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

Smart microrobots that can adapt to their surroundings January 18, 2019
Scientists have developed tiny elastic robots that can change shape depending on their surroundings. Modeled after bacteria and fully biocompatible, these robots optimize their movements so as to get to hard-to-reach areas of the human body. They stand to revolutionize targeted drug delivery.
Waves in Saturn's rings give precise measurement of planet's rotation rate January 18, 2019
Saturn's distinctive rings were observed in unprecedented detail by NASA's Cassini spacecraft, and scientists have now used those observations to probe the interior of the giant planet and obtain the first precise determination of its rotation rate. The length of a day on Saturn, according to their calculations, is 10 hours 33 minutes and 38 […]
Saturn hasn't always had rings January 17, 2019
In its last days, the Cassini spacecraft looped between Saturn and its rings so that Earth-based radio telescopes could track the gravitational tug of each. Scientists have now used these measurements to determine the mass of the rings and estimate its age, which is young: 10-100 million years. This supports the hypothesis that the rings […]
How to rapidly image entire brains at nanoscale resolution January 17, 2019
A powerful new technique combines expansion microscopy with lattice light-sheet microscopy for nanoscale imaging of fly and mouse neuronal circuits and their molecular constituents that's roughly 1,000 times faster than other methods.
Scientists find increase in asteroid impacts on ancient Earth by studying the Moon January 17, 2019
A team of scientists has determined the number of asteroid impacts on the Moon and Earth increased by two to three times starting around 290 million years ago. Previous theories held that there were fewer craters on both objects dating back to before that time because they had disappeared due to erosion. The new findings […]
More animal species under threat of extinction, new method shows January 17, 2019
Currently approximately 600 species might be inaccurately assessed as non-threatened on the Red List of Threatened Species. More than a hundred others that couldn't be assessed before, also appear to be threatened. A new more efficient, systematic and comprehensive approach to assess the extinction risk of animals has shown this.
Emperor penguins' first journey to sea January 17, 2019
New research reveals the previously unknown behaviors of juvenile Emperor penguins in their critical early months when they leave their birth colony and first learn how to swim, dive, and find food.
Feathers: Better than Velcro? January 16, 2019
The structures zipping together the barbs in bird feathers could provide a model for new adhesives and new aerospace materials, according to a new study. Researchers 3D printed models of the structures to better understand their properties.
High-speed supernova reveals earliest moments of a dying star January 16, 2019
An international team of researchers found evidence for the much theorized 'hot cocoon'.
Scientists grow perfect human blood vessels in a petri dish January 16, 2019
Scientists have managed to grow perfect human blood vessels as organoids in a petri dish for the first time. The breakthrough engineering technology dramatically advances research of vascular diseases like diabetes, identifying a key pathway to potentially prevent changes to blood vessels -- a major cause of death and morbidity among those with diabetes.
