Operates on all non-metallic (wooden) doors with metal knobs.
1. In order to gain easy access to your home burglars will first try your doors to see if they are unlocked.
If a burglar touches your outside doorknob this device will instantly emit a loud alarm to scare him away and alert you to the attempted entry.
Even if he is wearing gloves, the alarm will sound as soon as the outside doorknob is touched.
2. Keep your children safely inside with our Safety Sensor Door Alarm.
When the door knob is touched the alarm emits a loud 120 dB sound letting you know that your child is at risk of leaving.
Have a warning before your child goes out the door.
