Why sliding glass doors are often targeted in Savannah

As sought-after as sliding glass doors are to families, they’re also tempting to burglars. There are a couple of reasons why.

During warm temperatures and sunny days, your sliding glass door could be the most-used entryway at your house. You could a pattern of keeping it open so kids can get to the yard on their own accord. Even when you secure the door, determined prowlers can get around it. Here’s how:

Better defend your Savannah home’s sliding glass door

If you want to enhance the security of one of the most vulnerable doors in your Savannah residence, here’s how you can.

  • Install security cameras. When potential invaders see surveillance around your house, they’ll probably try to find an easier target. They won’t want to be caught on camera. You can even choose surveillance systems that actively deter prowlers with lights and sound.
  • Connect door sensors. Incorporate glass break and contact sensors within your integrated security system. The alarm will go off if an unwanted guest tries to intrude or break the glass. Advanced systems will also alert you with communications to your security system’s mobile app.
