## Overview

The Streetwise Pro-Tec-Door Alarm combines cutting-edge UV marking dye technology with a robust 110 dB alarm system, ensuring your home or office is protected like never before. Operating on just 3 AAA batteries, this alarm is designed for easy installation and versatile use, making it an essential addition to your security toolkit.

## Description

Transforms an ordinary door knob into a highly sensitive burglar alarm. In order to gain easy access to your home, burglars will first try your door to see if it is unlocked. This device utilizes dual-sensing technology to enable it to protect both metal & wooden doors. For most doors (wooden door with metal knobs), the touch sensor will detect a person touching the outside doorknob and will instantly emit a loud 110 dB alarm to scare him away and alert you to the attempted entry. Even if he is wearing gloves, the Pro-Tec-Door Alarm will sound as soon as the outside door knob is touched. For metal doors or those with wooden or plastic door knobs, the vibration sensor will detect the attempted forced entry. You can use the chime mode at home to notify you of visitors or in a business to announce customers.

## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    good enough, but not great quality
  

*by K***Y on Reviewed in the United States 🇺🇸 on November 20, 2015*

It works ok.  Nice and loud, the middle setting is the perfect sensitivity for my metal door.  The big problem is that the item bangs against the door and causes the cheap plastic battery door to fall off and the batteries to fall out, every time someone goes in or out.  I'm not talking about someone slamming the door or being rough with the alarm;  the normal amount of force required to normally close the door causes the alarm to fall apart.  Nothing a little packing tape won't fix, but I shouldn't have to do that.

### ⭐⭐⭐ 







  
  
    Not very loud
  

*by P***S on Reviewed in the United States 🇺🇸 on February 9, 2022*

The item works, but it's not very loud. It has two settings - chime and alarm. But neither setting is loud. I don't think it's loud enough to wake me up from my sleep.

### ⭐⭐⭐⭐⭐ 







  
  
    Great warning system.
  

*by R***M on Reviewed in the United States 🇺🇸 on October 29, 2015*

Recently my family home was burglarized, while my mother was home! They got in by breaking a basement window, 8:30am on a Monday. She heard a sound from the next room and found burglars. They sauntered off with jewelry and other belongings. It scares me that she was in the house with those intruders for at least a couple minutes, without even knowing it! I wanted to create a better warning system if such events should happen again. Along with other methods, such as bars on basement windows and a monitored alarm with glass break sensors, I installed this on the basement door. She didn't hear them break the window, but she will hear this! I know this because a garbage truck set if off one morning and gave her heart a little exercise. I changed the sensitivity to low and the next week's garbage pickup didn't set it off. I tested it; any slight change in the door position set it off while set at low.Update: After about couple months the alarm started making a constant noise. It was a warning that the batteries were dying. While that noise was a bit scary and annoying, I really liked that it alerted us that the batteries needed to be changed.
