Altronix eBridge4SK kit consists of eBridge100SPR and eBridge4SPT Coax to CAT-5 Ethernet adapters/media converters that deliver data and power over coax cable. The paired set enables fast 10/100 Base-T Ethernet digital communication. eBridge4SPT allows to upgrade the existing infrastructure by replacing a single analog device with up to four (4) PoE/PoE+ devices. eBridge100SPR passes data and sends power over the coax to the eBridge4SPT. Data transmission and power over the Coax are possible up to 300m. Maximum range from headend to the PoE camera/device is 500m, taking into consideration that up to 100m of structured cable may be deployed at each end. eBridge4SK enables cost-effective system upgrades and eliminates the costs and labor associated with installing new network cabling.
