I. Notes on PCs with Power Save Mode
When the USB camera is used with a PC that has the power save mode, such as a PC with the Intel Core i3, i5, or i7
CPU, the following problem may occur.
An image cannot be obtained with the USB camera
A frame drops frequently
* The issue may occur with other USB camera manufacturers as well.
A. Cause of the Issue
The PC becomes unable to transfer the image because the CPC frequently enters the power save mode during
the image transfer.
B. Solutions for the Issue
This problem can be avoided by disabling the power save mode. However, depending on the PC, the power save
mode cannot be disabled and the desired effect may not be achieved. In addition, when the power save mode is
disabled, undesired effects such as an increase of the power consumption and the heat of the PC may occur.
1. Disable the power save mode by changing the BIOS settings.
Either set “ACPI C State” to “Disable” or decrease the “Max ACPI C State” value step by step until you see the
effect (i.e. C3->C2->C1). (The setting method and the naming may differ, and/or these settings cannot be
changed depending on the PC.)
Please contact the manufacturer of the PC about the BIOS setting.
“ACPI C State” and “Max ACPI C State” may have different names depending on the PC.
Users will be responsible for any change made to the BIOS setting.
The power consumption and the heat of the PC will increase whenever the power save mode is
disabled. Please understand and accept this before disabling the power save mode.
2. Disable the power save mode with the Sentech PC power management software (StPowerCtrl)
Please refer to the Start-Up Guide for the details.
3. Change the camera blanking period and reduce frame rate.
