On the client computer, generate an ssh key and upload its public part to the camera.

ssh-keygen -t ed25519 -C "[email protected]"
ssh-copy-id [email protected]

Enter password when prompted to authenticate and upload the key.

Camera logs are stored on temporary storage, which is a RAM disk. This means these logs will be lost after a reboot. If you need to keep logs for a longer period, you can use a syslog server to store them.

Install rsyslog on a Linux machine your network:

sudo apt update
sudo apt install rsyslog

Edit /etc/rsyslog.conf to allow the server to accept remote logs:

# provides UDP syslog reception
module(load="imudp")
input(type="imudp" port="514")

# provides TCP syslog reception
module(load="imtcp")
input(type="imtcp" port="514")

Configure your cameras to send logs to the rsyslog server by adding its IP address to rsyslog_ip parameter of U-Boot environment:

fw_setenv rsyslog_ip 192.168.1.66
