There are three parking modes, and buffered parking mode will only work under the auto event detection parking mode.
Turn on auto event detection, the buffered function will work automatically.
Buffered Parking Mode means the camera can lock a longer length of the video, 15s/5s before the event is triggered, so a total of 45s/30s video will be locked.
There is some difference between different models.
|Model||15s buffer||5s buffer||Length of each video clip||Video Path|
A119 V3、A119 Mini、A129 DUO、A129 PRO、
A139、A139 PRO、A229 DUO
|√||45s||Locked in RO folder|
Tips: A129 PLUS、A129 PLUS IR do not support buffered parking mode.
