Instructions

When the system recognizes the existence of QR codes in the current surveillance video, it will take photos and save the file name format as follows: custom prefix _YYYMMDD_HHMMSS_fff.jpg (or. png) and write the QR code into a same name text file.

Do not choose too high camera resolution, the system can automatically obtain the resolution supported by the camera, but the highest resolution may be not necessarily able to support, which is the reason for the camera itself.

After the automatic cleaning is checked, the expired pictures or the early pictures that exceed the capacity under the monitoring picture storage folder will be deleted automatically and permanently. Please be careful not to put the important pictures under this folder in order to avoid data loss!!!. Cleaning out expired files is performed in a multi-threaded way in the background when the software is started. Only when the software is first started can the cleaning process be executed. If the software has not been shut down, the expired files will not be cleared until the software restarts.

Because ID card reader simulates keyboard input, the card-swiping photographic monitoring is also realized by monitoring keyboard input. Therefore, when swiping the card, do not enter the keyboard, so as not to interfere with the card-swiping number reading. In addition, when the main window of the software loses focus, the software will not be able to monitor the keyboard input. Therefore, we should pay attention not to let the software window lose focus. In the Options screen, there is a “Auto Focus ” check box. When the software loses focus, it will automatically restore focus.
