BST-55
Digital Triax Base Station
Discontinued Product
The DTA-55 / BST-55 is a triax transmission system, using Ikegami’s original super low latency digital transmission to minimize degradation and deliver the full resolution and SNR of the camera head to the base station regardless of the triax cable distance. This new transmission system allows customers to transition from SD to HD while still using their existing triax camera cable infrastructure, saving cost and continuing to use a rugged easy to repair cable/connector type.
