Do you want to know when someone does something to vibrate your door or grabs the door knob? If so, this inexpensive but quite effective product may be what you're looking for.
The Door Guard Alarm is a very versatile shock sensor alarm. This alarm requires no installation, simply hang it on any doorknob. Ideal for home, office, hotel, or travel. If you're in a motel room, you'd want to know the instant someone tries to open your door. If you have this hung from the doorknob on the inside, you will instantly be alerted!
Once hung, it instantly detects any vibration. When the alarm is tripped, it will emit a 98dB alert for 20-30 seconds, then it will reset in 3-5 seconds. The sensitivity of the alarm can be easily adjusted with a common screwdriver.
The Door Guard can be removed from the doorknob and even used as an area light when you put the switch in the light position.
The vibration alarm is also your flashlight if you need it to be. Just move the switch down to turn on the light. You can light up your immediate area so you can see.
The Door Vibration Alarm is ideal for keeping you and your loved ones safe from harm. It is small and compact, making it very portable. You can bring it when you travel. It is ideal for anyone at home or who travels and can be used virtually anywhere. Use in conjunction with the door stopper for even more security.
Not sure about that shady looking hotel but can't beat the price, now you can feel confident and safe. Uses 2 AAA batteries (not included).
