Do you want your security system to respond instantly and operate longer without replacing batteries?

WOR (Wake-On-Radio) in wireless security systems is a technology that allows radio devices to remain in deep sleep mode and “wake up” only when a specific radio signal is received.

This feature also allows us to “wake up” keyboards, sirens, photo-verification sensors, etc. to activate an audible signal when there is a delay at the entrance/exit and an audible alarm almost instantly.

From now on, WOR (Wake-On-Radio) technology is available in keypads, sirens, and photo-verification sensors.

Previously, before the introduction of WOR technology, the wake-up time in “Armed” mode was about 10 seconds, and in “Disarmed” mode – up to 2 minutes.

Therefore, in U-PROX security systems, the use of WOR improves interactivity and extends the operating time of wireless sensors (e.g., PIR Cam) and executive devices (keyboards) on a single set of batteries by applying an optimal test period (the so-called polling frequency) without significantly reducing it, as was usually done before.

WOR technology makes U-PROX equipment the ideal solution for modern security systems, providing a balance between reliability, convenience, and cost-effectiveness.

Add U-PROX security systems with WOR to your projects, and your customers will feel the difference from day one.

Want to be on trend with modern secure identification technologies in access control systems?

The multi-standard U-PROX Desktop reader with USB interface now supports Mifare DesFire secure identifier technology – a family of 13.56 MHz contactless chips compatible with the ISO/IEC 14443 A standard.

At the request of our foreign customers and foreign companies currently operating in Ukraine, U-PROX engineers have made it possible to use DesFire technology for our ACS.

The new firmware for the U-PROX Desktop USB reader allows the issuance of encrypted DesFire identifiers/cards of all generations of this technology currently available: EV1, EV2, EV3. Desktop readers by U-PROX are also capable of reading these cards in encrypted form.

So, what is DesFire (Data Encryption Standard Files with Random Access) technology?

It was created in response to the hacking of Mifare Classic cards, which date back to 1994, even before the advent of Mifare Plus in 2008.

In 2002-2004, DesFire EV1 appeared, and the evolution continued with improvements in security, speed, number of supported files and applications, memory, compatibility with mobile platforms, and IoT support. In 2016, EV2 appeared, and in 2020, EV3.

Where is DesFire used?

Many transport and payment systems run on DesFire technology, making these cards attractive for use as identifiers in access control systems alongside other “projects” recorded on them.
