How the Siren for Arlo Devices Work

You can remotely control the Smart Siren with your Arlo App. Once activated, it can serve the same function as a car alarm. When it detects motion or impact, like a burglar trying to enter your home, it will go off, which should signal neighbors of what’s wrong or you to call the cops.

The audio trigger it has also makes it go off when it detects a loud noise. It’s an effective package thief and home invader deterrent due to its loudness that should alert everyone nearby of the presence of potential criminal activity.

Or it could be a stray cat, dog, or raccoon going through your trash or walking through your porch, but there are settings included that could avoid such false alarms.

Also, about manually triggering the alarm—you can also manually defuse it in case of false alarms or if the culprit has already run away through your app.

What if Your Router is on a Different Floor Than Some of Your Cameras?

You can move the base nearer the cameras you want the siren to activate with. The siren comes from the base. When your camera detects something out of the ordinary in accordance to motion or audio detection settings you yourself put in, the alarm should go off.

Even if your router is far from the cameras, it should still work provided that the signal of the router can reach even the furthest of your cameras. Use a Wi-Fi extended or long Ethernet cable to allow moving the base away from the router and nearer your cams or doorbell video.

Arlo has no guarantees that the cam batteries would be in a condition to allow the siren to work properly. Make sure to use fresh batteries for the best results.

Can You Get an Extra Siren to Alert Neighbors that Something’s Amiss?

The Pro Base alarm feature should be enough for the neighbors to hear and to deter burglars from going through their burglary due to its 100-decibel loudness. It’s like a car alarm, police siren, or ambulance’s wail.

You might be worried because you live in an area where you have large plots of land and the neighbors are far apart. Maybe no one can hear the alarm inside the home in huge territories like Texas.

For extra-large properties, perhaps buying an extra-base with an alarm could make sense, especially if you have extra routers or Wi-Fi services to reach from one end of the home to another. However, most regular middle-class houses find the one Pro Base enough to work with.


The Arlo alarm or 100-decibel siren activates in accordance to the setting you’ve set. You can turn it on by yourself or by motion triggers the same way you can trigger your cameras to activate and record when something moves in their midst.

The alarm serves as your way to alert you or neighbors that you have intruders near your home’s perimeter or the cameras surrounding it. It can even alert you to call the authorities on such would-be burglars while the alarm scares them off or deters them from robbing you.
