Introduction:
This is an effective low cost vibration door knob alarm that can be used for securing windows or patio doors. When an intruder is attempting to break-in and the door vibrates more than normal or is broken, the vibration sensor triggers the alarm.
Operation:
1) Turn the switch at the left side to 'high' or 'low' to begin operating. A signal will be given out to announce the unit is in good condition. When the glass is hit, knocked or cut by anyone, the siren will sound for 10-20 seconds and then reset.
2) The unit can be set to high or low sensitivity. 'High Sensitive' mode will detect a little vibration. 'Low Sensitive' mode will need a stronger vibration to make the unit react.
Features:
1) Easy to install, just hang on the door knob;
2) No wiring necessary;
3) The unit can be used as a personal property alarm to protect computers, TVs and videos;
4) Portable door security for your peace of mind while traveling;
5) Effective, low cost vibration and shock sensitive alarm that can be used for securing windows and patio doors;
6) Use the sticker at the back of the unit to stick the unit on glass pane, door or window.
