Door Entry Hikvision Access Control Rs485 Communication?

[Sheraz]

How can I read the card number from a Hikvision access control system (Hikvision DS-K1T341AMF Face Recognition) using RS-485 communication, specifically through a USB-to-RS485 TTL Serial Converter Adapter (such as the FT232 module) connected to a PC or by using an Arduino with an RS-485 TTL MODBUS module? What are the necessary steps, configurations, and protocols (like MODBUS or proprietary Hikvision protocols) needed to successfully retrieve the card number from the access control system via RS-485 and interface it with a PC or Arduino?

The rs485 from hikvision is closed source documentation. I couldnt get hands on even as a distributer and Integration partner.

So you are left with sniffing and decoding the serial data and trying to recreate the way hikvision manage data via 485

Their MODBUS documentation is available for cameras that do have SERIAL output. In other words documentation to integrate PLC

Thank you for your reply. I am using the Hikvision DS-K1T341AMF with the anti-passback feature and a Wiegand connection for the exit card reader. Is there any way to retrieve the card number through serial communication or another method?

Well reader sends data to access control. You can read all events if you create TCP server listener.

Then in access control settings, add your server IP under Alarm server. It will push all the events there in json format. You just parse that data.
