What Makes a Great Window Sensor Alarm?

I’ve used lots of window sensor alarms over the past year. Some worked great. Some didn’t. The best ones gave me peace of mind. They were loud, easy to set up, and worked when needed.

Most alarms come in two types: magnetic and motion. Magnetic sensors have two parts. One goes on the frame. One goes on the window. If the window opens, they pull apart and the alarm goes off. These are best for bedrooms, kids’ rooms, or anywhere you want fast alerts.

Motion sensors work a bit different. They scan the room for movement. If something moves, they ring. These are great for garages, porches, or wide spaces. My neighbor in Texas uses one to catch raccoons in her shed!

Noise is a big deal, too. A good alarm should be loud—at least 100 decibels. The best ones go up to 120dB. That’s loud enough to wake you up or scare off a thief. I once tested one while watching TV. It made me jump from the couch. That’s what you want!Some window alarms even work with phone apps. They send alerts when you’re not home. I set one up for my mom. Now she gets a ping if someone opens her window. It’s safe, simple, and helps her feel calm.
