“How can I choose the right scanner for myself?”
This should be a puzzle for many of us who use scanners for the first time.
It is the most direct method to tell the product customer service our barcode scanning requirements and ask them to recommend the corresponding products according to our requirements.
But what should we do if we want to pick the right model by ourselves？
Find the parameter table of the product, compare these parameters, and consider the price factor comprehensively. We will get the one product that suits us best in our hearts.
But before that, can we really understand the parameter table? What does each of their parameters represent?
A sensor is a device that measures physical input from its environment and converts it into data.There are three types of sensors for barcode scanners: laser, ccd, and cmos. We can choose the sensor according to the type of decoding we need.
Optical resolution refers to the actual amount of information that the optical system of the scanner can collect, that is, the resolution of the photosensitive element of the scanner. Generally expressed in DPI. Common optical resolutions are 300×600dpi, 600×1200dpi, 1200×2400dpi or higher. In general, the larger the DPI value, the better the scanning effect.
Color resolution is also called color depth, color mode, color bit or color scale. These are indicators that indicate the fineness of the color or grayscale of the scanner, and its unit is bit (bit). Theoretically, the more color bits there are, the more realistic the colors will be.
All kinds of scanning guns indicate its optical resolution and color resolution.
Depth of Field
Depth of field refers to how far a barcode scanner can read from a barcode. In general, the farther a barcode scanner can read a barcode, the better the scanner’s scan engine will be, but it will also cost more.
After simply comparing these parameters, you will choose which barcode scanner is most suitable for you.
