DefenDoor lets you recreate the pizza delivery scene from Home Alone, wirelessly

Add as a preferred source on Google

There’s no shortage of smart doorbells or Internet-connected, camera-equipped security devices, especially on crowd-funding sites. The nice thing about DefenDoor is that it’s both.

Billing itself as cross between a butler, a concierge, and a security guard (now we’re picturing a mix of Alfred, Tim Curry in Home Alone 2, and the doorman from that Seinfeld episode), the security system uses a video camera, as well as motion and vibration detectors, to send alerts to your smartphone about what’s going on inside your home.

The DefenDoor attaches to your front door. When the motion detector senses movement, the camera turns on and takes a picture of the visitor, which is then sent to your smartphone. Depending on who’s at the door, you can talk to them via one-way video, ignore them, or send a pre-recorded message. Ours would say, “I’m gonna give you to the count of 10, to get your ugly, yella, no-good keister off my property, before I pump your guts full of lead.”

Wireless and waterproof, the device can be used inside or out. It can be paired with up to five sensors, though the camera has to be pointed at the sensors if you want to get video footage of what’s causing a disturbance. The sensors and camera also need to be within 30 feet of each other, so you’d want a few of them to cover a whole house.

Like similar devices, the DefenDoor uses beacon technology that can alert you when your latchkey kid is home or start monitoring when your smartphone is out of range.

The system has a few features that set it apart from similar devices. The camera offers a 150-degree lens, better than Netgear’s 120-degree one but not as good as Piper’s 180 one. However, the 30-second video clip it records when the motion or vibration sensors kick in is 10 seconds longer than Piper’s.

Just the camera alone costs $149. With the special Kickstarter deal on now, a full package, which comes with five sensors, is going for $192, though it’s limited to 100 backers. That’s pretty well in-line with other smart security and doorbell devices that got their start on crowd-funding sites. The device should be ready to ship in July 2015, provided everything goes according to plan.

We have to say though, this would’ve been pretty useful in catching the Wet Bandits.

iRobot’s new Roomba concept uses a piggybacking sidekick to reach tight spaces

Robot vacuums have long forced buyers to choose between cleaning power and clearance. Heavy-duty wet-dry models pack enough scrubbing force to tackle stubborn, sticky messes, but their bulky frames often can't squeeze under low furniture. Slim robot vacuums can glide beneath sofas and beds, but they typically lack the muscle to do much more than sweep up light dust. iRobot's new Roomba Duo concept, unveiled at IFA 2026 in Berlin, aims to solve this problem with an unconventional approach that involves deploying two specialized robots to work as a team.

The IFA 2026 Publisher Award Winners Bring Fresh Ideas to Everyday Tech
From Smarter Entry to Screen-Free Wellness, These IFA 2026 Winners Do Things Differently
IFA 2026 Publisher Awards

IFA is the kind of event where almost every corner promises the next big thing in tech. Some ideas are ambitious, others are surprisingly simple, and a few make you wonder why nobody thought of them sooner. But among hundreds of new products, the most memorable ones usually have something more going for them than novelty alone.

This year’s IFA Publisher Award winners are a good example. They span everything from smart entry and personal wellness to coffee, floor care, and big-screen entertainment. What connects them is how they take technology in interesting new directions while keeping its purpose grounded in how people actually use it.

Apple could soon offer home security and monitoring service as it plans security camera foray
Apple may use AI, facial detection, and its existing device ecosystem to build a more private home security setup

It looks like Apple has plans to make a splashy entrance in the smart home and security segment. Back in 2024, industry analyst Ming-Chi Kuo wrote that Apple was prepping its foray into the smart home IP camera market. A year later, Bloomberg reported that Apple had started work on a home security camera code-named J450. Now, the outlet reports that the company will also launch a home security service to go with its camera, something all major players in the domain currently offer. 

“Apple is planning a privacy-centric home security camera and automation device that will use AI to monitor the surrounding environment instead of actual video footage. It will tap into a new home security and monitoring service,” says a new report by Bloomberg.
