Gadgets: Solar-powered security camera
Published in Science & Technology News
Eufy’s new solar-powered Wi-Fi Wall Light Cam S4 is as versatile a security camera as there is. It features almost everything you need in a do-it-yourself unit, producing a 4K crystal-clear resolution. Its flexible design enable it to be mounted on walls, rooftops, fences, etc.
Highlighting the most important features isn’t easy, since it’s loaded and some are stated as the industry’s first. This includes what Eufy calls groundbreaking radar-activated security, with the industry-first 60 GHz mmWave radar detecting motion with a 120-degree ultra-wide view and up to a 39.37-foot range. The technology is designed to reduce false alarms often triggered by pets.
The all-in-one security camera features a dual-purpose light that shines up to 500 lumens for security or to create atmosphere. It is triple-sided (left, right, and front) and can be tuned to white, warm or RGB lighting, with white tunable temperatures ranging from 2700K to 6500K. It works as a standard light and can shine when the security camera activates it. Once active, it will shine; flashing lights are included with a 120 dB siren.
The top-sided maintenance-free solar panel provides power. This gives the Wall Light Cam S4 two watts of solar power combined with the high-capacity 10,000 mAh battery, which will give you 40 days of reserve power. Eufy specs show that three hours of sunlight provide up to 24 hours of runtime.
Getting a security camera with all these features is rare when it also produces outstanding image quality. Behind the f/1.6 aperture ultra-wide-angle lens with an 8X zoom, the Wall Light Cam S4 has a viewing angle of 120 degrees. The 8 megapixel camera produces 4K clips and has a manually adjustable lens with a 45-degree vertical tilt.
Night vision is captured in color. The camera is built with AI-powered recognition to customize for pets, people and vehicles. All the settings and customization are done in the Eufy app. The Wall Light Cam S4 is also compatible with Apple HomeKit (via HomeBase), Alexa and Google Home.
It also features two-way audio, measures 9.65 by 3.22 by 5.42 inches, and is rated to work in temperatures from minus 4 degrees up to 122 degrees Fahrenheit. A mounting kit, with a bracket, is included. Without solar charging, the battery is rated to last two months of use.

BlueParrott’s new Pro B350 and Pro B450, professional-grade, AI-powered voice-isolation headsets are designed for extended wear and are aimed at users who spend long hours on calls, including those working from home or cross-country truck drivers.
Flip a coin on what you think is the most important feature for long-term wear headsets: comfort or sound. Equally important, but comfort will win out, although these shine in both categories and have other advanced features. The comfort is there on both with a light design and a soft ear cushion for all-day use.
Inside both the B350 and B450 is a 36 mm speaker to deliver premium audio, along with BlueParrott's industry-leading 98 percent microphone noise cancellation. They both have a Bluetooth range of up to 300 feet and have a customizable BlueParrott button.
The single multifunction button is used for answering and muting calls, and for pairing. They are both rated to operate in temperatures ranging from 14 degrees up to 131 degrees Fahrenheit. The BlueParrott App works with both to customize the BlueParrott button for easy access to features.
There are some differences between them, which is why the prices differ: $169.99 for the B350 and $199.99 for the B450. Before going into the differences, consider them both great choices, with the B450 just having a little edge in some features.
You’ll get 40 hours of talk time with the B350 and an IP54-rated protection against dust and moisture for field work/use. Background noise is controlled by passive noise reduction, and they have a 4.2-ounce weight. It is equipped with Bluetooth 5.3 for multipoint pairing to connect to up to 8 devices, 2 at the same time.
The B450 will give you about 45 hours of use, and a little better weather protection with an IP55 rating. Active noise cancellation keeps your calls crystal clear, and they weigh 4.8 ounces. They also have Bluetooth 5.3 for multi-pairing, and the B450 also gives you 100% voice control.
Looking at both side by side, the B450 seems to have a little more padding. The B350 is described as having a lightweight design with premium cushioned ear cups and T-bar padding. The B450 has a rugged design with premium cushioned ear cups, a headband, and the T-bar pad.
