H.265 IP Cameras vs H.264 IP Cameras
After conducting rigorous testing on H.265 IP cameras and H.264 cameras, we have concluded their main differences from the following aspects:
1. Bandwidth Consumption
H.265 IP cameras possess higher H.265 compression ratios compared with H.264 cameras, reducing network bandwidth consumption by nearly 50% in the same level of video quality. The table below provides an overview of recommended bandwidth for H.265 and H.264 security cameras in different resolutions.

2. Storage Usage
As the bitrate is proportional to the required storage usage, H.265 IP cameras with lower bitrate compress videos in almost half the file size compared to H.264 cameras, while retaining the original video quality.
3. Recording Time Length
H.265 CCTV cameras have lower bitrates than H.264 IP cameras. Thus, with the same storage space, H.265 IP security cameras can allow for longer recording times before the older files are automatically overwritten. (Learn more about how long security cameras can record.)
4. Video Quality
Utilizing the CTUs (Coding Tree Units), H.265 cameras incorporate larger pixel blocks than H.264 IP cameras. These larger blocks improve compression efficiency for larger frame sizes, making H.265 IP cameras more suitable for producing higher resolution images and videos with less bandwidth usage and storage consumption, such as 4K and 8K ultra HD footage.
