Camera Management: Motion
Setting the motion detection at high sensitivity levels increases
the frequency of false alarms. On the other hand, low sensitivity
levels increase the risk that a significant motion event (such as
an intruder) will not trigger the motion detection to record.
Check the Motion Detection settings both during the day
and at night. In low-light conditions (or when your cameras
are using infrared night vision) the DVR may be more or less
sensitive to motion, depending on your unique circumstances.
The difference might be very dramatic!
The weather conditions are going to affect your motion
detection. Dramatic weather phenomenon such as heavy rain,
strong winds, lightning and so on, may trigger the motion
detection with surprising frequency.
On the other hand, things like fog, mist and other obscuring
kinds of weather might mask or obscure something moving to
the point that the DVR fails to detect them.
•
Limit the motion sensitive area to only the areas
in view that a target could be. In particular, large
featureless areas in the camera's view are the
ones most likely to give false triggers - turning off
the motion sensitivity to any area a target cannot
move in front of will help reduce false triggers - see
"Setting the MOTION DETECTION AREA" on page
49.
Note: The motion detection feature will seem more
sensitive at night. We recommend that you test your motion
detection sensitivity both during the day and at night to
ensure your sensitivity setting is suitable for either lighting
condition.
Some tips to customizing your motion detection
sensitivity and actions:
•
Consider how important it is to be notified of motion
events as they happen.
Using the email alerts is a great way to be kept up-to-speed
on what's happening, but may quickly become annoying
if something occurs which will generate a number of false
triggers. As a rule, we suggest employing the email alert
only on interior cameras during times that no one should be
moving about in front of them.
•
It can be important to have a complete record of a
subject's movements and actions for legal reasons.
If your cameras capture an illegal event (typically an intruder,
but we're continually surprised by stories from our users) it
is important to have as much information as possible. For
example, images of someone in your home may not actually
prove that they broke in - but footage of them breaking a
window does. If you use a camera inside the home to trigger all
exterior cameras with pre-record enabled, then you will have a
record of how they entered in addition to what they did.

Always consider what's really important.
Which is the bigger problem - a dozen false triggers per day, or
missing one critical event?
There's no magic setting which will make motion detection
work perfectly. There will always be some events that it's not
sensitive enough to catch, or minor happenings that will
trigger an overly sensitive camera to record. Typically, the best
motion detection settings are one's that give few false triggers
but don't miss anything.
Even motion detection which false triggers a few times per
hour will still save a significant amount of hard drive space
compared with a constant recording schedule for the same
duration.
You can also use the Privacy Mask option to minimize false
triggers by obscuring different parts of your image - see page
50.
How it Works: Once motion detection has been enabled for
a channel, it will register to the DVR as a Motion Event. Thus,
you can use the Motion recording mode in the schedule to
trigger the DVR to record when motion is detected.
Enable Motion Detection: Whether or not motion
detection is enabled on a specific channel. Each channel
can be configured independently of one another.
Say, for example, you are trying to monitor your front yard,
whilst in the background there is a busy street, and the cars
driving past continually set off the motion detection. What
can you do about it? Setting only part of the camera's view
to be motion sensitive might be the answer. This is useful
in a number of circumstances, such as monitoring one
particular door at the end of a busy hallway, or a backyard
with a tree that keeps blowing in the wind.
Handling: Here you can define what will happen when the
camera you've selected detects motion. You can trigger
additional cameras to start recording; you can adjust your
arming schedule, send alerts to the SwannView Plus client
software and to send an email.
