The status quo of embedded DVR

The status of embedded DVR: few companies with independent research and development capabilities
1. Technical threshold: DSP development, embedded real-time operating system development, network development
Generally, there is no low-level development capability, and the use of foreign programs is limited by the original plan, resulting in insufficient flexibility to meet the diversified needs of customers;
2. Funding threshold: the establishment of the development environment, the establishment of the development team, the investment of development funds, and the shortage of development talents.
Some have no network functions, some have network functions but are not strong.
