Police video conversion extraction box (vga to usb or dvi to usb)

September 24, 2023

Solve the three major problems of police video evidence collection:

Question 1: How to solve the problem that the embedded monitoring system does not provide any file input and output interfaces? Can I only use a digital camera or camcorder to capture the screen to obtain images and videos?

Solution: The hard disk video conversion extraction processing system can easily solve this kind of problem as long as any image and video can be seen with the eyes. Just connect the display output port (VGA or DVI) of the computer or hard disk recorder, and extract the hard disk recording of all formats in what you see.

Question 2: Most of the hard disk videos can only be played by the manufacturer's own software, and other software cannot be played. How to solve it?

Solution: For hard disk recording. Due to the different encoding and decoders used by various manufacturers, hard disk recordings can only be viewed by the manufacturer's own playback system, and cannot be opened for playback by general media playback software, not to mention the further use of image processing systems for processing. Such problems can be easily solved by simply connecting the hard disk video conversion and extraction processor to the display output port of the host.

Question 3: Whether the device is convenient for carrying and using.

In any case, only one notebook computer is needed to cooperate with the hard disk video conversion and extraction processor. You can extract any format of hard disk surveillance video on site.
