Putting a IP Camera Design for a Condominium Complex that also has 4 - 20 Slip Floating Docks.  In the past on a Private Dock we have used Cat5 Burial Wire under the concrete decking but above the encapsulated foam, zip tie along the way back to a storage enclosure or dock box. We install PoE Switch and a Wireless Link back to the Recorder at the House. Since the is Multi Tenant. i was thinking about installing a NEMA Enclosure next to the Circuit Breaker Box for the dock. Is there NEC codes to follow for low voltage on a Dock?  I keep looking through the NEC Book but mostly contains to High Voltage. Anyone know?
