6.1.1. Analog / Digital Gain Settings
ARTCAM-991SWIR-WOM is compatible with analog and digital gain.
Setting value of gain on software can be set from 0 ~ 420, and the gain will change from 0.0dB ~ 42.0dB
accordingly. Gain can be calculated by the following formula:
Gain[dB] = value / 10.0[dB]
Digital gain will activate when setting value of gain > 180.
The graph below shows the relationship between setting value of gain and its magnification[dB].

7. System Requirements
7.1. Recommended System Requirements
●Host Controller
This camera is applicable to USB 2.0.
●CPU The driver of this camera is applicable to computer architecture “x86”or “amd64”.
The specification of CPU effects directly the imaging process speed, therefore it is highly
recommended to utilize a high-end CPU if possible.
●Memory
In the viewer software, there is a data buffer which can store 4 to 8 frames.
Therefore, it is necessary to keep spare space at least for 8 frames in the memory.
(For example, when using 1.3MP color camera, 1280 x 1024 x 3 x 8 [byte] = 30[MB] is
necessary.)
It is highly recommended to keep enough memory space especially when using high resolution
camera.
●OS This camera is applicable only to the architecture of Windows NT (32bit/64bit).
Standard functions are confirmed with OS after Windows 7.
In addition, it is recommended to use Windows 10.
Caution
■Please refer the restrictions below when you use ARTCAM series.
(1) Recommended System Requirements
If the system specifications do not meet the requirements recommended above, it may be difficult to
run at the maximum frame rate.
(2) Connection of Multiple USB Devices
When connecting multiple USB devices to one USB host controller, some USB device may fail to
function stably depending on the specifications of the host controller.
(Problem of power supply, data transfer bandwidth, etc.)
To avoid power supply problem, it is recommended to use powered USB hub.
(3) USB2.0 Cable Extension
We cannot guarantee the functionality of the USB2.0 camera if the user adopts USB2.0 extension
cables or repeaters which are not confirmed by us. With the extension cables or repeaters, the
bandwidth of transfer may differ, and thus caused malfunctions such as a low frame rate or recognition
failure on the camera.
What may cause the problem is that the regulation of the power lines becomes not enough, and so
causes impudence mismatch on data signals.
*For the recommended extension cable, please contact our sales department.
