How to Reduce False Alarms

When we try to keep our family safe by using the camera's alarm system, a false alarm can be annoying coming with lots of alarm emaill, Push notifications and video files. It's also difficult to find the motion events that you really care about from a large number of recording files. However, there are several way to reduce false alarms.

Adjust the motion windows and sensitivity

If the camera is located on a public area where people flow is relatively large, or the camera is set to capture some of the frequent moving objects, such as vehicles, the camera will be triggered by many motion events. That's the common reason for frequent alarm.
To reduce the chance of false alarms you would increase the threshold (move threshold slider to right) or decrease sensitivity (move sensitivity slider to left).

On the other hand, the factory default setting for motion detection is a single motion detection window covering the entire visible area. You may need to decrease the size of the display window towards the left to narrow the surveillance area to reduce the false alarm.

To learn to how to adjust the motion windows please refer to Motion Detection Fine Tuning and Adjustment.

Adjust the Minimum Length of Motion

The “Minimum Length of Motion” feature on Camera Settings page is useful to avoid false alarms. It specifies a minimum length of time for a motion event. If the duration of a motion event is less than the “Minimum Length of Motion”, the alarm won't be triggered. If you set the minimum length of motion as 10, it means the alarm is only triggered when there is continuous motion more than 10 seconds so as to avoid false alarms, for example if an insect flies by, the motion duration is less than 1 second, the alarm won't be triggered.

Set the Alarm interval time

You can also change the "Alarm interval" larger on alarm task configuration page to avoid too many alarm sendings. For example, if you can set the "Alarm Interval" as 600, you will not receive alarm email after a motion detection event happens within 10 minutes. During this alarm interval, any new email alerts will be suppressed.

Use the schedule feature

If you use your email account for motion detection and send a very large number of emails in a short time, the email server may suspect that you are sending spam and may suspend or block your account. Use the schedule feature to send alerts only when you really want them.

Each recording and alarm task under the "Task Management" menu can be set to be active or inactive at certain times of the week, according to the schedule you choose. For more details, please refer to Task and Schedule section.

Use an IR illuminator

At night, if the air is wet or there is a lot of dust, this will cause reflection of infrared LED lights. The reflection of infrared LED lights will trigger the motion detection.

You can turn off the camera's infrared LEDs from the Night Vision Setup page. And this will still allow the camera to see the IR light that is provided by a separate IR illuminator.

To do this, you need to log in to the camera using web browser and go to Setting > camera > Night Vision Setup page. In Night Vision Setup control page, there three options: Auto-On-Off which indicates you should be able to activate-deactivate the Infra-red LEDs independently.
