The Eazeo system starts with the four-input switcher which allows the connection of up to four digital colour cameras or a specialised low-light black-and-white camera. The monitor displays sequentially full-screen images from any of the cameras and any camera image can be manually selected or viewed as a 'picture-in-a-picture'. It has the additional facility of being able to be triggered by alarms from external sensors or the built-in motion detection. An optional remote control unit is available and the system is expandable to include a further monitor and intercom facilities with remote door opening. Images may be recorded onto either a conventional time-lapse video cassette recorder or a digital recorder which has been specially designed for the Eazeo system.
