For protecting 1 to 2 cameras - For single or dual camera (field installed) protection. Designed for today’s sensitive cameras requiring in-line installation. Utilizing 5 stage multicomponent design (Sidactors, Tranzorbs, MOV’s, resistors and self-resetting “SmartFuses” ) for fast response to high exposure environments. Clamps at 6.0 volts (center pin to shield) and built into durable weatherproof enclosure. Protects both differential and common modes, enabling ground isolation from shield. ( 3V signal clamping units available by request, add suffix “LC”).
