The UART Camera support RS232/RS485/TTL Serial port. Which UART port is depended by the host device. The host can only communicate with 1camera through RS232 and TTL port via only 1 cable. For 485 port, you can connect several cameras in series and your host can communicate with them with same cable via ID No. All of our camera has the default ID. “0” if you use QQZM’s Standard ZMID protocol.

The baud rate can range from 9600bps to 115200bps. Which baud rate is also decided by your host device. The default is 115200bps.
