Protecting your home from a burglar has never been smarter, but with so many advanced tech options hitting the security market, finding the right starting point can feel overwhelming. We have recently expanded our catalogue to include the highly acclaimed Ajax Systems Baseline wireless intruder alarm system. While these sleek, grade-2 certified devices offer top-tier protection, knowing exactly which sensors, hubs, and sirens fit your specific property layout can be difficult to navigate.
This guide will break down exactly how to choose the right components for your property, ensuring you don't overspend or buy equipment that doesn’t contribute to your safety. To make your decision even simpler, we have included a full Ajax Systems summary at the end of this article to help you finalise your security setup.

Saving Money with Ajax Systems’ Kits
When building a home alarm setup from scratch, it is tempting to go through the catalogue and hand-pick every individual sensor, keypad, and siren one by one. However, piecing an entire security system together is almost never the most cost-effective route. It usually also includes picking out a lot of products that sound good but don’t contribute any additional benefits to preventing a burglar. If you want to maximise your budget, starting with a pre-configured bundle is the smarter financial move. Manufacturers package these core bundles at a discounted rate, meaning you save a noticeable amount of money compared to buying the exact same items individually.
The most efficient method for designing your setup follows a simple three-step formula:
Map Your Property Specifications: Walk through your home and identify your vulnerable entry points. Note down exactly how many doors, ground-floor windows, and open living spaces require coverage. You’re less likely to have any security vulnerabilities if you plan your detectors out first.
Find Your Core Bundle: Browse the available pre-packaged options to find the one that checks off the highest percentage of your list. Every standard bundle automatically includes an essential hub, which acts as the brain of the ecosystem.
Expand & Personalise: Once you have your foundational bundle selected, simply add any remaining specialised sensors or extra sirens to your cart individually.
By using this hybrid approach, you protect your home against a potential burglar while keeping your upfront investment as low as possible. You get a fully customised security system without paying standalone retail prices for the core essentials.

Finding the Right Hub Jeweller for You
Think of the hub as the CPU of your entire setup. Every system needs one, no exceptions. It acts as the central control unit for any modern intruder system, constantly managing the wireless data traffic from your perimeter sensors. If a burglar activates a window contact or a motion detector, the hub processes that signal straight away and pushes an emergency alert directly to your mobile phone, keeping your home security tightly coordinated and responsive. Because different properties have unique coverage and network demands, we have picked out two distinct baseline hub configurations (plus the ones that come in their premade kits). Choosing the right one depends entirely on the size of your home and how you prefer to connect to the internet.
1. Ajax Hub 4G: Reliable Entry-Level Protection
The Hub 4G is an excellent basic wireless hub that brings updated cellular flexibility to smaller or mid-sized properties. It is ideal for warding off burglars in flats, homes, or standalone outbuildings where a direct wired internet connection is readily available alongside mobile backup for constant security.
Network Connectivity: Built-in support for 2G, 3G, and 4G cellular networks, alongside a physical Ethernet port.
Device Capacity: Links up to 100 individual wireless devices and accommodates 1 radio signal range extender.
User Profiles & Zoning: Manages up to 50 unique users and handles 9 separate system zones for different parts of the property.
Smart Automation: Allows you to configure up to 5 automated scenarios, such as scheduled arming profiles.
2. Ajax Hub 2 Plus: High-Capacity Smart Flexibility
For larger homes or users looking to make the most of the advanced burglar deterrents offered by Ajax Systems, the Hub 2 Plus stands out as the best choice as a baseline range hub. It maximises your network options by introducing native Wi-Fi connectivity and delivers a major step up in security features.
Network Connectivity: Quad-network capabilities featuring 2G, 3G, and 4G cellular support, an Ethernet port, and built-in Wi-Fi.
Device Capacity: Scales up to 200 connected devices and supports up to 5 range extenders to blanket large properties with seamless coverage.
User Profiles & Zoning: Accommodates up to 200 independent users and provides 25 distinct system zones for intricate needs.
Smart Automation: Powers up to 64 complex scenarios, letting you build deep integrations like turning off specific smart plugs when the system arms.
Choosing the Right Siren for You
A silent notification sent to your smartphone is highly informative, but it does little to stop a burglar who has already triggered your detector. To truly safeguard your property, almost all security systems rely on at least one high-decibel audible sounder to instantly shock and scare off a potential intruder. Integrating these audio devices into your setup provides an immediate intimidating blast, upgrading your home intruder alarms from a passive notification system into an active, high-volume deterrent that alerts your immediate neighbours and family.
1. Ajax HomeSiren: Focused Internal Alerts
The HomeSiren is a compact, minimalist wireless indoor sounder designed to disorient intruders and instantly alert occupants inside the house. If you live in a property like a flat that has no external areas a home siren would be perfect for you.
2. Ajax StreetSiren: High-Visibility Security
The StreetSiren is a rugged, weather-resistant outdoor audio and visual unit featuring a built-in LED frame. It acts as your home's primary external line of defence. When this goes off it will alert you, your neighbours and scare any burglar trying to get in.
Identifying Your Detectors
An alarm setup is only as reliable as its sensors. Ajax Systems’ Baseline range features multiple options, designed to spot an intruder before they get to your property. By placing the right device in the right location, you build layers of defence that filter out false alarms while maintaining absolute vigilance. We’ve hand picked the most versatile and useful detectors for you to choose from to give your security structure:
This outdoor sensor monitors external areas like gardens, driveways, and patios, intelligently identifying only human movement before a burglar ever reaches your walls. Choose this if you want an early warning system to stop unwanted people approaching your perimeter. It is perfect for securing private land, detached garages, or dark side passages.
2. Ajax MotionProtect Plus (Indoor)
Designed for interior spaces, this advanced motion detector combines a passive infrared (PIR) sensor with an additional microwave sensor to scan rooms and hallways. It is highly recommended for private areas or rooms that should only be used during operating hours.
It utilises a sensitive electret microphone to listen specifically for the low-frequency thud and high-frequency shatter of breaking glass panes up to 9 meters away. Position these security devices in rooms with large expanses of glazing or highly accessible ground-floor windows. It ensures that if a burglar smashes a window pane without actually opening the frame, your system still catches them instantly.
4. Ajax DoorProtect Plus
This smart contact monitors doors being forced open. The "Plus" designation means it features a built-in accelerometer that handles shock and vibration detection too. You will want these primarily on your main entry and exit ways. Because it senses impacts and tilts, it can trigger an alarm the exact moment someone attempts to kick or crowbar the door, long before the frame actually separates.
How to Arm/ Disarm Your System
While managing your security system via a smartphone app is incredibly convenient, day-to-day use often calls for a physical touchpoint. Whether you want a quick backup for when your phone battery dies, or an easy option for family, Ajax Systems’ provide robust physical methods for control. Choosing the right hardware ensures your property maintains a seamless shield, streamlining your daily burglar defence system without complicating your entry and exit.
This miniature, lightweight remote control fob allows you to fully arm or disarm your hardware entirely on the move. As seen in the design, it features a minimalist four-button layout with an integrated central LED indicator to visually confirm that your security was armed/ disarmed successfully. It is the ultimate choice for your daily keyring. It lets you secure your home or disarm the perimeter as you pull into the driveway, completely eliminating the need to rush inside to a wall panel before an exit delay expires. It also features a built-in panic button for emergency triggering like spotting a burglar before the detectors do.
This touch-sensitive wall panel beautifully blends advanced technology with a traditional approach. It features contactless authentication via encrypted cards or tags, absolute protection against spoofing or password guessing, and a dedicated duress code function. This is ideal for mounting next to a front door or side entrance. It is particularly valuable for properties where multiple people need to access the security system; they can simply tap the tag or type in a code to disarm. Furthermore, if an intruder ever forces you to turn off the alarm, typing in the secret duress code simulates a normal disarm on the screen while silently informing your chosen monitoring station of a burglar.
This premium console uses the official Ajax app interface on a physical arming and disarming device. Featuring a sharp, responsive display, it allows you to learn one interface for both app and physical control. This is the perfect central command panel for larger properties or families who want complete visual clarity. Because it mirrors the mobile application, anyone with the login password can walk up to the screen and instantly check the status of specific system groups, view security event logs, or manage smart home automation scenarios with a simple swipe.
