VIDEODOMON KITS The VP-709 series of video door phones is an innovative solution designed for single family housing. The ability to configure the basic set from the VP-709's outdoor panels and video monitors is an undoubted advantage of the system. Each basic kit can be enriched with additional external panels and monitors. This functionality is particularly important for large buildings and for a number of entrances. Up to four monitors and two external panels can be grouped within the system. In addition, after connecting additional CCTV cameras, the set can function as a recorder.
