The parts that make an existing cable run usable again: Ethernet-over-coax extenders, AHD/CVI-to-IP converters for hybrid sites, power supplies, pigtails and mounting hardware. Small items, but they decide whether a retrofit needs new cabling.
Ethernet-over-coax pairs carry network and power over existing CCTV cable, so an analogue site can move to IP cameras without pulling new CAT cable through finished walls. Range and bandwidth depend on cable quality; check the pair rating against the camera count on that run.
AHD/CVI-to-IP converters let analogue cameras join an IP recorder during a staged migration, so the customer replaces cameras floor by floor instead of all at once.
Frequently specified: RT-EOC11POE for coax-to-IP with PoE, AHD to IP Convertor for AHD/CVI cameras on an IP recorder.
