Selfie Monitor Screen for iPhone Rear Camera - Vlog & Live

In this review of the Synco Xview M4 the bottom line is simple: creators who want sharper rear-camera selfies and reliable wireless monitoring will find a compact, well thought-out tool. The XView M4 turns your phone's rear camera into a true vlogging monitor with a bright 480P display and ultra-low 40ms latency, making framing and audio checks practical while shooting. The magnetic attachment and 3 hour battery life make it easy to use on the go, and the clear wireless link means fewer retakes when recording solo content.

Key Features

• Rear camera monitoring: Lets you use your phone's back camera for higher image quality and more vibrant results compared with the front camera.
• Ultra-low latency: 40ms delay provides smooth, near real-time preview so framing and movement look natural while recording.
• Strong magnetic mount: N56 neodymium magnet secures the monitor to the back of the phone or a metal surface for a stable, slip-free fit.
• Long enough battery life: Built-in 1300mAh battery delivers about 3 hours of continuous use for extended shoots without frequent recharging.
• Wireless P2P link: SYNCO M4 P2P technology offers reliable transmission up to 164ft range under ideal conditions so creators can move while monitoring.
• Clear visuals and sound: 480P resolution and 400cd/m2 brightness with built-in speaker give a readable preview and basic audio monitoring on location.

Who It's For

The XView M4 is aimed at solo vloggers, TikTok and YouTube creators, and livestreamers who want to upgrade from a front-facing phone selfie to the superior rear camera without relying on a tripod or extra crew. Its magnetic attachment and lightweight design are convenient for quick setup and run-and-gun shooting where a compact monitor is more useful than a full rig.

It is less suited to users who need ultra-high resolution monitoring or multi-camera switching on a professional set; for those workflows a larger field monitor or dedicated HDMI setup will be a better fit. Also, creators who require more than roughly 3 hours of continuous runtime should plan for external power for longer sessions.

Pros & Cons

Pros

• Easy to attach and use with a secure N56 magnet for steady placement.
• Low 40ms latency makes live monitoring feel immediate and usable for movement-heavy shots.
• Good clarity and brightness at 480P and 400cd/m2 for outdoor or indoor framing.
• Battery and quiet operation are friendly to ASMR or low-noise shoots.

Cons

• 480P resolution is fine for framing but not a pixel-perfect reference for detailed color grading.
• About 3 hours runtime may require recharging for longer recording days.
