Swann SW244-DWM is an advanced security system that provides safety, security, and convenience for your home. With its easy plug-and-play installation, you can have it up and running in minutes. The system includes a doorbell with a built-in camera, a wall-mounted intercom, and a 65-foot cable. The doorbell camera provides a clear black-and-white image of your visitor, so you can see who is at your door before you open it. The intercom allows you to communicate with your visitor without having to open the door, providing an extra layer of security. You can also use the intercom to unlock the door or gate with the touch of a button, making it easy for guests to enter your home.
