This function turns on and off recording moving images.
Set it to off to record audio only (

4-2-1-2. QUALITY (Image Quality)
There are five image quality levels (LL, L, M, H, and HH). If you set this level to “HH”,
then you get more clear images than in other levels, but a larger file size will result. On
the other hand, if you set the level to “LL”, then it requires smaller file sizes, but you get
less clear images compared to the images in “HH”. For example, if you set the level to
“LL”, then the
IV-SGVA
continues to record for 4 days. But, if you set the level to “HH”
for more clear images, then recording time can last about 2 days. This recording time
depends on different recording situations.
4-2-1-3. SENSITIV. (Motion Sensitivity)
This function is to control the sensitivity levels for the motion detection. There are five
sensitivity levels (LL, L, M, H, and HH), and you can decrease or increase this level by
pressing [ ]
◁
or [ ]
▷
. If you set this sensitivity level to “LL” and start to record, then the
sensor detects only the large objects’ movements, and the file size gets smaller. In
contrast, if the sensitivity level is in “HH”, then the sensor can detect even the very
small motions, but the file size gets bigger. The reason for controlling this sensitivity
level is that you may not want to record small motions that are unnecessary to you.
Suppose that you are in an office and placed a
IV-SGVA
to monitor the people
coming in and out of the office, but with the “HH” sensitivity level,
IV-SGVA
records
unnecessary small motions of the people in the office, such as, moving their hands. In
this situation,
IV-SGVA
records too much of data and the file size gets bigger for all
those small motions recorded, and it will take much more time for you to search the
data that you want. In addition, the available memory left for later decreases as the file
size gets bigger, and the battery fades quickly.

Recording frames per second (FPS) depends on the different values for the Image
Resolution.

5. FILE LIM.
This is to turn on and off the function to limit file sizes being recorded. If this
function is turned ON, then a file gets created for every hour or 10MB of file size
while recording images. When you want to start recording by pressing ENT button
and stop from recording by pressing ESC button regardless of the file size, turn
this function to OFF. You are automatically deactivating OVERWIRITE function
when this function is turned OFF.
4-2-1-6. NOISE CUT
In the dark place, there happens many noise of image from the camera. The motion
detection algorithm recognizes that noise as a motion and records the noise even if
there was no actual motion.
IV-SGVA
can cut this noise using the highly-efficient
noise cancellation algorithm. There are five noise cutting levels (LL, L, M, H, HH). If you
set this level to “LL”, then the
IV-SGVA
cuts the low-level noise only. And if you set
this level to “HH”, then the
IV-SGVA
cuts so far as the high-level noise.
Most of the noise can be cut by setting this level to “M”, but sometimes, there could be
high-level noise depending on the kinds of cameras. In that case, you can set this level
to “H” or “HH” to cut the noise.
At dawn, the light becomes bright from dark, generating a lot of noise when the
IV-SGVA
is in such circumstance. And the
IV-SGVA
may recognize those noises as a
motion. In this case, you can set this level to “H” or “HH” to cut the noise.
However, if you set the level to “H” or “HH”, then the motion detection algorithm of the
IV-SGVA
may recognize the actual small motions as noise, and does not record
those small motions. So, set the level to “M” except for the special cases.
4-2-1-7. MOTION DETECT (Motion Detection)
Out of the whole recording area from the camera’s view, this function is used when you
want to detect motions for the specific areas that you have selected only. The whole
recording area is divided into 16 (128x128), 20 (160x128), and 25 (240x240, 320x240,
480x480, and 640x480) blocks depending on the resolution. You can move the cursor
