The DOOR GUARD ALARM is a very versatile shock sensor alarm and is ideal for home, office, hotel, or travel. This product is ideal for keeping you and your loved ones safe from harm. It is compact, making it portable so you can take it with you when you travel and it is ideal for anyone for use virtually anywhere.
This alarm requires no installation, simply hang it on any doorknob. Once hung and armed, it instantly detects any vibration. When the alarm is tripped, it will emit a 98dB alert for 20-30 seconds, then will reset in 3-5 seconds.
The sensitivity of the alarm is easily adjusted with a screwdriver and the product can be removed from the doorknob and used as an area light with the switch in the “light” position.
