Unverified启用硬件编解码时，NVIDIA的NVENC/NVDEC对H.264/H.265/AV1的支持代际很关键，40系支持AV1硬件编码，导出流媒体格式速度显著优于30系及AMD79% similarUnverifiedNVIDIA显卡用户优先用ShadowPlay(GeForce Experience/NVIDIA App内置)，其硬件NVENC编码器录制1080p60占用GPU仅3-5%，远低于OBS软件x264编码77% similarUnverified优先选支持H.265/H.265+编码的NVR，相比H.264可节省50%以上存储空间和带宽。但需确认NVR和摄像头编码格式一致，混用H.264摄像头时无法享受压缩红利74% similarUnverified计划8路及以上或400万像素以上摄像头时，不建议选低端4路窄带宽NVR，会导致解码卡顿、无法同时多画面回放；应关注解码能力（如4路4K解码）与H.265编码支持74% similarUnverified以H.264为例，硬件解码功耗通常仅为软件解码的1/5至1/1073% similar
