Description
The Valcom VIP-D640A is a 4-inch, 6-digit PoE IP digital clock that displays hours, minutes, and seconds — NTP-synchronized over your existing network with a single RJ-45 cable for power and data. The 6-digit format is the right choice for environments where second-level accuracy needs to be visible: broadcast facilities, testing centers, operating rooms, and any space where time-to-the-second matters.
The Telecom Spot Expert Review
Most facility clocks show hours and minutes — the VIP-D640A adds seconds, which is a meaningful difference in high-precision environments. Same PoE and NTP infrastructure as the 4-digit VIP-D440A, so it fits cleanly into an existing Valcom IP clock system without additional controllers or wiring. Industrial metal housing and network-managed addressing make it as reliable and manageable as any other network endpoint in the building.
