Feature
SenseCAP Watcher Price Adjustment Announcement:
After careful evaluation, the pricing of SenseCAP Watcher has been thoughtfully adjusted to make it even more accessible.
💬 Feature 1: Simply Speak Your Command
Just speak to SenseCAP Watcher 🎙️ and tell it what to monitor. Whether it’s “Notify me when someone enters the room” or “Watch for my dog chewing paper,” it listens and acts.
-
Command via Push to Talk 🟢
-
Or use the SenseCraft App 📱
You can easily send commands by Push to Talk or from SenseCraft App.
👁️ Feature 2: Understand What It Sees
Powered by on-device AI models, SenseCAP Watcher detects people, pets, objects, and more. But what truly sets it apart is its LLM integration 🧠.
-
Goes beyond detection: understands behaviors + context
-
Examples:
-
“Dog + playing ball, 0 people in room” 🐶⚽
-
“Person in DHL outfit arrived” 👕📦
-
-
Efficient hybrid architecture:
-
On-device AI filters keyframes
-
LLM analyzes only relevant scenes
-
Reduces cost while boosting precision 💡
-
Constantly calling LLMs like ChatGPT incurs a high cost. Hence, we use the architecture of on-device AI + LLMs . The on-device AI model on Watcher detects the target, which is then analyzed by LLM to generate accurate and actionable insights.
With the task "tell me if the dog is tearing up paper" when the on-device model detects dogs, this keyframe is sent to LLM for further analysis - is it tearing up paper? LLMs won't be triggered by people, cats, squirrel or others. This tremendously reduces LLMs' cost.
🔈 Feature 3: Respond via Voice
SenseCAP Watcher doesn’t just observe—it talks back!
-
Example scenario:
-
Event: Someone picks up the pink keyboard 🎹
-
Reaction 1: Voice reply — “Good choice! Inspired by the Pink Royal Typewriter.”
-
Reaction 2: Text alert to sales — “Someone’s interested in the latest keyboard!”
-
-
Other use cases:
-
“Stop, Cooper!” when dog tears tissues 🐾
-
“No smoking!” in restricted areas 🚭
-
🔌 Feature 4: Plug-In Power for Your Systems
SenseCAP Watcher integrates seamlessly with your smart ecosystem:
-
Triggers LED flashes 💡
-
Sends push notifications 📲
-
Connects to Home Assistant for contextual automation
-
Detects people → lights on for reading 📖
-
Detects sleep mode → lights off 🌙
-
Add Watcher to Home Assistant
Connected to IoT platform like Home Assistant, your Watcher acts as a behavior sensor, activating tailored actions in various contexts. For example, when it detects people, Watcher analyzes the situation and automatically triggers actions: lights on for reading and lights off for sleeping.
When someone sleeping + dim the light
More than a vision sensor, Watcher is extendable with other sensors to enable multi-modal sensing. On Watcher's back, the I2C is reserved to accommodate 100+ Grove sensors. This flexibility allows Watcher to integrate a wide range of data sources for thorough analysis and appropriate actions. You will be able to build applications like detect room temperature and adjust the AC accordingly - turn it to 22°C when you're in suits, or 26°C in shorts.
Add Watcher to your Node-RED flow
Just 3 blocks away, you can stream the detected results from your Watcher to any place on the internet via Node-RED, as easy as making a snap!
Add Watcher to your Arduino | ESP32 and other hardware systems
Wanna add an AI agent to popular MCUs and SBCs such as Arduino/ ESP32/ Raspberry Pi? Simply connect it to Watcher via UART or HTTP or USB, and you can explore the new frontier of intelligence.
Feature 5: Give Your Watcher Unique Emotions
SenseCAP Watcher adapts to your commands with unique "modes." It is LISTENING to your instructions, then shifts to WATCHING mode to safeguard your designated space, etc. But the fun doesn't stop here! You can upload your own designs of emotions to give your Watcher a unique personality. Get a PNG file ready and upload it to Watcher within seconds! It is your call!
Watcher's default emojis are inspired by C-3PO, paying tribute to one of our greatest helpers!
You can easily upload yours in .PNG format.
You can even custom design a unique UI (User Interface) for your SenseCAP Watcher. Our current UI is powered by Squareline.
Feature 6: Open Source and On-premise Deployment.
As an AI device, it is fundamental to respect privacy. And we embrace and implement two primary strategies in this nifty device.
- SenseCAP Watcher is open source, giving you full access to thoroughly understand how it works.
- It supports on-premise deployment. The backbone of SenseCAP Watcher is SenseCraft software suite, which is used to configure Watcher, interpret your commands, and access LLMs. Hence, everything is stored and running privately, ensuring that your models and data are not streamed to any public LLMs or public clouds. SenseCraft can run on Windows/ MacOS / Linux. Since SenseCraft contains LLMs, certain performance criteria are required for the computer, as follows.
You can deploy SenseCraft on your spare computers. However, if you aim for applications requiring commercial-grade reliability and low-power consumption, the combination of SenseCAP Watchter + NVIDIA® Jetson AGX Orin™ is perfect for you!
Compared to consumer-grade graphics cards (e.g. RTX 4090) for AI tasks, NVIDIA® Jetson AGX Orin™ stands out with key advantages:
- Industrial-grade reliability: Designed for industrial and commercial applications, Jetson AGX series boasts a longer MTBF (Mean Time Between Failures). Engineered for 24/7 operation, it offers superior reliability for round-the-clock applications compared to consumer graphics cards.
- Compact and low power: With embedded and edge computing applications in mind, Jetson AGX series are designed in a smaller form factor and consume 3+ times less power, compared to consumer graphics cards. Suitable for constrained spaces, Jetson AGX series generates less heat and helps reduce overall operating costs. This is crucial for embedded systems.
