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

Traces of ancient rainforest in Antarctica point to a warmer prehistoric world April 1, 2020
Researchers have found evidence of rainforests near the South Pole 90 million years ago, suggesting the climate was exceptionally warm at the time.
Oldest ever human genetic evidence clarifies dispute over our ancestors April 1, 2020
Genetic information from an 800,000-year-old human fossil has been retrieved for the first time. The results shed light on one of the branching points in the human family tree, reaching much further back in time than previously possible.
Hubble finds best evidence for elusive mid-sized black hole March 31, 2020
Astronomers have found the best evidence for the perpetrator of a cosmic homicide: a black hole of an elusive class known as 'intermediate-mass,' which betrayed its existence by tearing apart a wayward star that passed too close.
Where in the brain does creativity come from? Evidence from jazz musicians March 31, 2020
A new brain-imaging study has studied the brain activity of jazz guitarists during improvisation to show that creativity is, in fact, driven primarily by the right hemisphere in musicians who are comparatively inexperienced at improvisation. However, musicians who are highly experienced at improvisation rely primarily on their left hemisphere.
On Mars or Earth, biohybrid can turn carbon dioxide into new products March 31, 2020
Chemists have created a hybrid system of bacteria and nanowires that captures energy from sunlight and transfers it to the bacteria to turn carbon dioxide and water into organic molecules and oxygen. On Earth, such a biohybrid could remove carbon dioxide from the atmosphere. On Mars, it would provide colonists with raw material to manufacture […]
Weighing in on the origin of heavy elements March 30, 2020
Nuclear physicists conducted a physics experiment that utilizes novel techniques to study the nature and origin of heavy elements in the universe.
A Martian mash up: Meteorites tell story of Mars' water history March 30, 2020
Researchers probed Martian meteorites to reconstruct Mars' chaotic history. Their findings suggest that Mars might not have had a global magma ocean.
In Earth's largest extinction, land animal die-offs began long before marine extinction March 27, 2020
Because of poor dates for land fossils laid down before and after the mass extinction at the end of the Permian, paleontologists assumed that the terrestrial extinctions from Gondwana occurred at the same time as the better-documented marine extinctions. But a new study provides more precise dates for South African fossils and points to a […]
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.
Neanderthals ate mussels, fish, and seals too March 26, 2020
Over 80,000 years ago, Neanderthals fed themselves on mussels, fish and other marine life. The first evidence has been found by an international team in the cave of Figueira Brava in Portugal. The excavated layers date from 86,000 to 106,000 years ago, the period when Neanderthals settled in Europe. Sourcing food from the sea at […]
