Posted on July 9, 2018September 17, 2019 by Wallace Franklin

If you’re looking for the best DIY home security system, wireless or otherwise, one term you will likely come across as you read through manuals is “cross-zoning.” What is cross-zoning? To put it simply, it’s a way to cut down on false alarms. We’ll break down the concept a bit more on this page and demonstrate why it’s a valuable tool for you to try.

What are False Alarms?

Even the best DIY home security system wireless setup may send a signal to the monitoring company, and ultimately to emergency services, when there isn’t an emergency. This is referred to as a false alarm. read more

'Artificial leaf' successfully produces clean gas October 21, 2019
A widely-used gas that is currently produced from fossil fuels can instead be made by an 'artificial leaf' that uses only sunlight, carbon dioxide and water, and which could eventually be used to develop a sustainable liquid fuel alternative to gasoline.
Schools of molecular 'fish' could improve display screens October 21, 2019
Researchers are using liquid crystals to create incredibly small, swirling schools of 'fish.' The fish in this case are minute disruptions in the orientations of the molecules that make up solutions of liquid crystals.
Gimme six! Researchers discover aye-aye's extra finger October 21, 2019
The world's weirdest little primate has gotten even weirder, thanks to the discovery of a tiny extra digit. Aye-ayes possess small 'pseudothumbs' -- complete with their own fingerprints --- that may help them grip objects and branches as they move through trees. This is the first accessory digit ever found in a primate.
Mars once had salt lakes similar to those on Earth October 18, 2019
Mars once had salt lakes that are similar to those on Earth and has gone through wet and dry periods.
Lifestyle is a threat to gut bacteria: Ötzi proves it, study shows October 18, 2019
The evolution of dietary and hygienic habits in Western countries is associated with a decrease in the bacteria that help in digestion. These very bacteria were also found in the Iceman, who lived 5300 years ago, and are still present in non-Westernized populations in various parts of the world. The depletion of the microbiome may […]
Ancient stars shed light on Earth's similarities to other planets October 17, 2019
Earth-like planets may be common in the universe, a new study implies. The team of astrophysicists and geochemists presents new evidence that the Earth is not unique.
Arthropods formed orderly lines 480 million years ago October 17, 2019
Researchers studied fossilized Moroccan Ampyx trilobites, which lived 480 million years ago and showed that the trilobites had probably been buried in their positions -- all oriented in the same direction. Scientists deduced that these Ampyx processions may illustrate a kind of collective behavior adopted in response to cyclic environmental disturbances.
Daily exposure to blue light may accelerate aging, even if it doesn't reach your eyes October 17, 2019
Prolonged exposure to blue light, such as that which emanates from your phone, computer and household fixtures, could be affecting your longevity, even if it's not shining in your eyes. New research suggests that the blue wavelengths produced by light-emitting diodes damage cells in the brain as well as retinas, according to a new study […]
Scientists find early humans moved through Mediterranean earlier than believed October 16, 2019
Scientists have unearthed new evidence in Greece proving that the island of Naxos was inhabited by Neanderthals and earlier humans at least 200,000 years ago, tens of thousands of years earlier than previously believed.
Hubble observes first confirmed interstellar comet October 16, 2019
Hubble has given astronomers their best look yet at an interstellar visitor -- comet 2I/Borisov -- whose speed and trajectory indicate it has come from beyond our solar system. Comet 2I/Borisov is only the second such interstellar object known to have passed through the solar system.
