Note:
1. The recording interval is divided into 0s/5s/15s/30s/60s/3min. During the interval, shooting and recording will not be carried out even if someone moves. The longer the interval is, the longer the standby time of the device will be;
2. The setup is completed just on the APP, and the doorbell needs to be triggered by pressing the doorbell or by someone moving before the doorbell comes online again to take effect.
