Smart Glasses Without a Camera: Halliday’s G2 Finally Puts Privacy First
For years, the smart glasses market has been defined by a single, controversial feature: the camera. Devices like Meta’s Ray-Ban smart glasses promised a hands-free future of photos, videos, and AI vision, but they also created a new social problem. Wearers often found themselves answering the same uncomfortable question in offices, restaurants, and public spaces: “Are you recording me?” Privacy advocates raised alarms, workplaces restricted the devices, and the term “pervert glasses” entered the conversation after repeated reports of covert filming.
Against that backdrop, a quieter trend has been building. A growing number of companies are deliberately designing smart glasses without cameras, betting that useful AI does not require a lens pointed at the world. Halliday’s newly announced G2 is one of the clearest expressions of that philosophy. Priced at $599 and scheduled to ship in September 2026, the glasses are built for professional environments where discretion and productivity matter more than content creation.
A Deliberate Design Choice
The Halliday G2 looks like a conventional pair of glasses. There is no visible camera module, no recording light, and no bulky sensor package that signals “this device is watching.” Instead, the frames house a binocular waveguide display driven by dual micro-LED projectors. Each eye receives a 600-by-300 monochrome green image with peak brightness reaching 1,600 nits. The display sits in the upper portion of the field of view so information can be glanced at without breaking eye contact during a conversation.
Auto-dimming reduces brightness in darker rooms, and a “stealth mode” further lowers the light output to avoid distracting others. The company targets a weight under 50 grams and supports prescription lenses, making the G2 a realistic everyday wearable rather than a novelty device worn only for short periods.
Audio is handled by a four-microphone array designed to pick up conversation from roughly two meters away while distinguishing the wearer’s voice from others at the table. Open-ear speakers deliver calls, notifications, and media without sealing the ears. Battery life is rated at approximately 12 hours of typical use. Controls include a long touch bar on the temple and a programmable action button, supplemented by voice commands using the wake phrase “Hey Halliday.”
The absence of a camera is not an oversight. Halliday explicitly markets the G2 as a professional tool suited for meetings, client conversations, and secure workplaces where recording devices are unwelcome or restricted. By removing the camera, the company also reduces weight, improves battery efficiency, and sidesteps many of the social and regulatory complications that have dogged camera-equipped competitors.
Meeting Flow: AI That Works in Real Time
Hardware alone does not define the G2. The core software feature is Meeting Flow, an AI system designed to assist during conversations rather than simply archive them afterward. When activated, the microphones listen to the discussion and the system surfaces relevant information directly on the display.
Live captions appear for the wearer, and real-time translation supports more than 45 languages. If a speaker drifts off topic, Thread Tracker flags the shift. Decision Confirmation and Commitment Check highlight unresolved action items or verbal agreements that might otherwise be lost. Short research lookups and quick recaps can appear if the wearer loses the thread of a complex discussion. After the meeting ends, the companion app generates structured summaries and full transcripts.
A teleprompter-style mode called Cheatsheet keeps key talking points or daily reminders visible. Outside formal meetings the glasses handle notifications, phone calls, music, and general AI assistance. The system is intended to keep the wearer engaged in the room rather than looking down at a laptop or phone.
These capabilities are powered by a combination of on-device processing and cloud services. A free tier provides limited recording time, while paid subscription plans ranging from roughly $10 to $99 per month unlock higher usage limits and more advanced features. Halliday positions the G2 as a tool for high-performance professionals—founders, executives, consultants, and others who spend significant portions of their day in meetings.
Privacy as a Product Feature
The decision to omit a camera reflects a broader recognition that visual recording creates unique risks. Camera-equipped glasses have been used to capture people without consent, and the resulting footage has sometimes been processed by third-party annotation services, raising further questions about data handling. Even when recording indicators are present, many bystanders do not notice or understand them.
Halliday’s approach does not eliminate all privacy considerations. The microphones can still capture audio, and the company advises users to disclose recording, just as they would with any other device. There is no always-visible indicator light for bystanders when the microphones are active. Still, the absence of a camera removes the most invasive and socially charged capability. In environments with strict recording policies or cultural sensitivity around visual surveillance, camera-free glasses become far more acceptable.
This design choice also improves practical usability. Without a camera, the frames can be lighter and less power-hungry. The glasses are less likely to trigger security protocols in corporate offices, government buildings, or client sites that prohibit recording devices. For users who simply want translation, captions, or meeting assistance, the camera was never necessary in the first place.
A Market Splitting in Two
Halliday is not operating in isolation. Even Realities has built its brand around camera-free display glasses focused on productivity and discretion, raising substantial funding and attracting users who prefer not to wear a camera on their face. Other manufacturers, including Solos and Lucyd, have introduced camera-less models or physical privacy covers for devices that do include cameras. The common argument is that the most frequently used smart-glasses features—notifications, translation, voice assistance, transcription, and navigation prompts—rely primarily on audio and display rather than computer vision.
Meanwhile, the dominant players continue to invest in camera-equipped devices. Meta’s Ray-Ban line remains the volume leader, and other companies are racing to add color displays and more advanced visual AI. The result is a clear bifurcation in the market. One path prioritizes capture, content creation, and visual understanding of the environment. The other prioritizes discreet information delivery, professional utility, and social acceptability.
Halliday’s G2 sits firmly in the second camp. It competes more directly with Even Realities’ G2 than with Meta’s offerings. Both devices use monochrome waveguide displays, emphasize lightweight frames, and target users who value productivity over photography. Differences appear in software focus, battery claims, speaker design, and pricing strategy, but the underlying philosophy is similar: smart glasses can be useful without becoming surveillance devices.
Practical Considerations and Open Questions
Early reviews of Halliday’s first-generation product were mixed, with criticism directed at display visibility and overall refinement. The G2 represents a substantial hardware upgrade—moving from a single-eye near-eye display to binocular waveguides and higher brightness. Real-world performance of the microphones in noisy environments, the accuracy of Meeting Flow’s AI summaries, and the comfort of all-day wear will determine whether the device succeeds.
Battery life of 12 hours is respectable for a display-equipped wearable but shorter than some pure-audio competitors. Subscription costs for full AI features will add to the total cost of ownership. Prescription lens options expand the potential user base, yet the monochrome green display may feel limited compared with emerging full-color systems.
Accessibility benefits are worth noting. Real-time captions and translation can assist people who are hard of hearing or operating in multilingual settings. The ability to receive information without looking away from a conversation or presentation has clear value in professional contexts. Whether these advantages outweigh the limitations will become clearer once units reach customers in volume.
The smart glasses category is still young. Major technology companies continue to invest heavily, and form factors, battery technology, and display systems are evolving rapidly. At the same time, regulatory and cultural pressure around wearable cameras is unlikely to disappear. In Europe and parts of Asia, data-protection rules already constrain how such devices can be used in public and workplaces.
Halliday’s G2 arrives at a moment when the market is ready to test an alternative. By removing the camera and focusing on real-time meeting assistance, the company offers a product that many professionals can actually wear without social friction. It is not a universal solution, nor is it intended to replace camera-equipped glasses for users who want visual capture. It is, however, a coherent answer to a persistent problem: how to deliver useful AI on the face without making everyone else uncomfortable.
If the software delivers on its promises and the hardware proves comfortable for long days, camera-free designs like the Halliday G2 may represent more than a niche. They could become the practical default for people who spend their working lives in conversation rather than content creation. In a category long dominated by the allure of the camera, the decision to leave it out may prove to be the smarter move.
