Hi, DIYers, Dylan here with Alarm Grid.
Today we're going to be going over,
should I use a motion sensor or a glass break sensor
in my home?
Main thing that is different between the two
is that the glass break, obviously,
is listening for glass break sounds-- if you
have an audible one like this.
There are shock sensors where you place directly
on the window where it picks up the vibration of the glass
breaking.
This one is an audible one, so it doesn't go directly
on the window.
Essentially, where you would mount
this is either on a ceiling, or on a wall
opposite of the windows.
This can pick up a sound of glass breaking
for about 25 feet.
That's the max range on it.
Anything past that, you're testing it a little bit.
25 feet is your max.
Obviously you can detect anything closer.
Main reason you're going to want a glass break--
if anyone can get into a door, get into a window
without opening it, they're likely breaking the glass
or using a cutter.
Cutter is obviously a little bit more
rare, unless you're in a very, very, I suppose,
wealthy area where someone's going
to have that much time and resources to try
to break into the home.
Normally people are going to take a rock, take a crowbar,
shatter the glass, walk right in.
Now, if you shatter the glass and walk right in,
obviously door sensors are out the window.
They don't pick you up.
The glass break is going to be listening
for two tones for that glass.
The first tone is a low thud.
So someone hitting the glass with the object--
their fist, hand, elbow, crowbar, rock, anything
like that.
The second sound is a high pitch of the actual glass breaking
itself.
Once this device picks up both of those tones,
it sets off the alarm and sets off, basically,
signals to Central Station if you have it set up,
or to Total Connect 2.0 if you have that set up.
That's going to notify you the glass break has been detected.
The alarm will be sounding.
The burglar should be scared by the alarm,
and hopefully leaves.
And then that's pretty much good on the glass break.
It's done its job, and you've protected your home.
For the motion, similar idea, but much different.
So obviously, motion isn't going to be listening for anything.
All the motion does is look.
It's looking for heat signatures either passing it
or going towards it.
It's better if it's passing it, because if it picks it up
going by it, it's hitting multiple areas of detection
and gives you a higher likelihood
that the motion's going to pick it up and set the alarm off.
Now, similar idea.
So say if someone breaks into a window, breaks
into a sliding glass door without opening it,
the door sensors aren't going to do much,
because they're not detecting a door or window being opened.
They have no clue what's going on.
Someone can just walk right in.
When they walk right in, motion detector picks them up.
It doesn't matter if a door was opened prior.
It doesn't matter anything like that.
As long as your system is set to Armed Away,
your motion will be active, and it's
going to pick up any heat signature
or movement within the home no matter if a door or window was
opened before, or if you have or have not
had a glass break that's detecting
the same sound of the glass breaking.
The motion has a range of about 35 feet looking forward,
and about 20 feet width.
So from here to there, 20 feet; back and forth, about 35 feet.
As mentioned, the glass break has about a 25 foot radius
for listening for the glass breaking.
With this, as I mentioned as well,
you also want to set it up where it's
in an area where if someone does pass it, they're walking by it.
I'm not sure if you can see this, but on the side
here, this is the range of how the motion sees.
Here's the motion.
Here's it's going out.
As you can see, it has these multiple lines.
So that's what I'm meaning by if someone's walking by this,
they're hitting multiple areas of detection.
Definitely going to get this to pick it up.
If you're walking straight towards it,
it can still pick you up, but you
can see it's going over a lot less areas of protection.
So it's possible it could miss it.
Depends on the sensitivity of the motion, to be honest.
