Andrew Spurgeon, Manager, Product Management

iS5 provides a solid, hardened product that meets my utilities needs for a very competitive price. Features such as 1000BaseT Ethernet, fiber optic uplink options, POE, secure protocols for administration, standards-based management and solid user interface provide excellent value for the money. So far, all the units have been working perfectly with no issues, some of them have been in place for over a year.
