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
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.
Industries using a 4G-LTE RS-485 Modbus Gateway gain multiple advantages, including: Remote Monitoring: Real-time insights without needing on-site presence. Data Collection: Integrated analog and digital I/Os capture diverse data types for comprehensive analysis. Enhanced Efficiency: Streamlined data communication improves control over processes. Cost-Effectiveness: Reduces need for extensive wiring and manual monitoring. Improved Decision-Making: Real-time data aids quick, informed decisions, enhancing productivity.
