{"product_id":"perimeter-intrusion-alarm-scope","title":"Perimeter and intrusion alarm scope for gated residences","description":"\u003cp\u003eAn alarm scope for a finished property, where the walls are up, the driveway is laid and nobody wants a trench through the garden to add security.\u003c\/p\u003e\n\n\u003cp\u003eIt runs on Ajax wireless, which matters here for two reasons. The detectors talk to the panel on their own encrypted radio rather than on cable, so the system goes onto an occupied house without civil work. And because nothing is cast into the building, the whole system comes off the wall and goes with you if you move, rather than being written off as a fixture. If you are renting, that is usually the difference between buying security and not bothering.\u003c\/p\u003e\n\n\u003cp\u003eEverything below is sized for a half acre to one acre compound with a main gate, a boundary of roughly 150 metres, a garden buffer and ground floor openings. Your property will differ and the scope changes with it.\u003c\/p\u003e\n\n\u003ch3\u003eFour things we do differently, and why they matter\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eTwo sensors have to agree before the siren sounds.\u003c\/strong\u003e Outdoor detectors that trigger on a single infrared reading go off for dogs, birds and moving foliage. After a few of those at two in the morning somebody switches the system off, and an alarm nobody arms is not an alarm. These detectors compare readings from two independent sensors before deciding, which is why they can be mounted outdoors at all.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe panel knows when a detector stops answering.\u003c\/strong\u003e Every device checks in on a schedule. If one goes quiet, from a flat battery, a fault or interference, the panel raises that as an alarm of its own. An unsupervised detector that failed months ago is a hole nobody can see.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eYou see a photograph, not just a notification.\u003c\/strong\u003e When a boundary detector triggers, the camera inside it takes a short series of stills and sends them to the phone. The question at two in the morning is whether to call anyone, and a picture answers it faster than a siren does.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCutting the power or the line does not silence it.\u003c\/strong\u003e The panel holds its own battery and carries two mobile SIMs on separate networks alongside the fixed connection. Losing mains, or losing the fibre, does not take the system off the air.\u003c\/p\u003e\n\n\u003ch3\u003eWhat this changes on the running cost side\u003c\/h3\u003e\n\n\u003cp\u003eWe do not publish payback figures. These are the lines an alarm on a finished property touches, and the ones worth measuring before and after.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eTrenching and reinstatement, which a wireless system on a finished property avoids\u003c\/li\u003e\n\u003cli\u003eCallout fees for false alarms, which fall when outdoor detectors are chosen for the position\u003c\/li\u003e\n\u003cli\u003eA separate dialler and SIM for the electric fence, replaced by one system\u003c\/li\u003e\n\u003cli\u003eTime spent checking whether the system is actually armed and working\u003c\/li\u003e\n\u003cli\u003eReplacement of a whole platform because the panel was discontinued, since devices are added to this system over time rather than swapped for a new one\u003c\/li\u003e\n\u003cli\u003eThe system itself, which is unbolted and taken with you if you move rather than written off as a fixture\u003c\/li\u003e\n\u003cli\u003eInsurance terms, which some insurers set against the grade of system fitted\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eNone of these are guaranteed savings.\u003c\/p\u003e","brand":"Urban Eye Security","offers":[{"title":"Default Title","offer_id":46168850596031,"sku":null,"price":0.0,"currency_code":"KES","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/9992\/6719\/files\/scope-perimeter-card.png?v=1789561164","url":"https:\/\/shop.urbaneyesecurity.co.ke\/products\/perimeter-intrusion-alarm-scope","provider":"Urban Eye Security Limited","version":"1.0","type":"link"}
