Alarms Overview
Menu Location: Settings - Alarms
Alarms can only be used while in Monitor Mode. Not for Record Mode or Stream Mode. Alarms can be set on a per camera basis, as well as being able to define a Motion Detection Region in the image.
The program has the following alarms.
Are based on the number video frames that have motion detected in them, or no motion detected in them, for a given time period. The given time period is called the Alarm Polling Time, and the number of video frames is called Frames for Alarm.
An Alarm Condition on a camera occurs when there the number of frames with motion detection in them is greater than the Frames for Alarm parameter. Or if No Motion Detection is used, an Alarm Condition on a camera occurs when there the number of frames with motion detection in them is less than the Frames for Alarm parameter. A camera with an Alarm Condition on it will trigger a Sound or Email Alarm. If more than one camera has an alarm condition on it at the same time, then only one sound or email alarm will be generated.
A Frame is a video frame or a single video image, or a single video picture. Moving video consists single video pictures played quickly back to back, for example at a rate of 30 frames per second.
To set an email or sound alarm for an individual camera, the following must be set:
The sound alarm can have one sound, a separate sound alarm for each camera. The one email alarm lists all the cameras which had an alarm on them.
Issues a sound whenever motion is detected on a particular camera. It is not the same as a Sound Alarm which uses many motion detections to generate a sound alarm. The sound can be a beep, or a separate sound for each camera.
To set Detection Sound, put a check mark beside Use Detection Sound.
Sets an alarm condition if no motion is detected. That is if the number of frames with motion detected in them is below the Frames for Alarm value. For an alarm to be issued a check mark must also be beside Use Email or Sound Alarm as above, as well as Use No Motion Detection.
