Caution
● Normal image level cannot be used under the auto iris mode. Please use the manual iris mode.
● Noise may increase when the number of frames increases, as such, set to an appropriate value.
ⅥSlow Shutter Function
To brighten the images taken in dark places etc.
This function is not achieved through the method of increasing gain electronically. It is accomplished by
accumulating charges stored in the CCD imaging device. In addition, by lengthening the duration for
accumulating charges, more charges could be stored in the CCD and hence allowing high sensitivity
images to be taken under low lighting condition.
The maximum accumulation timing is up till 240 frames (approx. 8 seconds).
ⅥRandom Trigger Function
For verifying the image of a fast moving object detected.
If the trigger signal for the object detected is input, charges will start to accumulate in the CCD imaging
device at the camera. The accumulated charges will be output following the next SYNC signal while
simultaneously, the SI signal will be output as well, hence allowing the images to be stored in the memory.
