Roughly five inches tall and four inches wide, the all-black Keen resembles a small Russian nesting doll, thanks to its rounded top with speaker grilles on each side of the head that look a bit like ears. The included PIR motion sensor uses infrared detection to eliminate false alerts triggered by blowing leaves or tree limbs. Under normal conditions, a set of these batteries can power Keen for up to six months in standby mode. There’s no AC power option, so you’ll want to keep a backup supply of these less common batteries on hand. Reolink Keen ($130 on Amazon) is a security camera powered entirely by four included CR123A batteries, powerful 3.0-volt cells typically reserved for photo accessories. The folks at Reolink have introduced the world’s first battery-powered security camera, offering the freedom to move it anywhere around the home. After all, wires can be severed or simply unplugged, disabling a camera before it ever has a chance to catch a glimpse of potential intruders.Īlthough Wi-Fi allows cameras to have one less tether, manufacturers mostly disregard the real elephant in the room-until now.
I’ve reviewed several home security cameras over the years, and always grapple with where to mount them close to a required electrical outlet.
