Blink is today announcing its latest external security camera, the Blink Outdoor 4, which boasts better image quality, improved low-light sensitivity and a wider field of view. For the quality claims, the proof will be in the viewing, but in terms of hard figures, the field of view has increased from 110 degrees to 143 degrees. It says the better image quality both in day, and night, are thanks to the company's latest slice of custom silicon, which offers on-device computer vision. What hasn't changed is the claim of two years' battery life before you'll need to replace the pair of AA batteries nestled inside. It's the second Blink device to offer person detection after its wired floodlight camera, which was announced around this time last year.

Earlier this year TP-Link launched its Tapo line of smart home devices that revolve around budget 2K security cameras, introducing several models ranging from $30 to $60. Now, the company has launched a pricier but more impressive indoor/outdoor 2K night vision security camera, the Tapo C40S2. The new model is battery-powered, weatherproofed and wire-free, offering up to 180 days on a charge in both indoor and outdoor environments. It packs an 850nm IR sensor, along with an f/1.6 aperture lens that allows it to see up to 49 feet in the dark, according to the company. With 2K resolution (2,048 x 1,080) a hair above Full HD, TP-Link promises "pristine images, even in low-light conditions." It also comes with AI features that allow it to distinguish between humans, pets, vehicles and packages, providing notifications when someone steps into the property or user-defined activity zones.
