peel out RS485 communication cable, then connect back of the DVR panel. in RS 485 control system then ... go to protocol setting in the DVR on that assign camera ID.. then save.. finish.
The United States of America invented the electronic standard RS-485.
RS-485 is a two wire serial protocol.
RS232 means "Recommended standard no. 232", EIA standard for serial communication Thirumalesha.....
Yes. Most use wall-wart transformers.
Recommended Standard 232
RS-422 is a standard for serial data communication that allows for long-distance transmission of data at high speeds. It uses differential signaling, which enhances noise immunity and allows for communication over distances up to 4,000 feet (1,200 meters) at data rates of up to 10 Mbps. RS-422 can support multiple receivers on the same line but is primarily designed for point-to-point communication. This standard is commonly used in industrial automation, telecommunications, and computer networking applications.
Its not, it just happens to be convenient. Other standards for UART communication include RS-422, RS-423, RS-481, and various others.

The RS-422 EIA-449 interface standard provides a faster data transer rate than the RS-423 EIA-449 interace standard.
