Synco XView M4 Phone Vlog Selfie Monitor - Rear Camera Live View

In this review of the Synco XView M4, the bottom line is simple: creators who want sharper, more vibrant phone footage without juggling a tripod will appreciate this compact rear camera monitor. It lets users monitor the phone's back camera in real time with low latency so framing and exposure feel immediate, and the built-in speaker and Bluetooth remote add practical control for live streaming and vlogs. For anyone tired of the limitations of front-facing selfies, the XView M4 offers a focused solution that improves image quality and on-the-go workflow.

Key Features

• Rear camera monitoring: Using your phone's back camera delivers sharper, higher-quality images than a front camera for more professional-looking video and photos.
• Ultra-low latency: The 40ms latency provides near real-time feedback so movement and audio stay synchronized during recording and live streams.
• Secure magnetic mount: A powerful N56 neodymium magnet makes attachment to the phone or a metal surface quick and stable for hands-free shooting.
• Wireless P2P transmission: P2P technology maintains an uninterrupted connection up to about 164ft in open environments, even when the phone uses WiFi.
• Portable power: The 1300mAh battery supports roughly 3 hours of continuous use while consuming just 1.75W, suitable for extended shoots without heavy power drain.
• Readable display: 480p resolution and 400cd/m2 brightness deliver clear images and accurate colors in both bright and low-light conditions.

Who It's For

The XView M4 is best for vloggers, live streamers, and mobile content creators who want to use their phone's rear camera for superior image quality while still monitoring framing and audio. Its small size and magnetic mount make it a good fit for handheld shooting, quick set-ups, and creators who move between locations.

It may be less attractive to users who require higher resolution monitoring or multi-camera broadcast setups; professionals needing 1080p or larger monitoring would look for a more advanced field monitor. Casual selfie takers who prefer the simplicity of the front camera might also find it more capability than they need.
