Devices with Jeweller support

In our world, security has long become not just a desire, but a real need. Homes, offices, warehouses - all these places want to be protected from unforeseen situations, be it theft or fire. And here the Jeweller radio protocol comes onto the scene - a development of the Ajax Systems company, which has already won the hearts of people in more than 120 countries. What makes this protocol so special? Let's figure it out together, step by step.

What is Jeweler?

Jeweller is a wireless protocol that works as an invisible link between all Ajax security system devices: sensors, hub and repeaters. Think of it as a reliable postman delivering important messages from one device to another. It transmits alarms, commands or just checks if everything is OK, and does it quickly and without failures. Jeweller operates at frequencies of 868 or 915 MHz - not as congested as Wi-Fi, which gives it an advantage in signal stability.

This protocol is capable of reaching up to 2000 meters in clear line of sight. This means it works equally well in a cozy apartment, a huge warehouse, or a spacious house with a garden. This makes Jeweller a real helper for those who value reliability.

How does this work in practice?

Imagine: late at night, you’re at home, and suddenly the sensor in the living room detects movement. What happens next? Jeweller instantly – in about 0.15 seconds – transmits a signal to the hub. And the hub notifies you via the app on your phone or notifies the security company. Everything happens so fast that you don’t even have time to blink.

But Jeweller doesn’t just “shout” about a problem—it can listen back. It’s a two-way communication: the hub can send an acknowledgement or command to the sensor, such as to check the status again. If the signal is lost due to noise or interference, Jeweller doesn’t give up—it switches to a different frequency and tries again. And thanks to TDMA technology, each device knows when to “speak” so as not to disturb the others. It’s like a friendly conversation where everyone can hear each other.

Protection you can trust

Security is not just about physical locks, it's also about data protection. Jeweller encrypts all messages using a complex algorithm with a dynamic key. Intercepting or forging a signal is not an easy task, if at all possible. Each sensor undergoes a "who are you" check before starting work, so there will be no strangers in the system.

What if someone tries to jam the signal with a special device? Jeweller will immediately notice this and reorganize to bypass the obstacles. It's like a defender who is always ready to repel an attack, giving you confidence every day.

Why do users choose Jeweller?

Jeweller is not just a set of technical features, but real support for people. Here's what makes it so convenient:

• Flexibility: Connect up to 200 devices to the hub, from sensors to sirens. Want more protection? Just add a few more elements.
• Range: 2000 meters is no joke. The signal will reach even the farthest corner of your plot.
• Durability: The batteries in the sensors last up to 7 years. Forget about frequent replacement.
• Simplicity: everything is set up through the app – no wires or complicated instructions.

These advantages make Jeweller ideal for both a small apartment and a large business. Imagine: you opened a coffee shop, and then a second one - the system easily expands along with your plans.

Are there any pitfalls?

As with everything, Jeweller has its own peculiarities. The signal can weaken due to thick walls or metal structures. In such cases, repeaters come to the rescue, expanding the coverage area. Also, the frequencies 868 or 915 MHz are regulated differently in different countries, but Ajax has already taken care of this by offering adapted versions.

Jeweller – a step into the future of security

The world is changing and threats are becoming more sophisticated. Jeweller proves that technology can keep up with the times, giving people a sense of security. It doesn’t just transmit signals – it keeps you safe, whether at home or at work.

Compared to other protocols, Jeweller wins due to its simplicity and reliability. It is not just a smart technology – it is your ally in the fight against the unpredictable. And if you are looking for a system that will not let you down, Ajax with Jeweller can be the solution. Because security is not a luxury, but something that makes our lives better.
