Answer: Set the device’s PIR to high sensitivity to capture the video in 1 second. If a person leaves quickly, within 1 second, the PlR is disturbed, and there may be an alarm that no one appears. Different PIR sensitivities trigger different times, and the following is the description of PIR sensitivity and reaction time.
| Disabled: | Close the PlR function. |
| Low: | The device will start to take videos and send an alert to the mobile device 7 seconds from the moment it detects a moving object. B133 |
| Medium: | The device will start to take videos and send an alert to the mobile device 7 seconds from the moment, it detects a moving object. B133 |
| High: | The device will start to take videos and send analert to the mobile device 1 second from themoment it detects a moving object. |
Note: It is recommended to set the PIR detection disabled” or “Low” to save battery power.
