How to prevent your new house guests from causing false alarms this winter…
You may have seen in the news lately, or even in your house, that there have been a significant increase in the number of large spiders about. This has been put down to the unusually warm weather we have been having this September. It was reported this week that there is set to be a UK home invasion of giant spiders this winter. Due to the milder weather allowing them to fatten up and people leaving windows open they have had easier access to houses. As the weather grows colder these larger spiders will head for homes in order to keep warm. UK spiders are very mild mannered and pose no threat to residents, however they may cause problems with house alarms.
Some older movement detectors have difficulty distinguishing between size and distance. This means that if a spider crawls across a sensor’s lens it will detect what it thinks is a very large object and activate the alarm. If the spider manages to crawl into the sensors itself through the holes (which are commonly found in older units) at the back for cable entry, it will think an enormous object has entered your home and will again activate.
Newer alarm systems have more intelligent sensors which can better determine how close an object is. This means it is less likely to activate for an insect as it knows it is closer to the sensor and is just a small object. The PIRs we use here at Keybury also have sealed backs which prevent insects from crawling inside the detectors. Our ‘Zoom Optics’ detectors receive infrared signals across 3 horizontal height bands as well as 22 vertical zones which allows them to better identify when small creatures get in the way or when there is a genuine intruder. If you have an older alarm system, or do not have an alarm system with us, it may be worth upgrading yours to one of Keybury’s “giant spider proof” alarms to cut down on your false activations this winter.
