Arm, disarm and create custom automation scenes from the Ajax Home or Security app — compatible with iOS and Android with role-based user access.
CCTV Integration
Pair your Ajax perimeter sensors with Reolink or HiLook cameras to trigger automatic recording when a sensor fires — full ecosystem, one alert.
Pet-Friendly Mode
Smart dual-tech detection differentiates between a 30kg dog running past and a human intruder approaching. Zero false alarms at 3 am.
Smart Intrusion Detection Before Entry
Traditional alarms are designed to react — they wait for a contact sensor to open or a PIR to trigger inside. Ajax Perimeter Protection does the opposite: it detects movement in your outdoor zones minutes before any door or window is touched, giving you time to respond, not just record.
Detection Distance vs Traditional
A standard PIR triggers when someone is already inside the room. Ajax MotionProtect Outdoor detects movement up to 15 metres away across open ground — dual PIR + microwave technology that virtually eliminates false triggers from wind, animals and passing traffic. Traditional alarms: 0m of warning. Ajax: up to 15m.
Response Timeline
When an outdoor Ajax sensor fires, it communicates with the hub in under 0.15 seconds. The hub evaluates the signal, cross-checks neighbouring sensors, and pushes a push notification with a photo (MotionCam) to your phone in under 9 seconds. A traditional alarm that dials a monitoring centre averages 45–90 seconds response time.
False Alarm Rejection
Traditional PIR sensors fire on pets, air-con drafts and insects on the lens. Ajax Outdoor sensors use dual-channel PIR with digital signal processing — they compare the infrared heat reading against microwave Doppler data, and only raise an alarm when both channels agree. The result: near-zero false alarm rate reported by SIPKO installations across Melbourne.
Tamper & Jam Proof
Professional intruders know how to defeat traditional alarms — cut the phone line, spray paint the siren, or jam the GSM signal. Ajax counters this with frequency-hopping Jeweller radio that detects jamming attempts and alerts you immediately, plus a tamper sensor on every device that fires the moment a cover is removed.
🔍 Early Detection vs. Traditional Alarms
The difference between the two is not a feature upgrade — it is a fundamentally different philosophy about where security begins. Traditional systems wait for a breach. Ajax Perimeter starts protecting three layers before anyone reaches your front door.
Where Detection Happens
A traditional alarm system defines its boundary at your physical structure — the door frame, a window contact, or an interior PIR installed in a hallway. By the time any of those sensors activate, an intruder has already committed to entry. They are physically inside or in the act of forcing entry. Your sensor fires, a siren sounds, and if you are lucky a monitoring centre calls in 90 seconds — by which time the threat has already escalated.
Ajax MotionProtect Outdoor and DualCurtain sensors operate in your garden, driveway, fencing perimeter and boundary walls. Detection begins 5–15 metres from your building. You receive a photo alert on your phone while the intruder is still assessing your property — before they have committed an act, not after.
Ajax Perimeter: up to 15m
How the Sensor Intelligence Works
Standard PIR sensors rely on a single detection channel — passive infrared. Any movement that generates a heat signature triggers the sensor, including pets, moths, sunlight through a window and even air-conditioning vents. This is why false alarms are so common with traditional systems, leading most owners to disable them.
Ajax outdoor sensors use two independent detection channels operating simultaneously: passive infrared (PIR) measures body heat, and a microwave Doppler channel measures movement velocity and mass. The alarm fires only when both channels confirm the same event at the same time. The digital signal processing engine filters out noise, vibration, insects and animals below 80cm. The result is a sensor that distinguishes a 75kg adult from a labrador retriever — without you having to configure anything.
Ajax: dual PIR + microwave confirmation
The SIPKO Installation Advantage
Most perimeter security failures happen not because the sensor is wrong, but because the installer placed it wrong. Detection zones that overlap fences, trees, or public pathways will generate constant false positives. Zones that fail to cover access paths leave blind spots an experienced intruder will find within minutes.
SIPKO Security conducts a physical site assessment before every installation. We map detection zones against your property’s actual entry vectors — gates, side passages, carport access, and any terrain features that create shadow zones. Every Ajax sensor is then aimed, tested, and verified against a live walk-test before we close out the job. You receive a documented placement map and a 12-month re-assessment option as standard.
Live walk-test on every install

- Anti-masking + tamper + jamming detection — three layers of sabotage resistance built in
- Up to 15m range, 90° coverage — covers driveways, gardens and side passages in one unit
- 5-year battery life — no annual maintenance, no rewiring, no electrician visits
- Proven in real Melbourne installations — specified by SIPKO for residential and commercial perimeters
Door & Window Protection with Ajax DoorProtect
Perimeter sensors stop threats in the yard — but a complete system also covers what happens the moment someone touches a door or window. Ajax DoorProtect sensors turn every entry point in your Melbourne property into an instant-alert trigger, monitoring not just whether something opens, but whether it’s been forced, struck or tampered with.
Magnetic Reed Switch Detection
Ajax DoorProtect uses a precision magnetic reed switch — when the door or window opens, the magnetic field between sensor and magnet breaks and the device fires an alert within 0.15 seconds. There are no moving parts, no mechanical wear, and no reset required after each trigger. The sensor monitors continuously 24/7 regardless of whether the alarm is armed, feeding state data to the hub in real time.
No moving parts
24/7 monitoring
Shock & Tilt Detection
The DoorProtect Plus variant adds a built-in accelerometer and shock sensor. This detects attempts to force a door without opening it — glass breaking adjacent to a lock, a crowbar strike against a frame, or a window being lifted in its track. The shock threshold is configurable, so high-traffic commercial doors won’t trigger from normal closing impact while still detecting deliberate forced entry attempts.
Adjustable threshold
Glass break detection
Instant Smartphone Alerts
The moment a DoorProtect sensor triggers, the Ajax hub processes the event and pushes a real-time push notification to your phone via the Ajax Security or Ajax Home app. The alert includes the exact sensor name (e.g. “Front Door Opened”), the time stamp, and — if paired with MotionCam — a verification photo. You know within seconds what opened, where, and when, before deciding whether to call police or investigate yourself.
Photo verification
iOS & Android
Jeweller Wireless — 1,700m Radio Range
Every DoorProtect sensor communicates over Ajax’s Jeweller proprietary radio protocol, operating at 868 MHz with frequency hopping to defeat interference and jamming. The signal travels up to 1,700m in open space, with reliable penetration through walls, floors and steel frames typical of Melbourne’s brick-veneer and double-brick homes. Battery life reaches up to 7 years — no wiring, no conduit, no sparky required.
Up to 7yr battery
No wiring needed
Tamper & Anti-Removal Protection
Professional intruders target sensors first. DoorProtect includes a physical tamper switch on the rear — if anyone removes the sensor from its mount or tries to open its case, the hub receives an immediate tamper alert classified separately from intrusion alarms. Combined with AES-128 encrypted Jeweller communication, the sensor cannot be silenced by signal blocking, battery removal or physical interference without the system knowing immediately.
AES-128 encrypted
Jam detection
Smart Home & Automation Integration
DoorProtect works within the Ajax automation ecosystem — its open/close state can trigger lighting scenes, camera recordings, siren activation or user notifications through the Ajax app or third-party platforms like Apple HomeKit. Set the front door opening to simultaneously turn on entrance lights, start CCTV recording and disarm the alarm — all automatically. Individual user access schedules mean you choose who gets notified and when.

CCTV trigger
Glass Break Detection with Ajax GlassProtect
Doors and motion sensors only cover what they can see. A trained intruder who knows how to move slowly won’t trigger an outdoor PIR — but they can’t break glass silently. Ajax GlassProtect listens for the exact acoustic signature of breaking glass and fires an alert before anyone has climbed through the opening.
Acoustic Pattern Recognition
Ajax GlassProtect doesn’t react to loud sounds — it uses a two-stage acoustic analysis system. The microphone listens first for the low-frequency thud of impact, then immediately checks for the high-frequency tinkling signature of shattering glass. Both signals must occur in the correct sequence within milliseconds of each other before an alarm fires. A slammed door, dropped object or thunderclap will not trigger it — only the actual acoustic fingerprint of breaking glass will.
Impact + shatter detection
False-alarm resistant
Single Sensor Covers Multiple Windows
One Ajax GlassProtect sensor placed correctly in a room can cover all glazing within a 9-metre detection radius — that includes a front bay window, two sidelights and an adjacent patio door simultaneously. In open-plan Melbourne homes where a single living area has continuous glazing across multiple orientations, this eliminates the need to install individual contact sensors on every pane — dramatically reducing cost while maintaining full coverage.
Multi-window coverage
Open-plan ready
Prevents Silent Entry — Closes the Gap
The logic of layered security is that each layer catches what the previous missed. Outdoor PIR sensors catch movement in the yard. DoorProtect catches door/window opening. GlassProtect catches the one attack vector neither of those can — breaking glass without opening anything. A smash-and-grab through a kitchen window, a sliding door panel punched out, or a louvred slat carefully removed all produce glass fracture sounds. GlassProtect converts that sound into an immediate alert to hub and phone within 0.15 seconds.
0.15s alert
Layer 3 defence
Glass Types & Sensitivity
Ajax GlassProtect is calibrated to detect tempered, laminated and standard float glass — the three types used in Melbourne residential and commercial glazing. Sensitivity is adjustable across three levels: low (large commercial spaces with background noise), medium (standard residential), and high (small rooms or thin glazing). The sensor operates on Jeweller radio with 7-year battery life and tamper protection, requiring no mains power and no cables.
Laminated glass
3 sensitivity levels
7yr battery
🧱 Where GlassProtect Fits in a Complete Ajax System
A professionally designed Ajax perimeter system uses three detection layers, each covering a different attack scenario. GlassProtect is Layer 3 — the last line of defence before an intruder reaches the interior of your property.
| Layer | Device | What It Catches | When It Fires |
|---|---|---|---|
| Layer 1 — Perimeter | MotionProtect Outdoor | Human movement in yard or garden | 5–15m from building |
| Layer 2 — Entry Points | DoorProtect / DoorProtect Plus | Door or window opened / forced | At the frame |
| Layer 3 — Glass | GlassProtect | Glass broken without opening | Acoustic pattern <0.15s |
| Layer 4 — Interior | MotionProtect (indoor) | Movement inside rooms | Inside the property |
👉 SIPKO Security installs all four layers as a coordinated system — each calibrated against your specific floor plan, glazing type and risk profile.
Visual proof sent directly to your phone
Ajax MotionCam Outdoor (Jeweller)
This is your first line of defence. It detects movement before someone reaches your building and sends an encrypted photo series to the Ajax app within 9 seconds. It eliminates the “guessing game” of traditional alarms by letting you verify the threat instantly in Melbourne’s variable conditions.

- Discreet, low-profile body available in Black or White to match your joinery
- 2-year manufacturer’s warranty with local SIPKO Melbourne support
Stay Sound Asleep with Ajax Night Mode
Traditional alarms are often turned off while you’re home because they restrict movement. Ajax “Night Mode” changes everything — arm your property boundary sensors while leaving your interior zones completely disarmed.
Active Outdoor Boundary
Arm only your outdoor MotionProtect sensors and door contacts. This creates an invisible barrier at your garden fence or driveway, detecting intruders long before they reach your building structure.
- Detects threats at the property line
- Siren sounds before entry is attempted
Complete Internal Freedom
Move freely from the bedroom to the kitchen or bathroom without fear of tripping a PIR. Interior motion detectors are automatically bypassed, making it perfect for homes with pets or light sleepers.
- No restrictions on internal movement
- Internal sensors remain in stand-by
One-Tap Activation
Set a schedule or arm manually with one tap on the Ajax app or a dedicated SpaceControl keyfob by your bed. It’s the ultimate peace-of-mind setup for both residential homes and commercial sites.
- Simple bed-side arming
- Scheduled auto-arming at 11:00 PM
Stop Intruders with High-Intensity Deterrence
Detection is only half the battle. Our Ajax systems aren’t just designed to notify you — they are built to create a high-pressure, disorienting environment that forces intruders to leave immediately.
113dB Outdoor Sirens
The Ajax StreetSiren creates a wall of sound that can be heard up to 150 metres away. At 113dB, the noise level is equivalent to a rock concert or a low-flying jet — physically painful and impossible to ignore.
- Immediate neighbourhood awareness
- Forces intruder panic & withdrawal
Volume: 113 Decibels
Synchronized Strobe Blasts
Visual deterrence is a critical layer of psychological defense. Integrated high-intensity LEDs flash in synchronized bursts the moment an alarm is triggered, instantly revealing an intruder’s position to every neighbor.
- Visual guidance for emergency services
- Disorients intruder night vision
Intensity: High-Vis LED Array
Psychological Shock Effect
The deterrent effect of a professional siren is near-instant. Most opportunists will flee the property within 15 seconds of the initial siren blast, knowing that human eyes and police response are already in motion.
- Stops theft before goods are reached
- Minimizes structural property damage
Effectiveness: Immediate Exit Trigger
CCTV Integration with Ajax Systems
When Ajax sensors and CCTV cameras share the same trigger logic, every alert arrives with footage, every event is timestamped, and every threat becomes evidence — not just noise.
Alarm-Triggered CCTV + Evidence Workflow
- Event-based recording: Ajax sensor trigger → NVR immediately records only the affected zone — no hours of footage to scrub
- UTC-timestamped logs: Every sensor event logged with sensor name, event type and system state — directly exportable for insurance or police
- Live view on alert: Push notification deep-links to the live camera feed for the triggered zone — see what’s happening before deciding to call police
- MotionCam dual-source: MotionCam sensors send photo burst + CCTV records simultaneously — two visual sources from one event
NVR Integration & SIPKO Design Method
- Single NVR hub: Cameras wired to central NVR (1–4TB), Ajax communicates via relay or direct IP — 14–30 days retention depending on count and resolution
- Zone-matched design: Each Ajax sensor mapped to the exact camera covering the same area — Sensor A fires → Camera A records, not Camera B across the property
- Live commissioning test: Every sensor-to-camera trigger relationship is walk-tested before job close — you get a system we’ve watched work, not one that should
- Brand-agnostic: Ajax handles alarm logic; camera brand runs its own app and recording — two best-in-class systems, one coherent workflow

- Investment property ready: Separate access profiles per unit or per floor — tenants get independent access without visibility into each other’s zones
Accountability for Every User interaction
In a professional environment, “who armed the system” is just as important as “the system is armed.” Ajax provides enterprise-level user management that identifies every action by profile, ensuring full accountability for your residential or commercial site.
Master Admin & Guest Control
The Master account holder maintains absolute control over the hub, with the ability to grant, restrict, or revoke access instantly. No more changing physical locks or resetting hardware codes — everything is handled via secure, encrypted cloud commands.
Searchable Event IDs
Every arm/disarm event is tagged with the user’s name and device ID, leaving a permanent digital paper trail.
Geofence Arming
Remind specific users to arm the system when they leave a defined virtual boundary around the property.
Silent Duress Codes
Special codes that disarm the system but send a silent “under-threat” alert to all other users and monitoring.
Time-Limited Access
Automatically revoke access for contractors or cleaners at a specific hour, day, or after a single use.
💡 Pro Tip: SIPKO recommends setting up uniquely named accounts for each person (e.g., “Cleaner – John” rather than “Guest 1”). This ensures that if an incident occurs, you have a legally defensible log of who was on-site at that exact second.
Industrial Perimeter Protection for Warehouses
Protecting high-value inventory starts long before the warehouse doors. Our Ajax industrial solutions provide wide-area outdoor coverage designed to secure loading docks, storage yards, and factory boundaries without the need for trenching or expensive cabling.
Protect Stock & Equipment
High-value plant machinery, bulk inventory, and raw materials stored in outdoor yards are prime targets. We deploy dual-PIR + microwave sensors that ignore small animals while detecting any human presence in your storage zones.
Wide-Area Wireless Coverage
Ajax Jeweller technology allows our sensors to communicate with the hub up to 1,700 metres away in open ground. This makes it the perfect solution for large-scale factory blocks or distributed industrial parks across Melbourne.
Deterrence Before Entry
Prevent “Smash and Grab” incidents by siren-triggering at the perimeter. Forcing an intruder to flee the property yard before they reach the main warehouse structure saves thousands in structural damage and lost time.
Property-Specific Perimeter Defense
Perimeter security isn’t one-size-fits-all. We tailor our Ajax sensor arrays to suit the specific layout of your Melbourne property, from compact townhomes to expansive gated estates.
Villas & Townhomes
Compact properties require high-precision detection for narrow side paths and small courtyards. We use curtain-style outdoor sensors that create a narrow vertical barrier, ignoring neighbors while watching your boundary.
- Side path curtain sensors
- Gate & Door contacts
Houses & Family Homes
For standard Melbourne blocks, we focus on driveways, rear gardens, and carports. Layered defense ensures you are notified the moment someone steps onto your driveway, long before they reach the building structure.
- Driveway wide-area PIRs
- Rear garden protection
Gated Estates & Acreage
Large properties benefit from Ajax’s long-range Jeweller wireless technology. We secure high-perimeter fences and long access gates up to 1,700 metres from the hub, with zero cabling required across the land.
- Long-range wireless links
- Perimeter fence sensors
Security Isn’t One Device — It’s a Layered System
A single camera or a lone sensor can be bypassed by a determined intruder. True security is built on a multi-layered defense geometry that detects, verifies, and blocks threats before they ever reach your interior spaces.
We don’t wait for a door to be kicked in to tell you there’s a problem. We secure the layers of your property so that an intruder feels the pressure of detection long before they attempt a physical breach.
Outer Layer: Boundary Detection
Detects human presence at the fence-line or driveway using dual-PIR and microwave technology. No one touches your building without being identified first.
Middle Layer: Visual Verification
CCTV cameras and MotionCam sensors provide real-time footage of the perimeter breach, allowing you to distinguish between a delivery and a threat.
Inner Layer: Entry Point Hardening
Magnetic door contacts, shock sensors, and glass-break detectors provide the final, impenetrable line of defense for your windows and doors.
Precision Zoning: Divide & Protect
Your property isn’t a single block — it’s a collection of unique vulnerabilities. Ajax allows us to divide your perimeter into independent “Detection Zones,” each with its own specific alert logic and sensitivity settings.
Early Awareness for Public Boundaries
Control the areas where public land meets your private property. This zone is designed for constant awareness, notifying you of deliveries and visitors long before they reach your front door.
Daytime Intelligence
Silent push notification or internal chime alert when someone enters the driveway.
Night-Time Lockdown
Instant high-intensity siren trigger if a person is detected after midnight.
Auto-Schedule
Pet Immunity
Critical Defense for Blind Spots
Side access paths and rear gates are the most common entry points for intruders. These zones are configured for high-sensitivity detection with narrow “Curtain” sensors to prevent bypassing.
“Curtain” Path Protection
Creates an invisible 12-metre vertical shield along the side of your building.
Zero-Tolerance Trigger
Bypasses all delays; instant full-siren response for unauthorised rear access.
Anti-Masking
Tamper Alert
False Alarms Eliminated by AI Filtering
A security system is only as good as its reliability. We deploy Ajax sensors that distinguish between real threats and environmental noise, ensuring that a gust of wind doesn’t wake you up at 3:00 AM.
LISA Algorithm Filtering
Ajax’s LISA algorithm performs real-time digital analysis of waveforms to distinguish human movement from interference.
Pet Immunity (Up to 20kg)
Proprietary logic ignores cats, dogs, and birds, ensuring your pets can move freely without triggering the siren.
Shadow & Light Filter
Ignores swinging tree shadows, sudden headlights, and cloud coverage changes that trip standard PIR sensors.
Self-Calibrating Logic
The system constantly learns its environment, adjusting the detection threshold during rain or heavy winds.
Built for the Extreme Melbourne Climate
Melbourne’s weather is famous for its unpredictability. Our Ajax outdoor units are engineered to perform in everything from scorching heatwaves to torrential coastal storms.
IP65 Waterproofing
Protected against heavy coastal rain, dust, and salt spray. The internal electronics are fully sealed against humidity and condensation.
Full Ingress Protection

Sun-Shield ASA Housing
Reinforcing the Perimeter: Physical & Digital Fusion
We don’t just alert you to an entry — we reinforce the entry point with intelligent Ajax hardware designed to detect the physical intent of a breach before it occurs.
Driveway & Side Gates
The first physical barrier. We use long-range DoorProtect Plus contacts that cover even heavy metal driveway gates, monitoring for both opening and tampering.
Primary Entrance Doors
Standard contacts only tell you when a door is open. Our reinforced DoorProtect units include shock sensors that trigger if someone attempts to kick or pry the door.
Windows & Glass Perimeters
Ground-floor windows are high-risk. We deploy GlassProtect sensors that use dual-tone frequency analysis to detect the specific sound of glass shattering.
Temporary Perimeter Security for Construction Sites
Vacant sites and high-value materials require rapid-deployment temporary perimeter security that can adapt as the build progresses.
Mobile Deployment Hubs
Our Hub 2 Plus gateways connect via dual SIM 4G/LTE, making them perfect for sites without NBN access. The entire perimeter can be live and armed in less than 4 hours.
Theft Prevention for Heavy Plant
We deploy MotionCam Outdoor sensors to cover expensive machinery and containers. Get visual verification sent to your phone the second an intruder is detected on site.
Large-Scale Coverage for Industrial Hubs
Protecting multi-building warehouses and sprawling industrial zones requires more than just standard sensors. Our enterprise solutions utilise Ajax ReX range extenders to create a unified, impenetrable signal blanket across massive footprints.
Proprietary Long-Range Signal
Jeweller radio technology ensures stable communication up to 2,000 metres away from the main Hub, even through concrete and steel.
Multi-Hub Orchestration
Manage up to 200 devices per system. Perfect for large logistics centres, distribution hubs, and industrial manufacturing plants.

Connect up to 5 ReX 2 extenders per Hub to cover massive estates, ensuring zero blind spots in your wireless network.
Perimeter Security FAQ
Essential information for Melbourne homeowners and businesses considering professional Ajax outdoor protection.
?Does it work with pets like dogs?
Yes. Ajax outdoor sensors use dual-PIR and LISA algorithms to ignore pets up to 80cm tall. As long as your dog isn’t jumping directly into the sensor’s lens, it will remain immune to false alarms.
?How long do the sensor batteries last?
Ajax MotionProtect Outdoor batteries typically last up to 5 years. Even the MotionCam Outdoor (with a built-in camera) lasts up to 3 years on a single set of CR123A batteries, depending on usage.
?Can it tell the difference between trees and humans?
Absolutely. The built-in microwave and PIR sensors must both confirm movement before an alarm is triggered. This “dual confirmation” logic effectively ignores swaying foliage and branches.
?What if someone sprays paint on the lens?
Ajax uses “Anti-masking” technology. If an intruder attempts to cover, paint over, or spray the sensor lens, the system will detect the obstruction and trigger an immediate sabotage alarm on your phone.
?Is professional installation required?
While Ajax is wireless, professional installation by SIPKO is critical. We ensure the height, tilt, and sensitivity are tuned correctly for Melbourne’s climate to avoid false alarms and blind spots.
?Does the system work during a power outage?
Yes. The Ajax hub has a built-in 16-hour backup battery, and all sensors are battery-powered. If your internet goes down, the hub can still communicate via a built-in SIM card/cellular link.
?How many sensors can I add?
Depending on the Hub model, you can connect up to 200 devices. For massive sites, we use ReX 2 Range Extenders to ensure 100% signal coverage up to several kilometres away from the main hub.
?Is the app easy to use?
The Ajax security app is widely considered the best in the industry. You can arm/disarm, view photo verifications, and monitor battery levels in real-time from anywhere in the world.
