Changes a regular door knob into an extremely effective entry alarm.
In order to obtain simple access to your house, intruders will initially
attempt your door to see if it is opened. This gadget uses dual-sensing
innovation to allow it to secure both metal & wood doors. For a lot of doors
(wood doors with metal handles), the touch sensor will discover an individual
touching the outdoors doorknob and will quickly produce a loud 110 dB alarm
sound to frighten him away and inform you to the tried entry.
Even if the intruder is using gloves, the Pro-Tec-Door Alarm system will trip as
quickly as the outside door handle is touched. For metal doors or those with
plastic or wood door handles, the vibration sensor will trip when door movement
is detected. You can utilize the chime mode in the house to inform you of your
children or guests arriving or in a company to alert you to consumers. Requires
3 AAA batteries (not included).
