【Plug-and-Play, Streamlined Workflow】- Connect Vcore to your camera via HDMI and to your phone via USB-C. With the HollyView app, your phone instantly becomes a real-time wireless monitor, supporting 4K 30 fps ultra-low latency transmission with exceptional image quality. With a built-in 5150mAh battery, Vcore can charge your monitoring phone simultaneously. *Note: The HDMI cable must be purchased separately based on your camera model. The HollyView App could be downloaded via Google Play (App Store) for Android (IOS) devices.

【Pro-Grade Proxy Recording, Seamless Post-Production Integration】- Vcore supports recording at up to 1080p 60fps with H.264 encoding and intelligently detects the camera’s frame rate and timecode. The resulting MP4 proxy files can be seamlessly linked with original footage, offering full compatibility with mainstream editing software such as Premiere Pro and DaVinci Resolve — significantly enhancing post-production efficiency.

【Dual-Backup Recording: Security and Convenience Combined】- Vcore supports simultaneous dual-path recording: on one hand, it saves proxy files with embedded timecode to the internal SD card (requires separate purchase) as a reliable backup; on the other hand, it enables synchronous MP4 recording on mobile devices via the HollyView app, facilitating quick editing and instant social sharing — making it especially ideal for fast-paced shooting scenarios.

【Lossless Format Instant Transmission】- By connecting the camera via a data-transfer USB cable (charging-only cables not supported), Vcore automatically captures uncompressed original files such as RAW and JPEG as you shoot. These files are wirelessly transmitted in real time to mobile devices (via the HollyView app) and computers (macOS/Windows systems via the HollyLink plugin for Capture One), truly achieving "shoot-and-transfer" functionality.

【Wired and Wireless Dual Modes with Free Switching】- Vcore supports simultaneous wired connection to your camera while wirelessly linking to smartphones or tablets via the 5GHz band, enabling real-time remote monitoring. The wireless transmission range extends up to 100 meters (line of sight) with a low latency of approximately 65ms, delivering smooth 1080p 60fps video quality.

Lightweight yet powerful, Vcore is more than just a video transmission system - it's your creative companion, keeping you in perfect sync with your vision while streamlining and simplifying both your setup and post-production. Imagine crystal-clear 4K30 monitoring in the palm of your hand. Your mobile device instantly becomes a professional-grade portable monitor, powered by our intuitive HollyView app. This revolutionary transmission system seamlessly merges HD monitoring, image transfer and versatile recording capabilities, empowering creators to see everything and create anywhere. *Note: The HollyView App could be downloaded via Google Play (App Store) for Android (IOS) devices.
