What is a telephone entry system?
A telephone entry system creates a communication link between an external intercom zone such as a front door or entry gate to every telephone in the home. When a visitor arrives and presses the doorbell, a distinctive sound is sent to the phones to alert the homeowner that someone is calling in from the intercom. With a Channel Vision system, the person inside the home can simply pick up any telephone handset and press a key to begin speaking to the visitor. Additionally, the Channel Vision system includes a relay closure to send a signal to an electronic door strike to release the lock on the door or entry gate.
Isn't telephone entry usually just for gated communities?
No. Actually, with improvements in technology teamed with mass production, telephone entry systems have become affordable for most homeowners. Channel Vision telephone entry systems are a cost-effective way to increase security while adding convenience in any home.
