Motion Detection Events processing

Motion Detection Events processing Anchor Anchor x2

Flussonic Watcher can receive events by email, for this purpose it has a special SMTP server.

It receives emails with motion events from cameras and add corresponding marks in the archive recordings in the places when motion was detected.

You can configure motion detection in two steps:

1) Enable receiving emails in Watcher.

2) –°onfiguring a camera to send emails.

How motion recording works:

Flussonic Watcher maintains a permanent recording with the specified recording depth. When an e-mail arrives with traffic, Flussonic Watcher marks the time interval in the database to reflect the tags in the archive player.

The most important! The record is protected from deletion.

The duration of a protected recording is determined by two timestamps, the first of which is calculated as the current time minus 10 seconds, and the second timestamp is the current time plus 30 seconds.

You just need to set the depth of the archive: for example, 6 hours. Then enable the reception of events.

You will receive 6 hours of continuous archive + sensor entries will be stored as long as there is free space on the disk.

Recording new events will delete the old ones.

Calculating the necessary disk space based on the bit rate of the cameras and the frequency of movements, you can save up to 50-90% of the disk space compared to the normal recording without events.

Enabling event capture in Flussonic Watcher Anchor Anchor x2

Add the lines with the camera_alarm plugin into /etc/flussonic/flussonic.conf:

plugin camera_alarm {
  catch motion;
  listen smtp://0.0.0.0:1025;
}

The catch parameter specifies the word that Flussonic Watcher will search for in the subject of the message. Most cameras send letters with the default subject like this: "Camera 123 Motion Detected at 14:21 27-10-2017".

If your camera sends a letter with a different subject or has the possibilty to specify your own subject, then you configure catch as you like.

The listen parameter specifies the interface and port for the built-in SMTP server. You can set login and password for SMTP:

listen smtp://username:password@0.0.0.0:1025;

Then restart Flussonic Media Server.

The link to the event list will appear on the page of cameras control.

The next step requires that you set email notifications for Flussonic Media Server in the camera interface.

Important! Specify a sender and recipient as a a full camera names (camera name and ID). The full name can be found in the Watcher UI.

Example: cam1-abcdefg@example.com, where cam1 is a cam's name in Watcher and abcdefg is an ID in Watcher.
