The most common solution that's applied to improve the home
safety is to install surveillance cameras. However, a house generally consists
of several rooms, thus if you really want to secure your house, you need a
number of surveillance cameras that are placed in several rooms.
Is there no other way to keep an eye on the house? Yes there
is, it's called motion recognition technology, aka motion detector. But
ordinary motion detector can't guarantee the security of the house, even the
home owners themselves sometimes are mistaken as intruders.
This requires new technology that can improve the
effectiveness of the motion detector. According to a startup named Xandem, the
key lies in the use of radio waves. Through Indiegogo, Xandem introduces home
surveillance system which doesn't rely on any surveillance camera named Xandem Home.
Xandem Home is essentially a motion sensors reader. But
uniquely, when it is collected, these sensors can form a network of radio waves
that are connected to one another - if the human eyes can see them, radio waves
network will seem like a spider web.
Then when someone is moving through the invisible radio
waves, the Xandem sensors will immediately recognize him and also keep track of
his location. With the network that's formed by a number of Xandem Home devices
that are placed on several rooms, all the corners of the rooms can be
reached.
Xandem Home also comes along with a hub unit that can be
connected to the router; its function is to connect the entire sensors to the
cloud, allowing users to monitor the situation through a smartphone. The
presence of this hub also opens the potential of Xandem Home for communicating
with the smart home devices, to automate a number of functions based on
specific circumstances.
Through Indiegogo, Xandem Home is offered for $ 475 per
package. Each package includes 10 pieces of motion detection sensors and a hub
unit. Xandem also set monthly fee for its cloud service, but the backers in
this campaign period will be exempt from the subscription fee forever.
