What is Cross-Zoning?

Posted on July 9, 2018June 26, 2018 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

Ice confirmed at the moon's poles August 21, 2018
Using data from NASA's Moon Mineralogy Mapper instrument, scientists have identified three specific signatures that definitively prove there is water ice at the surface of the Moon.
Massive monumental cemetery built by Eastern Africa's earliest herders discovered in Kenya August 20, 2018
An international team has found the earliest and largest monumental cemetery in eastern Africa. The Lothagam North Pillar Site was built 5,000 years ago by early pastoralists living around Lake Turkana, Kenya. This group is believed to have had an egalitarian society, without a stratified social hierarchy. Thus their construction of such a large public […]
Light from ancient quasars helps confirm quantum entanglement August 20, 2018
New research boosts the case for quantum entanglement. Scientists have used distant quasars, one of which emitted its light 7.8 billion years ago and the other 12.2 billion years ago, to determine the measurements to be made on pairs of entangled photons. They found correlations among more than 30,000 pairs of photons -- far exceeding […]
Carbon reserves in Central American soils still affected by ancient Mayan deforestation August 20, 2018
Deforestation is suspected to have contributed to the mysterious collapse of Mayan civilization more than 1,000 years ago. A new study shows that the forest-clearing also decimated carbon reservoirs in the tropical soils of the Yucatan peninsula region long after ancient cities were abandoned and the forests grew back.
Taking the brain apart to put it all together again August 20, 2018
A new Organ Chip system linked a Brain Chip with two blood-brain barrier (BBB) Chips to recapitulate the interactions between the brain and its blood vessels. This system reacts to methamphetamine exposure just like a human brain, and has allowed scientists to make new discoveries about just how important our blood vessels are for our […]
Nearly two million acres on fire in the United States August 20, 2018
The West Coast of the United States is shrouded in smoke from the 110 large fires (this does not include smaller fires within each complex of fires) that have erupted across the region during this fire season.
DNA analysis of 6,500-year-old human remains with blue eye mutation August 20, 2018
Scientists have discovered that waves of migration from Anatolia and the Zagros mountains to the Levant helped develop the Chalcolithic culture that existed in Israel's Upper Galilee region some 6,500 years ago. "Certain characteristics, such as genetic mutations contributing to blue eye color, were not seen in the DNA test results of earlier Levantine human […]
New kind of aurora is not an aurora at all August 20, 2018
Thin ribbons of purple and white light that sometimes appear in the night sky were dubbed a new type of aurora when brought to scientists' attention in 2016. But new research suggests these mysterious streams of light are not an aurora at all but an entirely new celestial phenomenon.
Stone tools reveal modern human-like gripping capabilities 500,000 years ago August 20, 2018
Research demonstrates that a technique used to produce stone tools that were first found half a million years ago is likely to have needed a modern human-like hand. This links a stone tool production technique known as 'platform preparation' to the biology of human hands, demonstrating that without the ability to perform highly forceful precision […]
Nice sunny days can grow into heat waves -- and wildfires: summer weather is stalling August 20, 2018
Stalling summer weather as we are experiencing right now in the Northern hemisphere can turn into 'extreme extremes' from heat to drought, from rain to flood.
