How Motion Detection Works
The way that the NVR looks for motion is quite straight forward - it’s a process where it compares one frame
with the next. A certain amount of “difference” between these two “frames” is interpreted as motion.
As a result, the NVR is able to detect when there is a change in the picture. However, this does not
necessarily need to be something moving in the frame. For example, a light being turned on or off, a lightning flash or
even the sun coming out momentarily on a cloudy day might be enough to trigger the motion detection on the NVR.
However, as these events last only a moment (and are relatively rare) they will only create a few very short redundant
clips, which will not take up too much space or pose a problem with scanning through footage.
For this reason,
don’t use PTZ systems and motion detection simultaneously
. The NVR will interpret the camera
moving as ‘motion’ and record. This is particularly true when using Cruise Mode - as the camera is moving almost
continually, so too is the NVR recording almost continually!
Here, you’ll be able to set the motion detection features of the NVR for each channel. We suggest that motion detection
is, under most circumstances, the most practical recording method for the NVR to employ.
How it Works:
Once motion detection has been enabled for a channel, it will register to the NVR as a
Motion Event
.
Thus, you can use the Motion recording mode in the schedule to trigger the NVR to record when motion detection
triggers an alarm signal.
Enable:
Whether or not motion detection is enabled on a specific channel. Each channel can be configured
independently of one another.
Sensitivity:
If the motion detection sensitivity is
too sensitive
, then the NVR will record too frequently or continually -
any benefit of motion detection will be lost. If the motion detection sensitivity is not sensitive enough, then the NVR will
not record when it should and may not record anything at all.
Here you can setting sensitivity on different time , for example , night time sensitivity is higher and day time sensitivity is
lower for frequent movement on the daytime .
Schedule:
you can set the motion detection schedule time here , one box means 1 hour.
Action:
Here you can define what will happen when the camera you’ve selected detects motion.You can enable Audio
Warning , and send e-mail when motion happen .
Note: If you’ve used the Copy-To feature to copy from one camera to another, remember that you’ll still need to set the
Action
for each channel independently - that information isn’t copied.
Full Screen:
Setting the motion detection area , you can drag the box to un-choose the area. For example , you can
using the grid to cover your front door , so your front door will be set as the motion detection area ,
Clear Area
: Clear Area means no area for motion detection .
