Alarm recording
Pre-alarm recording
TEC00-014
The alarm recording will be triggered by the alarm inputs or the motion
detection.
Sixteen alarm inputs are assigned one to one corresponding to the 16 cameras.
Once the alarm is triggered either by the alarm input or the motion detection,
the corresponding camera will start recording automatically.
A red indicator indicates that the camera is now under alarm recording.
The alarm recording function of an individual camera can be disabled, also the
alarm recording duration and the frame rate of each camera can be
programmed individually.
Please see the section of "Recorder Setting" for the setup details.
Note:
Only the logon username of "SUPER" can access the utility for
alarm enable and alarm recording parameter settings.
Tip:
In order to verify that alarm recording of particular camera(s) is
actually taking place, the user can try and see if the red indicator
light(s) in the RECORDER PANEL is/are being displayed.
Pre-alarm recording works together with the alarm recording. Pre-alarm
function enables you to capture images before the alarm event is happened.
Pre-alarm allows images to be temporarily recorded for a short period of time
(1 to 60 second) at normal situation. Once an alarm is actually being triggered,
the pre-alarm images become permanent files, which can be retrieved and
played back.
Using "Play Search" function can playback the pre-alarm images.
The pre-alarm function is setup in the "Alarm", "Recorder Setting" inside
"Utility".
You can activate the pre-alarm function accordingly when the alarm function is
selected.
Please see the section of "Recorder Setting" for the setup details.
Note:
Pre-alarm images are stored into two temporary files alternatively
under normal situation. Therefore, when alarm is being triggered,
there will be two pre-alarm files accompanies with the alarm file.
Tip:
Pre-alarm recording provides an effective way of using the hard
disk storage:
The pre-alarm image will be kept in the hard disk only when an
alarm is actually taken place.
Since it provides the image happened before the alarm, you can
review what is happening right before the alarm triggering, it is
no longer necessary to do schedule recording at all time.
For an example, the door was opened, and it triggered the alarm
recording and you can also know who opened the door by playback
the pre-alarm recording video.
