Newly launched KA2 PLUS and KA2 PRO
Newly launched KA2 PLUS and KA2 PRO
The KA2 is a purpose-built hardware platform that combines a Full HD 100° wide-angle camera, far-field microphone array, and Google-certified Android TV box into a single compact device. Designed for brands and retailers looking to enter the smart elderly care, enterprise video conferencing, or smart home markets without building hardware from scratch.
With 14 years of OEM/ODM manufacturing experience and proven mass-production capability, Videostrong delivers KA2 with full customization: firmware, software, branding, packaging, and accessories — tailored to your product requirements and target market.
KA2 is already deployed across 60+ countries. Whether you need 500 units for a pilot or 100,000 units for a retail launch, our engineering team is ready to support your go-to-market timeline.
- FHD 1080P 100° Ultra-Wide Camera — covers the entire living room; no repositioning needed
- 5-Meter Far-Field Mic Array — clear voice pickup across large spaces, certified by Google
- One-Button Video Calling — no app navigation, no complicated setup; designed for elderly users and non-tech-savvy audiences
- Auto TV Wake-Up (CEC) — incoming calls automatically turn on the TV; no remote required
- Hardware Privacy Switch — physical kill switch for camera and microphone; builds end-user trust
- Built-in 5W Speaker — loud and clear audio for living room environments
- Google Assistant Built-In — voice control for smart home devices, streaming, and search
- Full Android TV Experience — YouTube, Disney+, Prime Video, and custom app preloads available

- Firmware & Software: Custom launcher, preloaded apps, UI branding, OTA update infrastructure
- Hardware Variants: KA2 SE (camera + mic), KA2 PLUS, KA2 PRO — different feature tiers for different price points
- Industrial Design: Custom housing color, logo engraving, packaging design
- Certifications: CE, FCC, RoHS — documentation support included
- Cloud Integration: Compatible with third-party video call platforms (WhatsApp, Zoom, proprietary apps)
Our engineering team will assess your requirements and return a tailored proposal within 3 business days.

Smart Elderly Care
The KA2 solves the core problem in elderly-focused products: complexity. Seniors don't need to navigate menus or pair devices. One button answers or makes a call. The TV turns on automatically. The 100° wide-angle camera means they don't have to sit perfectly still. For brands building elder care solutions in Japan, Europe, or North America, KA2 provides a hardware foundation that reduces onboarding friction to near zero.
Enterprise & Hotel Video Conferencing
For hospitality groups and enterprise clients, KA2 replaces the traditional setup of a separate camera, microphone, and set-top box with a single device. The far-field microphone array handles meeting rooms up to 5 meters. Custom firmware allows integration with proprietary communication platforms or hotel management systems.
Smart Home Hub
With Google Assistant built in and ZigBee-compatible gateway options available, KA2 can serve as the central control node for smart home ecosystems — controlling lighting, thermostats, locks, and other connected devices entirely by voice.
