Truly wireless power has been a long time coming, but it’s finally here at MWC 2023. The ARCHOS Cota Wireless Power Security Camera, powered by wireless technology from Ossia, doesn’t require wires, not even for power, to help keep your home secure. Ossia claims it’s the first commercially available wirelessly-powered product, and we saw a demo of it in action.

These wireless indoor security cameras can be placed anywhere within 30 feet (9m) of a base transmitter that supplies power over the air. The technology isn’t super powerful in terms of wattage; it only supplies about 2W of power at a range of two meters and mere milliwatts at up to 10 meters. However, its application flexibility, such as placing security cameras in otherwise impossible-to-wire places, makes the technology so useful.

Ossia notes that the security cameras don’t have to have line of sight of each other. The base can also transmit power through glass, sheet, rock, and wood, but not bricks or cement. Ossia’s technology works in the common 2.4GHz and 5GHz wireless bands, which your home Wi-Fi uses, which has helped it secure certification for use in 66 countries.

You might have seen the ARCHOS Cota Wireless Power Security Camera earlier in the year at CES 2023, but the company is now listing the security camera for pre-order. There are two bundles on offer; the first provides a transmitter and three cameras, while the second doubles up the package for larger commercial spaces.

Ossia’s Cota wireless power technology isn’t limited to security cameras. In fact, the camera is enabled by the Corta Universal base, which contains the antennas, battery, and USB plug that allow it to power virtually any low-powered gadgets. The brand also had a few other prototypes to showcase at MWC, including an “everlasting” battery that charges over the air. For smartphones, a USB-C or Magsafe case could also provide constant power without the need for wires. That said, the 2W power limit…

Origin Of Wireless Security: The Marconi Radio Hack Of 1903

/in


The place is the historic lecture theater of the Royal Institution in London. The date is the 4th of June 1903, and the inventor, Guglielmo Marconi, is about to demonstrate his new wireless system, which he claims can securely send messages over a long distance, without interference by tuning the signal.

The inventor himself was over 300 miles away in Cornwall, preparing to send the messages to his colleague Professor Fleming in the theater. Towards the end of Professor Flemings lecture, the receiver sparks into life, and the morse code printer started printing out one word repeatedly: “Rats”. It then spelled out an insulting limerick: “There was a young man from Italy, who diddled the public quite prettily”. Marconi’s supposedly secure system had been hacked.

The person behind this hack was Nevil Maskelyne, an inventor, magician, and general troublemaker who was a long-time rival of Marconi. He was the manager of a rival wireless company and had been involved in a number of disputes with Marconi over the patents that covered wireless telegraphy systems. He decided that the most effective way to show that Marconi’s claims were hollow was a practical demonstration.

In the trade journal The Electrician (the Hackaday of its time) he detailed how he hacked the system. One of the fundamental claims of Marconi was that because his system used a tuned signal, other signals would not interfere unless they were tuned to the same frequency. This, however, had not been proven to the satisfaction of Maskelyne, and he didn’t accept that the system was really secure. So, he set out to demonstrate this. But how could you prove this? In his account in The Electrican, he wrote that:

“When, however, it was pointed out to me that the practical demonstrations accompanying the lecture rendered independent tests possible, I at once grasped the fact that the opportunity was too good to be missed…The only hope, then, was to interpolate messages calculated to anger and “draw” somebody at the receiving end. If that could be done, there would be proof positive.”

His plan involved setting up a transmitter not far…
