What is Cross-Zoning?

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

Ancient volcanoes once boosted ocean carbon, but humans are now far outpacing them September 14, 2020
A new study of an ancient period that is considered the closest natural analog to the era of modern human carbon emissions has found that massive volcanism sent great waves of carbon into the oceans over thousands of years -- but that nature did not come close to matching what humans are doing today.
Possible marker of life spotted on venus September 14, 2020
Astronomers have discovered a rare molecule -- phosphine -- in the clouds of Venus. On Earth, this gas is only made industrially or by microbes that thrive in oxygen-free environments. Astronomers have speculated for decades that high clouds on Venus could offer a home for microbes -- floating free of the scorching surface but needing […]
New Hubble data suggests there is an ingredient missing from current dark matter theories September 10, 2020
Recent observations have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why researchers have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in […]
High-fidelity record of Earth's climate history puts current changes in context September 10, 2020
Scientists have compiled a continuous, high-fidelity record of variations in Earth's climate extending 66 million years into the past. The record reveals four distinctive climate states, which the researchers dubbed Hothouse, Warmhouse, Coolhouse, and Icehouse. These major climate states persisted for millions and sometimes tens of millions of years, and within each one the climate […]
How coronavirus took hold in North America and in Europe September 10, 2020
Early interventions were effective at stamping out coronavirus infections before they spread, according to a new study. Combining virus genomics with epidemiologic simulations and travel records, the research shows that in both the United States and in Europe, sustained transmission networks became established only after separate introductions of the virus that went undetected.
COVID-19 study links strict social distancing to much lower chance of infection September 10, 2020
Using public transportation, visiting a place of worship, or otherwise traveling from the home is associated with a significantly higher likelihood of testing positive with the coronavirus SARS-CoV-2, while practicing strict social distancing is associated with a markedly lower likelihood.
Unconscious learning underlies belief in God, study suggests September 9, 2020
Individuals who can unconsciously predict complex patterns, an ability called implicit pattern learning, are likely to hold stronger beliefs that there is a god who creates patterns of events in the universe, according to neuroscientists.
Process that might have led to first organic molecules September 8, 2020
New research identifies a process that might have been key in producing the first organic molecules on Earth about 4 billion years ago, before the origin of life. The process, which is similar to what might have occurred in some ancient underwater hydrothermal vents, may also have relevance to the search for life elsewhere in […]
True size of prehistoric mega-shark finally revealed September 3, 2020
A new study has revealed the size of the legendary giant shark Megalodon, including fins that are as large as an adult human.
Has Earth's oxygen rusted the Moon for billions of years? September 2, 2020
To the surprise of many planetary scientists, the oxidized iron mineral hematite has been discovered at high latitudes on the Moon.
