Entry Defense Alarm

The Entry Defense is Doberman's most basic unit. It is easy to operate, effective and loud. Using two magnets to form an electrical circuit, the opening of a protected window or door breaks this connection and sets off the 100 dB alarm. Doberman's Entry Defense is priced affordably to protect every room and entryway in your home. It's Simple, effective, and affordable home security for your home or office.
