The eBridge4SPT 4 Port PoE/PoE+ Transceiver Switch is designed for use with eBridge100SPR to deliver data and power over coax cable. eBridge4SPT allows you to upgrade your existing infrastructure by replacing a single analog device with up to four (4) PoE/PoE+ devices. Data transmission and power over the Coax is possible up to 500m. Maximum range from head end to the PoE camera/device is 600m taking into consideration that up to 100m of structured cable may be deployed at each end. Built in IP management allows for remote camera reset, monitoring and reporting via various IP protocols. eBridge4SK enables cost-effective system upgrades and eliminates the costs and labor associated with installing new network cabling.
