IST Video Door Intercom Monitor (V18MONITOR)

When you add an extra IST Video Door Intercom Monitor to your IST Video Door Intercom System, you can answer your door from another location and enable room-to-room intercom communication between monitors. This monitor works just like your original Intercom Monitor; you can see visitors, speak with visitors, and unlock an optional door release mechanism. Furthermore, by integrating multiple monitors into one system, you will create a room-to-room intercom system, which allows communication not only between a monitor and the Door Station, but also between different monitors. The add-on Intercom Monitor wires into the system with the included 30-foot cable. If you need a longer connection, you can connect the components using 4 conductor, 20 AWG minimum wire (sold separately) up to 400 feet. Expandable System: The IST Video Door Intercom System supports up to four Intercom Monitors and four Door Stations total. You can also unlock your door through any Intercom Monitor if you install the optional IST Door Release Mechanism (sold separately). FEATURES: Monitor displays color video of visitors. Adjustable brightness, contrast, volume. Protrudes out only 7/8" from the wall. Optional support for door release mechanism. System supports four monitors total. CONTENTS: Door Intercom Monitor; Cable, 30 Feet; Power Supply; Installation Hardware. NOTE: Requires at least one IST Video Door Intercom Door Station (VIDOOR, sold separately).
