While door jamb reinforcement can be a very effective way of securing your home’s main entry points, there are also alternatives which can offer door security. The door alarm can be the type that emits a sound when a door has been opened. There are also systems available which are ultrasonic, or that don’t make an audible noise when a door has been breached.

The cost for these various door alarm systems can vary, with the ultrasonic models usually being more expensive than the audible alarm models. Regardless of the door alarm type chosen, experts recommend that good quality be at the top of the list.
