Status > Firmware Version: v403r11.Before downloading firmware, understand why v403r11 explicitly mentions both codecs: v403r11 h264 h265 dvr nvr firmware download hot work
| Feature | H.264 (AVC) | H.265 (HEVC) | |---------|-------------|---------------| | Bandwidth | High | ~50% lower than H.264 | | Storage | Requires more HDD space | Saves up to 40% storage | | Compatibility | Universal (all old cameras) | Requires newer IP cameras | | Processing power | Low | High (needs modern chipset) | Even with a clean download, issues can arise
The v403r11 firmware optimizes the transcoding process between these two codecs, allowing your DVR/NVR to record in H.265 (saving space) while streaming remotely in H.264 (for older browsers or mobile devices). After 3–5 minutes, the recorder will automatically restart
