Network Coaxial Transmitter - Replaces traditional coax line analog camera systems with network HD cameras, providing a direct upgrade path. Compatible with IP network transmitters, enabling seamless migration from analog to networked surveillance. Passive IP Network Coaxial Transmitter - Built-in surge protection for long-term reliability, guarding the device against voltage spikes and providing an extra layer of protection in variable power environments. Easy To Install - Passive device, no power required. Fast and simple to install, reducing cabling, installation time and cost. Size: 2.0 x 7.5 x 1.8 cm (Cable excluded) / 0.8 x 3.0 x 0.7 in. Long Distance - Uses coaxial lines to transmit real-time digital video, supporting distances up to 220 m. Extends HD video over Coax for flexible deployments. Use scenarios - Upgrading existing CCTV: Convert legacy analog cameras to network HD cameras in schools, offices, or retail without rewiring, preserving the existing coax infrastructure. - Large facility coverage: Extend HD video signals across long corridors or campuses where running new network cables is impractical. - Remote or power-constrained sites: Deploy in locations where near-camera power is difficult, since the transmitter is passive and does not require local power.
