    KatSar Systems provides system design, wiring, installation and service for your new or existing doorbell system or intercom. Today’s system can be as simple as when a visitor presses the button, the intercom rings your telephone with a distinctive ring to alert you.

    More advanced residential intercom systems can be integrated into a audio system and combined with a miniaturized camera allowing you to view your visitors while talking to them through your telephone. Certain models allow for door or gate release with the push of one button. Whether you are inside the house or enjoying an afternoon in the yard with family and friends, you won’t miss that important person or delivery.
