Ajax versus Hills Alarm: The Ultimate Security Showdown
A comprehensive technical analysis of the wireless revolution vs. the hybrid powerhouse.
The security industry is at a pivotal moment. While the line between “smart home gadget” and “professional security system” has blurred, the fundamental divide remains: Wireless Innovation versus Hardwired Reliability.
When comparing Ajax vs Hills Alarm, the decision is critical for Australian property owners. On one hand, you have Ajax Systems, the European disruptor redefining user experience. On the other, Hills Alarm (Reliance) stands as the established veteran, known for its bulletproof durability.
<!-- Industry Insight -->
“Modern security isn’t just about alarms; it’s about ecosystem. Ajax sells a lifestyle of safety, while Hills sells the infrastructure of security.”
This article dissects both systems. We analyze their architecture, encryption standards, and real-world usability. Consequently, you can make the only decision that matters: Which system will you trust with your safety?
Ajax Systems: The Wireless Revolution
Ajax has not just entered the market; they have stormed it. Their proprietary Jeweller radio protocol has become the gold standard for wireless stability. Unlike traditional Wi-Fi based systems that are prone to jamming, Jeweller operates on a secure radio frequency. Therefore, it can transmit data up to 2,000 meters in open space.
Key Technical Advantages
- Jeweller Protocol: Operates up to 2,000 meters. It is encrypted, energy-efficient, and resistant to jamming. Furthermore, it uses a rolling code to prevent signal interception.
- Smart Ecosystem: Seamless integration with leak detectors and fire safety. For instance, the FireProtect 2 and WaterStop devices communicate directly with the Hub.
- User Experience: An app interface that rivals Apple in fluidity. The Ajax app provides real-time system status and instant notifications (SwiftAlerts).
The Power of Visual Verification
One of Ajax’s standout features is the MotionCam detector. These devices don’t just detect motion; they capture photos to verify the alarm. This “Photo on Demand” technology reduces false alarms significantly. If the alarm goes off, you know exactly why within seconds.
Design That Doesn’t Look Like Security
Most security sensors are ugly beige boxes. However, Ajax changed the narrative with sleek, minimalist designs. They are available in black or white, blending seamlessly into modern decor.
Hills Alarm (Reliance): The Hybrid Powerhouse
If Ajax is the modern sports car, Hills Reliance is the tank. It may not have the flashiest dashboard, but it is built to survive anything. The Hills Reliance XRPro series represents the pinnacle of hybrid security. It bridges the gap between traditional hardwired reliability and modern connectivity.
Key Technical Advantages
- Hybrid Architecture: The XRPro series blends wired zones with wireless expansion. This allows you to utilize existing cabling in older homes while adding wireless sensors to new extensions.
- Scalability: Supporting up to 176 zones, it is the default choice for large estates. Additionally, it can manage up to 8 separate partitions, making it ideal for multi-tenant properties.
- Zero Latency: Hardwired connections offer instant response times. There is zero risk of radio interference or battery failure.
NBN Compatibility and The ComNav Solution
With the NBN rollout complete, older dialer-based alarms have become obsolete. However, Hills addressed this with the ComNav and UltraSync modules. These IP-based solutions allow the Reliance system to communicate securely over the internet. This ensures your monitoring is future-proof.
Why “Old School” Still Matters
In a world of constant firmware updates, there is something to be said for a system that just works. Hills Reliance panels are renowned for their longevity. It is not uncommon to find Hills systems installed 15 years ago still operating perfectly. For commercial applications, this track record is invaluable.

The Verdict: Which System Wins?
The “best” system depends entirely on your property’s infrastructure and your lifestyle priorities.
Choose Ajax Systems If:
- You live in a finished home or rental where running cables is impossible.
- You prioritize a premium mobile app experience and smart home automation.
- You want visual verification (MotionCam) without installing a separate CCTV system.
- You appreciate modern, minimalist design.
Choose Hills Reliance If:
- You are building a new home (pre-wiring is always superior to wireless).
- You have a large commercial property requiring over 100 zones.
- You want a “set and forget” system with a proven 20-year lifespan.
- You prefer a traditional wall-mounted keypad interface.

Frequently Asked Questions
Does Ajax work without Wi-Fi?
Yes. The Ajax Hub uses Ethernet as a primary channel and has a SIM card slot (2G/4G) for cellular backup. If your Wi-Fi goes down, the system switches to mobile data instantly.
Can I install Hills Reliance myself?
It is not recommended. Hills systems require complex programming and hardwiring. Incorrect installation can lead to false alarms or system failure. Always use a licensed security technician.
What happens if the power goes out?
Both systems have backup batteries. The Hills Reliance typically uses a large 12V 7Ah battery that lasts 24+ hours. Ajax Hubs have a built-in battery that lasts up to 16 hours.
