What Is an AI Pendant with Camera?
An AI pendant with camera is a small wearable voice assistant that hangs around the neck, combines a built-in camera, microphone, speaker, and wireless connectivity, and uses on-device or cloud-based artificial intelligence to interpret the surrounding world and respond to spoken commands without needing a phone in hand. This new hands-free AI device category aims to bring context-aware computing into daily life by pairing voice interaction with real-time visual input. Unlike smart speakers or phone-based assistants, an AI pendant camera can see what the wearer sees, respond to wake words, and deliver spoken feedback through integrated audio hardware, while remaining more discreet than smart glasses and light enough for all-day use.
ESP32 AI Pendant: A DIY Wearable Voice Assistant
The ESP32 AI Pendant project shows how hobbyist hardware can become a fully featured wearable voice assistant. Built around the Seeed Studio XIAO ESP32S3 Sense board and Xiaozhi firmware, it combines an onboard microphone, a small speaker, camera support, Wi-Fi, and an RGB NeoPixel ring in a compact, 3D-printed enclosure. Users activate the assistant with wake phrases such as “Hi ESP” or “Jarvis”, then receive AI-generated voice replies through the pendant’s speaker. While the AI processing runs in the cloud, the pendant handles audio capture, playback, LED feedback, and network communication locally. A rechargeable LiPo battery and slide power switch support mobile use, while the camera and RGB lighting enable visual AI features and status effects. By omitting a display and relying on light patterns instead, the design stays pocket-sized and extends battery life, hinting at how minimalist AI pendants can stay always ready without a smartphone screen.
Lenovo’s Kid-Focused AI Pendant Camera
Lenovo’s new AI Companion Device applies the AI pendant camera idea to children, sitting somewhere between a kids’ smartwatch and a basic smartphone. The device has a rounded form and a 2.0-inch HD touchscreen protected with Panda Glass, plus two physical buttons: one for the AI assistant and one SOS key for emergencies. A 5MP camera on a rotating hinge lets kids take photos or start video calls, while a multimodal AI model uses that camera for object recognition of plants, animals, and everyday items and supports voice conversations, homework assistance, and bilingual learning tools. According to JD.com’s listing, the device uses 2GB of RAM, 16GB of storage, and an Android-based OS that supports apps such as WeChat, QQ, DeepSeek, dictionaries, and educational platforms. With Wi-Fi, Bluetooth, and 4G LTE via a SIM card, it works as a connected wearable voice assistant that parents can supervise.
Always-On Design: Batteries, Audio and Visual Feedback
Both the ESP32 AI Pendant and Lenovo’s AI companion highlight how careful hardware design turns AI pendants into practical, always-on wearables. The ESP32-based AI pendant uses a LiPo battery, lightweight 0.5W speaker, and Wi-Fi radio, all tuned to reduce power draw from audio playback, wireless activity, and the RGB NeoPixel ring so it can stay useful between charges. Lenovo’s kid-oriented device adds a magnetic charging system, daily reminder functions, and customizable watch faces, pointing toward AI pendants that double as schedule managers and notifications hubs. Built-in speakers and microphones make each pendant a hands-free AI device for natural voice interaction, while RGB lighting and small displays give visual cues without demanding constant screen time. Together, these choices show that AI pendants aim to stay active and connected without relying on a smartphone in the wearer’s hand or pocket.
Why AI Pendants Compete with Smart Glasses
By combining wearable voice assistant functions with a compact AI pendant camera, these devices compete with smart glasses while avoiding many of their social and comfort drawbacks. Pendants hang at chest level, which makes it easier to include lenses and sensors for object recognition without pointing a camera directly at someone’s face, and they can be worn over clothes or tucked under them for more discretion. The ESP32 AI Pendant proves that a pendant can deliver sci-fi-style interactions—wake words, spoken answers, and contextual lighting—out of inexpensive hardware and open-source software. Lenovo’s device shows how a similar form factor can add GPS-style tracking, real-time location history, safety fences, and parental controls to support child safety. As camera-equipped pendants evolve, they are likely to expand visual AI skills such as translating signs, logging activities, or summarizing scenes, all while keeping hands and eyes free.
