What’s The Difference between H264 VS H265?
Security Cameras and Recording Devices all have one thing in common. They all record or transmit video to each other one way or another and they need a certain kind of technology in order to do so. The technology allowing us to use hard drives or SD cards to record video is called video compression. Common video compression rates used in mainstream video are technologies called H.264 or H.265. The benefits of these technologies allow us to use smaller hard drives/SD cards but still maintain an adequate amount of storage time to go back and review them later.
We are going to dive into both technologies, compare the two, and see if it is really worth the upgrade in cost. H.264 or MPEG-4, is a video compression standard that has been widely adopted by almost every single industry since its inception in 2014. Major video formats like YouTube, Vimeo, and even your Blu-ray discs have adopted this compression rate as the “norm” and it has worked flawlessly, up until now. H.264 still works flawlessly to this day (2018), but with newer technology coming out each and every day, H.264 is bound to be replaced with a newer, and better compression technology. This is where H.265 comes into play.
Most Security Cameras on the market today are utilizing the H.264 compression rate. Major Security brands like Oculur and Axis have adopted the H.264 compression rate across the board implementing the technology into all of their cameras. This allows them to record more video with less storage which saves the customer money and storage space. In the table below, we provide a test scenario showing you how long a camera can record for using the H.264 compression rate. Later on, we will give you the same scenario but using H.265 instead.
H.265 has become known to be the compression of the future. It is very new and hasn’t been implemented into many products yet, but it has been introduced into some of the newer IP cameras on the market. H.265 is a newer compression technology that encodes the video to an even smaller file size. This means you are able to record video and save 50% more video compared to H.264. Encoding technologies like this truly begin to break barriers when it comes to storage management. These technologies can especially be helpful when being used in massive projects that need a extremely large amount of storage. For example, where it is legal, marijuana farms have strict requirements when it comes to the amount of storage they have to keep on file. In some states, they are required to keep up to 6 months of video, recording at 24 hours a day, 7 days a wee. That is an EXTREMELY large amount of storage and is only possible with encoding technologies like H.265. In the table below, we provide the results of a test scenario showing how long the camera can record for using the H.265 compression rate. You can compare these results to the H.264 compression results above and see the difference between the two.
Comparing both of these compression rates, it is clear where the industry is heading, but we don’t want to discourage you from getting anything using H.264. Both of these compression rates do a great Job of saving you money and storage space and we encourage the industry leaders to continue implementing these new technologies. H.265 is clearly the future of security cameras, but one day, we will develop another compression rate that even beats that! This is both the Beauty and the downfall of technology. We know we will get there one day, we just know it is going to take some time and innovation.
Video compression technology tends to see leaps and bounds in advancements. MPEG-2 video encoding standard (H.262) carried us through the 1990s, Advanced Video Coding (AVC, H.264) arrived in the mid-2000s, and now we are seeing High Efficiency Video Coding (HVEC), more commonly known as its codec H.265.
