Ajax wireless perimeter alarm installation across Brisbane, the Gold Coast, and Sunshine Coast. Outdoor motion detectors, 110dB+ sirens, pet-immune sensors, and smart phone integration — stopping intruders before they reach your doors and windows.
Perimeter alarms stop intruders before they reach your doors and windows — cameras only record what happens after. A properly designed perimeter system using outdoor motion sensors, wireless sirens, and smart detection creates a security barrier around your entire property boundary.
Mr Secured has been installing Ajax perimeter alarm systems across Brisbane, the Gold Coast, and Sunshine Coast for over 15 years. We design systems that work with your property's specific layout — whether that's a Queenslander on a corner block, a warehouse perimeter, or a multi-building commercial site.
Our perimeter alarm systems combine 110dB+ outdoor sirens, pet-immune motion detectors, and smartphone integration so you're alerted the moment activity is detected — and can verify it immediately from your phone.
Every installation is carried out personally by owner Jarrod Edwards — no sub-contractors, no call centres.
Mr Secured installs the full range of premium security camera systems and CCTV security systems in Brisbane — from single-service installs to fully integrated ecosystems combining cameras, alarms, access control and intercoms.
Premium 8MP 4K cameras with AI detection, active deterrence and full-colour night vision.
Grade 2 certified wireless alarms with photo verification and smartphone control.
Keyless entry with facial recognition, RFID, PIN or mobile credentials.
See, speak to and unlock for visitors from your smartphone, anywhere.

A perimeter alarm detects intruders at the boundary of your property — before they reach your doors or windows. It combines outdoor motion sensors, wireless detectors, and high-powered sirens to create a protective barrier around your home or business. When triggered, the system immediately sounds a loud alert and sends a push notification to your phone.
The Ajax StreetSiren Outdoor reaches 113 decibels — comparable to a chainsaw heard at close range. At that volume, the alarm is clearly audible for several hundred metres and will alert neighbours immediately. This is the primary deterrent mechanism: most opportunistic intruders will leave within seconds of the siren activating.
Yes. The Ajax MotionProtect Outdoor detector is pet-immune up to 20kg. It uses dual PIR technology to distinguish between small moving heat sources (pets, birds) and human-sized movement. This eliminates false alarms from animals while maintaining reliable detection of actual intruders.
Absolutely — and we strongly recommend it. When a perimeter sensor triggers, your CCTV cameras can automatically start recording a clip and push it to your phone, so you can see exactly what triggered the alarm before deciding whether to call police. Ajax systems integrate directly with Dahua and Hanwha camera systems that Mr Secured installs.
24/7 back-to-base monitoring is optional but recommended for businesses and homes that are often unoccupied overnight. When connected to a monitoring station, a trained operator can view your CCTV footage when your alarm triggers and dispatch a licensed security response if required — much faster than a delayed mobile notification reaching you.
Ajax sensors use long-life lithium batteries with up to 7 years rated lifespan under normal usage. The Ajax Hub app shows you the current battery level of every device in real time, and alerts you well in advance when a battery needs replacing. In over 15 years of installations, battery failures have never been a surprise.

CCTV INSTALLATION GUIDE
Brisbane is one of Brisbane's most prestigious suburbs — home to some of Queensland's finest residences along Racecourse Road and the Eagle Farm precinct. With significant property values and large landscaped estates, professional CCTV camera installation is an essential investment for Brisbane homeowners looking to protect their assets and family.
Every installation starts with a free on-site assessment. Jarrod personally visits your Brisbane property to design a camera layout that delivers complete perimeter coverage — covering entry gates, driveways, garages, pool areas and garden perimeters. Many Brisbane homes feature large blocks with circular driveways, dual-access properties and architecturally significant facades. We design our camera systems to deliver full coverage while respecting the visual character of your home.
For Brisbane's prestige homes — many built on elevated blocks with complex roof structures — our team is experienced with ceiling access, sub-floor cabling and long cable runs. All ethernet cable is routed discreetly through roof cavities and wall spaces, with all exit points sealed and finished to the highest standard.
Brisbane's large lot sizes and long driveway approaches require cameras with excellent zoom capability and wide-angle coverage. Our 4K (8MP) IP cameras capture number plates and facial detail at ranges that standard cameras simply cannot match — critical for properties with long frontages or circular approach roads.
All footage is stored locally on a dedicated NVR (Network Video Recorder) with 30–60 days of continuous storage. No monthly subscription fees and no cloud storage risk. Remote access via smartphone lets you monitor your Brisbane property from anywhere in the world in real time.
Brisbane's prestige properties benefit enormously from a fully integrated security approach. Many clients pair their 4K CCTV system with an AJAX wireless alarm system and keyless access control — creating a complete security ecosystem managed from a single smartphone app. As certified AJAX installers, we design these systems to work seamlessly together with zero monthly monitoring fees required.
