Operation Manual

If you enable adaptive recording on Camera A, only when an event is triggered on Camera A will the server
record the full frame rate streaming data; otherwise, it will only request the I frame data during normal
monitoring, thus effectively save lots of bandwidth and storage space.

Note
• To enable adaptive recording, please make sure you’ve set up the trigger source such as Motion
detection, DI Device, or Manual Trigger.
• When there is no alarm trigger:
– JPEG mode: record 1 frame per second.
– H.264 mode: record the I frame only.
• When the I frame period is greater than 1s on Video settings page, firmware will force decrease the I
frame period to 1s when adaptive recording is enabled.
The alarm trigger includes: motion detection, tampering detection, and DI detection. Please refer to Event
Settings on page 105.
• Pre-event recording and post-event recording: The KX-NTV150/KX-NTV160 has a buffer area (a flash
memory); it temporarily holds data up to a certain limit. Enter a number to decide the duration of recording
before and after a trigger is activated.
• Priority: Select the relative importance of this recording (High, Normal, or Low). Recording with a higher
priority setting will be executed first.
• Source: Select a stream for the recording source.
Note
• To enable recording notification please configure Event settings first. Please refer to page 105.
