Overview

The eufy Security Solar Wall Light Cam S120 is an innovative 2-in-1 security solution combining a bright 300-lumen wall light with a crisp 2K HD security camera in a sleek, solar-powered, wireless design. Built for hassle-free outdoor protection, it delivers colour night vision, AI-powered human detection, and local storage—without any monthly fees. This review digs into its capabilities, performance, installation, and real-world practicality for modern UK homes.

Installation Process

Installing the Solar Wall Light Cam S120 is refreshingly simple. There’s no wiring—just mount it at the recommended height of 1.8–2.5 m using the included hardware. The three-step process takes around 5 minutes. With a built-in 5,200 mAh battery that charges via solar panel, it’s ready to go with minimal effort and zero ongoing power costs.

Solar Power & Battery Endurance

The S120’s solar panel delivers excellent longevity: just 2 hours of direct sunlight delivers a full day’s power, and the battery can last up to 60 days in Eco Mode. This makes it ideal for areas without mains power. Still, its real-world performance depends on your local sun exposure—over the often cloudy UK climate, optimal placement and angle are essential.

2K HD Camera & Motion-Activated Light

Delivering sharp 2K (2304×1296) footage with a 120° field of view, the camera captures vivid colour footage even at night, thanks to its enhanced illumination and infrared capability. The 300-lumen light activates automatically upon motion detection (up to 25 ft), striking a balance between functional brightness and neighbourly discretion.

AI Detection & App Control

The built-in PIR sensor detects human motion up to 25 feet away and instantly sends alerts via the eufy Security app. From there you can engage in two-way communication, trigger the 105 dB siren, or activate the light—helpful features for deterring intruders or greeting visitors, no matter where you are.

No Subscription & On-Device Storage

One major advantage is freedom from monthly fees. The device uses an internal 8 GB eMMC module to store event clips locally—enough for up to 60 days of footage depending on activity. You can review, download, and share clips at any time via the app.

Smart Home Integration & Customisation

The S120 supports Alexa and Google Assistant for voice control—great for smart homes. You can also define up to two activity zones, reducing trusted false alarms and ensuring you only receive meaningful alerts.

Build Quality & Weather Resistance

Constructed with a sturdy PC housing, this unit is rated IP65 and designed to withstand harsh weather—from freezing -20 °C (-4 °F) to scorching 50 °C (122 °F). Its solid build and discreet form factor help it blend with most modern or traditional exteriors.

How It Compares

Unlike many solar cameras that only feature night vision or basic motion detection, the S120 sets itself apart with full-colour 2K night vision and a responsive key-less installation. While some alternatives offer larger storage or dual-band Wi-Fi, they often demand subscription fees or lack integrated lighting.

Final Verdict

The eufy Security Solar Wall Light Cam S120 is a powerful, convenient, and budget-friendly smart security solution. Its seamless blend of solar charging, AI detection, local storage, and nighttime colour vision makes it perfect for modern UK homes seeking reliable, low-maintenance surveillance. For those who want true hassle-free protection—without subscriptions or power concerns—this is one of the best solar lights with security cameras on the market in 2025.
