The iBNC Series is intended to provide an extra layer of protection for video feeds at externally mounted cameras. In order for the iBNC to perform as designed, the coaxial cable’s shield must be grounded at either the camera/pole or the head end equipment/DVR chassis. No external ground is required. Excess transient voltage energy is dissipated to the coaxial cable shielding where the shield is bonded to ground. Maximum ground resistance is 25 Ohms, 5 Ohms or less is optimum. This cannot be an assumed value and must be measured to assure proper grounding.
The DTK-iBNC28 protects externally mounted analog cameras, when used with the DTK-DP4P or DTK-PVP27B. View iBNC2.8 Product Information
The DTK-iBNCHD provides protection for externally mounted HD-SDI cameras, and at the HD-SDI DVR. View iBNCHD Product Information
