We will introduce the advantages and disadvantages of web cameras and industrial cameras.
As a representative of inexpensive cameras, there are webcams that can be connected to a computer via USB. Their prices start from around 1,000 yen, making them quite affordable, but it's good to understand the reasons why industrial cameras are generally used for image processing to avoid potential issues. Of course, the cheaper option increases cost-effectiveness, but in my experience, there are "3" customers using webcams compared to "7" customers using industrial cameras. Conversely, this means that 30% of customers can operate effectively with a webcam.

basic information
■Web Camera Advantages - Inexpensive (around 1,000 yen) Disadvantages - The sensor size is small (about 3mm square), resulting in noisy images. - Generally, the lens cannot be changed, so the field of view cannot be selected. - Many models cannot store settings like exposure time, and most have automatic exposure, which can lead to fluctuating exposure times and unstable results. - Not suitable for inspections that require precise timing, such as inspecting moving items or items with a short stationary time. - Since it continuously captures images as video using the DirectShow standard, the USB data transfer volume is high → Generally, only 2 to 3 cameras can be connected to a single PC.

■Industrial Camera Disadvantages - Not inexpensive (approximately 30,000 to 100,000 yen) Advantages - The sensor size is about 5mm to 10mm, providing a large light-receiving area and low noise. - The angle of view can be selected by changing the lens, and the large lens results in low distortion and high resolution. - Settings such as exposure time can be finely adjusted, and many settings can be saved. - Synchronization in microseconds (µs) is also possible. - Since the primary method is to capture a single image when needed, it operates stably even when connecting more cameras (3 to 4) compared to DirectShow. *For more details, please refer to the related links or feel free to contact us.*

Company information
"Achieve significant effects" while "keeping costs down." It requires endless effort despite its simplicity. This is why SkyLogic believes it is valuable to continue pursuing "cost-effectiveness" through means such as technology and services. EasyInspector2/DeepSky: An appearance inspection software with a cumulative installation record of 2,500. Effect: We have developed a high-precision and lightweight AI model. It can connect five cameras simultaneously to one PC. Cost: To reduce the cost of learning setup, it is no-code, and simply deciding the inspection mode determines the necessary processing. Expansion and horizontal deployment are possible at low cost. EasyMonitoring2: A system that accurately reads and records meters through cameras and notifies of abnormalities, eliminating time-consuming and costly patrol monitoring. Effect: Not only meter reading but also the confirmation of processing tanks and oil leaks can be automated using AI. Cost: It can connect to inexpensive cameras, up to 100, with one PC. There are no monthly fees. In addition to these, we offer various products for "cost-effectiveness." Please let us know your company's challenges and themes.
