As a civilian, the acquisition equipment used by individuals can not meet the standard requirements of high definition, and high-definition acquisition equipment is still a relatively expensive product for individuals. At present, the price of general civil acquisition card is 200-400, and the effect is OK. High-definition cards are generally more than 3000, but it still feels expensive if it is not for business needs.
Personal image products are generally collected and carved into DVD, so you can communicate freely. The resolution of 500 lines is enough, and 800 lines of high-definition equipment cannot be realized without corresponding acquisition and output equipment.
