PoE watchdog monitors the state of connected cameras and automatically reboots a faulty one, so nobody has to drive out to the site. VIP ports 1–8 get transmission priority, which makes them the place for the most important cameras. PoE links reach up to 250 metres and the unit runs at −10 to 55 °C.
Mid-sized video surveillance systems where up to 16 cameras connect to one rack-mounted PoE switch, and installers who want the choice of copper or fibre for the uplink. No configuration is needed.

The total PoE budget is 135 W. The combined draw of the connected cameras has to stay within that limit, so add up the wattages from the camera datasheets.
Yes. The two gigabit combo ports work either with an RJ-45 cable or with an SFP module for a fibre connection.
Yes, the housing is 1U high with rack mounting, 440 mm wide and 300 mm deep.
