Swann DVR4-2600: monitor four live security cams via smartphone

Add as a preferred source on Google

Not everyone is in the market for video surveillance systems, but folks who are know that if the video gear proves to be handle, it’s usually after a break-in or other crime has been committed: most systems are merely passive recorders of what the cameras see, and don’t enable owners to keep tabs on things while they’re away. Not so with the new Swann DVR4-2600 video surveillance system: it not only includes support for up to four cameras and comes with a 500 GB hard drive pre-installed, it can offer live remote monitoring from 3G smartphones, including Symbian, Windows Mobile, Android, BlackBerry, and (yes) iOS devices.

“This is a flagship product for Swann in 2011” said Swann’s VP for global marketing Jeremy Stewart, in a statement. “It brings together video surveillance with phone connectivity and convenience as never before.”

The DVR4-2600 supports viewing and recording by up to four cameras, which record at up to 704 by 480 (NTSC) or 704 by 576 (PAL) and automatically stamp video with the time and date. The 500 GB hard drive should be enough for about 30 days of continuous video, but users can save on hard drive space by using motion detection recording that only records video when the system detects changes in the camera views. Video can be transfered to USB drives for archiving and storage, and the system can be connected to a TV or PC monitor for live viewing: users can set up all four cameras on-screen at once. The system comes with a remote control, and Swann’s PRO-580 cameras sport a 62° viewing angle, infrared LEDs for night vision shooting in dark spaces, and can handle cable lengths up to 60 feet.

However, the breakthrough feature on the DVR4-2600 is smartphone monitoring: users just need to installed the three SwannView app available from Swann directly (or, for iOS users, from the iTunes App Store): once the app is running, users just need to enter their DVR’s IP address, port, and login information, and they’ll be able to view camera feeds in real time.

The DVR4-2600 with four PRO-580 cameras has a suggested price of $449 and will be available in March; a version will also be available without cameras, and folks with more extensive monitoring needs can check out 8- and 16-camera variations.

AI can’t tell if you’re gay or straight, but it thinks it knows what both look like
AI knows it shouldn't judge a face, but apparently, drawing one is a different story.

We've all been told not to judge a book by its cover, and you'd think AI would follow that rule, too. Ask an AI chatbot to guess someone's sexual orientation just by looking at their face, and it'll likely tell you that there's no reliable way to know. But what happens when you ask that same model to change someone's appearance to match a particular sexual orientation? Well, that's where things get uncomfortable.

A new study, accepted for presentation at the 2026 Conference on Empirical Methods in Natural Language Processing, found that AI models from OpenAI and Google can be inconsistent when handling sensitive personal characteristics. They might refuse to make assumptions about someone based on their appearance, but when asked to generate those same assumptions visually, the results tell a very different story.

AI is a useful tool for handling many tasks in private as well as professional settings, but medical advice, especially diagnosis, is one area where I generally draw the line. General-purpose chatbots tend to sound confident and convincing while giving medical advice, even when they are wrong, as studies have previously found.

That being said, Google's new research points to a much more convincing use for AI in healthcare. Its Articulate Medical Intelligence Explorer chatbot, or AMIE for short, could help prepare both sides before the appointment even begins.

Relaxation music had one job in this pain study, and favorite songs did it better
Patients who chose their music reported less pain after an IV insertion
Book, Publication, Indoors

Patients’ favorite songs helped ease pain after an IV insertion in a new study, while music specifically chosen for relaxation didn’t show a significant benefit. The soothing soundtrack could apparently use a second opinion.

Researchers at University Hospital Zürich studied 204 patients receiving an IV cannula before an MRI scan. Those listening to their chosen music reported less pain 30 seconds and two minutes after insertion. Across the full sample, the clearest relief came after the needle went in.
