TailCam

Every webcam you own. One private dashboard. Anywhere.

TailCam turns any Linux, macOS, or Windows machine with a webcam into a private, AI-powered camera system you can watch from anywhere over Tailscale — no TailCam cloud, account, or subscription, and no port forwarding.

Why TailCam?

Old webcams are everywhere — in drawers, on shelves, attached to machines that are already running. TailCam puts them to work as a monitoring system that is genuinely yours:

• Private by construction — the server binds to 127.0.0.1 and is only reachable over your tailnet. Tailscale's encryption and identity are the security boundary; there is nothing to expose to the internet and no vendor in the loop.
• A real product, not a science project — a polished installable PWA dashboard, desktop tray apps for all three OSes, an optional browser extension, motion detection with recording, object detection out of the box, timelapses, a plugin marketplace, and an MCP server for AI agents.
• Fleet-native — install it on two, three, ten machines; every node discovers the others and shows all cameras in one dashboard, from any device.
• Local AI, zero setup — live bounding boxes and labeled motion events from a built-in detector that downloads itself on first use and runs entirely on your hardware. Scale up to Ollama vision models, or train your own — still local.

A quick tour

Video wall — every camera full-bleed on one screen (press W). Low-bandwidth tiles; click any feed for full quality.	Camera view — live stream with per-viewer FPS/zoom/pan/quality, plus device-wide resolution, rotation, and flips. Snapshot and record in one tap.
Events — the motion log across all devices, with per-event clips, thumbnails, and AI labels when enabled.	Gallery — snapshots and recordings from every camera, filterable by device and type.
AI Studio — object detection, Ollama motion analysis, training, and active learning — all local, managed from one place.	Timelapse — long captures with printer presets, then “Smooth” them into flowing motion with ffmpeg or GPU RIFE interpolation.
Plugins — one-click, checksum-verified community plugins: notification channels, AI providers, event automations.	MCP — connect Claude Code, Codex, or any MCP agent to your cameras with copy-paste snippets. 47 tools, role-gated and audited, over a stateless endpoint.
Settings — system console: fleet devices, Tailscale status, storage and retention, integrations.	Docs — the full manual ships inside the app. Everything you need without leaving the dashboard.

Install in 60 seconds

TailCam is available on PyPI. For the published release, use pipx or pip with Python 3.10+:

pipx install tailcam
tailcam run

Open http://localhost:8088/. The package includes the built dashboard; Node.js and a Git checkout are not needed. See pipx setup if the pipx command isn't installed.

For automatic system dependencies, Tailscale setup, and a background service, use the OS installer below. These installers fetch GitHub main by default, which can be newer than the published PyPI release.

Linux (Debian/Ubuntu/Raspberry Pi OS):

curl -fsSL https://raw.githubusercontent.com/factshin/tailcam/main/install-linux.sh | bash

macOS:

curl -fsSL https://raw.githubusercontent.com/factshin/tailcam/main/install-macos.sh | bash

Windows (PowerShell):

irm https://raw.githubusercontent.com/factshin/tailcam/main/install.ps1 | iex

Each installer:

• checks for Python 3.10+ (Linux also installs the system libraries numpy/OpenCV need),
• installs TailCam into an isolated virtualenv,
• registers a background user service so TailCam starts automatically — systemd --user + lingering (Linux), launchd agent (macOS), or a logon Scheduled Task (Windows),
• detects Tailscale and, if it's running, exposes the UI over HTTPS with tailscale serve.

After install, open the URL printed at the end (your tailnet HTTPS address, or http://localhost:8088/ locally).

# Linux / macOS — download then run with flags:
curl -fsSL https://raw.githubusercontent.com/factshin/tailcam/main/install-linux.sh -o install-linux.sh
bash install-linux.sh --port 9000 --no-tailscale

# Windows:
irm https://raw.githubusercontent.com/factshin/tailcam/main/install.ps1 -OutFile install.ps1
.\install.ps1 -Port 9000 -NoTailscale

Install from PyPI

pipx keeps TailCam in its own environment and exposes the tailcam command:

pipx install tailcam
tailcam run

For a fresh install with HomeKit, use pipx install 'tailcam[homekit]' instead. To add HomeKit to an existing pipx install, use pipx inject tailcam 'tailcam[homekit]' and restart TailCam.

pip in a virtual environment — Linux/macOS:

python3 -m venv .venv
.venv/bin/python -m pip install tailcam
.venv/bin/tailcam run

Windows PowerShell (use x64 Python on Windows ARM):

py -3 -m venv .venv
.\.venv\Scripts\python.exe -m pip install tailcam
.\.venv\Scripts\tailcam.exe run

Install extras using the same environment as the running server, for example .venv/bin/python -m pip install 'tailcam[homekit,mqtt]' on Linux/macOS or .\.venv\Scripts\python.exe -m pip install 'tailcam[homekit,mqtt]' on Windows. HomeKit live video also needs system ffmpeg. Manual PyPI installs do not install Tailscale or register a background service; see the installation guide for those steps and the environment paths used by the OS installers.

Updating

• PyPI / pipx: pipx upgrade tailcam.
• PyPI / venv: .venv/bin/python -m pip install --upgrade tailcam (Windows: .\.venv\Scripts\python.exe -m pip install --upgrade tailcam). Include your extras, such as 'tailcam[homekit,mqtt]', when upgrading their dependencies too.
• GitHub installer / development channel: tailcam update checks and installs GitHub main; tailcam update --check only checks. The dashboard and desktop update actions use this same channel, even for a PyPI install.

Restart the running server after a package upgrade (tailcam restart for a registered service), then check tailcam version. To stay on published PyPI releases, use pip/pipx upgrades rather than the in-app updater. Source installs remain available with python -m pip install git+https://github.com/factshin/tailcam.git in an activated virtual environment.

Docker

Run TailCam fully isolated in a container. The image bundles TailCam, the dashboard, Tailscale, and the OpenCV/ffmpeg libraries.

One-liner (Linux host with Docker) — pulls the prebuilt image and runs it:

# local-only (open http://localhost:8088/)
curl -fsSL https://raw.githubusercontent.com/factshin/tailcam/main/install-docker.sh | bash

# join your tailnet and serve over Tailscale
curl -fsSL https://raw.githubusercontent.com/factshin/tailcam/main/install-docker.sh | bash -s -- --authkey tskey-auth-xxxx

Prebuilt image (multi-arch — amd64 + arm64/Raspberry Pi):

docker pull ghcr.io/factshin/tailcam:latest

Docker Compose (from a repo checkout):

# local-only — reach it on the host at http://localhost:8088/
docker compose up -d

# or join your tailnet and serve over Tailscale
TS_AUTHKEY=tskey-auth-xxxx docker compose up -d

With TS_AUTHKEY set, the container starts tailscaled, joins your tailnet as tailcam, and serves at https://tailcam.<tailnet>.ts.net:8443/ — the same experience as a native install, plus full verified-admin access. Without it, TailCam runs local-only on the published port.

Pass a webcam with --device /dev/video0:/dev/video0 (Linux hosts only — Docker Desktop on macOS/Windows can't see host USB cameras; use a native install there, or TAILCAM_SYNTHETIC=1 to test). Data, config, and Tailscale identity persist in named volumes. Build directly with docker build -t tailcam ..

Full details — networking modes, persistence, env vars, and troubleshooting — are in the in-app Docs → Running in Docker page (also served at /docs/docker).

Feature highlights

• Polished dashboard (PWA) — a responsive React web app (installable on phone or desktop) with a live camera grid grouped by device, a video wall, a command palette (Cmd/Ctrl+K), a mobile-first camera view with pinch/zoom, gallery, and motion events. Built and shipped inside the package; see web-ui/.
• Desktop app (macOS, Linux, Windows) — a menu-bar/tray app with the dashboard in its own window, service controls, fleet-node switching, and one-click updates (tailcam app) on all three platforms.
• Browser extension (optional) — TailCam Companion for Chrome, Edge, Firefox, and Safari; see below.
• Multi-host aggregation — see every camera, recording, event, and timelapse across all your tailnet devices from any one of them.
• Storage node & detection node — record, timelapse, and run object detection for a small node's cameras on a bigger machine on your tailnet (the box with the disk, the box with the GPU); the Pi just captures and streams.
• Multi-camera — auto-detects connected webcams; name them and view them in a grid.
• Resolution, zoom & pan — set capture resolution; pinch/zoom + pan; rotate/flip; brightness/contrast controls; device-wide stream settings (fps, quality, size) that are the same on every screen.
• Snapshots & recording — capture stills and record browser-playable H.264 clips to disk (or a NAS folder picked with the built-in folder browser), with a gallery.
• Motion detection — detect motion, log events, and save a clip per event (on by default); remembered across restarts.
• Object detection — built-in live bounding boxes + labels (80 COCO classes), zero setup, auto-downloading local model; per-camera on/off; upgrades itself to Ultralytics YOLO11 when torch is installed.
• Timelapse + smoothing — capture a timelapse (great for 3D prints) on any node, then "Smooth" it into flowing motion with a bundled ffmpeg engine or an optional GPU RIFE model (rife-ncnn-vulkan), with automatic fallback.
• Raspberry Pi friendly — a low-power profile (lighter streams, MJPEG capture, shared JPEG encoding, ultrafast x264) keeps a 1 GB Pi 5 streaming two cameras.
• Train your own model — collect and label footage from your own cameras and fine-tune a private model on your Mac/Windows GPU (optional tailcam[training] extra) — classification or object detection, with in-dashboard box drawing.
• Active learning (human-in-the-loop) — auto-label confident detections, send only uncertain frames to Label Studio, and fine-tune YOLO, Florence-2, or Qwen2.5-VL from the synced annotations.
• Plugin marketplace — one-click, checksum-verified community plugins (AI providers, notification channels, event automations); write your own with a single Python file.
• MCP server — agents (Claude, Codex, …) can inspect cameras, events, and health and run guarded admin workflows, over a stateless (session-free) HTTP endpoint or local stdio; see docs/mcp.md.
• Tailscale-native — secure access over your tailnet; fully usable on a LAN too.

Multi-host: every camera, from any device

Install TailCam on more than one machine on the same tailnet (a Raspberry Pi, a Mac, a Linux box…) and each node automatically discovers the others and shows all of their cameras. Open the dashboard on any device and you see every camera across your tailnet in one place — no matter which machine the webcam is physically plugged into.

How it works:

• The node you're viewing becomes an aggregator: it finds the other TailCam nodes, asks each for its camera list, merges them, and reverse-proxies the remote video and controls — so your browser only ever talks to the node you opened (one origin, one Tailscale cert).

• Discovery is automatic over Tailscale (it probes online tailnet peers for a running TailCam). You can also list peers explicitly:

  # ~/.config/tailcam/config.toml
  [peers]
  auto_discover = true
  static = ["https://tailcam-pi.your-tailnet.ts.net:8443"]   # optional explicit peers
  

• Name a node with TAILCAM_HOST (otherwise its Tailscale MagicDNS name / hostname is used), e.g. TAILCAM_HOST=garage-pi.

• GET /api/hosts lists every node (local + peers) and their camera counts.

Choose what runs on each node

The 1.9.0 source builds add Settings → Node purpose and CLI presets. For a manual install, configure a hub before its first startup:

tailcam config --init --preset hub --node-name "Workshop hub"
tailcam run

Presets: all-in-one (default), camera (capture + storage), hub (fleet dashboard/control), storage, and compute (analysis + training). For custom combinations, use --roles capture,storage or the independent Settings switches. Use --roles capture when a camera should stream and send recordings elsewhere.

Roles take effect on server restart; Settings shows saved and active roles. Valid older configs keep all four roles. The node UUID survives config changes and restarts, while existing host/proxy links keep working. These are workload roles, separate from viewer/operator/admin permissions. Hub startup skips camera scans and local models; the base package still includes OpenCV. Role-aware OS installer prompts and lean packaging remain follow-up work. The current OS installers start all-in-one on a fresh install; use manual setup for a hub's first startup.

Storage node: record on the machine with the disk

Every node can send its own cameras' recordings, motion clips, and timelapses to a different node. Pick it in Settings → Recording & storage (each node's free space is shown) or set [storage] node = "nas-box". The storage node pulls the camera's MJPEG stream over the tailnet and runs the recorder/timelapse worker itself, so the files land on its disk and a Raspberry Pi never encodes video. Connectivity fallback can save locally only with the source's storage role enabled. A destination's disabled-role refusal never falls back. The picker marks nodes whose storage role is off. The storage node's save folder can be browsed and set from any dashboard.

Detection node: run the models where the CPU is

In AI Studio → Object detection → Run detection on, pick another node. Frames from this node's cameras are sent (downscaled, about 50 KB, at most once a second per camera) to that node's POST /api/detect-image, which answers with boxes and motion labels from its pipeline. The sending node never loads a model. Ollama already works the same way via its base_url.

Notes:

• Remote cameras are fully viewable and controllable (resolution, stream settings, zoom/pan, snapshot, record, timelapse).
• The gallery, events, and timelapse list are fleet-wide — anything captured on any node shows up (and can be stopped or deleted) from any dashboard.
• This treats every TailCam node on your tailnet as trusted — the intended model for a personal tailnet (there is no separate auth; Tailscale is the security boundary).
• Linux, macOS, and Windows nodes all participate in the same tailnet dashboard.

Local AI

Object detection — built in, zero setup

Open any camera and TailCam draws live bounding boxes with labels — person, cup, bottle, cat, dog, and the rest of the 80 COCO classes — using a built-in detector that's on by default (off by default on a low-power host such as a Raspberry Pi — route it to a bigger node instead) and runs entirely on your hardware. The model (a few MB of YOLO) downloads itself the first time it's needed; nothing to install or configure. Motion events are labeled from the same detector, so the Events page gets PERSON / DOG / CUP chips out of the box. Turn it on or off per camera, and tune it (confidence, class filter, engine, bigger models, which node runs it) in AI Studio → Object detection or the [detection] config section.

AI motion analysis — local, optional

Motion detection is free pixel-diff; when it fires, TailCam can ask a local Ollama vision model to label the event (person / animal / vehicle / package / …) with a short description — no cloud. Because cheap motion gates the model, it's only consulted a frame or two per event, so one machine can analyze the whole fleet.

Set up (e.g. on a Mac mini):

# Install Ollama and pull a vision model (moondream is small + fast):
ollama pull moondream          # or: qwen2.5vl / llava for better labels

Then enable it from the dashboard: open AI Studio → Models, flip Motion AI (Ollama) on, set the model and the Ollama URL (http://localhost:11434, or a tailnet host like http://mac-mini.your-tailnet.ts.net:11434 to analyze the whole fleet), and hit Save & test — no restart, no config file. The panel shows whether Ollama is reachable and the model is pulled. (You can still set [ai] in config.toml if you prefer.)

Motion events then show a label chip (🧍 person, 🚗 vehicle…) + the trigger thumbnail. To let one node analyze another's events, point the URL at that node (and run Ollama with OLLAMA_HOST=0.0.0.0 so the tailnet can reach it). See AI analysis for current usage. The original AI roadmap is retained as historical design context.

Train your own — and let the loop label for you

Collect and label footage from your own cameras, then fine-tune a private model on your Mac/Windows GPU (optional tailcam[training] extra). Build either a classification model (one label per frame) or an object-detection model — draw bounding boxes (where and what) right in the dashboard, train a YOLO detector, and overlay live boxes on any camera.

With active learning, a labeling model (built-in YOLO, your trained model, Ollama, Florence-2, or Qwen2.5-VL) watches your cameras, auto-labels confident detections, and sends only the uncertain frames to Label Studio for you to review; synced annotations fine-tune YOLO, Florence-2, or Qwen2.5-VL (via Unsloth, CUDA). One click in AI Studio → Active Learning; see the in-app Docs → Active learning page.

AI agents (MCP)

TailCam ships an MCP server, so agents like Claude Code and Codex can inspect cameras, events, and node health — and run guarded admin workflows — over tailcam mcp stdio or the authenticated /mcp HTTP mount. The MCP page in the dashboard generates ready-to-paste connection snippets for each agent.

The HTTP endpoint is stateless: no Mcp-Session-Id, nothing kept between requests, every POST a self-contained exchange. There is no session to resume or expire, so restarting a node never strands a connected agent, and an agent can call a tool without replaying initialize first. Each request states its own revision in the MCP-Protocol-Version header, and authorization is re-derived from the live Tailscale principal every time — so there's no session token to steal or replay, and a revoked role takes effect on the agent's next call. Clients that send a session id anyway are simply ignored, never bounced.

See docs/mcp.md and docs/mcp-security.md.

Plugins & marketplace

TailCam is extensible: AI providers, notification channels, and motion-event automations are plugins. Open Plugins in the nav to browse the curated marketplace — Slack and ntfy.sh alerts, an OpenAI-compatible analyzer (LM Studio / llama.cpp / OpenRouter / OpenAI), a motion-event logger — and install with one click. Every marketplace file is reviewed and sha256-verified at install time, installs hot-load without a restart, and everything runs locally.

Building your own is one Python file with one import (tailcam.plugins.sdk) — see the in-app Docs → Plugins authoring guide and marketplace/ for the template + contribution process. Community plugins land in the registry via reviewed pull requests.

Browser extension (optional)

TailCam Companion brings the dashboard into your browser chrome — strictly an enhancement, never a requirement. One shared WebExtension codebase ships for Chrome, Edge, Firefox, and Safari (Manifest V3, no frameworks, no third-party servers, no analytics):

• Toolbar mini-dashboard — live camera thumbnails across all your nodes, one-tap snapshot/record, and the latest motion events with their AI label chips.
• Badge + notifications — unseen-event count on the toolbar icon; native notifications filterable to labeled-only or person-only, with quiet hours.
• Glance window — pop any camera into a small floating viewer and keep working.
• Omnibox — type tc <camera name> in the address bar to jump straight to it.
• Keyboard shortcuts — open the dashboard or glance your pinned camera.

The extension talks directly to the nodes you configure (over your tailnet), and host permission is requested per node at runtime. Source, build script, and per-browser install instructions live in browser-extensions/.

CLI

Tab-completion: tailcam --install-completion. tailcam --version prints the version.

Ports & Tailscale

There are two separate ports:

• server.port (default 8088) — the local web UI: http://localhost:8088/.
• tailscale.serve_port (default 8443) — the tailnet-facing HTTPS port.

TailCam serves on https://<host>.<tailnet>.ts.net:8443/ by default rather than the root (:443), so it won't clobber another app (e.g. OpenClaw) already served at the root URL. Tailscale permits 443, 8443, and 10000 for serve/funnel.

To change the tailnet port:

tailcam tailscale serve --https-port 10000   # one-off + saved to config
# or edit ~/.config/tailcam/config.toml  ([tailscale] serve_port = 10000) and restart the service

If TailCam previously grabbed the root URL and you want it back for another app:

tailcam tailscale serve-off --https-port 443   # removes only TailCam's :443 handler

Security model

TailCam's boundary is your Tailscale network: the server binds to 127.0.0.1 and is reached over your tailnet, with no per-request login. On top of that, TailCam ships defense-in-depth:

• Cross-origin / drive-by protection — state-changing requests (snapshot, record, delete, settings) from a foreign web origin are rejected; only localhost and your tailnet (*.ts.net) may mutate. This stops a malicious site you visit from poking your local TailCam (CSRF / DNS rebinding).
• Security headers on every response — Content-Security-Policy (same-origin only), X-Frame-Options, X-Content-Type-Options: nosniff, Referrer-Policy, Permissions-Policy.
• No SSRF amplification — the peer reverse-proxy does not follow redirects.
• Anti-DNS-rebinding — state-changing requests are accepted only when the Host is loopback, an IP literal, or your tailnet (*.ts.net); a rebound attacker hostname is rejected.
• Secrets (MQTT password, HomeKit pin, Tailscale keys) live in config.toml, written 0600 in cleartext — secure your backups and support bundles accordingly.
• No TailCam account or hosted camera service. Update checks, package/plugin/model downloads, and Tailscale setup contact their respective services. Optional notification and AI-provider plugins can send events or frames to the endpoints you configure; review those integrations before enabling them.

Keep the default 127.0.0.1 bind — don't expose TailCam directly to a public network; let Tailscale handle access.

Architecture

One capture thread per camera publishes the latest frame into a lock-light FrameBuffer; FastAPI serves an MJPEG stream (multipart/x-mixed-replace) with JPEG encoding offloaded to a thread pool so the event loop never blocks. The streaming layer sits behind a StreamBackend abstraction, so a low-latency WebRTC backend can be added later without changing capture or the web layer. Settings live in a TOML config; the camera registry, media index, and motion events live in SQLite.

Development

python3 -m venv .venv && source .venv/bin/activate
python -m pip install -e ".[dev,homekit,mqtt]"
TAILCAM_SYNTHETIC=1 tailcam run    # run without a physical webcam
pytest                             # tests use a synthetic camera, no hardware needed
ruff check src tests && mypy src/tailcam

Set TAILCAM_SYNTHETIC=1 to use a built-in synthetic camera source — useful on headless servers, in containers, and in CI where no webcam exists.

The dashboard front-end lives in web-ui/ (React + Vite). Its build output is committed to src/tailcam/web/spa/ and ships in the wheel, so end users never need Node. Dashboard development requires Node.js 22 or newer; CI and the Docker build use Node 22. To change the UI or in-app docs: cd web-ui && npm ci && npm run typecheck && npm run build, then commit both the source and the regenerated src/tailcam/web/spa/. Run npm audit after dependency changes and follow the dashboard development guide for browser checks.

Releases: bump __version__ in src/tailcam/__init__.py and the version in web-ui/package.json, web-ui/package-lock.json, and all four browser-extensions/*/manifest.json files (keep them identical) with every change merged to main; tests enforce they match. Update the extension options-page version label too. The version is shown by tailcam version (and tailcam --version), tailcam status, /api/system, and the dashboard Settings page — it's how you confirm a node is actually running the build you think it is.

Publishing a release

PyPI publishing uses GitHub Trusted Publishing through .github/workflows/pypi-publish.yml and the pypi environment; no PyPI API token is needed. The project already exists at PyPI, so maintain its publisher under the project's publishing settings rather than creating another pending publisher.

1. Bump the version, rebuild any changed dashboard/docs, and run the checks above.
2. Build and validate the distributions: python -m pip install build twine, then python -m build and python -m twine check --strict dist/* in a clean checkout.
3. Merge the PR, then publish a GitHub Release whose vX.Y.Z tag points to that merged commit. The tag must match the package version; the workflow does not bump or validate the version for you. Alternatively, run Publish to PyPI manually from main once for that version.
4. Confirm the workflow succeeds and python -m pip index versions tailcam shows the new version. Test installation in a fresh virtual environment.

Merging alone does not publish to PyPI. Avoid uploading the same version via both triggers: PyPI rejects reusing distribution filenames. The PyPI description comes from the README packaged with each release; editing GitHub's README does not change an already uploaded distribution.
