Trigger Overview
By connecting an alarm system, motion detector or other type of
sensor to the back of NetCam SC, it is possible to gather a series of
images when the sensor "triggers" the camera.
TRIGGER
I/O Port
Select with I/O port your trigger source is connected to. NetCam SC
only has I/O port 1.
I/O Level
Select the state of the trigger source's output.
SCHEDULE
NetCam SC can wait in trigger-capture/upload mode 24 hours a day,
seven days a week, or you can set whatever time window and days of the
week you like. Use military time for the beginning and ending window
times.
Example: You can configure the camera to only upload Between
07:30 and 18:30 only on Monday, Tuesday, Wednesday, Thursday and
Friday.
PRE-BUFFER
Pre-buffered images are images that are stored before the event
trigger occurs. For example, if you connect an alarm system to the
camera with 10 image pre-buffering enabled, 10 frames of video that
occurred before the alarm was triggered will be captured/uploaded.
If pre-buffering is enabled, the camera will continuously buffer
images in a rotating loop. This will affect the video speed if you'd like to
view live streams at the same time. Most applications don't require pre-
buffering. Only enable this option if you require video frames before the
trigger takes place.
Delay
The number of milliseconds to delay between image captures. For
the fastest possible frame rate, set this to 33. Here are some example
frames rates for a single triggered video source:
33 ms = 30 Frames Per Second (Max Speed)
250 ms = 4 FPS
1000 ms = 1 FPS
Count
The number of pre-buffer images to store. There is a finite amount
