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

Worldwide scientific collaboration unveils genetic architecture of gray matter March 26, 2020
For the first time, more 360 scientists from 184 different institutions have contributed to a global effort to find more than 200 regions of the genome and more than 300 specific genetic variations that affect the structure of the cerebral cortex and likely play important roles in psychiatric and neurological conditions.
As the ocean warms, marine species relocate toward the poles March 26, 2020
Since pre-industrial times, the world's oceans have warmed by an average of one degree Celsius (1°C). Now researchers report that those rising temperatures have led to widespread changes in the population sizes of marine species. The researchers found a general pattern of species having increasing numbers on their poleward sides and losses toward the equator.
New mathematical model can more effectively track epidemics March 25, 2020
As COVID-19 spreads worldwide, leaders are relying on mathematical models to make public health and economic decisions. A new model improves tracking of epidemics by accounting for mutations in diseases. Now, the researchers are working to apply their model to allow leaders to evaluate the effects of countermeasures to epidemics before they deploy them.
Singapore modelling study estimates impact of physical distancing on reducing spread of COVID-19 March 24, 2020
A new modelling study conducted in a simulated Singapore setting has estimated that a combined approach of physical distancing interventions, comprising quarantine (for infected individuals and their families), school closure, and workplace distancing, is most effective at reducing the number of SARS-CoV-2 cases compared with other intervention scenarios included in the study.
Ancestor of all animals identified in Australian fossils March 23, 2020
Geologists have discovered the first ancestor on the family tree that contains most animals today, including humans. The wormlike creature, Ikaria wariootia, is the earliest bilaterian, or organism with a front and back, two symmetrical sides, and openings at either end connected by a gut. It was found in Ediacaran Period deposits in Australia and […]
New genetic editing powers discovered in squid March 23, 2020
Revealing yet another super-power in the skillful squid, scientists have discovered that squid massively edit their own genetic instructions not only within the nucleus of their neurons, but also within the axon -- the long, slender neural projections that transmit electrical impulses to other neurons. This is the first time that edits to genetic information […]
East Antarctica's Denman Glacier has retreated almost 3 miles over last 22 years March 23, 2020
East Antarctica's Denman Glacier has retreated 5 kilometers, nearly 3 miles, in the past 22 years, and researchers are concerned that the shape of the ground surface beneath the ice sheet could make it even more susceptible to climate-driven collapse.
Device brings silicon computing power to brain research and prosthetics March 20, 2020
A new device enables researchers to observe hundreds of neurons in the brain in real-time. The system is based on modified silicon chips from cameras, but rather than taking a picture, it takes a movie of the neural electrical activity.
The right dose of geoengineering could reduce climate change risks March 20, 2020
Injecting the right dose of sulphur dioxide into Earth's upper atmosphere to thicken the layer of light reflecting aerosol particles artificially could reduce the effects of climate change overall, exacerbating change in only a small fraction of places, according to new research.
Fine-tuning radiocarbon dating could 'rewrite' ancient events March 19, 2020
A new paper points out the need for an important new refinement to radiocarbon dating. The research has relevance for understanding key dates in Mediterranean history and prehistory, including the tomb of Tutankhamen and a controversial but important volcanic eruption on the Greek island of Santorini.
