4-2-1-1. VIDEO

This function turns on and off recording moving images.

Set it to off to record audio only (SG-200, SG-210, SG-300, SG-310 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 Self-Guard 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 Self-Guard to monitor the people

coming in and out of the office, but with the “HH” sensitivity level, Self-Guard records

unnecessary small motions of the people in the office, such as, moving their hands. In

this situation, Self-Guard records too much of data and the file size gets bigger for all
