A totally self contained telephone system that uses regular telephones and telephone wire. It will run off of outlet power, solar power, car battery or other 12 volt source and also the supplied rechargeable battery. The system is designed with one main telephone ( 2 line preferred but not necessary) and up to 4 " perimeter" phones.
the main unit and the perimeter units are supplied with buzzers and an LED light to allow you to ring the main unit. The buzzer can be silenced if stealth is needed with the LED letting you know someone is buzzing you. The buzzer system can be used to sent Morse Code messages for quiet communication. The main unit is the size of a smart phone while the perimeter units are even smaller.
I will put pictures up of how I have my units stored. The system has been FCC tested at 1/4 mile but it will reach much farther then that. Using a car battery versus the supplied rechargeable battery will boost it's performance.
It is a great comms system for home or bugout location allowing secure communication at a reasonable price.
