Disable AI mode NVR404L-32-I & NVR402A-16/16P-I
The NVR404L-32-I and NVR402A-16/16P-I can do 200mbps under normal circumstances. When "AI Mode" is enabled, the bandwidth capability is 80 mbps.
AI Mode in this example means that the recorder has an entry set to "By Recorder" rather than by the IP camera.
To disable this you must go into AI->Parameters. Any entries that are set to enable with "AI By recorder" means that AI Mode is ON.
You may check the bandwidth from the LOCAL GUI. Main menu -> Camera -> camera list -> bottom of the screen. (NVR4-I not used in example below.)
