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

Saturn's tilt caused by its moons, researchers say January 21, 2021
Scientists have just shown that the influence of Saturn's satellites can explain the tilt of the rotation axis of the gas giant. Their work also predicts that the tilt will increase even further over the next few billion years.
Butterfly wing clap explains mystery of flight January 21, 2021
The fluttery flight of butterflies has so far been somewhat of a mystery to researchers, given their unusually large and broad wings relative to their body size. Now researchers have studied the aerodynamics of butterflies in a wind tunnel. The results suggest that butterflies use a highly effective clap technique, therefore making use of their […]
Immune system mounts a lasting defense after recovery from COVID-19, researchers find January 21, 2021
Study participants continued to improve their antibodies months after initial infection, potentially due to exposure to remnants of the virus hidden in the gut.
Much of Earth's nitrogen was locally sourced January 21, 2021
Scientists show evidence that nitrogen acquired during Earth's formation came from both the inner and outer regions of the protoplanetary disk. The study has implications for signs of potential habitability of exoplanets.
A 'super-puff' planet like no other January 18, 2021
Astronomers discover that the core mass of exoplanet WASP-107b is much lower than previously thought possible for a gas-giant planet.
2020 tied for warmest year on record, NASA analysis shows January 15, 2021
Earth's global average surface temperature in 2020 tied with 2016 as the warmest year on record, according to an analysis by NASA.
COVID-19 reduced U.S. life expectancy, especially among Black and Latino populations January 14, 2021
A new study finds that due to COVID-19 deaths last year, life expectancy at birth for Americans will shorten by 1.13 years to 77.48 years -- the largest single-year decline in life expectancy in at least 40 years.
Climate change has caused billions of dollars in flood damages January 12, 2021
Flooding has caused hundreds of billions of dollars in damage in the U.S. over the past three decades. Researchers found that 36 percent of the costs of flooding in the U.S. from 1988 to 2017 were a result of intensifying precipitation, consistent with predictions of global warming.
'Galaxy-sized' observatory sees potential hints of gravitational waves January 11, 2021
Scientists believe that planets like Earth bob in a sea of gravitational waves that spread throughout the universe. Now, an international team has gotten closer than ever before to detecting those cosmic ripples.
Measurements of pulsar acceleration reveal Milky Way's dark side January 11, 2021
It is well known that the expansion of the universe is accelerating due to a mysterious dark energy. Within galaxies, stars also experience an acceleration, though this is due to some combination of dark matter and the stellar density. In a new study, researchers have now obtained the first direct measurement of the average acceleration […]
