Description: When paired with the IS7121 cordless digital answering system, this two-in-one cordless additional handset combines a versatile phone system with a digital camera for convenience and security at home. Like Caller ID for your front porch, the video doorbell allows you to screen visitors before answering the door without worry of being seen. The system automatically snaps a photo and sends it to the handsets when visitors ring the doorbell. You can then stream video, audio, or both with just two buttons. Many home monitoring systems are bulky and expensive taking up valuable space throughout your home. But with this system, you get a fully featured cordless phone with top surveillance features and one less thing competing for counter space.
