Traditional outdoor alarm sensors are notorious for triggering false alarms from swaying trees, pets, and wind gusts. Ajax MotionCam Outdoor eliminates false triggers using dual independent PIR sensors and the LISA digital algorithm, transmitting encrypted photographic proof of genuine threats to your phone in under 9 seconds.
The Problem with Traditional Outdoor Security Detectors
Protecting property perimeters before an intruder breaks a door or window is the holy grail of physical security. However, traditional outdoor motion detectors earned a terrible reputation across the UK for false alarms. Sun glinting off wet driveways, neighbourhood cats, foxes, and branches swaying in Pennine gales frequently triggered 105dB external sirens at 3:00 AM, infuriating neighbours and forcing homeowners to disable their systems.
Ajax Systems solved this fundamental engineering challenge by re-architecting outdoor motion sensing from the ground up, introducing dual infrared optics and high-speed visual verification.
Dual PIR Sensors & The LISA Signal Processing Algorithm
The Ajax MotionCam Outdoor incorporates two independent passive infrared (PIR) sensors arranged vertically. For an alarm to trigger, both the upper and lower optical beams must detect thermal movement simultaneously.
A domestic pet or fox walking across the patio only cuts the lower beam, which is immediately ignored. Furthermore, Ajax's proprietary LISA digital algorithm performs real-time spectral analysis of heat wave forms. When wind causes bushes to sway, the thermal wave signatures are chaotic and discarded; when a human walks across the lawn, the correlated thermal signature triggers an instant alarm event.
Photo Verification in Under 9 Seconds via Wings Protocol
Detecting motion is only half the battle; knowing whether an alert is real is what gives homeowners true peace of mind. MotionCam Outdoor features an integrated HDR camera equipped with infrared illumination.
When both PIR beams confirm a human intruder, the camera captures an animated series of 1 to 5 high-contrast photos. Using the dedicated Wings radio protocol (separate from the standard 868MHz Jeweller communication channel), these images are delivered to your smartphone app in under 9 seconds, even over weak mobile network connections. You see exactly what is happening before deciding whether to dispatch police or sound external sirens.
Criminals frequently attempt to neutralize outdoor detectors by spray-painting the lens or covering them with cardboard during daylight hours. Ajax MotionCam features intelligent Grade 2 anti-masking sensors that monitor the optical field 24/7.
If an object is placed within 5cm of the lens, or if the sensor is covered with paint or opaque lacquer, an immediate sabotage alert is transmitted to Gary Pearce's monitoring console and the homeowner's smartphone. Coupled with heavy-duty Grade 2 tamper switches that detect if the unit is levered off the wall, it offers commercial-grade perimeter hardening.

Need hands-on trade installation? ADI Communications operates dedicated metropolitan engineering hubs across Yorkshire, Lancashire, and Greater Manchester, providing same-day surveys and guaranteed workmanship.
Across Yorkshire, Lancashire, Greater Manchester, Cheshire, Humberside, Nottinghamshire, and Teesside, homeowners and commercial facility managers rely on ADI Communications for physical low-voltage engineering that performs reliably for 10 to 15+ years. Whether you are researching Ajax Outdoor MotionCam: Eliminating False Alarms with Dual-PIR Photo, planning a domestic security or connectivity upgrade, or diagnosing an intermittent signal or network fault, understanding the physical layer—cabling conductors, optical physics, radio-frequency attenuation, and structural wall fixings—is essential to avoiding costly mistakes.
Unlike national call-centre franchises and lead-generation directories that subcontract work to unvetted handymen using cheap Copper-Clad Aluminium (CCA) wire and indoor-grade plastic plugs, Lead Engineer Gary Pearce carries out every site survey, physical installation, and calibrated meter test personally. With over 25 years of hands-on trade experience since 1999 and formal NVQ qualifications across Aerials & Satellite (Level 1–3), Data Cabling & Fibre (Level 1–4), Electrical (Level 1–3), and CCTV Security Systems, our engineering protocols are built around British Standards (BS EN 62676-4, BS 5839-6, BS 7671, and EN 50131 Grade 2).
01 • Pure Copper Infrastructure
100% Solid Bare Copper Cabling (Zero CCA)
Every metre of external and internal cable we install—whether Cat6/Cat6A Ethernet for PoE security cameras and Wi-Fi 6 access points, or CAI-benchmarked WF100 twin-screened foam-dielectric coaxial cable for Freeview HD and satellite feeds—uses 100% solid 23AWG/24AWG oxygen-free bare copper. Solid copper prevents IEEE 802.3af/at PoE voltage drop over long runs, eliminates high-frequency RF skin-effect attenuation, and resists brittle snapping or galvanic corrosion inside damp exterior junction boxes.
02 • Structural Substrate Anchoring
Engineered Fixings for Stone, Brick & Drywall
Northern and Midland properties span Victorian millstone grit, Yorkshire sandstone, Accrington engineering brick, lime-mortar cobbles, and modern dot-and-dab insulated plasterboard. We match every bracket to the exact wall substrate: heavy-duty hot-dip galvanised Pennine storm brackets and twin stainless-steel chimney lashing cradles for rooftop Starlink and aerial masts; steel-cored CoreFix 100 dot-and-dab bridge anchors and M6 SnapToggle hollow-wall toggles (rated to 120kg) for large-screen OLED/QLED TV wall mounting.
03 • Calibrated Meter Verification
Fluke Networks & Spectrum Analyser Testing
Guesswork has no place in professional telecommunications. Before any job is signed off, we verify physical-layer performance using calibrated instruments: Fluke Networks cable verifiers for Cat6/Cat6A wiremap continuity, pair skew, and PoE load voltage under night-time LED surge; digital RF spectrum analysers measuring Modulation Error Ratio (MER ≥ 32dB) and pre-Viterbi Bit Error Ratio (BER) across UHF Freeview multiplexes; and SpaceX Starlink 110° phased-array sky-obstruction telemetry.
4K ColorVu & TiOC Surveillance
F1.0 super-aperture 24/7 full-colour night vision turrets fitted with IP66 weather-sealed aluminum junction bases and pure copper Cat6 PoE cabling.
SpaceX Starlink Gen 3 Roof Engineering
Non-drill stainless steel chimney lashing cradles and galvanised gable apex brackets rated for 90mph Pennine gales with 0.0% sky obstruction.
Ajax EN 50131 Grade 2 Smart Alarms
Encrypted 2,000m Jeweller frequency-hopping radio with 0.15s MotionCam photo verification, dual-path SIM backup, and £0 monthly fees.

Cat6A Data Cabling & Mesh Wi-Fi
Hardwired Gigabit and 10Gbps Ethernet drops, SWA armoured garden office links, and ceiling-mounted UniFi, TP-Link Deco, and Omada Wi-Fi 6 access points.
Digital TV Aerials & Communal IRS
CAI-benchmarked log-periodic and Yagi aerials aligned by spectrum analyser with 700MHz/800MHz 5G LTE filtering and WF100 copper coaxial cabling.
Domestic Home Priority vs Commercial & Industrial Specification
Over 70% of our day-to-day work across Yorkshire and the North West involves domestic residential homes—terraced properties, semi-detached family houses, detached executive homes, rural farmhouses, and residential apartments. In a domestic setting, homeowners care deeply about two things: rock-solid reliability and spotless aesthetics. Nobody wants ugly white cables draped over roof tiles, trailing across bay windows, or tacked loosely along internal skirting boards. When Gary Pearce installs a 4K CCTV system, SpaceX Starlink dish, Cat6 Ethernet point, or wall-mounted television in your home, exterior cables are matched to your brickwork or render (black, white, or brown UV-stabilised PE sheath), tucked behind rainwater downpipes, and drilled on an upward internal incline with a weather-shedding drip loop and high-modulus silicone seal.
We also provide full installation and troubleshooting support for customer-supplied equipment. Many homeowners purchase a Hikvision, HiLook, Swann, Reolink, Annke, TP-Link Tapo, EZVIZ, Ring, or Eufy kit online or from a retail store, only to discover that working safely at roof height, drilling through 18-inch stone walls, crimping 8-pin RJ45 connectors, or configuring router port-forwarding and NVR storage requires specialist trade tools. Whether you want us to supply and fit a complete trade-grade system or professionally install hardware you have already bought, you receive the exact same calibrated testing and workmanship care.
For commercial clients—including retail shops, hotels, B&Bs, pubs, restaurants, car parks, apartment blocks, student HMOs, warehouses, farms, caravan parks, and construction sites—we scale up to industrial specifications. Commercial deployments incorporate NDAA-compliant Uniview, Dahua WizMind, and Hikvision AcuSense/DarkFighter hardware, 25x–42x optical zoom auto-tracking PTZ domes, dedicated ANPR number-plate recognition lanes, dSCR communal IRS satellite multiswitches, EN 54 / BS 5839-6 Grade D1 interlinked wireless fire detection, and rack-mounted 19-inch Cat6A patch panels—all backed by £10 Million Public Liability Insurance and full RAMS documentation.

Who carries out the installation and diagnostic work at ADI Communications?+
Every survey, installation, and fault-finding visit is carried out directly by company founder and Lead Engineer Gary Pearce. We never sub-contract jobs to third-party agency labourers. Gary holds over 25 years of hands-on experience and formal NVQ qualifications across aerials, satellite, structured data cabling, fibre optics, electrical installations, and CCTV security systems.
Can you install CCTV cameras, Starlink dishes, or smart doorbells that I have already bought myself?+
Yes. Alongside supplying and fitting our own trade-grade Hikvision ColorVu, Dahua TiOC, Uniview, and Ajax packages, we offer a dedicated customer-supplied hardware installation service. We mount your units using trade-grade stainless steel or galvanised fixings, replace flimsy factory patch leads with 100% solid copper exterior cabling, weatherproof all masonry entry points, and configure your mobile apps.
Why do you insist on 100% solid bare copper Cat6 and WF100 coaxial cable instead of cheaper CCA wire?+
Copper-Clad Aluminium (CCA) cable has roughly 55% higher DC electrical resistance than pure bare copper. Over runs exceeding 20 metres, CCA causes severe Power over Ethernet (PoE) voltage drop—making 4K CCTV cameras reboot at night when their ColorVu or infrared LEDs switch on—and suffers rapid oxidation inside damp outdoor junction boxes. Solid bare copper guarantees full IEEE 802.3af/at PoE delivery, 10Gbps bandwidth headroom, and a 15-year+ outdoor service life.
Are there any mandatory monthly subscription fees for your CCTV or Ajax alarm systems?+
No. You own all installed hardware outright from day one with £0 mandatory monthly fees to ADI Communications. Our 4K PoE CCTV systems record 24/7 onto a local Western Digital Purple surveillance hard drive inside your NVR, and both Hik-Connect/DMSS and the Ajax Security System smartphone apps send instant push alerts and live HD video to your phone completely free of charge.
Which UK regions and postcode districts does ADI Communications cover?+
We operate equipped mobile workshop vans across West, South, North, and East Yorkshire (Leeds, Bradford, Wakefield, Sheffield, Huddersfield, Halifax, York, Harrogate, Doncaster, Hull), Lancashire and Greater Manchester (Manchester, Preston, Blackburn, Burnley, Bolton, Wigan, Oldham, Rochdale, Stockport), Cheshire (Warrington, Chester, Crewe, Macclesfield), Humberside and Lincolnshire (Grimsby, Scunthorpe, Cleethorpes), Nottinghamshire, and Teesside/County Durham.
How do you mount heavy TVs safely onto modern dot-and-dab or hollow plasterboard walls?+
On dot-and-dab walls—where 12.5mm plasterboard sits over a 15mm–25mm air gap in front of thermal blockwork—we drill 100mm deep into the structural blockwork and insert steel-cored CoreFix 100 anchors so the steel sleeve bridges the void without crushing the plasterboard. On timber or metal stud walls, we anchor into the studs and deploy heavy-duty M6 SnapToggle steel wing anchors rated up to 120kg.
How do you protect slate and rosemary tile roofs when installing SpaceX Starlink or TV aerials?+
We never bolt brackets through roof slates or clay tiles. On homes with a sound chimney stack, we fit a non-drill stainless steel chimney lashing cradle using twin 5mm steel tension wires wrapped around the stack—distributing wind loads across four courses of brickwork without drilling a single hole into the mortar. On properties without chimneys, we mount heavy-duty hot-dip galvanised stand-off brackets into the solid gable-end masonry below the bargeboard.
What is the best way to get fast Wi-Fi into a garden office, summerhouse, or outbuilding?+
Plug-in powerline adapters fail across separate RCD consumer unit circuits, and domestic mesh nodes cannot push 5GHz signals through double glazing and foil-backed outbuilding insulation. We engineer two permanent solutions: either a direct-burial Steel Wire Armoured (SWA) Cat6A copper cable feeding an internal PoE Wi-Fi 6 access point, or a matched pair of external 5GHz/60GHz point-to-point wireless bridge dishes when a patio or driveway prevents trenching.
Are your commercial and HMO installations fully insured and compliant with UK regulations?+
Yes. ADI Communications carries £10,000,000 Public Liability Insurance, provides full Risk Assessments and Method Statements (RAMS) for commercial sites, and issues formal commissioning certificates and VAT invoices across BS EN 62676-4 (CCTV), BS 5839-6 Grade D1 / EN 54 (wireless fire detection), and BS EN 50131 Grade 2 (intruder alarms).
What warranty do you provide on your installations and repairs?+
Every installation and structural mounting bracket fitted by Gary Pearce is backed by our comprehensive 1-to-3 Year Workmanship and Hardware Guarantee. If any bracket, cable termination, or supplied component experiences a fault under normal operating conditions, we return and rectify it promptly with zero call-out charge.
Regional Field Engineering Standards Across Yorkshire, Lancashire & the North
Every property across Northern England and the Midlands presents distinct environmental, structural, and radio-frequency conditions. On high-altitude Pennine properties across Saddleworth, Holmfirth, Hebden Bridge, Todmorden, Skipton, Ilkley, and Harrogate, rooftop SpaceX Starlink Gen 3 dishes and digital Freeview HD aerials face winter wind gusts exceeding 80 to 90mph alongside driving sleet and horizontal rain. Standard lightweight alloy brackets or single-band chimney straps twist out of alignment during the first autumn gale. That is why our rooftop installations use heavy-gauge 2-inch steel masts, twin 18-inch stainless steel chimney lashing cradles tensioned with 5mm galvanised wire, and hot-dip galvanised stand-off wall brackets anchored into solid mortar courses with M10 bolts.
Inside heritage Victorian and Edwardian stone terraces, converted mills, and rural farmhouses across Leeds, Bradford, Wakefield, Sheffield, Huddersfield, York, Manchester, Bolton, Blackburn, and Preston, 18-inch solid stone internal walls and foil-backed Celotex cavity insulation block 5GHz and 6GHz wireless signals completely. Relying on wireless-only plug-in Wi-Fi boosters or battery-powered security cameras in these properties leads to constant dropouts and missed motion events. By routing discrete, UV-stabilised external or internal 100% solid bare copper Cat6 and Cat6A Ethernet links from your primary router to hardwired ceiling access points (Ubiquiti UniFi, TP-Link Omada, Deco, or eero Pro) and PoE security cameras, we deliver full Gigabit speeds and unshakeable 24/7 recording into every room and outbuilding.
On modern new-build housing estates across Doncaster, Rotherham, Barnsley, Pontefract, Castleford, Warrington, Stockport, Hull, Scunthorpe, Grimsby, Mansfield, and Teesside, internal walls are almost universally constructed from 12.5mm dot-and-dab plasterboard bonded over thermalite breeze blocks or lightweight metal studwork. Hanging a 65-inch, 75-inch, or 85-inch OLED, QLED, or Sky Glass television on standard plastic rawlplugs risks pulling the plasterboard away from the wall. Our TV wall mounting service uses steel-cored CoreFix 100 dot-and-dab anchors that bridge the cavity air gap directly into the load-bearing blockwork, paired with M6 SnapToggle hollow-wall toggles rated to 120kg and concealed in-wall brush plates so not a single HDMI or power lead is visible.
Whether you are booking a domestic home upgrade, an installation of customer-supplied CCTV or Starlink hardware, an emergency coaxial or Cat6 cable splice repair, an independent Openreach NTE5C master socket relocation, or a multi-camera commercial and HMO compliance project, you deal directly with Lead Engineer Gary Pearce from your initial telephone enquiry right through to final calibrated testing and handover.
