The United States of America invented the electronic standard RS-485.
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.
RS-485 is a two wire serial protocol.
The "RS" in RS-232 stands for "Recommended Standard." It was introduced by the Electronic Industries Association (EIA) in the 1960s as a standard for serial communication interfaces, primarily for connecting computers and peripherals. RS-232 defines the electrical characteristics and timing of signals, as well as the physical size and pinout of connectors used in serial communication.
RS232 means "Recommended standard no. 232", EIA standard for serial communication Thirumalesha.....
Yes. Most use wall-wart transformers.

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.
