Remote Printing Infrastructure

Raspberry Pi 3 B+ (`seth-pi`)

Hostname: seth-pi
OS: Debian 13 (Raspberry Pi OS Lite)
User: seth (key-only SSH, no root login)
wlan0: 192.168.0.102 (main network, DHCP) — default route
eth0: 192.168.0.101/24 (isolated camera router subnet)
WiFi SSID: WiFrei

OctoPrint

URL: http://octopi.sethpc.xyz (port 5000 on Pi)
API key: see octopi.sethpc.xzy_api_key.md

go2rtc (v1.9.14)

Restreams both cameras with H.264 hardware transcoding and MJPEG fallback.

API: http://192.168.0.102:1984
RTSP: rtsp://192.168.0.102:8554
Streams:
- cam1 / cam1_mjpeg — Camera 1 (192.168.0.100)
- cam2 / cam2_mjpeg — Camera 2 (192.168.0.103)

IP Cameras — TENVIS (on isolated eth0 subnet)

Both TENVIS cameras use credentials admin:admin and expose RTSP on port 554 (/11 path), HTTP on 80, and ONVIF on 8080.

Internal model: C9F0SeZ0N0P4L0 (Hi3510-based SoC)
Firmware: V9.1.6.1.24-20170925
Hardware version: V1.0.0.1
CGI interface: /cgi-bin/hi3510/param.cgi
cam2 has an SD card inserted (59GB)

Camera	Isolated IP	Proxy Ports (on .102)
cam1	192.168.0.100	HTTP:18080, ONVIF:18081, RTSP:18554
cam2	192.168.0.103	HTTP:28080, ONVIF:28081, RTSP:28554

Proxy Architecture

The Pi bridges two networks:

eth0 (192.168.0.101) connects to an isolated router with the two IP cameras
wlan0 (192.168.0.102) connects to the main homelab network
socat systemd services proxy each camera port from the isolated subnet to the main network
Port scheme: 1xxxx = cam1, 2xxxx = cam2

Proxy services (all systemd, auto-restart):

ipcam-proxy-http.service — 18080 -> 192.168.0.100:80
ipcam-proxy-onvif.service — 18081 -> 192.168.0.100:8080
ipcam-proxy-rtsp.service — 18554 -> 192.168.0.100:554
ipcam2-proxy-http.service — 28080 -> 192.168.0.103:80
ipcam2-proxy-onvif.service — 28081 -> 192.168.0.103:8080
ipcam2-proxy-rtsp.service — 28554 -> 192.168.0.103:554

Camera Control Panel

URL: http://192.168.0.220:8090
Location: /opt/cam-control/server.py on CT 241 (Frigate)
Service: cam-control.service (systemd, enabled)
Features: Live MJPEG feeds, PTZ D-pad (continuous/step), speed control, flip/mirror toggles
Source: ./cam-control/server.py

Gitea

Repo: https://git.sethpc.xyz/Seth/3d-printing
Remote: https://Seth:REDACTED_GITEA_TOKEN@git.sethpc.xyz/Seth/3d-printing.git

Conventions

Camera credentials: admin/admin (default, isolated network only)
Pi SSH: key-only as seth, no password auth
Internal password for homelab services: REDACTED_PASSWORD
