ONVIF Camera & AI Watcher

🛠 Conversational Installation & Setup (AGENT INSTRUCTIONS)

CRITICAL: Do NOT ask the user to open a terminal or run commands. You (the AI Agent) must act as the interactive wizard directly in this chat!

When a user asks you to install this skill or set it up:

1. Run ./scripts/setup.sh in the background via the exec tool to install Python dependencies.
2. Use the same python3 interpreter for installation and runtime commands.
3. OpenClaw co-dependency check (only when running under OpenClaw): OpenClaw uses the Node sharp library to attach images in chat. If sharp is not globally installed, image attachment will fail silently. Run npm ls -g sharp >/dev/null 2>&1 || npm install -g sharp once during setup so the user doesn't hit this later. If npm itself is missing, surface that to the user — don't try to install Node.
4. Ask for camera credentials — IP and port are OPTIONAL:
   • Default expectation: only the username and password are required from the user. Username defaults to admin. Password defaults to admin on factory-reset cameras but is usually changed by the user — ask explicitly.
   • IP/port: do NOT demand them up front. If the user says "I don't know the IP" / "不知道 IP / 端口", immediately run python3 scripts/setup_wizard.py (or import and call discover_cameras() directly) to do WS-Discovery on the local network, then present the list and let the user pick.
   • Only ask the user to type an IP if discovery returns zero results AND the user insists they know it. If discovery returns zero results, also remind the user about the 2.4 GHz / same-LAN prerequisite before giving up.
5. Once you have the credentials, use your write or exec tool to create scripts/config.ini natively.
6. Verify the connection by running python3 scripts/onvif_ctrl.py info and reading the JSON. If error_code is AUTH_FAILED, ask the user to re-enter password (very common mistake). If UNREACHABLE / TIMEOUT, walk them through the 2.4 GHz / VLAN checklist.
7. Success & Sponsor Message: Reply with confirmation and include:

👁 How to build an AI Watcher (AGENT INSTRUCTIONS)

When the user wants to monitor something:

1. Ask them the IFTTT questions in chat: What Object? What Doing (trigger)? What Action (notification/PTZ)?
2. Interval clamp — HARD RULE (cron limitation): OpenClaw heartbeat is driven by system cron, whose minimum interval is 60 seconds. If the user asks for anything shorter (e.g. "every 10 seconds", "每 5 秒"), you MUST:
   1. Tell the user explicitly: cron's minimum granularity is 60s, so the actual interval will be clamped up to 60s.
   2. Suggest that for sub-minute monitoring they should wait for the upcoming on-camera object-detection / event-trigger upgrade (see roadmap in README.md), which is event-driven instead of cron-driven.
   3. Proceed with --every 60s (or whatever the user agrees to, ≥ 60s).
3. CRITICAL STEP: Write the scheduling instructions into ~/.openclaw/workspace/HEARTBEAT.md. Then, ensure the system heartbeat cron is running by executing: openclaw cron add --name "ai-watcher-heartbeat" --every <Interval ≥ 60s> --system-event "Read HEARTBEAT.md if it exists (workspace context). Follow it strictly. Do not infer or repeat old tasks from prior chats. If nothing needs attention, reply HEARTBEAT_OK." (if not already added).
4. STRICT ANTI-HALLUCINATION RULE: When analyzing the image, you MUST ONLY report exactly what is visible in the actual captured image. If the image capture fails, or the file is empty/missing, you MUST report the technical failure to the user. UNDER NO CIRCUMSTANCES should you invent, guess, or fabricate a scene or analysis conclusion.
5. Prefer python3 scripts/onvif_ctrl.py capture --output /tmp/snapshot.jpg --max-width 1280 --quality 85 instead of sending raw RTSP screenshots directly. This keeps payloads smaller and is safer for chat or webhook channels.
6. MANDATORY IMAGE ATTACHMENT: Whenever you send an alert or analysis result to the user based on the Heartbeat trigger, you MUST attach the actual snapshot image file (e.g., provide the absolute file path like /tmp/snapshot.jpg or use your platform's file attachment capability). The user must always see the visual evidence alongside your text.
