Camera Tampering
Camera Tampering can generate an alarm whenever the camera is repositioned, or when the lens is covered, sprayed or severely
defocused. To send an alarm, for example an email, an action rule must be set up.
To configure tampering:
1. Go to
Detectors > Camera Tampering
.
2. Set the
Minimum duration
, that is, the time that must elapse before an alarm is generated. This can help prevent
false alarms for known conditions that affect the image.
3. Select
Alarm for dark images
if an alarm should be generated if lights are dimmed or turned off, or if the lens is sprayed,
covered, or rendered severely out of focus.
4. Click
Save
.
To configure the product to send an alarm when tampering occurs:
1. Go to
Events > Action Rules
.
2. Click
Add
to set up a new action rule.
3. Enter a
Name
for the action rule.
4. Under
Condition
, select
Detectors
from the
Trigger
list.
5. Select
Tampering
from the list of detectors.
6. Select the video channel.
7. Optionally, select a schedule and set additional conditions.
8. Select the action. To send an email, select
Send Notification
and select a
Recipient
from the list of defined recipients.
Note
The
While the rule is active
option under
Duration
cannot be used with camera tampering, since camera tampering does not
have a duration and once it has been triggered it will not automatically return to its untriggered state.
For more information on actions rules, see
Events, on page 36
.
Motion Detection
Motion detection is used to generate an alarm whenever movement starts or stops in the camera view.
Motion detection is configured by defining up to 10 Include and Exclude windows:
•
Include windows
— define areas where motion should be detected
•
Exclude windows
— define areas within an Include window that should be ignored (areas outside Include windows
are automatically ignored).
For instructions, see
Set Up Motion Detection Windows, on page 32
.
To control the number of motion detection alarms, the parameters
Object Size
,
History
and
Sensitivity
can be adjusted. See
Motion Detection Parameters, on page 32
.
Once motion detection windows are configured, the Axis product can be configured to perform actions when motion is detected.
Possible actions include uploading images and start recording. For more information, see
Setting Up an Action Rule, on page 37
