacities will be necessary. This can become difficult to handle for H.264 CODEC, considering the amount of storage HD and 4K video take up.


Why is H.265 the next big thing?

The major difference between H.264 and H.265 is that of streaming bandwidth and storage requirements. H.265 is the best choice if you are using an HD or 4k CCTV Camera. The reason why you should consider using H.265 CODEC is that it can provide considerably higher compression compared to H.264, while still retaining the incredible video quality. This means that the same video quality footage will use less storage space.

A basic comparison of these CODECs can be seen in the graph.

H.265 provides bit reductions of upto 57% at 1080p and 64% at 4K Resolution, which means that you can store more footage, in the same storage space.

The H.265 IP cameras are now everywhere. Since video compression is essential and the H.265 CODEC is the ideal solution for high-resolution IP cameras, it is recommended to choose cameras that offer H.265 standards.
